Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Thu Jul 10 2025 Valid 12Z Thu Jul 10 2025 - 12Z Sat Jul 12 2025 ...Multiple rounds of strong to severe thunderstorms are expected to impact the Northern and Central Plains into the Upper Midwest with excessive rainfall threats through the next couple of days... ...Scattered late-day thunderstorms linger along the East Coast... ...Major to locally extreme heat risk across portions of the Southwest for today... A summer weather pattern with upper-level disturbances ejecting from the northern Rockies will support multiple rounds of strong to severe thunderstorms across many locations in the northern and central parts of the Great Plains through the next couple of days, as the disturbances interact with a lifting warm front and a lee-side trough. The thunderstorms are triggered during the afternoon today over the northern Plains where the severe weather threat is greatest, before traveling east into the upper Midwest where the excessive rainfall threat is greatest. Severe wind gusts and isolated large hail are possible with these thunderstorms. By Friday, a reinforcing cold front will push the greatest threats of severe weather and heavy rainfall farther east into the Midwest, upper Midwest, and into the central Plains. By early Saturday into Saturday morning, strong thunderstorms could be popping up over the central High Plains on the trailing portion of the front as a high pressure system brings cooler and drier air from western Canada into the northern High Plains. Along the East Coast, scattered late-day thunderstorms are expected each day as a lee-side trough remains in place across the interior Mid-Atlantic. Although the threat of heavy rainfall and severe weather are expected to be lower than in the past couple of days, some of the stronger and slower-moving storms could result in localized heavy rain and flooding issues. These scattered thunderstorms are also expected to extend across the interior Southeast into the Deep South through the next couple of days at least. The western portions of New England could also see some strong storms today before more stable air filters into the area on Friday. A retrograding upper ridge will support above average temperatures across the West over the next couple of days. Major to isolated extreme HeatRisk is expected for much of the Southwest today before temperatures begin to moderate this coming weekend. Heat-related impacts are also possible in and around southern Georgia and northern Florida over the next several days. Meanwhile, elevated thunderstorms over dry soils will contribute to elevated fire danger over the Four Corners region today.
