Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 324 PM EDT Tue Sep 08 2020 Valid 00Z Wed Sep 09 2020 - 00Z Fri Sep 11 2020 ..Widespread weather impacts expected across the Western to Central U.S. over the next two days.. ...The early Season Winter Storm to continue into Wednesday across the Central Rockies into the Central High Plains with heavy snows likely... ...Heavy Rains and isolated Flash Flooding possible across portions of the Southern to Central Plains Wednesday into Thursday... ...Much Below Average Temperatures expected across the Central to Southern Plains Wednesday and Thursday... ...An Elevated to Critical Fire Weather Threat will continue into Wednesday across much of the West Coast... The early season winter storm affecting the Central Rockies into the Central High Plains will move only very slowly tonight through much of Wednesday, spinning in place across the four corners region. Widespread heavy snows are likely across the Central Rockies and extending into the Central High Plains of southeast Wyoming, the Nebraska Panhandle, eastern Colorado into northeast New Mexico. This system will begin to move more to the northeast on Thursday, with a diminishing heavy snow risk for the Central Rockies and Central High Plains. To the southeast of the Heavy snow region, heavy rains are likely to develop across areas of West to Southwest Texas Tuesday night into Wednesday morning, expanding northward later Wednesday into Thursday into north central Texas, central Oklahoma and Kansas. Rainfall across these regions has been below average over the past two weeks. This will reduce the potential for flash flooding, although there still is the chance of isolated flooding issues over the next two days given the heavy rain potential. In addition to the heavy snow and rain threat from the Rockies into the Plains, temperatures are expected to be much below average across these areas over the next two days. High temperatures on Wednesday are expected to be 30 to 35 degrees below average across large portions of the Southern to Central Plains from eastern New Mexico/western Texas, across much of Colorado, Kansas, Nebraska and Wyoming. Temperatures will begin to moderate across these areas on Thursday but remain 20 to 25 degrees below average Strong winds on the western side of the winter storm have brought dangerous and life threatening fire weather conditions to large portions of western U.S. from the desert Southwest, through the Great Basin, much of California into the Pacific Northwest. An elevated to critical fire weather threat will continue across much of these area through Wednesday. Diminishing winds are possible across these area by Thursday, bringing some relief to the ongoing fires and fire weather threat.
