Over 100 million Americans face dangerous heat conditions this weekend as a heat dome moves eastward. Heat advisories span the Northeast, with heat indices 10-15°F above average. The Southeast and Tennessee Valley will experience the most severe and persistent heat, potentially exceeding 115°F. Vulnerable populations, including the elderly, children, and outdoor workers, are at increased risk of heat-related illnesses. The heat dome, intensified by climate change, is causing widespread heatwaves and exacerbating conditions like 'corn sweat' in the Midwest, while also leading to flash flooding and wildfire warnings in other regions.
