Extreme Heat and Weather Shifts Hit Western U.S.

Much of the western and southern United States is under extreme heat warnings, with areas like Southern California, Arizona, Southern Nevada, the Bay Area, and Idaho seeing temperatures soar into the upper 90s and 100s. Heat advisories are in effect across the interior West, while residents are urged to stay hydrated, avoid sun exposure, and monitor local forecasts. In contrast, the Carolinas and Texas are experiencing milder temperatures in the mid-80s and upper 70s, though isolated thunderstorms are possible. Arizona may see enhanced rainfall at the start of June due to remnants of Tropical Storm Alvin, following reports of both unusual warmth and lingering snow in the region. A cooling trend is expected to begin early next week, offering some relief from the heat. Authorities continue to advise precautions against both extreme heat and sudden weather changes.
