Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 216 PM EDT Wed Sep 24 2025 Valid 00Z Thu Sep 25 2025 - 00Z Sat Sep 27 2025 ...There is a Slight Risk of excessive rainfall over parts of the Western and Central Gulf Coast on Wednesday and over the Southwest on Thursday and Friday... A front extending from the Great Lakes southwestward to western Texas will move to the Northeast Coast, Mid-Atlantic, and the Central Gulf Coast by Friday. Moisture flowing northward from the Gulf will pool along the front over the Western Gulf Coast to the Ohio/Tennessee Valleys, producing showers and thunderstorms with heavy rain over the two regions. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over the Western Gulf Coast to the Central Gulf Coast and over the Ohio/Tennessee Valleys through Thursday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas the most vulnerable. On Thursday, showers and thunderstorms will move to the Mid-Atlantic/Southeast Coast, as well as the Central Gulf Coast. On Friday, the showers and thunderstorms will continue over the southern Mid-Atlantic and Southeast. Meanwhile, an upper-level low moving over Southern California will stream moisture into the Southwest on Thursday, producing heavy rain. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Southwest from Thursday through Friday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas the most vulnerable. On Friday, the upper low will continue to stream moisture into the Southwest, producing another round of heavy rain. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Southwest from Friday through Saturday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas the most vulnerable.
