Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 250 AM EDT Wed Sep 10 2025 Valid 12Z Wed Sep 10 2025 - 12Z Fri Sep 12 2025 ...There is a Slight Risk of excessive rainfall over parts of southeastern Florida... A front will be lingering over Florida through Friday. Tropical moisture will pool over Florida and the Central Gulf Coast, aiding in the development of showers and thunderstorms that will bring heavy rain to Florida and along the Central Gulf Coast. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over southeastern Florida 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. A wave of low pressure will move along the front over the Atlantic, streaming moisture westward into parts of the Eastern Seaboard, producing light rain along the coast as far north as New England by Wednesday night. In addition, the flow of moisture off the Western Gulf will trigger showers and thunderstorms over the southern tip of Texas through Friday. An upper-level low over Northern California will produce light rain and embedded thunderstorms over parts of the Northwest, Northern California, and Great Basin through Thursday evening. Also on Thursday, the showers and thunderstorms will move into parts of the Northern High Plains, Northern/Central Rockies, and on Friday, over parts of the Upper Mississippi Valley. Furthermore, smoke from wildfires has prompted Air Quality Alerts over parts of the Northwest. Ziegenfelder Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
