Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 209 PM EST Tue Nov 03 2020 Valid 00Z Wed Nov 04 2020 - 00Z Fri Nov 06 2020 ...One more day of cold in the Northeast before above normal temperatures encompass the entire United States... ...Quiet weather pattern continues with notable precipitation limited to the Northwest... In the wake of a powerful cyclone and trailing weak clipper system, much of the Northeast will experience chilly temperatures and blustery winds through Wednesday. Meanwhile, very warm weather will continue to dominate the west and surge eastward into the northern Plains and Great Lakes through Thursday evening. Potential record breaking warmth will extend across much of the Northern Plains and Rockies Wednesday and Thursday, with temperatures about 15 to 30 degrees above normal. Record high temperatures are also possible across the Southwest through Thursday, with highs in the 80s and 90s. This warm pattern is driven by a large and anomalous upper-level ridge centered across the north-central United States. This ridge is forecast to move eastward and weaken across the Northwest, thanks to a very active Northern Pacific moisture stream that will slowly progress southward into Washington and Oregon. A parade of weak cold fronts will bring the potential for rainfall, as each wave chips away the ridge. It will be a slow process and rainfall will remain limited to Western Washington and Northwest Oregon through Thursday morning. Rainfall chances will finally increase across the northern Rockies Thursday evening as a more powerful cold front swings through. While not a respite for the heat and the drought across the Southwest, this is a hopeful sign for a significant change in pattern toward the end of the week and into the weekend.
