Massachusetts starts the day under a biting winter chill as cold air locks in across eastern New England. Streetlights reflect off pavement that looks harmless but may hide danger beneath.
Temperatures around Boston sit near 15°F early this morning, with wind chills below zero at times. According to the National Weather Service, patches of black ice may develop on untreated roads and walkways as gusty northwest winds combine with lingering moisture. Surfaces that appear wet could actually be frozen.
Drivers should use extra caution on I-93, I-90 (Mass Pike), Route 1, and Route 128, especially on bridges, ramps, and shaded stretches. Even short trips can turn slick quickly. Plan extra time and slow down through the morning hours.
Despite sunshine later today, the cold persists. Afternoon highs reach only the upper 20s, limiting melting. Any ice that forms early may linger longer than expected. Pedestrians should also watch sidewalks, stairs, and parking lots where refreezing is common during December cold snaps.
Tonight stays cold, with lows near 20°F, keeping freeze concerns in place. Pipes, outdoor faucets, and sensitive plants should remain protected. Pets should be brought indoors during the coldest hours.
A notable shift begins Tuesday. Sunshine returns with highs climbing into the mid-30s, followed by a sharp warm-up Wednesday near 46°F. This warm-to-cold transition is a classic early winter pattern and can lead to renewed slick spots once temperatures drop again after melting.
By Thursday, clouds increase and rain becomes likely, along with gusty winds. While temperatures stay above freezing, wet roads and falling evening temperatures could set the stage for another round of slippery travel late in the week.
