The mesoscale models (HRRR and NAM 3KM) seem to the in agreement on the evolution of the storm coming tonight and Saturday. The storm comes through the Carolina’s then off the coast Saturday morning where it will intensify heading northeast out to sea. The strongest part of the storm will be when is passes south of New England so the heaviest snows will occur across southern New England. Light snow should develop tonight and spread northeast from western Maryland through Pennsylvania into New England.
The snowfall will be a general 1-4 inches with 4-8 inches across southern New England. Boston should see 3 inches while Providence will see 6 inches. Major I-95 cities will miss out on this storm but the storm will help to bring fresh cold air in and push the prospects for snow in the big cities Sunday.
