US · Published Jul 27, 2026
A widespread thunderstorm system is expected to bring damaging winds, hail, and heavy rainfall to the northern United States starting Sunday evening, July 26,
The Great Lakes and Ohio Valley regions are at the highest risk as the storms, fueled by heat and humidity, move southeast. Wind gusts could reach up to 85 mph, with lightning and downpours likely to disrupt Monday evening commutes. The storm system, which previously caused power outages in Sioux Falls, South Dakota, will continue eastward, impacting areas from Buffalo to Boston with prolonged heavy rains and flash flooding through Tuesday evening. The Interstate 95 corridor, including cities like New York and Raleigh, is also expected to experience severe weather conditions.

Impact & Risks

The storm system poses significant risks, including damaging wind gusts, hail, and flash flooding. Power outages and felled tree limbs are possible, particularly in the Great Lakes and Ohio Valley regions. Urban areas and locations with poor drainage, such as Buffalo, Boston, and parts of New England, are at heightened risk of flash flooding. Travel disruptions are anticipated along the Interstate 95 corridor, affecting major cities like New York and Raleigh. Additionally, hazardous heat conditions with heat indices exceeding 105–115°F (40.5–46°C) are expected across the central and southern U.S., compounding risks for those outdoors.
