Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 304 PM EST Thu Nov 27 2014 Valid 00Z Fri Nov 28 2014 - 00Z Sun Nov 30 2014 ...Stormy weather for the Pacific Northwest and Intermountain West... ...Snow expected in the Upper Midwest and Great Lakes.. ...Cold weather for the northern tier states... Snow showers continue to fall across the Ohio Valley and into the Northeast as the nor'easter moves further east into the Atlantic. Snow can still be expected in the Mid-West, Great Lakes, and northern Appalachians regions through the remainder of Thanksgiving night. In addition, colder than normal temperatures will persist for the the eastern half of the country through the first half of the weekend. There is quite the impressive frontal system moving through the Pacific Northwest and the Intermountain West. This boundary will slowly make its way south, and behind it very cold Arctic air will follow. Higher elevation snow and moderate rainfall can be expected throughout these regions along with strong winds. Currently, the precipitation is mostly light to moderate along the Cascades. However, by Friday and into Saturday it will become more widespread across the Intermountain West and into the northern Plains. By Friday night, the heavier snow amounts will begin to approach the northern Rockies in Idaho and northwest Montana. On Saturday, as the Arctic front dips across the northern Plains, the heavier snowfall will begin to advance across northern Montana and into North Dakota. Snow begins to move into the Upper Midwest by late Thanksgiving night and Friday morning. There is already lake effect snow on the lee side of the lakes. However once the surface boundary associated with the Pacific Northwest system begins approaching the Upper Midwest, snow will be more widespread. By Saturday, snow will begin to taper off in this region and will be confined to the Upper Great Lakes. Cold weather will continue for the northern Plains and Upper Midwest as a Canadian surface high governs the weather pattern. Quiet weather is expected from the Southwest through the Gulf Coast during the short term period. Fanning Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
