Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 341 AM EST Fri Nov 28 2014 Valid 12Z Fri Nov 28 2014 - 12Z Sun Nov 30 2014 ***Cold on Friday for the eastern U.S. then warming*** ***Big cold front entering the northern Plains*** ***Pleasant weather continues for the southern tier states*** The eastern half of the U.S. will have colder than average temperatures to close out the week with an upper trough overhead and northerly winds. Widespread 30s and 40s are expected for daytime highs, and subfreezing lows. Some lake effect snow showers are also expected downwind of the Great Lakes. Warmer weather is forecast to arrive for the weekend as the cold surface high moves eastward and the wind becomes more southerly. Across the northern Rockies and northern Plains, an arctic front slowly sagging southward from Canada will bring much colder weather from Washington state to the Dakotas for this weekend. A sharp drop in temperatures is expected where this front passes through. There will also be widespread light to occasionally moderate snow with this front, but the greatest concentration of heavy snow should remain north of the Canadian border. Elsewhere across the continental U.S., nice weather will continue from the southwestern U.S. to the Deep South with mostly clear skies and dry conditions. Periods of rain are likely for northern California and Oregon with onshore flow and a cold front moving through the region. D.
