Very dangerous and record breaking temperatures across the southwest U.S.
“Records could be in jeopardy in many major cities, with conditions that could prove downright dangerous for older adults, the homeless and other vulnerable populations.
The National Weather Service has issued excessive heat warnings or heat advisories for more than 30 million residents from the Desert Southwest through California’s Central Valley into the weekend.”
“The heat is all thanks to a dome of high pressure, which is bringing clear skies and hot, dry, sinking air. The jet stream is diverting north of the high, carrying all inclement weather and storminess with it. That allows for copious sunshine, making it possible for sunlight to pour down and heat the ground unimpeded.
The science of heat domes and how drought and climate change make them worse
That heat dome will be centered over the Four Corners region on Saturday but should translate east over the Plains on Sunday and reach the eastern United States by Tuesday. Thereafter it could linger, bringing widespread highs 10 to 15 degrees above normal.”
