Late Week Nor'easter to Bring Snow to Some, Coastal Flooding to Others

An amazing day has unfolded for New England with abundant sunshine, muted at times through high-altitude clouds, and an active southwest breeze teaming to boost temperatures to near 60 degrees.

The exception will be in Northern Maine, where snow flies this evening and overnight with a few inches of accumulation, while the rest of us see a few evening sprinkles or a brief shower, then variable clouds and a fairly mild night with lows in the 40s and 30s. Clouds will increase Thursday but aside from light morning snow in Northern Maine, rain holds off until evening from late day in southwest Connecticut to late evening in Boston.

Rain will fall heavily at times Thursday night while expanding north and continue to fall throughout the day Friday. A transition to snow is the most uncertain part of the storm forecast, but we expect mountains to snow Friday morning, then the snow line drops to the valleys and heads south late day Friday into Friday night with highest accumulation in the higher terrain inland, where we’re conservatively estimating over 6 inches but amounts in mountains may be much higher.

TIMELINE: Tracking This Week's Nor'easter

At the coast, some snow is likely Friday night after a couple inches of rain with localized flooding, but the much bigger concern is the combination of locally damaging wind gusts over 60 mph Friday afternoon, coupled with a high tide that will bring moderate to major coastal flooding Friday 11 a.m., Friday night around midnight and Saturday at noon.

The weekend will be dismal with a continued onshore wind keeping clouds and light rain/snow around until brief improvement early next week ahead of the next storm around midweek in our exclusive Early Warning Weather 10-day forecast.
