Greater Boston, North Shore and Metro West: High pressure will slide offshore today turning winds to the southwest. A warm front extending into New York State pushes northward into Canada overnight. The general idea will be for a milder trend on Sunday, after another below normal cold day on Saturday, despite plenty of sunshine.
It was a very chilly Saturday morning with temperatures in the teens for most and low 20s along some coastal locations. Average high temperatures for the end of November are in the upper 40s in the Boston area but we can expect our highs today only in the low to mid 30s across the area, meaning we are running about 12 degrees or so below our normal highs.
Clouds fill in the sky tonight as the warm front lifts northward. There is a slight chance that far interior sections may see a snow flurry, sprinkle or sleet pellet late tonight. Temperatures remain near steady and then climb well into the 30s to near 40 degrees after midnight.
Sunday begins with considerable cloudiness in the morning but the sun breaks through with a partly cloudy afternoon. Milder air flows in on a brisk southerly wind and this will help drive afternoon temperatures well into the 40s with a few low 50s possible.
Partly cloudy skies overnight and mild. Lows only in the 40s with a brisk south to southwest wind.
The new work week and month of December starts off mild but a cold front lurking to our west will change all of that by Tuesday morning. Enjoy your Monday with highs into the low 50s because once the front passes through temperatures are going to plummet back into the 20s later Monday night and only recover into the 30s on Tuesday as skies remain generally partly cloudy through this timeframe. There is a remote chance of a sprinkle when the front passes through late Monday and Monday evening but the front will be moisture starved, meaning a dry frontal passage is more likely than not.
The seesaw temperatures continue mid week as temperatures climb back well into the 40s Wednesday but with a chance of an early snow shower or afternoon rain shower as another warm front passes through to our north.
It turns cooler once again on Thursday and Friday with generally fair skies both days. Highs about 40 degrees.
As we close out the month of November this weekend a quick look at the temperatures tell us that we will end the month about 2.3 degrees below normal in Boston. Precipitation is about 1.5 inches above normal.
