Snow, sleet, and freezing rain are in the forecast for Massachusetts on Tuesday and Wednesday, and meteorologists are warning the weather will create a “mess” for commuters.

The National Weather Service says the storm is a “considerable, potentially high-impact event” that will affect the Tuesday evening commute.

The weather system will start as snow and transition to sleet before changing to rain on Tuesday afternoon and evening, and it could end up dumping between 6 and 8 inches of snow along the state’s northern border and between 4 and 6 around the Mass. Pike and Boston.

“Significant impacts for today’s afternoon into evening commute,” the service said. “If you can, stay home, stay off the roads, today is going to be a mess as moderate to heavy snow/sleet [at rates of 1 inch per hour] hits our area beginning [at] noon.”


Most of Massachusetts is under a Winter Storm Warning, starting Tuesday afternoon through Wednesday morning.

The service advised residents to get home early before the snow fully gets underway, because “it’ll get a lot worse right after.”

Steady precipitation is expected to start in Western Massachusetts around noon on Tuesday, beginning in Boston around 1 p.m. The storm is expected to exit the region starting around 5 a.m. Wednesday in Boston and a few hours later in the interior part of the state.
