148 FXUS01 KWBC 241937 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 335 PM EDT Wed Jun 24 2026 Valid 00Z Thu Jun 25 2026 - 00Z Sat Jun 27 2026 ...Severe weather and flash flooding threats continue across portions of the Continental U.S. the next few days... ...Intense heat begins to wane across most of the West on Thursday; builds across the Southern U.S. through Friday... ...Critical to near critical fire weather risk continues for parts of the Great Basin and Four Corners through the end of the week... Daily threats of scattered severe weather and flash flooding will persist across parts of the country through the end of the week as a summertime weather pattern remains in place. An abundance of Gulf moisture and an unstable air mass will interact with a few slower-moving disturbances and frontal boundaries, setting the stage for several organized clusters of thunderstorms the next few days. The strongest storms could quickly turn severe across the High Plains and portions of the Upper Midwest this afternoon and evening, bringing the potential for damaging winds, large hail, and a few tornadoes. In addition to the severe weather threat, intense rainfall rates in these storms could yield scattered instances of flash flooding, especially from the High Plains to parts of the Lower Mississippi Valley and central Gulf Coast. West of the Rockies, thunderstorms capable of damaging wind gusts and isolated downpours are possible over the Great Basin in response to an influx of moisture around the western periphery of an upper level ridge. On Thursday, the severe weather threat will stretch from the High Plains to the Ozarks with heavy rain and potential flash flooding confined to the central/southern Plains into the Mid-Mississippi Valley. Another round of severe storms is possible for the High Plains on Friday while the risk for heavy rainfall shifts eastward into the Ohio Valley. In contrast to an unseasonably cool and dry air mass encompassing the northern Plains, Great Lakes, Northeast, and Mid-Atlantic this afternoon, intensely hot weather continues across much of the West. This heat will begin to subside Thursday into Friday as a frontal system pushes inland from the eastern Pacific. High temperatures trending 10-20 degrees below normal late week into the weekend will make for a welcomed reprieve from the heat. While the West will begin to cool down, the heat will expand and intensify across the Southern U.S. through the end of the week, with highs soaring well into the 90s to near 100. Low relative humidity, gusty winds, dry fuels, and the potential for lightning from nearby thunderstorms will again lead to critical fire weather conditions across parts of the Great Basin and Four Corners this afternoon and evening. Ongoing fires along with any new fires that develop will have the potential to spread quickly and can exhibit extreme fire behavior. Near critical fire weather will remain a concern through the end of the week given nearby thunderstorm activity and increasing winds with the approach of a Pacific trough.
