Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 PM EDT Tue Jun 16 2020 Valid 00Z Wed Jun 17 2020 - 00Z Fri Jun 19 2020 ...Cool and wet weather continues over the Mid-Atlantic and the Carolinas... ...Cool and rainy weather in the Pacific Northwest will move into northern Rockies as another round of late-season high-elevation snowfall... ...Hot conditions through the central and northern Plains; severe storms in the northern Plains; fire weather danger in the Southwest and central High Plains... A slow-moving upper-level low will continue to bring at least a couple more days of cool and wet weather for the Mid-Atlantic region and down into the Carolinas. Up to a couple of inches of additional rain can be expected for parts of Virginia and North Carolina where flash flooding remains a possibility into Wednesday morning. The upper low will gradually weaken with time and the threat of heavy across the Mid-Atlantic will slowly ease on Wednesday. However, scattered areas of rain and a few thunderstorms can be expected to edge further north and west toward the northern Mid-Atlantic, central Appalachians, and the lower Great Lakes Wednesday night into early Thursday. The northwestern U.S. will also witness cool and damp weather courtesy of a large cool air mass associated with yet another anomalous upper low. Some of the highest elevations of the northern Rockies can expect to receive accumulating snow, particularly for central Idaho into northwest Wyoming tonight into Wednesday where winter storm watches and warnings remain in effect. While seasonally cool temperatures look to stick around in the northern Rockies, the Pacific Northwest along with northern and central California should see temperatures rebound more seasonal levels on Wednesday, and then above normal by the second half of the week. Elsewhere across the Lower 48, the Great Plains and Upper Midwest will be in the warm sector ahead of an approaching cold front over the Rockies, resulting in widespread high temperatures into 90s. Some severe weather is also possible across the Dakotas into northern Minnesota through Wednesday as the front slowly progresses eastward. To the Southwest, elevated to critical fire weather conditions, thanks to prolonged breezy and very dry conditions. Red Flag warnings remain in effect from Nevada to the high plains of eastern Colorado and western Kansas. Kong/Mullinax Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
