A powerful winter storm is blasting New England with heavy snow and strong winds, all before the temperature takes a nose dive on Sunday night into Tuesday.

Coastal New England from Massachusetts to Maine has been the hardest hit so far in the storm. Nearly two feet of snow has fallen in eastern Massachusetts and Maine since snow began on Saturday afternoon. Through 9:30 a.m., 22 inches of snow had fallen in Acushnet, Mass., and Milton measured 21 inches. Salisbury and Ipswich, Mass., have seen more than 20 inches.

Similar totals have been recorded in Maine, where York County has seen 21 inches so far, and Rockingham County has accumulated as much as 20 inches.

By 7 a.m., Boston had totaled 10.2 inches from this storm, though that has undoubtedly climbed since heavy snow continued for a few hours beyond that. With over 50 inches of snow so far — and just halfway through the month — February 2015 is now the snowiest on record for Boston, beating out January 2005 when 43.3 inches of snow fell.

This weekend’s snow also makes it the third snowiest season on record for Boston, with 89.7 inches so far. With a total of 107.6 inches, 1995-1996 has long held the title of snowiest season on record, but this winter is inching closer every day. After this storm, Boston will likely need just another 10 or 12 inches of snow to break the record.

Blue Hill Observatory, south of Boston, has measured a new all-time snow depth record during this storm:

Conditions deteriorated rapidly around 5 a.m. in Boston when heavy snow moved in, and in combination with wind gusts over 20 mph, visibility dropped to less than ¼ mile. Periodic whiteout conditions continued through the late morning.

Though the snow seems to have peaked in intensity in the hours after sunrise, wind gusts continue to climb. A 62 mph wind gust was recorded on Nantucket Island around 9:30 a.m., with sustained winds of 46 mph.

Peak wind gusts through 10:15 a.m.
62 mph on Nantucket
57 mph in Marstons Mills, Mass.
54 mph in Rockport, Mass.
55 mph near Hyannis, Mass.
51 mph in East Falmouth, Mass.

Strong winds have contributed to lofty snowdrifts, which have piled up to six feet in some places.

The storm was so strong along the coast on Sunday morning that it began to thunder — an indication of a very intense snow event. A seemingly frozen Jim Cantore, who had already been out for hours in the frozen New England tundra, rejoiced when the first clap of thundersnow rang out.

Power outages remain a concern given the Arctic blast that this storm will usher in from the north. Monday morning wind chills will be more than 20 degrees below zero in New England. Highs on Monday may not climb past 10 degrees in eastern Massachusetts — according to the National Weather Service in Boston, this hasn’t happened in the region since the Arctic outbreak in January 2004.
