Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 213 PM EST Mon Jan 12 2015 Valid 00Z Tue Jan 13 2015 - 00Z Thu Jan 15 2015 ***Unsettled weather along the East Coast*** ***More bitterly cold weather for the north-central U.S.*** ***Snow for the Intermountain West and Rockies*** The multi-faceted frontal boundary stretched across the East Coast states is bringing snow for interior New England, and a wintry mix of sleet, freezing rain, and rain farther to the south across Pennsylvania and southern New England. Residents of the Mid-Atlantic and Southeast U.S. will have a cold rain to deal with before the cold front clears the region. Although the northern portion of the front will be progressive, the southern end will be slow to exit and another wave of low pressure is expected to develop offshore on Wednesday. There should be enough moisture and cold air in place to support light snow and a wintry mix across much of North Carolina and Virginia Tuesday night and Wednesday morning. Behind the cold front, a large surface high from Canada will bring another round of bitterly cold temperatures from the Upper Midwest to the Ohio Valley and Great Lakes, with widespread highs in the 10s and subzero lows for Tuesday and Wednesday. By the end of this forecast period, a significant warming trend is forecast for the central and eastern U.S. east of the Rockies as a pattern change evolves. High temperatures by the end of the week will return close to seasonal averages or perhaps slightly above average. Out West, an upper level trough and surface low will result in numerous snow showers for interior parts of the West, including the Four-Corners region, Great Basin, and the central and southern Rockies. The greatest accumulations are expected for the high elevation mountain ranges, and a mix of rain and snow showers for the lower elevations of Arizona and New Mexico. D.
