Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Sun Sep 22 2024 Valid 12Z Sun Sep 22 2024 - 12Z Tue Sep 24 2024 ...A low pressure wave will bring showers and possible severe weather across the central High Plains this morning... ...Rounds of heavy rain and embedded thunderstorms are expected to stretch from the south-central Plains through the mid-Mississippi Valley, Midwest, and into the Ohio Valley for the next couple of days... ...Locally heavy rain and strong thunderstorms moving across the interior Mid-Atlantic this morning... Much of the active weather for the next couple of days will continue to be focused in the vicinity of a slow-moving frontal boundary stretching from the south-central Plains through the mid-Mississippi Valley, Midwest, and into the Ohio Valley. The strongest thunderstorms are expected to traverse the Texas and Oklahoma Panhandles early this morning, and then weaken during the day as they move farther east. Rounds of heavy rain and embedded thunderstorms can also be found this morning across the central Plains into the Midwest, followed by addition showers and thunderstorms forming and moving across Lower Michigan during the day today. By Monday, a low pressure wave is forecast to organize along the front and move northeast across the south-central Plains. Showers and embedded thunderstorms can be expected to accompany the low as well as the frontal boundary. By Tuesday morning, showers and embedded strong thunderstorms are expected to move across the Midwest toward the Ohio Valley as the low pressure center tracks across the region. Across the interior Mid-Atlantic, a subtle upper-level disturbance is delivering a round of heavy rain with strong to locally severe thunderstorms moving from north to south this morning. Meanwhile, recent wet weather in the vicinity of Cape Cod is lingering into this morning. As the slow-moving coastal cyclone begins to slide further out into the Atlantic, the rain is forecast to end during the day today. The high-elevation of central Colorado is waking up to some wet snow due to an influx of colder air associated with the upper low. The upper low will lift into the southern Plains, allowing much of the western U.S. to remain dry for the next couple of days with near normal temperatures. Colder air will surge down the Plains behind the front but 90s will be common in the afternoon across the South into the interior eastern U.S. ahead of the front.
