A fast-moving storm that dumped 4 to 8 inches of powdery snow and sent cars sliding during the morning commute swept out to sea, leaving a bright sun hanging in the afternoon sky.
The next weather challenge for Massachusetts residents: Bone-chilling temperatures during the weekend that could push the thermometer to below zero in Boston and down to 25 below zero in Western Massachusetts.
Scores of fender-benders and spinouts were reported on the highways after the storm arrived early this morning. But there were no serious injuries, said State Police spokesman David Procopio.
One accident, in which a State Police trooper received injuries that were not life-threatening, resulted in charges against the driver. Peterson Frederico, 37, of Revere faces charges of driving an unregistered motor vehicle, speeding, and failure to take care in stopping, in the crash at 9:08 a.m. on the Massachusetts Turnpike in Brighton. Frederico's car allegedly rear-ended a cruiser occupied by Trooper Ulises Ayuso, 49, who was responding to a prior crash.
Procopio urged people to continue to take it slow and leave plenty of space between their vehicle and other vehicles tonight -- and through the weekend. He said black ice could be a particular problem for motorists.
By late afternoon, the city of Boston had dropped its snow emergency, as did the Department of Conservation and Recreation.
About 100 flights were canceled at Logan International Airport earlier today, but now that the snow has subsided, the rebooking has begun. "Everything's pretty much back to normal," said spokesman Phil Orlandella. "The airlines are telling us they should be back in full swing this afternoon."
The MBTA reported problems on individual subway, bus, and commuter lines early in the day. It closed the Mattapan High Speed Line due to the snow, but it had reopened by late this afternoon. MBTA service updates can be found here.
Dozens of schools, colleges, and universities were closed due to the storm. State workers were allowed to come in late. But the state court system and businesses said they were open as usual.
The focus now turns to the weekend, when temperatures are expected to plummet to subzero levels around much of southern New England.
On Saturday night, temperatures are expected to fall below zero in the northwest sections of the state, with single numbers to teens on the coastal plain.
Sunday night is expected to bring the coldest temperatures of the season -- and the coldest airmass since 2005 -- across the region. Temperatures of 25 below zero are possible in the interior northwest valleys and near zero or slightly below along the south coast. Boston could see its first below-zero temperature since Jan. 22, 2005, with an expected minimum of 1 below.
Monday is also expected to be cold, according to the latest National Weather Service forecast discussion.
Beyond the weekend, forecasters are warning that there may be -- yes -- more snow in the forecast. A "major winter storm" could affect the area Wednesday or Thursday or both days, the forecasters said.
