A big 'ol late–season snow maker may be in store for the Midwest, Mid-Atlantic, Midwest and Northeast states. A messy weekend in the Midwest and the South is already apparent as wave after wave of energy drops in from the Rockies in the SE. Rain will be heavy for the Gulf Coast this weekend, but snow will develop over Colorado and stretch to Illinois Saturday morning. I'm thinking about 5 to 10 inches of snow is possible from Kansas to western Illinois.
That energy makes a bee line for the Atlantic Ocean Sunday. The energy will transfer in the water, and carve out a coastal storm by Monday morning. This nor’easter appears to be far enough out to see to draw in the cold air, making it a major snow maker from WV to New England through Tuesday. Keep in mind this is a transition season (winter to spring) so the models don’t handle storms like this very well this time of year. Still, it looks plausible to me for D.C., Baltimore, Philly and NYC to get at least a half foot of heavy, wet snow.
