Winter in Baltimore is kinda like a box of chocolates, except half the chocolates are ice cubes and the other half are surprisingly mild rainy days. If you’re looking at the baltimore 20 day forecast right now, you’ve probably noticed things are getting a bit weird.
It's January 17, 2026.
The city is currently sitting at a crisp 36°F, but honestly, the "feels like" temperature is stuck at 32°F. That’s the classic Baltimore damp cold that settles into your bones and doesn’t leave until you’ve had at least three cups of coffee from a shop in Fells Point.
The Immediate Outlook: Snow and Shivers
Let’s talk about the next few days because they are going to be a ride. Today, we’re seeing light rain with a high of 44°F, but don't get comfortable. There is a 63% chance of snow during the day, which usually means that messy slush that ruins your shoes.
Tomorrow, Sunday, January 18, the real winter vibes show up. We’re looking at a high of 34°F and a low of 22°F. The forecast shows a 45% chance of snow, and the wind is going to be coming from the northwest at 10 mph.
Basically, it's the kind of day where you just stay inside and watch the Ravens or a movie.

By Tuesday, January 20, the temperature is going to crater. We are looking at a high of only 25°F and a low of 18°F.
That's cold.
Like, "pipe-bursting" cold if you aren't careful. If you’re commuting, just know that the wind is going to stay around 12 mph, making that 25 degrees feel significantly worse.
Breaking Down the Next Two Weeks
People always ask me if it’s actually going to stay this freezing.
The short answer?

Sorta.
We see a slight "warm-up" (if you can call it that) around Thursday, January 22, where the high hits 42°F, but it comes with a mix of rain and snow. It’s that transitional Maryland weather where the atmosphere can't decide if it wants to be a winter wonderland or a swamp.
Looking toward late January
As we head into the final stretch of the month, the baltimore 20 day forecast shows a return to the deep freeze.
- Sunday, Jan 25: High of 30°F, low of 15°F. Expect snow showers.
- Monday, Jan 26: High of 23°F, low of 15°F. This might be the coldest day of the month.
- Tuesday, Jan 27: High of 29°F, low of 12°F.
Honestly, that 12-degree low on the 27th is the one to watch. When it gets that dry and cold, the humidity drops—forecasted at 79% but with very little actual moisture in the air—which means your skin is going to feel it.
Why the Forecast Keeps Changing
If you’ve lived here for more than a week, you know the Chesapeake Bay is a total wildcard. It acts like a giant heat sink. Sometimes it keeps the city just warm enough to turn a major snowstorm into a depressing afternoon of cold drizzle.

Justin Berk, a well-known local meteorologist, often talks about "Faith in the Flakes," and this 20-day window is exactly why. One day the models show a blizzard, and the next day they show a sunny afternoon with a high of 37.
The jet stream currently has a "firm winter grip" on the Eastern US. That means while we might get a random 40-degree day, the overall trend for the next 20 days is significantly colder than average.
What You Should Actually Do
Don't just look at the numbers; prepare for the reality of a Baltimore winter.
First, check your tire pressure. When the temp drops from 44 to 18 in a few days, your "low pressure" light is going to pop on. It’s physics.
Second, if you’re heading to the Inner Harbor, remember the wind off the water adds an extra layer of "nope" to the temperature.
Finally, keep an eye on those Monday and Tuesday lows. With 25 cold-related deaths already reported in Maryland this season according to the Department of Health, this isn't the time to be a hero with your thermostat or your outdoor gear.
Actionable Next Steps:
- Drip your faucets on the night of January 19th and 20th to prevent freezing pipes as temperatures hit the teens.
- Salt your walkways before Sunday evening; that 45% snow chance combined with a low of 22°F is a recipe for a sheet of ice by Monday morning.
- Check your antifreeze levels now, as the sustained sub-freezing temps starting January 25th will put your vehicle's cooling system to the test.
