Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 305 AM EST Mon Nov 06 2023 Valid 12Z Mon Nov 06 2023 - 12Z Wed Nov 08 2023 ...More unsettled weather expected to bring beneficial precipitation across the Pacific Northwest and the Northern Rockies over the next couple of days... ...Mixed light rain and snow will brush the northern borders of the Northern Plains to the interior Northeast... ...Fair and mild weather expected to continue from the southwestern U.S. to much of the eastern U.S; cool Pacific air arrives over the West today.... Troughing in the West will continue to generate rainfall across much of the Northwest over the next couple of days. Some instability mixing in with a plume of moisture along the immediate Pacific Northwest coast will support a Marginal Risk of Flash Flooding. The primary areas of concern are Burn Scars and other vulnerable surfaces around the Washington--Oregon coastal border region. Light to moderate snow will fall over the highest elevations of the Cascades and Northern Rockies today before the snow level drops behind the upper trough on Tuesday. Shortwave energy moving across the Upper Midwest and Great Lakes will continue producing rain/snow showers across those areas today before spreading into the Northeast tonight and into Tuesday. Diffluence aloft associated with the western trough will bring another round of mixed precipitation to the Upper Midwest/Great Lakes Tuesday night. Ridging across the South/Southeast U.S. will allow high temperatures to soar into the upper 70s to low 90s over the next couple of days. Many places from the Southern High Plains to the Southeast will experience record high temperatures today and Tuesday. Highs over the Central/Southern Plains will be between 20-30 degrees above average during this period. Elsewhere, the western trough will bring a cool Pacific airmass and below average temperatures to much of the West beginning today.
