Forecasters: On the bright side, it could be a lot colder

Boston is in the midst of the coldest air mass the region has yet seen this winter season, with this morning’s lows bottoming out at one degree below zero in the Western Massachusetts town of Leverett, the National Weather Service said.

Although temperatures in the Boston area dropped to 17 degrees, the mercury only managed to reach the single digits in other parts of the state, with a low of 2 degrees at the Fitchburg Airport and 6 degrees in Orange, said weather service meteorologist Bill Simpson.

Highs in Boston today are expected to hit 30, though with wind gusts near 25 miles per hour, wind chills will drop into the teens. By Thursday morning, temperatures will bottom out at 10 degrees, with Boston’s suburbs potentially in the single digits.

However, the Bay State got lucky, Simpson said, largely escaping the brunt of the cold front now filtering through the East. Lows of minus 18 degrees were recorded on Mt. Washington in New Hampshire this morning, he said.

“Even though this is cold, it could have been a lot colder. Most of the Arctic air is staying to the north, so we should be grateful,” Simpson said.

This afternoon, Boston could experience “a few flakes here and there, but there’s no moisture in the air,” he said, putting any sort of accumulation out of the question through Friday.

The rest of the week and into next will continue to stay dry, he said, with temperatures climbing to the low 40s by Tuesday, above the average high of 37 degrees.
