Record-Breaking Heat to Scorch 22 U.S. States This Week
A significant heatwave is set to impact 22 states across the U.S. this week, with temperatures expected to exceed 90°F (32°C) for approximately 50 million people and 100°F (38°C) for 11 million more. The most intense heat will be concentrated in the Intermountain West, Plains, and South. Notable highs include 103°F (39°C) in Las Vegas, 102°F (39°C) in Fresno, and 117°F (47°C) near Death Valley. Phoenix is forecast to reach 109°F (43°C), temperatures more typical of mid-summer. This heatwave is driven by a transient heat dome caused by weaker jet stream winds. Drought conditions, already affecting 60% of the U.S., are expected to exacerbate the situation, particularly in states like Colorado and Utah, where extreme drought persists.
