Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 249 PM EDT Wed Sep 09 2020 Valid 00Z Thu Sep 10 2020 - 00Z Sat Sep 12 2020 ..The early season winter storm will be winding down over the Central Rockies... ...Heavy Rains and isolated Flash Flooding possible across portions of the Southern and Central Plains and Mid-Atlantic... ...Below Average Temperatures to continue across the Central to Southern Plains Thursday and Friday but not as cold as in past days... ...An Elevated to Critical Fire Weather Threat will continue into Thursday across much of the West Coast... The slow moving mid to upper level low that has been responsible for the early season winter storm through the Rockies and Central High Plains will be winding down on Thursday. Winter weather will be confined to the Central Rockies tonight into Thursday where additional heavy snows are possible. The much below average temperatures that this system has also been responsible for from the Rockies into the Plains will continue to moderate over the next two days. Temperatures are expected to remain well below average Thursday and Friday across much of the Central to Southern Rockies into the Central to Southern Plains but temperatures are not expected to be as below average as in past days. Some relief on tap for the recent fire weather conditions across the West over the next two days as winds are expected to continue to diminish. However with temperatures remaining above average and relative humidities low, an elevated fire weather threat will continue across large portions of the West coast from California into the Pacific Northwest. A slow moving frontal lying south to north across the Southern Plains will be the focus for heavy rainfall Wednesday night into Thursday from central Texas, northward into eastern Kansas and western Missouri. Heavy rains have fallen over the past 24 hours across the Southern Plains from west central Texas into central Oklahoma and southeast Kansas. Additional rainfall potential across these areas will pose a flash flood threat Wednesday night into Thursday. Heavy rains and isolated flash flooding also possible over the next two days in the vicinity of a stationary frontal boundary forecast to lie along the Southeast and Mid-Atlantic coast. Portions of the Mid-Atlantic have seen above average precipitation amounts over the past several weeks, making them more susceptible to flash flooding.
