Cold Wind Blows This Weekend
Early fog and spotty black ice for early shoppers with low visibility across many low lying areas in central and southern New England. Morning fog will be lifting giving way to sunshine. Clouds may linger a little longer in Southeast MA and the Cape today. Winds are light with winds shifting to the south ahead of an approaching cold front. Sunshine and southerly winds will pump temps back into the mid 50’s this afternoon. Winds could gust up to 20 mph later today as high clouds will be increasing.
The cold front is on the move through New England tonight with cloudy skies and a brief shower or two especially after midnight. There may even be a stray snow shower across the north. This front is off the coast by 7AM Saturday. Early clouds will give way to increasing sunshine with a few fair weather clouds dotting the sky. Breezy West winds will shift in behind the front and gust towards 30 mph. Highs will try to climb into the mid 40’s by noon time, then temps will fall into the lwr 40’s by afternoon with colder air on the move.
The cold air will settle in over the region Saturday night and Sunday. Lows will be in the teens and 20’s Saturday night with clear skies. A steady light breeze should prevent a frost. Sunday will be the coldest day of the weekend. West breezes continue with highs struggling to get over 40 degrees. A few lower 40’s will be found in Southeast MA with 30’s for highs in the N & W. The good news is there should be plenty of sunshine to enjoy through the weekend. The bad news is it is a low sun angle this time of year, so prepare for a definite chill. Any gust of wind will make temps feel like they are in the 30’s
Winds will begin slacken Monday with a weakening gradient. High pressure to the SW of New England will provide enough sinking air to squeeze out another sunny day, but temps will still remain cool in the Lwr-mid 40’s. the lighter wind will make it feel more comfortable.
Looking ahead to our next weathermaker, there is still plenty of uncertainty in the long range of Tuesday & Wednesday. Every model run is providing a different solution and the trend continues. I really do not believe in anything I see at this point, yet my job is to provide you with some insight on what to expect.
It is all very track dependent. Cold air will be pressing south and forming a boundary as it clashes in with the mild air in the southern states. An area of low pressure will form along this boundary near Oklahoma and track towards or just south of the Ohio Valley. Here is where it gets interesting. A Low tracking west of us or right over us.. will mean a mix to rain solution, or a low tracking south of us will give more of a wintry mix. Ensembles continue to provide a variety of tracks. The Euro has a non-event with the cold pushing the energy south of us that we stay dry. Yet the latest GFS has the low just south of us providing a mix of rain in the south and snow in the north…with a change to snow for most as the storm pulls away. This further north track has more model support, yet we never like to completely rule out the Euro…but right now it is on an island by itself. We will have to see if other models start jumping ship to join the Euro…or if the Euro will go back t0 its former position of a low tracking just south of us. Either way, it is a fast moving batch of precip, which should not have a very big impact. That said, a few inches of snow is nothing to sneeze at. Best chance of that will be north of the Pike…but again…all speculations at this point.
There are no signs of any warmth like we are having this Friday in the near future. So make the best of it today! In fact, this December holds real promise for turning much colder and snowy as the NAO is about to go into the tank. This will make for a colder and stormier pattern in the Northeast. If trough continue to hit east Asia…that could spell more action for snow lovers!
