Boston started Friday, Feb. 27, 2026 on the bright but brisk side, with Logan (KBOS) clocking in near 27°F at 5:40 a.m. ET. Sunshine will take the edge off through the day, nudging afternoon temperatures into the upper 30s for a dry, calm finish to the work week.
Afternoon Into Saturday
Light southwest breezes and wall-to-wall sun should help push Boston into the upper 30s this afternoon. Saturday, Feb. 28 looks like the weekend standout: highs near 50°F, mostly sunny skies, and generally friendly weather for anything from errands to a stroll along the Charles. If you are picking a day for outdoor plans, Saturday is the clear winner.
Sunday Snow Chance Then Arctic Air
A colder front sliding in on Sunday, March 1 could drop light, accumulating snow in the afternoon and evening. Most neighborhoods are in line for anywhere from just a coating to about an inch, while higher terrain could see 2–4 inches in a higher‑QPF setup. On the other side of that front, a true Arctic airmass settles in Sunday night into Monday, March 2, sending lows into the single digits and holding daytime highs to the mid‑20s, according to the National Weather Service.
Mariners And Commuters
Outer coastal waters remain under a Small Craft Advisory through 1 a.m. Saturday, with seas running near 5 feet, so small‑boat operators should take it seriously and check the latest marine updates before leaving the dock.
On land, Friday travel should be smooth. Sunday is the one to watch: even a brief burst of snow combined with dropping temperatures could turn untreated roads, sidewalks, and steps slick in a hurry, so build in extra time if you have to be out.
What To Do
Use the quiet stretch before Sunday night to charge phones and line up extra warm layers in case the cold complicates late‑night or early‑morning travel. Enjoy Saturday’s milder air while it lasts, and keep an eye on forecasts Sunday evening if you have appointments, commutes, or shifts to start the week.
Earlier Coverage
We previously covered last week's much stronger nor'easter; this incoming system is expected to be lighter for most neighborhoods. Officials and utilities are still assessing impacts from that earlier storm, so stay tuned to local updates as we head into the colder start of next week.
