DAYS 1-5 (DECEMBER 25-29)
There is lots going on in the weather department but I’ll make this as short as possible. First the storm system we’ve been watching is moving through now and it appears it is behaving about as outlined in yesterday’s blog post. Low pressure is about to explode in the waters just east of here but move rapidly northeastward, pulling the snow (rain to the southeast) away with it, but not before a final burst of snow occurs from northern RI through eastern MA and south central and southeastern NH. It looks like the southern extent of this burst should be near the Cape Cod Canal with the rain/snow line from near northern Narragansett Bay to about Plymouth MA where areas near there that have not seen snow may get coated at the end. This will also be true for the tip of Cape Ann MA which also had a longer rain period. Where the heaviest burst of snow occurs, an additional 1/2 to 1 1/2 inch will occur along with a risk of a clap of thunder, bringing the accumulations mostly into the expected ranges across the region. So what this means is white Christmas for most of the region except the far southeast (Cape Cod). Once the storm pulls away it will be about the wind this afternoon. There are no big changes to the outlook going forward. A cold day is expected Tuesday with a passing snow shower as a reinforcing cold front arrives later in the day, and then the very cold air arrives for the middle of the week and into Friday as well. By late Friday we may be watching to see if a snow threat materializes for the region. It is too early to know the track and intensity of that system as far as how it will impact this area but will be watching.
TODAY – CHRISTMAS DAY: Snow (rain southeast) ends by late morning. Partial clearing this afternoon. Temperatures ranging widely from as low as the lower 20s central MA to the middle 40s southeastern MA will remain steady or slightly rise in the coldest areas and fall more rapidly in the warmest areas during the day. Wind becoming NW and increasing to 15-30 MPH interior and 25-40 MPH coast especially Cape Cod with higher gusts.
TONIGHT: Clear. Lows 10-18. Wind NW 10-20 MPH, higher gusts. Wind chill near 0 at times.
TUESDAY: Partly cloudy. Isolated afternoon snow showers. Highs 20-28. Wind W 10-20 MPH, higher gusts.

WEDNESDAY: Mostly sunny. Highs 17-24. Wind NW 10-20 MPH. Wind chill below 10 at times.
THURSDAY: Sunny. Lows from near 0 to near 10. Highs in the 10s.
