Look, everyone knows Boston in January isn't exactly a Caribbean getaway. But if you're checking the weather for tomorrow in Boston, you’re probably trying to figure out if you need the heavy-duty Sorels or if your regular sneakers can handle the trek to the T.
Honestly, tomorrow—Monday, January 19, 2026—is shaping up to be a classic New England mixed bag. We’re looking at a high of 33°F and a low that’s going to dip down to 20°F. Basically, it’s that "right on the edge of freezing" temperature that makes the slush extra annoying.
The Snow Situation
If you were hoping for a massive blizzard to get you out of work, I’ve got some bad news. The daytime forecast calls for light snow, but the chance of precipitation is sitting at a modest 35%.
It’s not going to be a "bury your car" kind of day. It's more of a "wait, is that snow or just very cold rain?" kind of vibe. By the time the sun goes down, things should clear up, though there’s still a tiny 15% lingering chance of a stray flake.

The wind is coming in from the west at about 13 mph. That doesn't sound like much on paper, but if you’re walking down Seaport Boulevard or crossing the Longfellow Bridge, you’ve definitely felt how that 13 mph can bite. It’s enough to make that 33-degree high feel a lot more like the mid-20s.
Humidity and Visibility
We’re looking at a humidity level of 71%. In the summer, that’s gross. In the winter? It just makes the air feel heavy and damp.
If you're driving in for a morning shift, keep an eye out for some slick spots. With a Winter Weather Advisory in effect until 7:00 AM tomorrow, the remnants of today's snow might have turned into a lovely sheet of black ice overnight. The UV index is a measly 2, so don’t worry about the sun—you won't be seeing much of it until the clouds break late in the day.

Dealing with the Weather for Tomorrow in Boston
Since it’s Martin Luther King Jr. Day, a lot of you might be planning to head out for a bit of history or maybe just a long brunch. Here is the reality of the situation:
- The Morning Commute: If you have to be somewhere early, give yourself an extra ten minutes. Even "light snow" can mess up the Pike or the Southeast Expressway when people forget how to drive the second a flake hits the windshield.
- What to Wear: This is prime layering territory. You want a shell that can handle a bit of damp snow, but you’ll want a warm mid-layer for when that 20-degree low starts creeping in after dark.
- The Wind Factor: Since the wind is coming from the west, the buildings in the Back Bay might give you some cover, but once you hit the waterfront, it’s game over. Bring a hat. Seriously.
Is Anything Actually Happening?
Despite the chill, Boston doesn't really shut down for 33 degrees. If you’re looking to stay dry, it's a great day to hit up the Museum of Science or the New England Aquarium. If you’re feeling brave, the ice at Frog Pond will be solid, and the light snow might actually make it look kind of "Postcard Boston" for a few minutes before it turns to gray slush.
The National Weather Service notes that while the advisory ends early Monday morning, the "patchy freezing fog" from the night before might linger. It’s that weird, misty cold that seems to soak through your coat no matter how expensive it was.

Actionable Advice for Monday
Don't let the "light" in "light snow" fool you into thinking it's a dry day.
- Check the MBTA alerts before you leave; the Red Line and snow have a famously complicated relationship.
- Salt your walkway tonight if you can. That 20-degree low tomorrow night is going to freeze whatever melts during the day.
- Keep your phone charged if you're walking around—cold batteries die way faster than you'd expect when the temp hits the 20s.
Stay warm out there. It’s a typical January day in the city: cold, a bit damp, and definitely requiring at least one large Dunkin' coffee just to survive the walk from the parking garage.
