As snow fell this afternoon, pedestrians crossed Washington Street at the intersection of Glen Road in Jamaica Plain.

A low pressure system is bringing some accumulating snows to much of New England, including Boston and Southeastern Massachusetts.

An arctic air mass, which could be the coldest of the season thus far, will enter the region Wednesday night and continue into Friday, bringing chilly, dry conditions, according to the National Weather Service.

Only about .2 inches of snow had fallen in Boston at 3 p.m., according to the weather service. Barnstable County on Cape Cod has seen the most snow today, with Sandwich recording two inches of snow.

As of 3 p.m., State Police had not responded to any serious car accidents caused by the slippery road conditions. The Department of Transportation deployed 234 snowplows and backhoes today.

“Amazingly, there have been no crashes around Boston,” said State Police spokesman Todd Nolan. “We had two minor ones on Interstate 93 with no injuries. We are still looking pretty good.”

Snow could impact the evening commute home, however.

“We will see snow into the early evening, which will affect the evening commute,” said MassDOT spokesman Michael Verseckes. “We would ask drivers to allow for extra time to accommodate plows keeping roads free of snow and ice.”

Snow should continue through the early evening, according to the National Weather Service. Fog will develop in the afternoon, and skies will remain cloudy through the day. Temperatures will crest in the mid-30s and a west wind could gust near 21 miles per hour. Temperatures will fall into the upper teens overnight, according to the weather service.

Wednesday will be mostly sunny and temperatures will peak in the low 30s. A west wind could gust near 25 miles per hour, making it feel even colder. Clouds will develop overnight and temperatures will fall into the teens, according to the weather service. An arctic frontal passage will come to Massachusetts overnight, bringing frigid temperatures.

On Thursday, highs will only reach the low 20s, Babcock said. “The normal high is 43, so we are going to be seeing temperatures lower than that,” he said.

A northwest wind will add a bite to Thursday, with gusts up to 25 miles per hour. Skies will remain clear overnight and temperatures will drop to around 16, according to the weather service.

The arctic weather will persist into Friday, with temperatures unlikely to pass 30. Skies will be mostly sunny, and no strong winds are likely. Clouds will develop overnight and temperatures will fall to around 20.

The cold air mass will linger in the state through Saturday, and snow and rain could fall on both Saturday and Sunday. Weekend snow will most likely fall the hardest north and west of Interstate 495, Babcock said.
