Boston, MA – The early December chill hangs in the air across Massachusetts this morning, but all eyes are on a developing snow-to-rain system set to cross the state by midweek. For now, skies remain calm and bright — a short-lived pause before another round of wintry weather tests commuters and travelers along the I-93 and I-95 corridors.
According to the National Weather Service in Boston, Tuesday night brings a 40% chance of snow developing before midnight, with light accumulation possible north and west of the city. Temperatures near 32°F will rise toward 40°F overnight, allowing a rain/snow changeover into early Wednesday.
By Wednesday afternoon, expect steady rain with highs reaching the mid-40s, along with gusts up to 25 mph. Roads may turn slick as precipitation transitions between frozen and liquid forms, especially in shaded or untreated areas. Reduced visibility could affect travel during the morning commute, and drivers are urged to plan extra time if heading out early.
Thursday brings calmer, partly sunny conditions with highs near 39°F, followed by a chilly, bright Friday. Forecasters are already watching long-range models showing Arctic air sweeping into the region between Dec. 11–17, potentially dropping highs to 80% below average and setting up another winter weather stretch across New England.
For now, enjoy Monday’s sunshine and prepare for shifting conditions — snowflakes Tuesday, rain Wednesday, and cold winds by the weekend.
