Massachusetts air feels damp and springlike at first, but winter waits just beyond the horizon. Wet pavement, shifting winds, and falling temperatures signal a pattern change that could catch Boston drivers off guard by the weekend.
According to the National Weather Service office serving eastern Massachusetts, mild conditions fade quickly as colder air presses south. A series of weak systems brings changing precipitation types, setting up a rain-to-snow transition between Saturday and Sunday across the Boston metro area.
Friday stays bright but blustery, with gusts whipping along Route 1 and I-93. Temperatures peak in the low 30s, keeping roads dry for now. Clouds thicken Friday night as the next system approaches, and light snow becomes possible late, though little accumulation is expected initially.
Saturday turns unsettled. Rain develops around midday, then mixes with snow by afternoon as temperatures hover near 40 degrees. Side streets and shaded areas may turn slick first. By Saturday night, colder air deepens. Any leftover moisture could refreeze, increasing the risk for black ice into early Sunday.
Sunday brings the most impactful weather. Snow becomes more likely by afternoon and evening, with steady flakes reducing visibility. While amounts remain uncertain, even minor accumulation could snarl travel on the Mass Pike and city arterials. Winds stay active, adding a biting chill by nightfall.
The cold holds into Monday as highs drop back into the low 30s. Drivers should plan extra time this weekend, slow down on untreated roads, and watch for rapidly changing conditions after sunset.
More winter systems are being monitored into next week as colder air settles across the Northeast. Are you traveling Sunday? Share what conditions look like in your neighborhood.
