After a day of windless snow, really ramping up here on Cape Cod in the last hour. Gusting +30mph, sustained 15-20mph.
Totally different feel outside, could make a run at +6 inches with these conditions.
HRRR continues to show a narrow band of 2-4 inches of extra snow for parts of Cape before this one wraps up.
Very tight gradient however, 5-10 miles could be the difference between a dusting and higher amounts.
Black line is the 30-year rolling average; for BOS the 1930-1960 period was around 32.7F. Current "climate" is about +2F greater at 34.6F.
Most notable is that pre-2002 and over the course of +125 years, BOS did not once see a Dec-Mar winter where avg. temps were +37.5F. Since 2002 we've seen 6 years +37.5...

Looks like this started on the earlier side. Will be interested to see how these bands move across and set up here on the Cape.
Wellfleet and Yarmouth looks to be in a good spot at the moment.
Tapped out between 2-2.5” here in Barnstable. Once we lost the heavy echos of the main precip field, the accumulating snow went with it.
All things considered, an enjoyable event with an interesting snowfall distribution from Boston to Cape Cod.
00z NAM turning back the clock a few days to show a nice moderate event tomorrow evening, with a Cape Cod jackpot if it can stay cold enough. Likely cut these numbers by 25-50%…but would be a beautiful and COLD weekend.
