Boston weather, metro north and west: Winter pattern continues into March

A snapshot look at the next three days. The theme, cold and even colder!
A snapshot look at the next three days. The theme, cold and even colder!

A weak disturbance moving through New England today with low pressure well out to sea south of us will not be much of a factor in our weather as far as precipitation goes. A slim chance of a few flurries or snow shower will be all to expect Wednesday. An icy cold night is in store for us tonight as many of you will have temperatures dropping into the single digits by morning.

Thursday starts off quite cold with some morning sunshine. Low pressure in the eastern Great Lakes Thursday morning moves quickly into northern New England by evening. The attendant cold front is expected to cross the area late in the day or evening and behind it comes even colder air for Friday. Scattered snow showers, perhaps a few snow squalls, will accompany the cold fronts arrival and passage during the afternoon and part of the overnight.

Friday marks the final day of what has been a colder than normal February. With that said we will close out the month with the coldest day of this week as temperatures run some 15 to near 20 degrees below normal for the day. Our average high for this time of year is about 41 in the Boston area. Lows at night will dip to 10 degrees or slightly lower throughout the area with frigid wind chills below zero.

Strong high pressure comes sweeping out of the Canadian Plains and into the US Plains expanding toward the East Coast during Friday. The high moves offshore Saturday as another weak disturbance approaches from the Great Lakes and may trigger a few more snow flurries or snow showers over the weekend. It pulls yet another cold front through here by Sunday morning with the frontal boundary stalling south of New England. Thereafter, low pressure slides through the lower Ohio Valley and stretches eastward to the coast south of New England by Monday, along the stalled frontal boundary. With cold air in place it is a fairly good bet that snow develops sometime later Sunday night or early Monday and could last well into the day. How much snow remains in doubt at this time.

Typically when March arrives, which it will do Saturday, one starts to think about winter winding down and some occasional spurts of spring weather by mid to late month. It certainly will not be the case at the beginning of the month as the cold weather pattern lasts into next week. One optimistic note, Daylight Savings Time will go into effect the second weekend of March making for sunsets after 6:30 p.m.

72 Hour Outlook:

Wednesday: Partly to mostly cloudy. Slight chance of a passing flurry or snow shower. Cold, high temperatures in the upper 20s. Gusty west winds in the afternoon.

Wednesday night: Mainly clear and colder. Lows 5 to 10 degrees. Gusty evening winds diminish to 5 to 15 mph later at night.

Thursday and Thursday night: Morning sun, followed by mostly cloudy skies. Chance of a snow shower or snow squall in the afternoon and early night. Partly cloudy thereafter. Cold and windy. Highs in the upper 20s with overnight lows around 10 degrees. Winds may gust 30 to 35 mph.

Friday: Windy and bitterly cold. Despite abundant sunshine high temperatures only in the low 20s.

Friday night: Bitter cold continues. Fair skies, lows again around 10 degrees to some single digits across the interior.
