929 FXUS01 KWBC 100703 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 302 AM EDT Thu Sep 10 2026 Valid 12Z Thu Sep 10 2026 - 12Z Sat Sep 12 2026 ...Thunderstorms and locally heavy rainfall likely from the Central Plains to the Ohio Valley, and across the Southeast... ...Severe weather possible from the Upper Midwest to Central Plains on Friday... ...Major to Extreme HeatRisk continues across the Southern Plains to the lower Mississippi Valley late this week... A cold front will be the focus for widespread showers and thunderstorms from the Ohio Valley into the Central Plains on Thursday. Locally heavy rainfall and strong to locally severe weather is possible. WPC highlights areas from western West Virginia into eastern Kentucky within a slight risk of excessive rainfall, where heavy rainfall fell overnight and areas are particularly more susceptible. The front sinks into the Southeast and stalls on Friday, with widespread showers and storms expected across the Southeast to Tennessee Valley and parts of the southern Mid-Atlantic with locally heavy rainfall possible. A cold front dropping into the northern tier of the U.S. will drive showers and thunderstorms across the Northern-Central Plains and the Upper Midwest on Friday. The greatest threat with this system will be severe weather and the Storm Prediction Center has a slight risk for severe thunderstorms all along this boundary as it moves through. Locally heavy rainfall is also possible, especially across portions of northern Minnesota and the U.P. of Michigan. Upper level ridging parked over the South will continue to bring widespread heat threats to especially the Southern Plains to parts of the lower Mississippi Valley through the period. Widespread major to extreme HeatRisk is forecast especially across parts of Texas where a dangerous heat wave has been relentless. The above cold front into the Southeast on Friday may bring some relief to northern areas, but Texas heat will continue into this weekend. Monsoonal moisture around the west side of this heat dome will bring a shower and storm threat to the Southwest through the period as well.
