Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 253 PM EST Mon Jan 29 2018 Valid 00Z Tue Jan 30 2018 - 00Z Thu Feb 01 2018 ...Colder weather returning to the eastern U.S. and more mountain snow for the northwestern states... A developing surface low off the East Coast Monday night and Tuesday is expected to bring a round of light to moderate snow to coastal sections of New England. An upper level disturbance behind it tracking across the Appalachians should also result in some light snow across portions of the Mid-Atlantic region and into upstate New York through midday Tuesday. Much colder weather returns to the East Coast region for the middle of the week behind the strong cold front with Canadian high pressure building into the area. Winter weather will also be making headlines for the Pacific Northwest and the northern Rockies through Wednesday, courtesy of an upper level trough, onshore flow, and a cold front moving through the region. The Cascades of Washington are likely to get the highest snowfall totals, which could easily exceed 18 inches above pass level. Up to an inch of rainfall is expected for the lower elevations. The warmest temperatures across the nation are expected for the western High Plains from western Kansas to western Texas, and also for the Desert Southwest with highs well into the 70s and low 80s. Mild weather is also expected to continue for the Florida peninsula. The next surge of arctic air arrives on Wednesday across the northern tier states with highs back below 20 degrees for parts of North Dakota and Minnesota. D.
