Light to moderate snowfall will be possible on Tuesday from the Northeastern US into the Ohio River Valley as a surface low deepens off the coast of Virginia. Elevated winds and seas are possible across the Northern Gulf of Mexico as high pressure building into the Gulf of Mexico interacts with an area of low pressure over the eastern United States.

Total accumulations of 3-6 inches will be possible with locally higher accumulations in excess of 8 inches will be possible from Northeastern Massachusetts and northward across Coastal New Hampshire and Maine.
