This weekend, multiple regions across the United States are experiencing excessive heat warnings, with temperatures soaring above 100 degrees. Phoenix faces an excessive heat watch with temperatures expected to hit 113 degrees early next week, while Bakersfield and East Texas also expect highs in the 90s and 100s, with associated risks of grass fires and heat-related illnesses due to breezy and dry conditions. The National Weather Service has advised staying hydrated, seeking cool shelter, and avoiding sun exposure to mitigate heat-related health risks. Additionally, there are slight chances of scattered showers and thunderstorms in some areas, which could bring temporary relief from the heat but also pose risks of localized flooding and damaging winds. The heat advisories are expected to extend into next week, with possible slight cooling later as cold fronts move through some regions.
