Forecast Discussion

Low pressure will gradually move east of the area today, with moisture from an upper level disturbance and a strengthening upslope flow keeping the higher summits firmly in the clouds w/ snow showers. Snow showers will become more numerous this afternoon as the upper level disturbance moves closer to New England, with temperatures continue to fall through the day in the wake of the cold front from yesterday. Overnight the pressure gradient will increase as low pressure in the Gulf of Maine strengthens, with winds ramping up quickly during the evening hours to near hurricane force, with gusts possibly exceeding 100 mph near sunrise. Snow showers will begin winding down during the morning hours Thursday, with winds slowly decreasing as high pressure begins building in from the west. Snow accumulations across the higher summits through Thursday morning will range 1-3 inches.
