Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 500 PM EDT Sun Oct 11 2020 Valid 00Z Mon Oct 12 2020 - 00Z Wed Oct 14 2020 ...Post-Tropical Cyclone Delta to deliver heavy rain to parts of the East Coast through Monday... ...Severe thunderstorms are possible over parts of the Central Plains and Upper Midwest this afternoon and tonight... ...Rain and high-elevation snow for Pacific Northwest and Northern Rockies... Post-Tropical Cyclone Delta is forecast to continue to weaken slowly, but will continue to produce heavy rain from the Southeast into the Mid-Atlantic. The heaviest rainfall amounts are expected to fall in the southern and central Appalachians through Monday morning. Some flooding has already occurred in those areas. As the heavy rain associated with Delta moves up the coast, mainly localized areas of flash flooding will be possible, with urban areas, roads, and small streams being the most vulnerable. Meanwhile, a cold front moving across the Central U.S. will produce showers and thunderstorms in the Upper Midwest. Some of the thunderstorms could be severe in portions of the Central Plains and Upper Midwest through early Monday morning. Damaging winds and large hail are the primary threats, but isolated tornadoes will be possible as well. The cold front will also break a stretch of much above average temperatures in the Southern Plains, with somewhat cooler conditions expected early this week. Critical fire weather conditions today will give way to an elevated fire weather risk on Monday in portions of the Plains as gusty winds linger in the wake of the front. Further to the west, additional systems moving into the Pacific Northwest and Northern Rockies will produce rain, with some snow at the higher elevations. One round of precipitation will begin to subside on Monday morning, with another round beginning Monday Night and Tuesday.
