Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 426 PM EDT Sun Mar 29 2015 Valid 00Z Mon Mar 30 2015 - 00Z Wed Apr 1 2015 ***Moderating temperatures across the eastern U.S.*** ***Scattered showers from the Great Lakes to Deep South*** ***Rain and mountain snow returning to the Pacific Northwest*** After a very cold start to the day on Sunday across much of the eastern U.S., temperatures are beginning a well-advertised warming trend as we head into the beginning of the work week. The surface high will emerge over the western Atlantic Ocean, allowing for winds to become more southerly from the Gulf of Mexico to the Ohio Valley. High temperatures are expected to return to the 50s and 60s for many areas by Monday. A weak cold front will be crossing the Midwest states and reaching the East Coast Monday afternoon along with a shortwave trough aloft. This will likely bring some scattered showers from the Deep South to the Ohio Valley and Mid-Atlantic, and most of this activity should be light. Some late-season snow is expected across the northern Great Lakes and over parts of New England with marginally cold temperatures. The temperature change behind this front will be small compared to the last cold front. A cold front approaching the Pacific Northwest will bring scattered showers and mountain snow back into the forecast for late Monday and into Tuesday. The heaviest precipitation is likely to occur just north of the border into southern British Columbia. Unfortunately, areas to the south in California and Nevada are expected to remain dry where the severe drought is ongoing. D.
