Saturday, February 28, 2026, started cool in Boston, with Logan Airport's reading near 30°F, but the day will feel milder than recent weeks, with sunshine and afternoon highs around 46°F. South winds will shift and strengthen to roughly 7–10 mph with gusts up to about 21 mph, making the afternoon breezy on exposed spots. That brief taste of warmth will not last, as an arctic front arrives Sunday, March 1, 2026, dragging in sharply colder air and a chance of light snow across the region.
Afternoon Winds Pick Up
Mostly sunny skies this afternoon will push temps into the mid 40s, with an official high near 46°F. Southerly winds at 7–10 mph are expected to gust into the 20s, so loose outdoor items can get blown around. If you are out and about, the sun will make errands feel pleasant, but a light jacket will still be your friend in the windier spots.
Sunday, March 1, 2026 Snow Threat
Light snow is likely on Sunday, March 1, beginning after about 9 a.m. and tapering by sunset, and forecasters with the National Weather Service Boston/Norton say most places are likely to see a trace to 1 inch, with 1–2 inches possible in higher terrain. Confidence in totals is lower than normal, and the agency notes moisture is limited and hourly rates should stay light, so keep an eye on timing if you have afternoon plans. Temperatures will fall through the day, with highs near 35°F before dropping into the teens Sunday night.
Weekend Into Next Week
By Sunday night into Monday, March 2, 2026, arctic air settles in. Lows inland will drop into the low single digits and Monday's high should only reach the mid 20s. The pattern moderates midweek, but another system late Tuesday into Wednesday, March 3–4, 2026, could start as snow, then change to a mix or rain as warmer air moves in. Plan for a bitterly cold Monday and watch forecasts on Tuesday if you have travel or outdoor plans later in the week.
Commuter Note
Transit and marine impacts are possible. The City of Boston notes an MBTA Orange Line suspension between Back Bay and Forest Hills starting Saturday, February 28 and continuing through March 8 for signal work, with shuttle buses and commuter-rail alternatives in place, so allow extra travel time. Boaters and ferry riders should expect choppy coastal waters and the potential for small-craft-advisory-level gusts Sunday night into Tuesday, so check official updates before heading out. If you rely on ferries or have late-night plans on Sunday, give yourself extra time and dress for slush and cold.
Bottom Line
Enjoy the milder Saturday, but get ready for a sharp turn colder on Sunday into Monday, with light snow that could slow travel. Keep close to the latest forecasts and give yourself extra time for commutes, particularly if your trip involves shuttle buses, ferries, or higher ground. We will update readers if warnings or advisories are issued.
