Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 358 PM EST Fri Jan 23 2015 Valid 00Z Sat Jan 24 2015 - 00Z Mon Jan 26 2015 ...Storm tracking up the Eastern Seaboard will bring heavy rains into the Mid-Atlantic coast and a swath accumulating snows from the central Appalachians to southern New England... ...Quick-moving clipper system will streak snow across the Upper Midwest this weekend... ...Wet conditions will continue in the extreme northwestern corner of the Nation... An area of low pressure spinning in the northern Gulf of Mexico will steadily lift through the Southeast Friday night...before rapidly deepening while tracking up the Eastern Seaboard on Saturday. An abundance of Gulf and Atlantic moisture being pulled into the strengthening storm will fuel widespread precipitation across the eastern third of the Nation. Heavy rains and thunderstorms are expected over the Southeast and southern Mid-Atlantic states...and a swath of accumulating snow is expected from the central Appalachians to southern New England. Marginal temperatures surrounding the I-95 corridor will lead to a messy transition zone of sleet and freezing rain between the heavy rain and snow. Light snows will be possible with a cold front sweeping from the Upper Great Lakes to interior New England on Saturday. Upstream...a clipper system dropping down from Canada will streak snows across the Upper Midwest while it slides from the northern Plains to the Middle Mississippi Valley Saturday into Sunday. A series of Pacific systems moving inland will keep conditions wet across the extreme northwestern corner of the Nation Friday night. Above normal temperatures in the Northwest will limit any snow potential...but a ripe slug of moisture streaming onshore should lead to heavy rains along the upslope side of the Olympics and Cascades. Precipitation should come to an end on Sunday as ridging builds in aloft. Gerhardt Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
