Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 321 PM EST Sun Nov 17 2013 Valid 00Z Mon Nov 18 2013 - 00Z Wed Nov 20 2013 ...Severe weather possible for the Mid-Atlantic and the Northeast ahead of the frontal boundary... ...Strong and gusty winds expected across the Great Lakes and Northeast on Monday... ...Organized precipitation moves onshore in the Pacific Northwest by Monday... Widespread showers and thunderstorms will continue to breakout tonight and into the early morning hours of Monday ahead of the cold front currently pushing through the Mid-West. The Storm Prediction Center has noted that a few of the storms overnight across the Mid-Atlantic and Northeast could be strong and/or severe, but a widespread severe weather outbreak is not expected like we saw this afternoon across the Ohio Valley. The cold front is expected to push off the Mid-Atlantic coastline by Monday morning and surface high pressure will move in bringing clear skies and pleasant weather back to most of the eastern half of the nation. As the fairly deep surface low attached to the aforementioned front moves northeast into Canada overnight tonight, a strong pressure gradient will set up across the Great Lakes and the Northeast bringing strong and gusty winds to these areas on Monday. Additionally, moisture being wrapped around the low combined with westerly winds behind the front could bring a few light to scattered lake effect rain/snow showers to parts of both the Upper and Lower lake regions. Meanwhile, out west, persistent onshore flow off the Eastern Pacific will continue to fuel light and scattered rain and higher elevation snow over the Pacific Northwest and Northern Rockies. By Monday morning, a system approaching the coast will stream more steady and heavy precipitation into coastal Washington and Oregon and should spread to the Northern Rockies by the afternoon hours. Some minor accumulation of snow in the higher terrain is possible later in the forecast period. Monarski Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
