It looks like the major midweek storm will come together and bring some heavy snow to part or all of Southern New England. As of midday Tuesday, computer models are trending north with the heaviest snow. If the trend continues, it looks like sleet could limit the snowfall totals in the I-95 corridor to the coast.
The brunt of the storm is expected between midnight and mid-morning on Thursday. Peak winds over 40 mph are possible near the coast, and if it’s all snow, there could be power outages due to downed trees and power lines.
I favor the heaviest snow from Danbury, CT to northern RI to the north shore of Boston. The following maps show some computer model predictions. They are not official forecasts.
The bottom-line is this will be a significant December snow event for a big chunk of New England. The exact track will determine whether it’s a big snowmaker for the coast or if sleet keeps the totals down. Quiet weather follows in its wake on Friday and Saturday. An Alberta Clipper could bring rain/snow showers late in the weekend.
The overall pattern does not look as snowy as we get closer to Christmas, so even if it’s a widespread 8″+ event, there will have to be no big warm-ups or rain events next week to keep snow on the ground for all of Southern New England on Christmas day.
