Icy Winter Storm Could Put The Freeze On Massachusetts

The first of what looks to be two winter storms this week will cover much of Southern New England in a thin sheet of ice overnight.

Snow and sleet will begin late Monday afternoon or early evening. The icy precipitation will turn into freezing rain overnight as temperatures hover right around 32 degrees.

Little to no snow accumulation is expected, but slick roads could greet many Tuesday morning. The most ice accumulation — up to a half-inch — is expected west of I-495.

The icy conditions prompted the National Weather Service to issue a winter weather advisory for nearly all of Massachusetts.

"Plan on slippery road conditions," the Weather Service said. "The hazardous conditions could impact Monday overnight travel and the Tuesday morning commute"

Another storm is expected to move at the end of the week and cause potentially significant issues, but the forecast is still early.
