Lightning Deaths Traditionally Peak In July: What You Need To Know To Stay Safe

Sean Breslin
Published: June 29,2015

March, April and May are better known for severe weather because they're traditionally the most favorable months for large tornadoes to strike the Plains and Dixie Alley. But it's not until the summer that another severe weather threat becomes most dangerous for millions of Americans.
According the National Oceanic and Atmospheric Administration, July is the month with the most lightning deaths, on average. From 2006 through 2014, an average of 15 lightning fatalities occurred in July, whereas no other month averages more than 11.
"The combination of more thunderstorms, sometimes moving more slowly, in areas where more people are enjoying outdoor activities is why summer is the peak for lightning deaths in the U.S.," said weather.com meteorologist Jon Erdman. "This emphasizes the importance of being weather aware."
(MORE: U.S. Lightning Deaths In 2015)
As of Monday, there have been 13 lightning deaths in the United States this year. NOAA's 30-year statistics show that an average of 20 lightning deaths occur from January through June, and the annual average is 49 deaths.
The 13th lightning death of the year also marked 300 lightning fatalities since the beginning of 2006, NOAA's stats show. Of those deaths, 240 of those have been men, and 60 were women.
NOAA offeres the following advice for staying safe when thunderstorms are present.
  • Keep in mind that no place outside is safe during a thunderstorm. If you hear thunder, lightning is close enough to strike you.
  • When you hear thunder, immediately move to safe shelter; a substantial building with electricity or plumbing or an enclosed, metal-topped vehicle with windows up.
  • Stay in safe shelter at least 30 minutes after you hear the last sound of thunder.

Indoor Lightning Safety

  • Stay off corded phones, computers and other electrical equipment that put you in direct contact with electricity.
  • Avoid plumbing, including sinks, baths and faucets.
  • Stay away from windows and doors, and stay off porches.
  • Do not lie on concrete floors, and do not lean against concrete walls.

If You're Caught Outdoors And Can't Get To Shelter ...

  • Immediately get off elevated areas such as hills, mountain ridges or peaks
  • Never lie flat on the ground
  • Never shelter under an isolated tree
  • Never use a cliff or rocky overhang for shelter
  • Immediately get out and away from ponds, lakes and other bodies of water
  • Stay away from objects that conduct electricity (barbed wire fences, power lines, windmills, etc.)

Alaska Wildfires in June 2015 Have Surpassed June 2004, Which Was a Record Wildfire Year

Chris Dolce
Published: June 30,2015

The number of wildfires and acres burned in Alaska in June 2015 has exceeded what the state saw during the same month in 2004, a year considered the worst for wildfires in the state.
According to the Alaska DNR - Division of Forestry, a combined 1.6 million acres have been burned by 399 separate fires in the state this month through June 29. That is nearly double the number of fires in June 2004, which had 215 wildfires that charred 1.15 million acres.
The Associated Press reported that 314 wildfires remained active over more than 2,265 square miles as of Monday. No new evacuations occurred this past weekend, however residents in some small communities left in voluntary evacuations last week, including elders, children and those that were medically vulnerable.
Widespread smoke across Alaska's interior on June 24, 2015. The red locators show where fires were active on that day.

Most of the fires in June 2004 were located in Alaska's interior, while this June they have been scattered throughout the state, Alaska DNR said. They added that it was unusual to have this concentration of fire starts.
Lightning strikes were a major contributor to the ignition of wildfires in both June 2015 and June 2004. However, Alaska DNR says that June 2015 has had much more lightning than June 2004. In a span of three days from June 21-23, 2015, about 50,000 lightning strikes were recorded across the state.
The largest wildfire in the state is the Iditarod River Fire, which had burned 98,183 acres through June 28. That wildfire and the other top 10 largest wildfires in Alaska through June 28 were all started by lightning strikes.
Active fire locations on June 30, 2015.
When looking at the year as a whole, the number of acres burned still trails 2004 considerably. A massive 6.59 million acres were burned in that record year. That's eight times the average number of acres burned per year in Alaska.

Sleepy Hollow Fire: Residents Return To Charred Homes in Wenatchee, Washington

Eric Zerkel
Published: June 30,2015

Residents in Wenatchee, Washington, returned to their burned homes Monday evening to survey the damage after a massive wildfire reduced entire streets of houses to smoldering ash.
"These were all really nice homes," Wenatchee resident Joan Mullene, whose home survived, told the Associated Press. "It's really devastating."
As many as 24 to 28 houses have been burned in the Sleepy Hollow fire. The wildfire started outside of Wenatchee Sunday afternoon, but winds drove the flames directly toward Wenatchee, creating a nightmarish situation for firefighters who struggled to bring the fire under control, KOMO News reports.
Three firefighters suffered what the AP described as minor injuries, but no residents have been hurt.

Current Radar/Lightning

Due to an ongoing heat wave in the Northwest, temperatures in Wenatchee were still in the 90's as of midnight local time, according to weather.com meteorologist Jonathan Erdman.
"Light surface winds eventually shifted northwesterly up to 15 mph Sunday evening into the overnight hours," said Erdman. "Showers moved over Wenatchee, but only produced a trace of rain, given the dry air in place."
As a result, the fire had reached homes and businesses within hours. According to the Wenatchee World, the first homes burned after 8 p.m. local time.
The flames also spread to businesses, burning through Michelsen Packaging, Northern Wholseale Inc. and the Bluebird fruit warehouse, the Wenatchee World reports. Monday morning, Chelan County Emergency Management alerted residents to shelter in place because of an ammonia leak. Officials began warning citizens as early as midnight Sunday that the leak may happen.
Multiple streets in Wenatchee were evacuated as flames threatened additional buildings. But on Monday night, citizens were allowed back into some areas, where they found nothing but the charred remains of their lives.
Tom Bryant, a resident who had to leave his home at a moment's notice Sunday night as the flames quickly advanced, returned home a day later and saw his vintage Shelby Mustang GT 500 sports car completely destroyed and buried in ash.
"It hurts, but it's just stuff," he told the AP while his wife looked for a missing cat.
Diane Reed and her two daughters returned to the plot of land where their house once stood and found what she called a "war zone," the Seattle Times reported.
“Was this where the closet was?” said Reed's 13-year-old daughter, Erin, according to the Seattle Times. “This is where I grew up.”

Most of Chelan County is mired in moderate drought, as of the last release of the U.S. Drought Monitor, creating abnormally dry conditions. Those conditions are only amplified by the ongoing extreme heatwave in the Northwest.
According to Erdman, temperatures soared to 109 degrees at Wenatchee's airport Sunday.
"That's an all-time record for June, and just one degree shy of the city's all-time record set on July 17-18, 1941," said Erdman.
Wenatchee, Washington, is located more than 100 miles east of Seattle in the central part of the state and is home to more than 30,000 people.

In 24 Hours, Lightning Sparks Three Dozen New Fires In Northern California

Sean Breslin
Published: June 30,2015 

In an area that's as dry as northern California, all it takes is a spark to create a raging inferno.
That's why firefighters were on edge Sunday as thunderstorms moved through the Golden State. With countless dead trees and plants along the parched landscape, every lightning strike was a new opportunity to start a new wildfire.
Storms fire up near the California-Nevada border on the night of Saturday, June 27, 2015.
According to the Los Angeles Times, some 800 lightning strikes happened in a 24-hour span in northern California, initiating about three dozen new fires.
(MORE: Sleepy Hollow Fire Destroys Two Dozen Homes In Washington)
The California Department of Forestry and Fire Protection told CBS San Francisco that the fires were quickly put out, but it's a sign of things to come in a long fire season. More than 94 percent of California is in severe drought, according to the U.S. Drought Monitor, and the state's vegetation is dying out, providing more fuel for the fires.
Conditions have reached such dire levels that firefighters have stopped controlled burns of brush piles, the L.A. Times also reported. These piles of dead vegetation are a fire crew's worst nightmare, as they can allow a blaze to spread quickly, but it's just too dry to safely burn them off, the report added.
California should have a couple of days without stormy weather, but it's possible that the lightning will return after that.
"Although an upper-level high-pressure system will stay in place across the West into this weekend, portions of northern California will be on the periphery of this high where disturbances will rotate through from time to time," said weather.com meteorologist Chris Dolce. "Those disturbances may lead to the development of some thunderstorms, particularly across higher terrain locations, especially late in the week."

While record-smashing heat is searing the Northwest United States and southwest Canada, another heat wave is about to become more widespread in Europe, and may last in some areas into next week.
A woman cools off with a fan displayed on a terrace of a bar during a heatwave in Madrid on June 28, 2015.
Heat records are already being toppled in parts of Spain.
Madrid (central Madrid) set a new June record high for the second day in a row Monday, reaching 39.7 degrees Celsius -- 103.5 degrees Fahrenheit -- edging out their previous June record of 39.1 degrees Celsius set Sunday.
Monday afternoon, Madrid's Adolfo Suarez Madrid-Barajas Airport pushed up to 40 degrees Celsius (104 F), a first for June in records dating to 1945. According to AEMet, four other locations in Spain with records dating to at least the 1950s tied or set new June heat records Monday.
Cordoba, in southern Spain, reached a sizzling 43.7 degrees Celsius Sunday (110.7ºF).
Highs in parts of southern France topped out in the 100s on Tuesday. Cazaux, France, hit 104 degrees on Tuesday afternoon and Dax, France, topped out at 100 degrees.
(FLASHBACK: Europe May Heat Records)
This heat is now spreading and set anchor in some parts of Europe, and it looks like it'll last through the weekend -- if not longer.
The culprit is an area of high-pressure aloft over and near the Iberian Peninsula, expected to expand as far east as the southern Baltics, Belarus and western Ukraine, and as far north as southern Scandinavia.

"Europeans, and the French in particular, have been painfully aware of the dangers of extreme heat since the killer heat wave of July 2003," said weather.com senior meteorologist Nick Wiltgen. According to the United Nations, an estimated 30,000 Europeans (14,000 in France alone) died in that heat wave, making it the deadliest natural disaster of the past 50 years in Europe.
Paris will be sweating through a high of around 39 degrees Celsius (102 F) Wednesday. Tuesday's high topped out in the low 90s.
After a brief break, mainly in western France, the heat will return Friday into the upcoming weekend, and could even linger into early next week. Highs in Paris will hover between 35 to 39 degrees Celsius (95 to 102 F) Thursday through Saturday.

Western Heat Wave Shatters At Least 31 June Record Highs (FORECAST)

Jon Erdman
Published: June 30,2015

A torrid heat wave is easing a bit, but will kick into high gear yet again later this week into the July 4th holiday weekend, and possibly beyond.
June record highs have been broken in at least 31 cities in the Northwest, five of which appear to have tied or broken their all-time record highs. The extreme heat is likely to last into next week and may end up breaking records for longevity as well.

June Record Highs Set

An unofficial weather station located in Hell's Canyon along the Oregon/Idaho border (Pittsburg Landing) recorded an incredible 116 degrees for a high Sunday.
The culprit in this hot setup is a dome of high pressure aloft, surging northwestward to encompass a large area of the western states. The center of this high will shift around through the week ahead, but overall it will remain a dominant feature.
This will allow the sizzling late-June and early-July sun to send temperatures soaring not simply in the typically hot Desert Southwest, but also locations well to the north including the Pacific Northwest, interior Northwest and northern Rockies.

Hot Week Ahead

Highs well into the 90s and triple digits are expected in many lower-elevation locations west of the Continental Divide and inland from the Pacific Coast.

Heat Alerts

This includes much of Nevada, California's Central Valley, the Salt Lake Valley, Idaho's Snake River Plain, much of Oregon's lower elevations east of the immediate coast, and areas to the east of the Cascades in Washington State.
In particular, parts of the Columbia Basin and lower Snake River Valley will see particularly extreme and persistent heat. This includes cities such as Yakima, Kennewick and Walla Walla in Washington as well as Lewiston, Idaho, as noted in the records below. Temperatures will get knocked down a bit into the 90s or low 100s to start the new workweek, but will then surge towards the middle or possibly upper 100s again late in the week.
(FORECASTS: Seattle | Portland | Boise | Salt Lake City)
The extreme heat has even surged north into Canada. Cranbrook, in far southeast British Columbia at an elevation of about 3,000 feet, set a new all-time record high of 98 degrees (36.8 degrees Celsius) Sunday, according to The Weather Network.
Even Revelstoke, British Columbia – 130 miles north of the U.S. border, about 1,500 feet above sea level and better known for skiing – reached an amazing 103 degrees (39.5 degrees Celsius) Sunday.

Current Temperatures

Compared to what the more arid Great Basin is used to, evening and overnight temperatures will be slow to drop, bottoming out in the 70s in the hottest locations.
In that regard, the air mass moving north into the region already has a strong pedigree; Las Vegas recorded a low of 91 on Friday, marking the first time Vegas has ever recorded a daily low in the 90s during the month of June. This happened again Sunday, when the calendar-day low was only 90 degrees. (The previous record-warm daily low in June was 89 on June 29-30, 2003.)
This heat appears to be locked in place well into the week ahead, as the upper-level dome of high pressure remains camped out near the Great Basin. In fact, some interior Northwest locations may see highs in the 100s every day from now into at least early next week.
(MAPS: 10-Day Temperature Forecasts)

Forecast Highs

The hot, dry weather is also causing a high fire danger, as drought conditions have worsened over the Northwest and northern Rockies in the spring. Disturbances riding around the west side of the upper-level ridge and just enough mid-level moisture may trigger isolated, mainly dry afternoon thunderstorms, which may ignite new wildfires.
(MORE: Wenatchee, Washington Wildfire)
In mid-May, Washington Gov. Jay Inslee issued a statewide drought emergency, and spring runoff from winter's paltry snowpack was expected to be the least in 64 years.
Seattle has seen only 8 days with measurable rain since May 1, one-third the average number of such days, according to NWS-Seattle. Portland, Oregon, set a new record June dry streak of 24 straight days through Saturday, according to NWS-Portland.
One of the biggest factors in heat wave deaths is not only the magnitude, but also the longevity of the heat.
  • Seattle will see highs in the middle 80s to low 90s through the holiday weekend and likely into next week. They reached the low 90s on Saturday and may see several more days in the low 90s later this week. On average, they typically see the 90-degree mark only three days a year. 
  • Spokane, Washington may see a couple of days with century-mark highs through the holiday weekend. Only one such day a year is the average, there. Even when not in the 100s it will be at least in the middle or upper 90s.
  • Portland, Oregon last saw triple-digit heat in August 2012. They may see one, if not more such days in this heat wave this week. The city may also make a run at its longest streak of 90-degree days; that was a 10-day streak in 2009.
  • Medford, Oregon will tie its June record for 90-degree-plus days (21 in 1918).
  • Salt Lake City may see triple-digit highs several days into next week. Six days a year reach 100-degrees or hotter in the Salt Lake Valley, on average and as of Tuesday there have been four days.

Epicenter of the Heat
This is a dangerous heat wave. Take safety precautions against the heat.
Those playing or working outdoors, as well as those without access to air conditioning, will face an elevated risk of heat-related illness. According to the U.S. Energy Information Administration, 25 percent of homes, apartments, condos in the states of Idaho, Montana, Utah and Wyoming do not have air conditioning.
Remember to never leave kids or pets unattended in cars and drink more water than usual. Wear light-colored clothing and keep your head and body cooler with a hat. Take frequent rest breaks in shaded or air-conditioned environments.

New Record Highs

Here is a list of the all-time record highs tied or broken (all Sunday, June 28, unless otherwise noted):
  • Chief Joseph Dam, Washington, hit 113 degrees, topping the previous all-time record of 110 degrees most recently set on July 23, 2006. This is located near the town of Bridgeport, in north-central Washington. Records date to 1949.
  • LaCrosse, Washington, tied their all-time record high of 113 degrees, set previously on Aug. 4, 1961. LaCrosse is in eastern Washington, about 40 miles west-northwest of Pullman. Records, there, date to 1931.
  • Chelan, Washington, reached 110 degrees, topping their previous all-time record set just one day earlier (109 degrees). Prior to this heat wave, their all-time record was 106 degrees set most recently on July 22, 1985. Records date to 1890.
  • Omak, Washington, also reached 110 degrees, topping their previous all-time record of 109 degrees set on July 8, 2001. Records date to 1931.
  • Bonners Ferry, Idaho, soared to 105 degrees, eclipsing their previous all-time record of 104 degrees on July 16, 1941. Records date to 1907. 
Here is a rundown of the June record highs tied or broken Sunday:
  • Walla Walla, Washington, hit 113 degrees. According to Weather Underground weather historian Christopher Burt, if validated this reading will establish a new June record high not just for Walla Walla, but the entire state of Washington. That record is 112 degrees at John Day Dam on June 18, 1961. Of course, Sunday's high also crushed the June record of 109 set just a day earlier, which in turn beat the record of 107 set June 23, 1992.
  • Lewiston, Idaho, reached 111 degrees. This broke the previous June high of 109 set on June 22, 1936. Burt says this too may be a new June record for the state of Idaho, surpassing the 110 degrees recorded at six different locations.
  • Boise, Idaho, topped out at 110 degrees. This replaced the previous June high of 109 set June 19, 1940. It also missed Boise's all-time record high by 1 degree, and was the hottest day in Boise since a high of 110 on Aug. 4, 1961.
  • Ephrata, Washington, hit 110 degrees to break the record of 107 set Saturday. Previously 106 was the June record from June 30, 1998. Sunday goes down as the second-hottest day on record in Ephrata behind the 115 recorded Aug. 4, 1961.
  • Pendleton, Oregon, topped out at 109 degrees both Saturday and Sunday. Those readings broke the city's all-time June record high of 108 set June 30, 1924, and June 17, 1961. June records in Pendleton go back to 1893.
  • Yakima, Washington, reached 108 degrees both Saturday and Sunday. Those broke the previous June high of 105 set June 23, 1992, and just tied earlier in June. Official National Weather Service records for Yakima go as far back as 1946.
  • Spokane, Washington, hit 105 degrees Sunday. That broke a record that had only stood for one day – 102 degrees on Saturday. Before this heat wave the June record had been 101 on June 23, 1992; records in Spokane go all the way back to 1881, making this an especially impressive record. Sunday was also the hottest day in Spokane since Aug. 4, 1961.
  • Kalispell, Montana, hit 102 degrees to crush its June record of 97 degrees just set Saturday. The previous June record was 96 set June 22, 1955, and the previous record for earliest 100-degree day was July 6 back in 2007. Temperature records there began in 1899.

Fourth of July Weekend Forecast: Sizzling Northwest, Stormy East

Linda Lam
Published: June 30,2015

Parts of the Pacific Northwest will sizzle this Fourth of July weekend while some in the East will be dodging Mother Nature's fireworks.
The overall pattern that took hold over last weekend – an upper-level ridge of high pressure in the West, and a southward dip in the jet stream in the East – is expected to remain in place through the holiday weekend.
This means much of the West will remain firecracker hot, while the central and eastern U.S. will find scattered showers and thunderstorms that may dampen holiday festivities at times. A few severe thunderstorms are likely as well.
(MORE: Western Heat Wave)
Below you will find the forecast details for each day.

Friday's Forecast

Friday's Forecast

One disturbance will move off the East Coast on Friday, but a stationary front will stay draped from Virginia and the Tennessee Valley into the central Plains.
A chance for scattered showers and thunderstorms exists along and near this frontal boundary. Isolated thunderstorms should also develop in parts of the Desert Southwest, Sierra and Great Basin.
Otherwise, mainly dry weather is expected over most of the Northeast, Great Lakes, Upper Midwest, and northern Plains.
(FORECAST: New York | Chicago | Atlanta | Seattle)
Highs and lows will be close to average for this time of year, except in the West where the abnormally hot conditions will persist.
Numerous record highs are in jeopardy throughout the holiday weekend in the Pacific Northwest inland from the coast, Great Basin, and valley locations of the northern Rockies, where highs in the 90s and 100s will dominate. East of the Rockies, high temperatures will be generally in the 80s and 90s, except in New England, the Great Lakes and Upper Mississippi Valley where highs will be in the 70s.
(MAPS: This Week's Forecast)
Potential Wet Travel:
- Interstate 95 south of Washington, D.C. to Jacksonville, Florida
- Interstate 75 from Cincinnati into south Georgia
- Interstate 40 from North Carolina to Texas and New Mexico

Fourth of July Forecast (Saturday)

Fourth of July Forecast

High pressure over the West will weaken a bit and become contaminated with mid-level moisture.
While parts of the East will see the chance of scattered showers and thunderstorms once again, it does not appear to be a washout, with most areas seeing storms of the hit and miss variety. Parts of the Plains will also see a few thunderstorms, and scattered thunderstorm coverage in the Rockies and Desert Southwest should be greater than Friday.
(FORECAST: Boston | Washington, D.C. | St. Louis | L.A.)
The good news is that the coverage of storms Saturday night will decrease in most areas with the loss of daytime heating.
The greatest chance of wet weather impacting firework displays will be found in parts of the Mid-Atlantic states, southern Appalachians and Plains. Even then, that chance appears less than 50 percent.
The rest of the East Coast, Great Lakes and much of the West will enjoy the best chance of having fireworks shows go off without a weather interruption, assuming it is not too dry in spots in the West for firework celebrations.
(MORE: Lightning Safety Tips)
The heat will continue in most of the West with temperatures up to 20 degrees above average in the interior Northwest and northern Rockies. Highs will once again climb into the 90s and lower 100s, with 60s and 70s along the immediate coast providing a good heat getaway idea.
Highs in the East will remain quite comfortable for early July, with 70s and 80s in the Midwest and Northeast with typical, muggy 90s in much of the Deep South.
Potential Travel T-Storms:
- Interstate 81 from Pennsylvania to Tennessee
- Interstate 40 from North Carolina to Arizona
- Interstate 25 from Wyoming to New Mexico

Sunday's Forecast

Sunday's Forecast

On Sunday, a cold front will slide from the northern Plains into the Upper Midwest, while a stationary front and prominent upper-level disturbance will be over the Ohio and Tennessee Valleys.
As a result, showers and thunderstorms remain a possibility from the Appalachians into the Ohio and Tennessee Valleys as well as into the mid-Mississippi Valley. A few thunderstorms will likely develop ahead of the approaching cold front in the eastern Dakotas, Minnesota and northwestern Wisconsin southwestward into Nebraska. Scattered thunderstorms will also flare up with the afternoon's heat in the Rockies, Desert Southwest, Great Basin and Sierra.
(FORECAST: Pittsburgh | Minneapolis | Dallas | Phoenix)
Highs will again soar into the 90s and 100s in the interior Northwest and northern Rockies,. The immediate West Coast will still be an escape from the worst of the heat.
(MAPS: 10-Day Temperature Forecast)
Locations from the Plains to the East Coast will see temperatures typical for this time of year, with highs mainly in the 80s. Any 90s should be confined to the Southeast, Deep South and central/southern Plains.
Potential Travel T-Storms:
- Interstate 70 from Ohio to St. Louis
- Interstate 65 from Tennessee to Chicago metro
- Interstate 94 in Minnesota, eastern North Dakota
- Interstate 10 in New Mexico and Arizona

Dry Lightning to Increase Wildfire Risk Across Western US, Canada

By , AccuWeather.com Senior Meteorologist
June 30,2015; 11:53PM,EDT
The combination of excessive heat and dry thunderstorms in many areas will add to the wildfire threat in the western part of United States and Canada through much of July.
High temperatures over much of the interior western U.S. will range from 95 to 105 F this week. Some places in the Southwest will get even hotter. Sunday was the hottest June day on record for many areas east of the Cascades in Washington state.
T-storm and Risk for Fires on the Increase for Southwest
The nature of the current weather pattern tends to favor thunderstorm formation, but low doses of moisture in many cases will stop drenching rainfall from reaching widespread areas of the West.
The risk of thunderstorms will diminish in the Northwest by midweek as a punch of dry air moves in from the Pacific Ocean.

However, the risk of thunderstorms will continue in British Columbia, Alberta and Saskatchewan, Canada, and in many parts of the southwestern U.S.
According to AccuWeather Western Weather Expert Ken Clark, "With the onset of the monsoon season, the chance of fires has greatly risen in the West."
The western U.S. monsoon is associated with the northward spread of tropical moisture, mainly from Mexico. This moisture then becomes trapped beneath a lingering high pressure system. Daytime heating, combined with the moisture produces thunderstorms. How moist the air is near the ground determines whether or not significant rain is able to reach the ground before evaporating.

AccuWeather Severe Weather Center: Information on High Fire Risk Areas

According to the U.S. National Interagency Fire Center, there was an average of 10,600 wildland fires started by lightning during the period from 2001 to 2013.
Activities such as fishing, camping or hiking as thunderstorms rapidly develop during the midday and afternoon hours could be dangerous. Storms over the high country in the West tend to spring up faster than storms in the East where the elevation is generally lower.
The number of deaths from people struck by lightning while fishing and camping in the U.S. dwarfs that of golfing a NOAA report stated.
"Lightning can strike miles away from a thunderstorm with and without rain," Clark said.
Because of the ongoing heat and low humidity, in addition to being a potential target for lightning when in wide open places, people need to be extremely careful with campfires, outdoor power equipment and parking vehicles over high brush.
"Lightning along with man, accidental or deliberate, are the two main causes of wildfires in the West," Clark said.
According to the National Interagency Fire Center, humans cause an average of 62,100 fires in the U.S. each year.
In western Canada, it has been a rough wildfire season already, AccuWeather Senior Meteorologist Brett Anderson said.
"The smoke from fires in British Columbia and Alberta is being blown downstream into parts of the Upper Midwest and occasionally farther to the southeast," Anderson said.
Thus far this year, there have been 1,158,432 hectares burned in Canada, this compared to 399,070 hectares through late June last year, according to the Canadian Interagency Forest Fire Centre.
Smoke from western Canada fires can bee seen in this NASA satellite photo from Sunday, June 28, 2015.
The smoke has been contributing to rounds of poor air quality in the Midwest and to some extent dimming sunshine, producing hazy conditions and making for colorful sunsets as far downstream as parts of the Atlantic Seaboard.

Parts of western Canada will experience a couple of rounds of thunderstorms this week. A few of the storms will bring significant moisture at the local level, but many may not.
The same is true for the southwestern U.S., which will have near daily storms. As humidity levels rise in the Southwest, the chances of getting a drenching storm versus a dry storm will increase this month.
By the time the moisture reaches the Northwest, a higher percentage of the storms will bring little or no rainfall.

Rounds of Showers, Severe Storms to Swipe at Eastern and Southern US Through Friday

By Brian Lada, Meteorologist
June 30,2015; 11:49PM,EDT
Two disturbances tracking eastward from the Plains will bring bouts of showers and thunderstorms to the Ohio Valley, East and South through the rest of the week.
The first of the disturbances is expected to take a more northerly track early in the week, while the second swings father south late in the week, shifting the axis of the heaviest showers and storms.
Breaking: Storms Target Northeast Tuesday Evening
According to AccuWeather Senior Meteorologist Alex Sosnowski, through Wednesday, showers and thunderstorms will stretch from New England to the Deep South.
"Some of the storms will be locally severe with strong wind gusts, hail and flash flooding," Sosnowski said.

This includes parts of the Interstate 64, I-70, I-77, I-80, I-81, I-85 and I-95 corridors.
A brief tornado could also be spawned by a couple of the strongest and longest-lived thunderstorms.
"The metro areas of many major cities could be hit by a disruptive storm or something more severe," Sosnowski said. "This includes Cincinnati, Pittsburgh, Philadelphia, New York City, Charlotte, Atlanta, and Washington, D.C."

By Thursday, the second disturbance will enter the picture, taking a more southerly path.
As a result, the main corridor of showers and storms will shift south, allowing some drying to expand from the Great Lakes region to New England.

This second disturbance is also likely to bring the heaviest rain of the week and the risk of flooding to the Tennessee Valley, the southern Appalachians and part of the southern Atlantic Seaboard.
Nashville and Knoxville, Tennessee, and Louisville, Lexington and Bowling Green, Kentucky, may end up receiving 1 to 2 inches of rain on Thursday alone.

"The ground in many places is saturated, so any rain is going to be considered excessive by a lot of folks, especially in light of one of the wettest Junes on record," said AccuWeather Meteorologist Joe Lundberg.

Rivers are likely to swell from the rapid rainfall rate, leading to flooding in unprotected low-lying areas located near the banks of rivers across the region.
Even through the rain is not expected to be as heavy heading into Friday, any additional rainfall from showers and thunderstorms could spark more flooding issues due to the heavily saturated ground.
Showers and thunderstorms will not end in the East with the conclusion of the week, carrying over into the holiday weekend.

The Fourth of July is not expected to be a complete washout anywhere in the East, but showers and thunderstorms can still lead to interruptions in parades, cookouts and firework displays across a large swath of the East.
Areas most likely to experience thunderstorms or drenching downpours will stretch from the southern part of the Ohio Valley and the Tennessee Valley to the central and southern Appalachians and the middle part of the Atlantic coast on Saturday evening. However, that zone could shift farther north or south, due to weak steering winds.

Rare Leap Second to Make June 30 Longest Day of the Year

By Katy Galimberti, AccuWeather.com Staff Writer
June 30,2015; 11:47PM,EDT
Tuesday, June 30, will be the longest day of the year by exactly 1 second.
In order to keep timing with Earth's slowing rotation, one second will be tacked on to the end of the day. The leap second is a way of balancing Coordinated Universal Time with the gravitational tug of war between Earth, the moon and the sun, NASA said.
While many celebrated the "longest day of the year" on Sunday, June 21, as summer officially kicked off, the length was referring to the number of daylight hours, not solar time.
Flying over East Asia, astronauts on the International Space Station (ISS) took this night image of the Korean Peninsula. (Flickr Photo/NASA)
A typical day consists of 86,400 seconds in UTC time. However, each solar day is about 86,400.002 seconds long. To make up for the difference, the leap second was introduced.
Still, figuring out when a leap second will be needed can be unpredictable. Factors such as El Niño, seasonal and weather variations, as well as deviations in oceans, groundwater and ice storage can alter the length of each solar day.
"In the short term, leap seconds are not as predictable as everyone would like," said Chopo Ma, a geophysicist at Goddard and a member of the directing board of the International Earth Rotation and Reference Systems Service. "The modeling of the Earth predicts that more and more leap seconds will be called for in the long-term, but we can't say that one will be needed every year."
