Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 402 PM EDT Thu Aug 14 2025 Valid 00Z Fri Aug 15 2025 - 00Z Sun Aug 17 2025 ...Rounds of scattered thunderstorms expected to impact portions of the Northern Plains to the Eastern U.S. and Southern U.S. through the next couple of days with chances of flash flooding and locally heavy rain... ...Isolated dry thunderstorms brings risk for fire weather concerns for the northern Great Basin... ...A couple of days of heat across the Central Plains, and major to locally extreme HeatRisk is forecast for northern to central Florida... A slow moving cold front over the Northern Great Plains will continue to move eastward towards interior Mid-Atlantic over the next few days, promoting chances for scattered showers and thunderstorms across parts of the Northern Great Plains, Eastern U.S. and Southern U.S. With sufficient moisture and warm air in the mid-levels, expect chances for multiple rounds of locally heavy rain and flash flooding. Areas along the Carolina coast and Upper Midwest have been placed under a Slight Risk (Level 2/4) of Excessive Rainfall for today into Friday. The Upper Midwest will continue to experience prolong chances for showers into the weekend, allowing for the risk for excessive rainfall and possible flooding to linger. A upper level high pressure system will move over the Northern Great Basin bringing chances for some isolated dry thunderstorms, strong winds, and dry conditions. This will create elevated risk for fire activity across the Great Basin, Northern Rockies, Southern California, and Sierra Nevada today into Friday. Warm temperatures continue to push towards the Midwest and Central U.S. into parts of Eastern U.S. the next few days, as the cold front brings cooler temperatures over the High Plains and Great Basin going into the weekend. Across parts of Florida, a slight increase of heat and humidity is enough to raise HeatRisk into Major and locally Extreme levels through the next couple of days as the Bermuda High builds westward into the Sunshine State.
