Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 332 PM EST Sun Jan 11 2015 Valid 00Z Mon Jan 12 2015 - 00Z Wed Jan 14 2015 ...Freezing rain expected to spread through parts of the Midwest and northern Mid-Atlantic tonight... ...Another blast of cold temperatures will spread southeastward through much of the Plains, Midwest and Northeast Monday/Tuesday... ...Western storm system to bring moderate to heavy snow to the Four Corners states... There will be two main weather systems to impact the lower 48 early this week, one in the East and one in the West. A snow and ice storm will continue to move northeastward from the Mid-Mississippi Valley tonight and on Monday, bringing a swath of freezing rain from near St. Louis to southern New England. Storm total ice accumulations should generally be less than 0.25 inches with most locations receiving less than 1/10th of an inch. To the north, a stripe of light to locally moderate snow should impact locations from the Midwest into central and northern New England. Farther south where temperatures will be too warm for frozen precipitation, steady rain and even some thunderstorms are expected for the Carolinas. The storm system will make for poor driving conditions through much of the day on Monday, followed by much colder temperatures in its wake, as a cold front associated with the storm sinks into the western Gulf of Mexico and clears much of the East Coast. High temperatures behind the winter storm will drop about 20 degrees compared to today in the southern and central High Plains, and similarly for New England for Tuesday. Across the West, an upper level disturbance will enter the northwestern U.S. tonight and track into the Four Corners region on Tuesday. Upper level ridging behind this system will temporarily build over the West Coast, giving the coastline a break from recent unsettled conditions. The heaviest snow with the upper level disturbance will develop Monday night into Utah's Wasatch range and the favored higher elevations of southwestern Colorado where roughly 6 to 12 inches could fall by late Tuesday.
