Scorching Summer Temperatures Threaten Record-Breaking Heat Across Half the Country

A dangerous heat wave is sweeping across a wide swath of the U.S. this week, with many locations feeling like full-on summer in spring.
Dozens of record high temperatures are expected across the West, Midwest, and Northeast.
Major cities like New York and Washington, D.C. will experience temperatures 10 to 20 degrees above normal, in the 80s, increasing health risks and fire dangers.
The hot weather arrives unusually early and is lasting unusually long, signaling a long, hot summer ahead for much of the country.
