Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 337 PM EDT Fri Jul 05 2019 Valid 00Z Sat Jul 06 2019 - 00Z Mon Jul 08 2019 ...Heavy showers and thunderstorms, some capable of producing severe weather and flash flooding, are expected across the central and northern High Plains, and also portions of the Ohio Valley and Northeast through the first half of the weekend... ...Seasonably hot and humid weather is expected across much of the South, with dry conditions continuing for much of the West... A wavy frontal boundary will gradually settle southeast across the central Plains, Midwest and the Northeast going into the weekend which will provide a large area of scattered showers and thunderstorms. The areas seeing the greatest potential for severe weather, including large hail and damaging winds will be across the central and northern High Plains in the lee of the Rockies for this evening and again on Saturday as multiple waves of low pressure interact with favorably moist and unstable air for numerous showers and thunderstorms. Some heavy rainfall totals are expected as well, and some flash flooding will also be possible in conjunction with the severe weather. Meanwhile, portions of the Ohio Valley and Northeast will also see an increasing threat for severe weather and some flash flooding on Saturday and going through Saturday night as the aforementioned front arrives and interacts with a very warm, moist airmass pooled across much of the southern and eastern U.S. The Storm Prediction Center and Weather Prediction Center have highlighted Slight Risks of severe weather and excessive rainfall respectively to address these hazards. Much of the South is expected to see typical summertime conditions with generally hot and humid weather, and some localized potential for afternoon and evening showers and thunderstorms. Temperatures across much of the southern and eastern U.S. will tend to be near normal going through the weekend, with temperatures across the Midwest and the northern Plains a bit below normal given the anticipated frontal passage. Meanwhile, in the West, it will be generally dry with very little in the way of rainfall potential. Temperatures will be generally near normal, except somewhat below normal along the immediate West Coast and also across the Pacific Northwest in the wake of a weak cold front.
