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.

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.

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.

High pressure aloft, dry, sinking air and generally light winds will allow stifling heat to build.
Wednesday, the heat will ramp up considerably in France, the U.K., Belgium, the Netherlands and western Germany, as well as parts of southern Norway, southern Sweden and Denmark.

Fortunately for the U.K., a cold front will sweep in by Thursday, limiting the truly excessive heat to a couple of days. Their friends across the English Channel won't be so fortunate.
Meteo France warned the country may experience its hottest temperatures in almost nine years: "The major heat waves that hit France in the past generally occurred later in the summer."

Code orange heat alerts ("vigilance orange") have been issued by Meteo France for a large swath of central and northeast France. Code orange is the second-highest level on the four-color hazard scale adopted by national meteorological services in most European countries.
"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.
The worst and most persistent heat will spread from Spain and France into Belgium, Germany, Switzerland, Austria, the Czech Republic, Slovakia, Hungary, Poland, western Ukraine, Belarus and Lithuania through early next week.

A cold front may bring some heat relief by early-mid next week from The Netherlands and Belgium into Germany, Poland, the Czech Republic, southern Scandinavia and the Baltics.
However, that front may stall out before ever bringing relief to southern Europe.
"The latest (long-range forecasts) suggest the ridge and heat will persist across central Europe and Iberia through the month (of July)," said Leon Brown, chief meteorologist based in the U.K. for The Weather Company.
If your travel plans take you to Europe over the next 7 to 10 days, be prepared for the heat. Limit exposure during the hottest times of the day, take frequent breaks, and drink plenty of water to stay hydrated.
