Spring snow for the northeast

Heavy rains and snow are expected for the northeast through Thursday as a powerful trough moves up the coast. Flooding will be possible as heavy rains and warm temperatures will impact the region before the precipitation turns to snow overnight through Thursday.

Winter warnings have been issued in anticipation of snow which is expected to arrive late Wednesday evening to Thursday. Much of upstate New York is expected to receive 5-10 inches of snow, with higher totals possible. The highest accumulations are currently expected between the Adirondacks and the I-81 corridor across the border with Pennsylvania.

Winter weather advisories are also in place for the mountains of West Virginia, as 2-4 inches of snow will be possible overnight Wednesday through Thursday morning.

Rain is expected to move through the Ohio River Valley on Wednesday. This will lead to ripple rain showers and the risk of flooding due to the current state of saturated soils in some places.

There could be between 1 ″ -3 ″ of rain and normally this would not create a threat of sudden flooding, but since there is already so much water in the soils, the risk is higher even with a rapid downpour. . The greatest flood risk will be concentrated in the Deep South, but an isolated flood risk will cover much of the Carolinas, Virginia, and northeastern coastal areas.

The rain could also lead to rapid melting of snow on the ground and ice jams. Flood watches are in effect in northern Maine for this potential.

By Wednesday evening, the arctic air behind the front will produce a change in precipitation type. Moderate to heavy rains will develop into snow over northern New York State and much of northern New England, with heavy accumulations possible in places.

Higher elevation locations are likely to have the most snowfall accumulations, with some totals exceeding 6 to 8 inches. Some valleys in New York and Pennsylvania could also have moderate to heavy snowfall.

The heaviest snowfall is likely to occur between around midnight and noon Thursday, although lighter flurries may persist until Friday for some.
