Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 345 PM EDT Sat Jun 08 2024 Valid 00Z Sun Jun 09 2024 - 00Z Tue Jun 11 2024 ....Dual threats of severe thunderstorms and flash flooding this evening through Saturday night across the central High Plains into the southern Missouri... ...Temperatures will be above average for the West and Southeast while it will be cooler than average from the central Plains into portions of the Great Lakes and Northeast through Monday... Higher end threats for severe thunderstorms and flash flooding will exist this evening into early Sunday morning across the central U.S. Anomalous moisture is already in place from the central High Plains region, eastward across Kansas into southern Missouri near a cold front in the region. Thunderstorms will increase in coverage and intensity over eastern portions of Colorado and southern Missouri through the remainder of the evening and favorable wind shear will support severe thunderstorms. The Storm Prediction Center has an Enhanced Risk (level 3 of 5) of severe thunderstorms extending from eastern Colorado into western Kansas through Sunday morning, while a Moderate Risk (level 3 of 4) of flash flooding is in place by the Weather Prediction Center over southern Missouri. Multiple rounds of thunderstorms will favor the potential for several inches of rain through Sunday morning. The cold front over the central U.S. is expected to continue advancing south into the southern Plains and east into the southern Mid-Atlantic region on Sunday, bringing cooler temperatures to the central U.S. Forecast high temperatures on Monday are expected to be about 20 degrees colder compared to the expected high temperatures for today. Cooler than average temperatures are also expected for the Great Lakes region where reinforcing cold fronts will move through the region through Monday in addition to showers and thunderstorms. Across the western and southeastern U.S., warmer than average high temperatures are in the forecast through Monday, although a break is coming from some of the excessive heat experienced over the past few days across California, the Desert Southwest and Texas. A cold front will move through the West over the next couple of days which will bring some relief from the high temperatures along with an increasing coverage of showers and thunderstorms. A Marginal Risk of severe thunderstorms (hail and wind) is forecast by the Storm Prediction Center over portions of Idaho, Montana and Wyoming for Sunday ahead of an upper level trough which will help to drive the cold front inland.
