267 FXUS01 KWBC 061955 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 353 PM EDT Sat Jun 6 2026 Valid 00Z Sun Jun 7 2026 - 00Z Tue Jun 9 2026 ...Multiple rounds of heavy rain and thunderstorms expected for the Central U.S. through Monday... ...Severe weather likely for portions of the Dakotas on Sunday... ...Hot weather across the Plains and fire weather concerns continue for the West... An amplified upper level flow pattern will be in place across the Continental U.S. through Monday, with a upper trough situated across the Pacific Northwest and northern Rockies, and an upper ridge axis across the Plains and Midwest. At the interface of these features will be an organized storm system that will affect the northern Plains through Sunday night. Kinematic and instability parameters are favorable for the development of severe thunderstorms across the western Dakotas on Sunday and into Sunday night, with an Enhanced Risk of severe storms in the latest SPC convective outlook. There is also a Marginal Risk of excessive rainfall for this same general area, but the overall progressive nature of the storms that develop should help to mitigate the overall flooding potential. Speaking of rainfall, the greatest concentration of slow moving storms with heavy downpours is forecast to be across eastern portions of the central Plains on Sunday, and extending to the western Ohio Valley by Monday, where the potential currently exists for 1 to 3 inches of rainfall through Monday night. There is a Slight Risk of excessive rainfall from WPC to account for this. Portions of the central Gulf Coast could also get some slow moving storms with locally high rainfall rates. Lighter rainfall is likely for portions of the Northeast U.S., and also for western Washington and Oregon with onshore flow increasing on Monday ahead of the next Pacific cold front. In terms of temperatures, it will be quite warm from the eastern Foothills of the Rockies to the Dakotas and into the Upper Midwest on Sunday, with highs running 10-20 degrees above average in many cases. It remains hot across the central Plains going into Monday as well, but relief arrives across the Dakotas with a cold front passing though the region. For the East Coast, a slight cool down along with lower humidity is expected across the Mid-Atlantic and the Northeast to start the work week as a moderately strong cold front passes through the region. Across the Intermountain West, fire weather concerns will continue through the weekend and into Monday, with hot and dry conditions along with gusty winds creating a favorable environment for potential wild fires.
