Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 305 AM EDT Fri May 31 2019 Valid 12Z Fri May 31 2019 - 12Z Sun Jun 02 2019 ...Slight risk for severe thunderstorms on Friday across parts of the southern Mid-Atlantic, the southern High Plains, and the Upper Great Lakes... ...Severe thunderstorms and locally heavy rainfall possible for parts of the Central U.S. on Saturday... Showers and thunderstorms are likely along a slow moving cold front in the Southeastern U.S. today. The best chance for strong to severe storms will be across parts of southeastern Virginia and eastern North Carolina where SPC is highlighting a slight risk. The cold frontal passage on Friday should finally bring a relief from the recent record-breaking heat, though daytime highs may still be above average. The western portion of this boundary will stall across southern and western Texas leading to showers and storms across the Southern High Plains on Friday and a slight risk for severe thunderstorms, mainly across southeastern New Mexico and far west Texas. Locally heavy rainfall is possible along the frontal boundary as well. Warm temperatures, as much as 10 to 20 degrees above normal, will continue into Friday across parts of the Northern Plains and Upper Midwest. A cold front dropping through the region on Friday though will bring a threat for severe weather and SPC has highlighted parts of central Wisconsin into western lower Michigan within a slight risk. This cold front will continue dropping south this weekend with strong to severe thunderstorms possible and SPC showing a slight risk for Saturday from eastern Kansas to central Illinois. Storms may contain heavy rainfall and could lead to localized flash flooding within an already over susceptible region due to recent heavy rains across the Central U.S.. Out West, a broad upper level trough will continue to support scattered showers and storms into Saturday across the Interior West and Great Basin. Upper level ridging building this weekend across the region will bring above normal temperatures, as much as 10 to 20 degrees above average in some places from the Pacific Northwest into the northern Rockies and High Plains. To the south, near to below normal temperatures are likely from the Southwest to the southern High Plains as the core of the upper low parks itself overhead.
