The storm that is moving through New England this morning will wind down throughout the evening and overnight hours. Precipitation is already beginning to taper off in western New England. Drying out will continue from west to east until lingering snow showers end in eastern Maine early Thanksgiving morning.
Radar as of 10am:
The rain/snow line has advanced into central New England and will continue moving north during the day today. The Berkshires and Worcester Hills slightly overperformed on snowfall overnight, with up to 4 inches in Plainfield, Massachusetts. The Worcester Hills saw a general 2-3 inches, with the City of Worcester picking up 2.8 inches.
Wind gusts of 40-50mph have started along New England's coastline. This has led to some power outages in the region. As of 10am, about 10,000 are without power. A vast majority of these outages are near the coast, where the strongest winds are occurring.
The storm's exit will not usher in a significant air mass change, so temperatures will remain stable heading into Thanksgiving with most areas staying at or above freezing tonight. Temperatures on Thanksgiving will be mainly seasonable, with highs in the mid 30s to mid 40s in northern New England and the low 40s to about 50 in southern New England. The day will be generally calm and dry with a mix of clouds and sun. There will be a noticable breeze, so it will feel a bit chillier.
Beginning Friday morning, a cold front will drop into northern New England. This front will move southeastward through New England during the day on Friday. This front will bring a much colder air mass to New England, with the coldest temperatures of the season likely. The frontal passage will be mainly dry.
Weather map for Friday, showing the cold front dropping into New England:
Friday itself will be similar to Thursday, only a few degrees cooler as the front will stunt warming in the afternoon. The northern third of New England will see a much colder day as the front will prevent much of any daytime warming.
The cold front's full effect will be felt Friday night into Saturday. Overnight lows for Saturday morning will be in the teens to mid 20s with single digits possible across the northern third of the region and the higher terrain. There are some questions as to just how cold the coast gets, so places like Boston and Portland may stay a bit more mild Friday night to Saturday morning. A bit more mild in this case would be temperatures around the freezing mark instead of well below freezing.
GFS showing expected temperatures Saturday morning:
Regardless of how cold it gets near the coast Saturday morning, it will be cold everywhere for afternoon highs on Saturday. Temperatures will struggle to make it past the freezing mark with most of northern New England and the higher terrain of southern New England failing to make it to 32°. Areas of southern New England that do make it above freezing will remain in the 30s.
This cold air won't last too long as temperatures begin to rebound on Sunday and Monday. This will also be when the next system will likely move through New England. It will be a similar setup to the one happening today and could have similar precipitation with a rain/snow advancing north during the night Sunday into Monday. Right now, it doesn't look like precipitation will be as heavy as the storm happening today. This storm will likely occur Sunday night through Monday.
CMC showing potential weather overnight Sunday into Monday:
Into the middle part of next week, and possibly beyond, the temperatures will remain on the cooler side, with generally below average temperatures expected through early December, with some seasonable days mixed in.
