Heavy Snow and Shivering Temps: Winter Refuses to Quit in Boston

Winter’s Frigid Grip Tightens as March Begins

Boston residents waking up this Sunday, March 1, 2026, are finding that the transition to spring is still a distant dream. While the calendar may have turned a page, the atmosphere is firmly stuck in a deep freeze. Today's forecast calls for a significant winter event, as a late-season storm system moves through the region, bringing both heavy snow and some of the coldest temperatures we have seen in weeks. Whether you are heading out for a morning coffee or planning your commute for the week ahead, today is a day to stay vigilant and bundled up.

Morning: A Frigid and Frosty Start

The early morning hours began with clear skies and a biting chill. At approximately 3:00 AM, temperatures in the city were hovering at a crisp 32°F, but high humidity around 83% made the air feel significantly damper and colder. As the sun rises, cloud cover is expected to increase rapidly. By mid-morning, the sunshine will be completely obscured by a thick gray canopy, signaling the arrival of the day's main weather event. Residents can expect the first flakes of snow to begin falling before noon, with temperatures remaining stagnant in the low 30s.

Afternoon: Heavy Snow Accumulations Expected

The heart of the storm arrives this afternoon. Predictions indicate that Boston could see substantial snowfall, with some models suggesting up to 5.9 inches of accumulation by the end of the day. The high for the afternoon is expected to reach only 35°F, just enough to keep the snow heavy and wet. Visibility will likely drop significantly during peak snowfall periods, making travel throughout the city hazardous. If you must be on the roads, expect delays on major routes and slushy conditions on side streets.

Evening and Overnight: The Big Chill

As the sun sets, the snow will begin to taper off, giving way to clearing skies. However, the end of the precipitation brings a different kind of danger: a dramatic drop in temperature. The mercury is set to plummet to a bone-chilling low of 11°F overnight. With clearing skies and wet surfaces, the risk of 'black ice' will be extremely high on walkways and roads. The humidity is expected to drop to around 63%, but the dry, arctic air will bring wind chills that feel much colder than the actual thermometer reading.

Safety Alerts and Precautions

• Snow Removal: Due to the moisture content of the snow, it will be heavy to shovel. Take frequent breaks to avoid overexertion.
• Travel Hazards: A 31% to 80% chance of precipitation throughout the day means roads will remain slick. Avoid non-essential travel during the afternoon hours.
• Extreme Cold: With an overnight low of 11°F, ensure that pets are brought indoors and that pipes are properly insulated to prevent freezing.
