November 18th Update
Major weather changes are on the way for this weekend. The relatively mild stretch will be replaced by a big chill that lasts into the middle of next week. Thanksgiving may be showery and some rain cannot be ruled out on Black Friday. The overall pattern looks much cooler than what we’ve seen for most of this month.
Saturday looks mostly cloudy and potentially damp (especially in E MA) as a storm in the Atlantic Ocean takes a swipe at Southeastern New England. Highs will be near normal in the low 50s with a northerly breeze. A strong cold front sweeps through New England late Saturday night. A line of showers is likely after midnight and before dawn. The showers will likely not bring more than 0.1-0.25″ rain, but they be accompanied by 25-35 mph wind gusts.
Much colder weather rides in on strong west-northwest wind on Sunday. The early-morning high temperature will be in the upper 40s to low 50s, with the temperature falling through the 40s into the 30s by late in the day. It will be a mostly cloudy day. Wind gusts over 30 mph are possible.
Monday looks windy and cold, with highs in the upper 30s to low 40s. Passing snow showers or flurries are possible. I do not expect any accumulating snow. It will stay breezy to windy and chilly into Tuesday. The snow shower/flurry threat diminishes Monday night. Look for partly cloudy skies on Tuesday, but it will be cool with highs in the low 40s. Overnight lows will be in the upper 20s to low 30s Sunday night through Wednesday night.
Wednesday stays cool, but it will be a lot less windy. Expect clouds to stream in from the west. Highs will be in the low to mid 40s with dry skies likely through the evening. Clouds will be stubborn on Thanksgiving, and showers are possible in the afternoon and at night. Highs will be in the 40s.
The early outlook for Black Friday is for plenty of clouds with showers possible. It’s a long way out, and we’ll fine-tune the forecast.
Looking ahead to December, the long-range models are showing a colder weather pattern for most of the United States. Most of our recent winters have not featured much snow in December, but this year’s pattern suggests that winter could get off to a faster start in the Northeast. The same models that are showing a colder pattern also depict near-normal precipitation in the Northeast through the end of the year. That’s good news because this year has been very dry in parts of Southern New England. The bottom-line is the weather could be playing a bigger role in your everyday life in the next month and half.
