Severe Storms Threaten Millions From Plains to Appalachians in Multi-Day Threat

Meteorologists in the United States warn that a potent upper-level disturbance and surface low-pressure system tracking from the Midwest into the Great Lakes, Ohio Valley, and Appalachians will fuel multiple rounds of severe storms through the weekend. Forecasts issued Friday, July 31, 2026, indicate a moist, unstable air mass ahead of an advancing cold front will support heavy showers, damaging wind gusts, large hail, and isolated tornadoes. The Weather Prediction Center has outlined a level 2 of 4 Slight Risk for excessive rainfall, with localized flash flooding possible, especially across hilly terrain in the Ohio Valley and western Appalachians, as the system moves toward the Mid-Atlantic and Northeast.
