Winter storm moves from the southern Plains today to the Great Lakes on Sunday and then out to sea potentially by Monday morning. This will be a favorable track for significant snow accumulations for southern SD, much of NE, southern MN, northern IA, and western WI with a lot of these areas potentially getting snow in the 6-14 inch range before it ends. The severe storm threat from this shift moves east into the southeastern states today and lingers into the Carolinas, southern GA, and northern FL. The Mid Atlantic and New England will mainly be rain with a brief changeover to snow for a time in northern New England resulting in a couple inches of accumulation by Monday morning.

More scattered snow and rain showers in parts of the west over the weekend with more accumulating snows in the mountain ranges with the heaviest coming in the Sierra Nevada and Cascades.
