The winter storm that brought heavy snow and blizzard conditions to portions of the northern plains and Upper Midwest will continue to rapidly wind down late this afternoon and into the early evening hours. Lake effect snow showers will persist downwind of Lake Superior and Lake Michigan through tonight and Tuesday in the wake of the low pressure system. As the surface low associated with this system moves into Ontario and Quebec, the cold front will sweep eastward tonight from the Ohio valley to the eastern U.S. A mix of wintry precipitation including snow, sleet, and freezing rain is expected tonight across portions of northern New England. Farther south, rain and a few thunderstorms are possible along and ahead of the cold front from the Ohio valley to the lower Mississippi valley and the Southeast tonight and Tuesday. A frontal system will move into the Pacific Northwest this evening, spreading rain and mountain snow from the coast across the Cascades and into the northern Intermountain West. Onshore flow will continue on Tuesday as the cold front moves inland, with rain and snow ongoing across the Northwest into Tuesday night. Heavy snow is possible across the Cascades as well as the higher terrain of the northern Intermountain West. Temperatures will be above average across most of the central and eastern U.S. on Tuesday. The East Coast will be particularly warm, with afternoon high temperatures forecast to be 10 to 25 degrees above average. On Wednesday the most anomalous warmth will shift west to the southern and central plains, where high temperatures will rise into the 10 to 20 degrees above average range.
