Crisp Winter Sun Graces Boston Before Overnight Snow Threats

Morning: A Cold Start with Clearing Skies

Bostonians waking up this Friday, February 13, 2026, are stepping into a true New England winter morning. Early reports from the National Weather Service in Norton indicate that the day began with temperatures hovering around 30°F and a stubborn layer of gray clouds over the harbor. However, as the morning progresses, these clouds are expected to break, giving way to a mix of sun and clouds. Commuters should remain vigilant on the roads; while the sun is emerging, untreated sidewalks and bridges may still harbor patches of frost or ice from the overnight chill. The early morning humidity is near 56%, adding a damp bite to the 22°F air as the city begins its workday.

Afternoon: Bright Skies and Chilly Breezes

By the afternoon, the sun will take center stage, providing a bright but deceptive warmth. The predicted high for today will reach between 35°F and 39°F, which is slightly above the mid-winter average for mid-February. Despite the sunshine, a steady wind coming from the west-northwest at 10 to 15 mph will keep the real-feel temperatures significantly lower. Wind gusts could reach as high as 21 mph, so heavy winter coats and scarves remain essential for anyone walking through the Wind Tunnel of the Seaport or the Common. Local officials note that city services, including trash pickup and City Hall operations, are running on a normal Friday schedule, though residents are encouraged to clear any lingering ice from their frontage while the sun is out.

Evening and Night: Temperatures Plummet and Snow Returns

As the sun sets over the Charles River, temperatures will drop rapidly. By this evening, the thermometer is expected to slide into the low 20s, with some inland areas seeing lows near 12°F. Clouds will begin to thicken again after 8:00 PM as a clipper system approaches the region. While the majority of the day remains dry, a 30% chance of snow develops after 1:00 AM. This late-night system could bring light accumulation by Saturday morning, creating potentially slick conditions for early Valentine’s weekend travelers. The risk of a 'flash-freeze' is high tonight on major routes like I-93 and the Mass Pike, as any moisture on the roads will quickly turn to black ice under the sub-freezing overnight temperatures.

• Temperature Range: High of 35-39°F; Low of 12-24°F.
