Boston, Massachusetts – Roads could turn slick within hours this morning as rain flips to a wet snow mix between 4 a.m. and 8 a.m., especially north of the Massachusetts Turnpike.
According to the National Weather Service in Boston, the early morning transition will occur before steadier precipitation tapers off by mid-morning. While widespread accumulation remains limited, areas along and north of I-90, including Worcester, Lowell, and Fitchburg, could see brief slushy coatings and reduced traction during the morning commute.
The bigger concern shifts to the afternoon and evening, when scattered snow showers and isolated squalls develop. These bursts may briefly drop visibility to near 500 feet and create quick coatings on roadways, leading to sudden slowdowns on I-93, Route 2, and I-495.
In Boston and along the South Shore, precipitation remains mostly rain early, with less impact expected. However, any snow squall that moves through could still create rapid changes in driving conditions.
Drivers should stay alert for sudden visibility drops, reduce speed during snow bursts, and allow extra space between vehicles. Conditions can deteriorate quickly even after roads appear wet.
Showers taper later tonight, but colder air settling in could allow refreezing on untreated surfaces by early Tuesday. Additional updates are possible if squalls become more widespread.
