Nation braces for storms: Hail, winds up to 85 mph!

Severe thunderstorms are forecasted to sweep across the nation's northern corridor beginning Sunday evening, July 27, 2026. These storms are expected to bring damaging winds of up to 85 miles per hour, hail, and heavy rainfall.

The Great Lakes and Ohio Valley regions are identified as having the highest risk for severe weather, as the storm system moves southeast. This activity follows a Saturday night storm in Sioux Falls, South Dakota, which caused widespread power outages with winds exceeding 90 mph.

As the system progresses eastward, the Northeast and mid-Atlantic regions, including the I-95 corridor from New York City to Raleigh, North Carolina, could experience felled tree limbs, power outages, and downpours. Lingering heavy rains through Tuesday evening may also lead to flash flooding in areas from Buffalo to Boston.

Concurrently, much of the central and southern United States will endure hazardous heat. Afternoon temperatures on Sunday and Monday are predicted to be in the upper 90s to lower 100s, with heat indices potentially reaching between 105 and 115 degrees in the Rockies, Plains, Mississippi Valley, and parts of the South.
