Extreme Heat and Flash Flood Risks Across Central and Southern U.S. During Labor Day Weekend
A massive heat dome is expected to bring extreme temperatures to parts of the central and southern Plains, as well as the Mississippi Valley, during the Labor Day weekend. According to AccuWeather, temperatures in cities across Texas, Oklahoma, Missouri, Tennessee, and Nebraska could exceed 100°F (37.8°C), with high humidity making it feel up to 15°F (8.3°C) hotter. Meanwhile, showers and thunderstorms are forecast around the perimeter of the heat dome, affecting regions in the West, Midwest, northern Plains, and Southeast. The National Weather Service (NWS) has issued heat advisories for large portions of the Mississippi, Ohio, and Tennessee Valleys. Additionally, flash flooding risks are heightened in Texas due to heavy rainfall from Tropical Storm Edouard, which has weakened to a tropical depression.
