Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 151 PM EST Sun Nov 06 2016 Valid 00Z Mon Nov 07 2016 - 00Z Wed Nov 09 2016 ...Locally heavy rain possible across portions of the southern plains and Gulf Coast... ...Unseasonably warm temperatures expected to persist from the northern Rockies to the Upper Midwest... Moisture from the Gulf of Mexico along with an upper-level disturbance will continue to bring showers and thunderstorms to portions of the southern/central plains and western Gulf Coast tonight, spreading east into portions of the lower Mississippi valley by Monday afternoon and evening. Locally heavy rainfall is possible for these areas. Farther north, a relatively weak cold front will move east across the northern plains and Upper Midwest tonight into Monday. The front will move into the Ohio valley and lower Great Lakes on Tuesday. Scattered showers will be possible along ahead of the cold front as it passes through these areas. The cold front will have little affect on the unseasonably warm temperatures from the northern Rockies to the Upper Midwest. The Pacific air mass in the wake of the cold front will not be appreciably cooler than the air mass ahead of the front, and temperatures will remain above average. Afternoon high temperatures on Monday and Tuesday are forecast to be 10 to 25 degrees above average from the northern Rockies to the Upper Midwest. The western U.S. will remain predominantly dry through Tuesday. Rain showers are possible this evening across portions of coastal Washington, with scattered snow showers in the Cascades. Dry conditions should prevail on Monday, however, with the possibility for a few scattered showers remaining confined to the Olympic Peninsula. A frontal system will approach the region by late Tuesday, spreading rain into coastal Washington once again. Ryan Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
