Dangerous driving conditions overnight as colder air moves in ahead of weekend

BOSTON — A winter weather advisory is in effect for most of Massachusetts until 4 a.m. Friday due to snow, sleet, and freezing rain, according to the NWS.

MassDOT is advising the public to plan ahead if traveling Thursday into Friday as ice is a major concern following the wintery mix of snow, sleet, and rain.

The Boston 25 Weather team is predicting a coating to up to 4 inches of snow in some areas as the storm system moves across Massachusetts before the precipitation ends by mid-day on Thursday.

The advisory impacts Central Middlesex, Eastern Essex, Eastern Franklin, Eastern Hampden, Eastern Hampshire, Northern Worcester, Northwest Middlesex, Southern Worcester, Western Essex, Western Franklin, Western Hampden, Western Hampshire, Northern Berkshire, Southern Berkshire counties, Eastern Norfolk, Eastern Plymouth, Northern Bristol, Suffolk County, Western Norfolk, and Western Plymouth.

Southeastern Massachusetts and Cape Cod likely saw a coating to an inch of snow before changing to freezing rain and ice.

As temperatures dropped throughout the day, the slick roads turned icy and the uncleared snowpack will freeze.

In New Hampshire, a winter storm warning is an effect from Concord, NH to the Canadian Border, where total snow accumulations between 7 and 12 inches is possible.

In a statement, the NWS in the Granite State said, “A snowstorm will bring plowable snow to the region with a period of moderate travel impacts expected. Periods of moderate snow and low visibility will be the biggest hazards. The potential exists for snowbands that will bring periods of locally heavy snowfall late Wednesday night, which will lead to rapid snow accumulations and extremely dangerous travel conditions. The hazardous conditions could impact the Thursday morning commute.”

The rest of New Hampshire is under a winter weather advisory. Total snow accumulations between 2 and 5 inches are possible. Ice is also a concern.

Power outages and tree damage could also have an impact on communities across the region.
