Record Heat and Flood Threats Hit U.S. Regions

A persistent pattern of heat and humidity is affecting much of the U.S., with several regions experiencing near-record or record-breaking temperatures. The Northeast is seeing temperatures rise from the 70s to near 90°F by Thursday, along with high humidity and late-day thunderstorms before a brief weekend cool-down. The Southeast continues with highs in the lower 90s, heat indices reaching 100-105, scattered storms, and a weak cold front bringing rain by Friday. The Carolinas face elevated flood risks from slow-moving storms through Tuesday, followed by oppressive heat and humidity later in the week. In the Southwest, Phoenix remains under an Extreme Heat Warning with highs up to 115°F and increased fire weather concerns. Much of the interior West and Plains will have a brief break from the heat before another prolonged heat wave and heightened fire danger begin later in the week.
