If you’ve spent any time in New England, you know the drill. You look out the window at a gray sky, check your phone, and realize the "mild" winter afternoon you were promised is actually turning into a slushy mess. Honestly, it’s basically a rite of passage for anyone living in the Hub. Right now, if you’re looking at the 5 day forecast for boston ma, we are staring down a classic January roller coaster that’s going to test your layering skills and your patience with the MBTA.
Let’s be real: January 18 is starting out feeling a bit heavy. We’ve got a current temperature of 30°F, but with that southwest wind kicking around 5 mph, it feels more like 27°F. It’s that damp, bone-chilling cold that creeps into your coat sleeves while you're waiting for the Green Line.
The Immediate Outlook: Snow and Stadium Stress
Today, Sunday, January 18, is the big variable. We are looking at a high of 35°F and a low of 30°F. The headline? Snow. There’s a 44% chance during the day, jumping up to a 65% chance tonight.
For the sports fans heading to Foxborough for the Patriots vs. Texans game at 3 pm, this is where it gets tricky. While the city might see a mix, the forecast is leaning toward actual accumulation. Most local maps are eyeing anywhere from 3 to 6 inches for the Boston area, though the NWS is being a bit more conservative with a 3-inch estimate. It’s a "snow shower" kind of night that usually makes the Monday morning commute a nightmare of salt trucks and black ice.
Monday and Tuesday: The Deep Freeze Returns
Tomorrow, Monday, January 19—Martin Luther King Jr. Day—keeps the winter theme going. We’ve got light snow in the cards for the morning with a 40% chance of precipitation. The high hits 32°F, but once the sun goes down, the bottom drops out.
We’re talking a low of 20°F and winds picking up to 13 mph from the west. If you're planning on attending any MLK Day events or community service projects, bundle up.
Tuesday, January 20, is going to be the "shiver in your boots" day. It’ll be sunny, which is a nice break from the gloom, but don't let the blue sky fool you. The high is only 23°F, and the low is a staggering 12°F. With a 15 mph wind, the wind chill is going to be brutal. This is the day where you realize your "cute" winter coat isn't actually a "winter" coat.
Midweek Shifts: From Sunny to Soggy
By Wednesday, January 21, the pattern shifts again. We climb back up to 35°F, but the sky turns cloudy. Interestingly, while the daytime only has a 10% chance of snow, the night brings a 25% chance of light rain.
Yes, rain.
When it’s 12°F the night before and then it rains, you get that lovely Boston specialty: a skating rink on every sidewalk. It’s a mess.
Thursday, January 22, settles into a "typical" winter day. Partly sunny with a high of 38°F and a low of 19°F. There’s a lingering 20% chance of snow during the day, but it feels more like a passing flurry than a "get the shovel" event.
Navigating the Boston Winter Reality
People often think a 5-day forecast is a guarantee. In Boston, it’s more of a polite suggestion from the atmosphere. The proximity to the Atlantic means a five-mile shift in a storm track is the difference between six inches of powder and a rainy afternoon that just ruins your shoes.
If you're out and about this week, here is the move:
- Check the ice: Tuesday night into Wednesday is prime time for hidden patches on side streets.
- Layering is king: You need a windproof outer shell for Tuesday, but something breathable for the "warmer" 38-degree Thursday.
- Stadium prep: If you're at the game today, waterproof boots are non-negotiable.
Stay warm, keep an eye on the sky, and maybe grab some extra salt for the driveway before Tuesday’s freeze hits. The 5 day forecast for boston ma is showing us exactly why we talk about the weather so much—it’s never boring.

Actionable Next Steps:
Check your vehicle's antifreeze levels and tire pressure before the temperature drops to 12°F on Tuesday. Ensure you have a sturdy ice scraper in the car today, as the Sunday night snow followed by the Monday freeze will likely lock car doors and windshields by Tuesday morning.
