After cold sun, blustery northwest wind with a wind chill in the teens & 20s, clouds thicken tonight, light snow arrives 11 PM at the NY border of NewEng and 3-4 AM Eastern NewEng. Cold roads, lows around 20 means even light snow sticks. Continues thru Fri AM, including Cape Cod!

After the aforementioned coating-2" for some Fri AM, sun comes out Fri PM but next disturbance arrives Christmas AM. Brief window of opportunity near/north of MA Pike for early AM snowflakes before change to light freezing rain, then stray raindrops rest of day south, snow north.

Disorganized storm over NewEng Christmas gains organization late day to night, swath of accumulating snow sets up north of storm center, namely Northern NewEng. This is total Fri-Sun snow, I think there's room to raise this forecast north & note some snow may fall Sun AM south.

Looking ahead to next week, it'll be a busy week across the country with multiple rounds of atmospheric energy ejecting into a fast jet stream from a stormy West Coast. Feet more snow will fall in some of the Rockies. New Year's Eve may bring rain and snow to the Northeast.
