November 21st Update
The weather pattern has flipped from unusually mild to on the cool side for Southeastern New England. Windy and chilly weather lasts through the early part of the week. There will be passing clouds, but it looks mainly or all dry through Wednesday. A weak system will bring light rain/snow showers on Thanksgiving morning. It stays very cool through the holiday.
Expect partly to mostly cloudy skies with wind gusts over 30 mph on Monday. Highs will be near 40. It will be in the upper 20s to low 30s Monday night as the wind stays active.
Tuesday looks brighter, but still gusty and relatively cold. Highs will be in the low to mid 40s with partly to mostly sunny skies. The wind will relax Tuesday night into Wednesday. It will be a cold night, with lows in the 20s. Wednesday looks ok, but still a bit cool, with highs in the low to mid 40s.
Clouds increase Wednesday night, and light snow or flurries may arrive by dawn on Thursday. The storm system coming through on Friday will not have much moisture to work with, but a period of light snow with temps in the 30s is possible through midday. It will gradually get a bit milder, and any snow will most likely change to drizzle or light rain showers Thursday night. Again, it does not look like there will be steady or heavy precipitation. At this point, the best chance of coating of snow is inland and early on Thanksgiving.
Black Friday will be dry or mainly dry, with lows in the 30s, and highs in the 40s. There will be a lot of clouds around. Another storm system arrives late Friday with chilly rain showers likely Friday night into Saturday morning. The track and intensity of this storm is important because it will help to decide the type of precipitation. Right now, it looks like mainly or all rain.
Showers wind down on Saturday afternoon with highs in the 40s. Do not expect a big warm-up late in the weekend. Sunday looks dry, but cool, with highs in the mid 40s again.
