The Best Weather Imagery of June 2015

Chris Dolce
Published: June 29,2015

Meteorologists are often wowed by various satellite, radar and computer model weather images every month. June 2015 was no different, and it provided us with a variety of vivid examples. Below is some of what we thought was the best weather imagery of June 2015. The images range from a thunderstorm complex and a hurricane to wildfire smoke and Saharan dust.

Mesoscale Convective System (MCS)

This first two images are colorized infrared satellite shots of a mesoscale convective system (MCS) in the Midwest on June 22, 2015. This particular MCS was accompanied by a widespread wind damage event known as a derecho.

Blanca's Moisture

Some of the moisture from what was Hurricane Blanca eventually made it to the Desert Southwest, where it helped to bring some rare early-June rainfall. In this satellite image from June 8, 2015, you can see the plume of moisture in white and blue surrounded by dry air depicted in orange to the north and west.

 Saharan Dust

A large plume of Saharan dust is shown in this satellite image of the eastern Atlantic Ocean near Africa on June 15, 2015. This plume of dust eventually made it to the United States about a week later. The black strip across the image is an area where no imagery was available.

 Tropical Depression Bill in the Ohio Valley

While that plume of Saharan dust moved off the Africa coast on June 15, 2015, Tropical Storm Bill formed in the Gulf of Mexico. Amazingly, Bill kept a very symmetrical presentation on satellite imagery all the way to the Ohio Valley. This image shows Bill as a tropical depression centered over Kentucky on June 20, 2015.

Bill's Heavy Rain Swath

This image shows the estimated rainfall amounts across the United States in the seven days ending June 23, 2015. Clearly evident is the swath of rain Bill produced along its path, arcing from Texas and Oklahoma to Missouri, Arkansas, southern Illinois, southern Indiana and Kentucky. The heaviest rainfall amounts are depicted by the orange and red shadings.

Alaska Wildfire Smoke

Widespread wildfire activity produced a large amount of smoke across Alaska in late-June. The milky shadings in this image show the widespread smoke on June 24, 2015. Also of interest is the curly feature in the smoke shown in the upper right.

Canadian Wildfire Smoke in the Lower 48

Heavy smoke from wildfires in Canada moved into Minnesota on June 8, 2015 as shown by the gray and light brown shadings in this satellite image. Eventually that smoke would head more than 1,600 mile east into parts of the Great Lakes, Ohio Valley and Mid-Atlantic.

 Bow Echo With a Commahead

NWS-Mount Holly, New Jersey, Doppler radar with 3D enhancement over southern New Jersey on June 23, 2015 at 7:05 p.m. EDT. Notice the sharp bookend vortex - rotating commahead - in red in the top-center part of the image. This bow echo was responsible for numerous wind gusts from 65-75 mph across southeast Pennsylvania and southern New Jersey downing trees and power lines, and damaging the roof at the Seneca High School gym in Tabernacle Township, New Jersey.

Damaging Storms on Satellite

This visible satellite image shows the bigger picture of the severe storms that impacted the East on June 23, 2015. At one point, at least 770,000 customers had lost power in the region.

Amplified Weather Pattern in Late June

This computer model image shows the amplified weather pattern in the upper atmosphere over the Lower 48 on June 28, 2015.
In the West, a large dome of high pressure brought record warm temperatures for the month of June to several cities in the Northwest. The blue and purple color bands in the East represent a southward dip in the jet stream known as a trough. That trough helped develop a storm system more typical of fall, which brought strong winds, flooding rainfall and cool temperatures.
