March comes in like a lion for the majority of the country with 3 separate systems affecting the country through the weekend.
First system moves from the southeast today through the Mid Atlantic tonight and then passes south of the coast of New England early Saturday. This system will produce mainly rain and even a few storms however on the northern fringes from southern PA to southern New England mixed precipitation or snow develops tonight and continues into early Saturday with some snow accumulation potential for cities such as Philadelphia, New York City, and Boston.
The second system moves from the Northern Plains to the Great Lakes region tonight and then weakens heading into the northeast on Saturday. Snow accumulations will range from 1 to 5 inches mainly with the higher totals expected from eastern SD through southern and central MN and into north central WI.
Finally the third system begins to organize in California today then tracks through the southwest and southern Plains Saturday to the southeast and Mid Atlantic Sunday and ending up around the New England coast by Monday morning. Widespread rain showers and a few storms are expected across the south into the Mid Atlantic through the weekend with a few severe storms possible in the southeast Sunday. Widespread accumulating snows are expected from the Wasatch Mountains in UT eastward through the central Rockies, central Plains on Saturday and Saturday night, and then Ohio River Valley to the northeast Sunday and Sunday night.
