Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 234 PM EST Sun Jan 29 2017 Valid 00Z Mon Jan 30 2017 - 00Z Wed Feb 01 2017 ...Snow possible from the Upper Midwest and Great Lakes to the Appalachians and Mid-Atlantic... ...High winds possible for portions of the northern plains... A series of upper-level troughs will bring snow to areas from the Upper Midwest to the Mid-Atlantic and Northeast through Monday. The first upper-level trough will move from the Ohio valley toward the Mid-Atlantic coast tonight, sparking the development of a low pressure system along the Mid-Atlantic coast. A broad area of snow showers is occurring this afternoon across the Great Lakes as well as portions of the Ohio and Tennessee valleys. Snow will begin to spread east across the Appalachians and into the Mid-Atlantic tonight. As the new system begins to organize across the Mid-Atlantic region, a band of moderate snowfall is possible across portions of the Delmarva and southern New Jersey. Snow will come to an end across the Mid-Atlantic Monday morning as the low pressure system pulls away into the Atlantic Ocean. A second fast-moving low pressure system will develop across the northern plains early Monday in response to a vigorous upper-level disturbance. An area of snow will develop in association with this system Monday morning across the Upper Midwest, which will then spread east across the Upper Great Lakes through the day Monday. Additionally, high wind gusts in excess of 60 mph are possible across the northern plains on Monday in the wake of this system. By Monday night into Tuesday, snow associated with this second system is expected to spread into the Lower Great Lakes as well as the Northeast and northern Mid-Atlantic. Most of the western U.S. will remain dry through the short range as high pressure remains overhead. Late Monday into Tuesday, an upper-level disturbance will move into the Northwest bringing scattered areas of snow, and coastal rain. A colder air mass moving into the northern plains will strengthen a frontal zone across the northern High Plains and northern Rockies, which could serve to enhance snowfall across these areas by Tuesday. Temperatures on Monday will be 5 to 15 degrees below average across much of the eastern U.S., but will warm to slightly above average for most areas by Tuesday. Meanwhile, the central U.S. will remain warmer than average through the short range, with temperatures 10 to 20 degrees above normal.
