Lake Effect Snow Continues, Snow For Appalachians And Warm Temperatures Out West

Despite the latest winter storm winding down, heavy lake effect snow continues downwind of the Great Lakes. This is especially true off Lakes Erie and Ontario, where blizzard warnings from snow, winds and cold temperatures persist in New York state. A clipper system may deliver light snow accumulations across the Ohio and Tennessee Valleys into the Appalachians. Temperatures will be warm out West.
