3-Day Outlook: Wednesday, Feb. 21-Friday, Feb. 23
High pressure drifts east of the Valley today with continued sunny skies and warmer temperatures as southerly air is drawn into the region on breezy south winds. Partly cloudy skies are expected tonight into Thursday with lows in the upper teens above zero overnight.
Partly sunny skies will overspread the Valley Thursday with increasing clouds Thursday night as a frontal system approaches from the west trailing from a low farther north in Canada. Snow is expected to develop Friday night an continue through Saturday, as a low tracks offshore from the Mid-Atlantic.
With regard to potential snowfall, the National Weather Service in Caribou notes that “anything more than advisory level snowfall [= 4 inches averaged over a forecast zone in 12 hours] would be an outlier solution at this time, and as of now have about 2 to 3 inches of snow for the Friday night period with highest amounts inland and across the eastern zones.”
The Mid-Atlantic low lifts towards Nova Scotia Friday night. Currently, the bulk of this system’s impact looks to remain over New Brunswick, with some precipitation in eastern portions of Maine. Snow continues Friday night into early Saturday.
