It's officially winter! The Winter Solstice occurred at 11:28 am. While today was quiet, the first full day of winter will certainly feature some winter conditions.
Temperatures will fall into the teens tonight with increasing clouds. It will remain dry overnight, however those dry conditions will be short-lived.
Winter Weather Advisory will go into effect for all of western Mass early Friday morning as snow and freezing rain is expected throughout the day on Friday.
Light snow will develop by Friday morning, first falling through the Berkshires and Franklin County. By midday, all of western Mass will be seeing snow. Snowfall forecasts look to be light from the Mass Pike and south - possibly a coating to an inch. North of the Mass Pike to Route 2 in Franklin County should see between 1-3", while north of Route 2 will see the jackpot of 3-6"+.
A warm front will move in from north to south, but the cold air will get trapped at the surface. This will melt the snowflakes as they fall, but causing the rain to freeze on the road surfaces. Light freezing rain is expected overnight into Saturday, potentially lasting into the early afternoon. A tenth to a quarter of an inch of ice may accumulate, which could lead to hazardous travel. Friday's evening commute and early Saturday may see the worst of the travel conditions.
Temperatures will finally creep above freezing Saturday afternoon. That ends the freezing rain risk, as just a plain, cold rain falls Saturday afternoon and evening. The system will finally exit New England by late Saturday.
Sunday is looking like a decent day overall. Temperatures will rise to near 40 as high clouds push in for the afternoon. Light snow looks to move in by midnight as a low pressure center moves off the coast. It's looking more likely that Christmas morning will feature some accumulating snow. Since we are days away from that system, the track and accumulations will become clearer as we near Christmas.
Following Christmas, 20s return to western Mass as cold air spills in from Canada.
