A major nor'easter is slamming Southern New England. Although most of us will be off the roads - and catching some zzs - as the brunt of the storm hits, it still could cause damaging wind gusts and scattered power outages, not to mention urban flooding and heavy runoff.
Gusts have already topped 50 miles per hour in isolated spots on Cape Ann (Rockport) and more is to come. Needless to say, with the persistent wind over the course of several hours, there could be power outages and downed trees in the middle of the night. This also acts to pile water along the coast as well, so we are expecting some minor to moderate coastal flooding at the 8am high tide tomorrow. For that reason, a Coastal Flood Warning is up for those areas.
Precipitation is another matter. We aren't drawing a distinct rain/snow/ice line with this storm. Instead, the line is blurred and changeable. We could see all three present at once through the course of the night north and west of Boston toward Rt. 128. It's well known that during these intense storms, the cold can be mixed into the storm from the middle and lower atmosphere.
Both the precipitation and the strong wind will slowly unwind Tuesday morning as the storm begins to move overhead between 8-10 a.m. There's another round of rain that sweeps through to signal an end to the storm, but that won't finish until almost noon. Leftover drizzle and mist will finish the day.
No cold behind the storm, so expect highs to near 50 on Wednesday as we settle out the work week and wait for the colder air into the weekend.
