953 FXUS01 KWBC 082005 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 404 PM EDT Tue Jul 08 2025 Valid 00Z Wed Jul 09 2025 - 00Z Fri Jul 11 2025 ...The Carolinas into the Mid-Atlantic will see the potential for severe weather and flooding rainfall over the next few days... ...Severe thunderstorms look likely over the Northern to the Central Plains Wednesday and Thursday... ...Storms along a stalling frontal boundary across the Northeast will cool temperatures; the desert Southwest will be heating up as high temperatures in the range of 110-118 deg prompt Extreme Heat Warnings into Thursday. An approaching cold front will stall across the Mid-Atlantic for Wednesday and Thursday. In conjunction with the front serving as a lifting mechanism, rich moisture at the surface will further facilitate an atmopshere capable of supporting high rainfall rates. The Weather Prediction Center has QPF forecasts of 3-4 inches in the next 3 days near southern Virginia, and 2-3 inches from Delaware to the Jersey Shore and around North Carolina. Multiple waves of storms and high rainfall rates means flash flooding is possible. Therefore, WPC has a Slight Risk of Excessive Rainfall from the Mid-Atlantic to North Carolina on Wednesday and Thursday. Shifting to the Plains, another lingering frontal boundary, ample surface moisture and instability, and the arrival of a mid-level trough will set the stage for potential storm clusters capable of high rainfall rates. WPC has issued a Slight Risk for Excessive Rainfall centered around Nebraska and Iowa to account for flooding potential on Thursday afternoon. For the severe weather threat, the Mid-Atlantic and the Carolinas will see hazards of wet micro-bursts and damaging wind gusts. Storms may align in linear organizations as shear remains favorable enough. The Storm Prediction Center has a Slight Risk (level 2/5) for damaging winds across the Mid-Atlantic and North Carolina on Wednesday and a somewhat smaller Marginal Risk on Thursday. For the Plains, the Dakotas southward to the central Plains may see severe hail potential according to the Storm Prediction Center and a few damaging winds are also possible. This is a result of high shear and abundant CAPE. Then, on Thursday, a similar pattern of a trough entering the Plains with abundant instability will support more large hail potential. For fire weather concerns, the Storm Prediction Center has a Elevated fire weather risk across the West, including the Cascades to the Great Basin, as dry fuels and gusty southwesterly surface winds provide favorable conditions for fire spread. Upper level ridging will remain planted across the Southwest. Temperatures will be hazardous to the public and hot weather precautions should be taken through at least Thursday. High temperatures from the California valleys to New Mexico may enter the low 100s.The deserts of Arizona and California are under a Extreme Heat Warning through Thursday with high temperatures nearing record highs and approaching the mid 110s F. The Northeast should see the mini heat-wave end as a front swings into the area with rainfall. The Southeast will see typical warmth and humidity for July, but feel like temperatures in the upper 90s and low 100s could still prompt heat risk hazards to the public.
