Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 118 PM EST Wed Feb 19 2020 Valid 00Z Thu Feb 20 2020 - 00Z Sat Feb 22 2020 ...Additional rains likely across flooded regions of the South through Thursday... ...A broad region of Arctic high pressure will encompass much of the central and eastern U.S. over the next couple of days... ...Accumulating snowfall is expected for the lee of the central Rockies and the central High Plains through Thursday, and across much of North Carolina, northern South Carolina and southern Virginia late Thursday into early Friday... Soils remain saturated across portions of the South from recent heavy rains with ongoing major to historic river flooding. While precipitation coverage and intensities are expected to decrease today across the South, another round of precipitation is expected to push eastward from the southern Plains tonight and move east across the Gulf Coast states and Southeast on Thursday. Additional moderate to heavy rainfall is expected across these areas, exacerbating the ongoing significant river flooding across areas of the South. Meanwhile, a broad region of Arctic high pressure pushing down across the north-central U.S. today will spread east-southeastward and encompass much of the central to eastern U.S. going through Thursday. This high will keep temperatures below average for this part of the country, with exception to central and south Florida where above average temperatures will persist through the balance of the week. Overall, the cold spell will be brief with temperatures beginning to rebound to above average levels by Friday across the northern Plains and Upper Midwest. This warming trend will then translate eastward this weekend across the Great Lakes and Northeast. In the short-term, the cold air filtering south will support accumulating snowfall through early Thursday from the lee of the central Rockies and over the central High Plains. Accumulating snow is also now likely late Thursday through early Friday from the southern Appalachians, eastward across much of North Carolina, northern South Carolina and southern Virginia where locally several inches of snow is expected. Elsewhere, dry weather will persist across much of western U.S. from the West Coast into the Great Basin and the northern Rockies. Temperatures are expected to be somewhat warmer than normal along the West Coast and into the Great Basin through Friday. However, there will be a weak area of low pressure coming into the Southwest by this weekend which will bring some clouds and showers along with temperatures trending below normal.
