Boston temperatures are set to plunge to their lowest levels of the season this Sunday, with brutal wind chills and another round of snow expected to make for a difficult day to be outside. The combination of Arctic air and a coastal system could bring dangerous “feels-like” readings and fresh accumulation on top of what’s already on the ground.
Boston will feel like –20° this weekend with wind chills at -25
Forecasts point to a sharp drop in temperatures on Sunday, with actual air temps stuck in the teens and single digits for much of the day. With strong winds factored in, wind chills could fall to around -25 at times, especially during the early morning and evening hours. That’s cold enough to make even short trips outside uncomfortable and potentially unsafe without proper layers. Don’t fall for that 2° reading on your phone; it’s going to feel much, much colder.
At the same time, a coastal storm is expected to track close enough to New England to spread snow across the Boston area for several hours. Current expectations suggest a plowable snow event, with a broad zone of light to moderate accumulation and the potential for heavier bands depending on the exact storm track. Visibility and road conditions could deteriorate quickly during any periods of steadier snow.
More snow en route to Boston
Snow is most likely from Sunday morning into the afternoon, tapering toward evening as the storm pulls away. In that window, several inches of new snow are possible, and could pose a threat particularly on untreated roads, side streets, and sidewalks where the bitter cold will help snow stick and limit melting.
Because the storm’s placement will dictate where the heaviest band sets up, totals could still shift, but the signal is strong enough that Boston residents should plan for meaningful accumulation rather than a dusting. Gusty winds will also blow snow around, creating localized drifting and briefly reduced visibility, especially near the water and on open stretches of highway. Boston should prepare for what will be a coating up to 3 inches of snow.
The snow is traveling south from Canada, so it is still not confirmed just how much snow is on the way, but either way, expect especially frigid temperatures this weekend—the coldest of the year! Luckily the forecast for the following week climbs it the 20s and 30s which is basically summah compared to just how cold it’ll get this weekend.
