Classic grinch storm on the gfs. 50s and rain on Christmas Day. We can hardly lock in a snowstorm 48 hours out yet you know the grinch storm is going to come to fruition.
Would love to have a house on Lake Waramaug in the winter during a snowstorm. Either way I think your area still has a decent shot at this. At the very least it could be a fun transition to a few hour thump of snow at the end.
