A variety of weather patterns are expected across the United States over Labor Day weekend. While areas like Lexington, Kentucky are experiencing record-breaking heat with temperatures hitting up to 102 degrees, other regions such as Wisconsin are anticipating cooler weather with highs in the 70s and lows in the 40s, thanks to a passing cold front. Similarly, Indiana is facing extreme heat with heat indices near 100 degrees on Friday but will cool down over the weekend. The Southland, including areas like the Inland Empire and Coachella Valley, will see gradually warming temperatures, reaching up to 109 degrees. Meanwhile, Southeast Michigan will start with a mix of sun and clouds, turning into severe weather with thunderstorms and potential tornadoes before cooling down by Labor Day. Southern California will experience mild temperatures initially but will warm up due to high pressure, leading to an increased fire risk next week.
