Massachusetts wakes to a brittle winter morning as Weather Alert conditions grip eastern New England. Cold air presses against windows, flags snap sharply, and pavement feels unforgiving underfoot as the new year begins.

Temperatures hover near 17 degrees early, with wind chills in the single digits across Boston and nearby coastal communities. Clouds thin gradually through the morning, allowing some sun by afternoon. Even with sunshine, highs struggle to reach the upper 20s, keeping the cold snap firmly in place.

Winds remain a factor today, especially along exposed roadways and bridges. Gusts can quickly dry pavement, but shaded areas may still hide black ice, particularly where snowmelt refroze earlier. Drivers should ease into turns and allow extra braking distance.

Tonight turns sharply colder. Skies stay mostly clear, and temperatures fall back into the upper teens. That setup keeps untreated surfaces slick into the early hours, especially on neighborhood streets and parking lots.

Saturday brings a calmer feel. Sunshine dominates, winds relax, and highs climb close to 30 degrees. It will feel brighter but not warmer. Winter coats remain essential for anyone outdoors.

Attention then shifts to Saturday night into Sunday, when a slight chance of snow develops. Any snow appears light and scattered, yet timing matters. Even minimal flakes can stick quickly with daytime highs near 29 degrees and light winds.

Sunday night turns colder again, with lows near 11 degrees, locking in whatever moisture remains. Another chance of snow appears late Monday night, signaling an active winter pattern as the first full week of 2026 approaches.

Plan winter travel carefully. Watch bridges and ramps. Keep gloves and traction-ready footwear close.
