Intensifying low pressure, also know as cyclogenesis, is responsible for the 'warmer' heavy wind and minor snowfall of earlier Friday.
Roughly one inch of snow in Boston is the 3rd heaviest snowfall of the season behind 2.3" on November 28th, and 1.4" January 3rd.
Parts of coastal New England from southeastern Massachusetts, to coast Maine experienced winds gusting past 55 mph.

Now we have less wind and new cold blowing in from the northwest as the low pressure center is racing away through the maritime provinces of southeastern Canada. An area of high pressure now over the US central plains is delivering gusty west wind with colder & drier air overnight and Saturday.
Upslope snow in Vermont is diminishing with mostly clear and cold weather for all of New England to start our weekend. Overnight lows range from 0 in the north, to 15 south. Sunshine and cold wind is here for Saturday. Temperatures top out in the 10s to low 20s, wind from the west 15-25 mph.
Clear cold air Saturday night with lows again 0-15 north to south. The New England Patriots host the Baltimore Ravens under clear sky with temperatures falling through the teens, west wind 10-15 mph.
Clouds increase Sunday as low pressure over the Midwest approaches, temperatures moderate to the 20s and low 30s with wind from the southwest 15-25 mph.
Low pressure to our north, and to our south, on Monday will generate light snow, with snow or rain at the shore, highs near freezing. Cyclogenesis will once again bring heavy wind and wintry mix Monday night and early Tuesday. A few inches of snow are likely inland, with a coating possible near the shore as rain turns to snow early Tuesday. New cold is here Tuesday with brighter skies, high in the 10s to low 20s. High pressure should bring sunshine and seasonable weather Wednesday with highs in the 20s to low 30s. We are monitoring a potential coastal storm for next Thursday, with a high in the 20 to 30s, snow or rain is possible.
As always, on this fine wintry weekend, check with local recreation outlets to make sure the ice is safe.
