Honestly, if you’re living in Charm City right now, you’ve probably noticed the air has that specific mid-January bite that makes you want to stay buried under three weighted blankets. It's cold. Like, really cold. But checking the 7 day forecast for baltimore maryland today, January 17, 2026, reveals a week that’s basically a rollercoaster of slush, sunshine, and some seriously aggressive wind chills.
Most people think Baltimore winters are just gray and damp, but this upcoming stretch is proving to be a bit more dramatic than the usual Inner Harbor drizzle.
The Immediate Mess: Slush and Sleet
Saturday is starting off pretty gross. We’re looking at a high of $6°C$ (about 43°F), but don’t let that single digit fool you into thinking it's mild. The morning is bringing a messy "rain and snow" situation.
The probability of precipitation is sitting at a hefty 72% for the daytime hours. If you're heading out to Fells Point or trying to grab a coffee in Canton, expect slush. It’s that heavy, wet snow that doesn't really "stick" in a pretty way—it just makes the sidewalks slippery and ruins your suede boots. By tonight, things dry out slightly, turning mostly cloudy with a low of $2°C$.
Sunday, January 18, is when the "real" winter vibes settle in. The high drops to $2°C$ and the low plunges to $-4°C$. We’re expecting light snow during the day with about a 35% chance, so maybe a dusting for the Ravens fans or anyone heading to the museums.

7 Day Forecast for Baltimore Maryland: The Deep Freeze
If you thought Sunday was chilly, Monday and Tuesday are here to hold your beer. Monday stays sunny—which is a total tease—with a high of $3°C$, but the overnight low hits a brutal $-7°C$.
Then comes Tuesday, January 20. This is the day to double-check your pipes. The high won't even break the freezing mark, topping out at $-3°C$ (roughly 26°F). Overnight? We are looking at $-9°C$.
It's a dry cold, though. Zero percent chance of snow. Just pure, unadulterated arctic air.
Mid-Week Fluctuations
- Wednesday (Jan 21): A weird one. Partly sunny during the day ($3°C$), then a mix of rain and snow at night as the low hits $-9°C$ again.
- Thursday (Jan 22): Slightly "warmer" at $4°C$ with a 20% chance of rain/snow. Clear skies return by nightfall.
- Friday (Jan 23): Back to the grind. Partly sunny with a high of $2°C$ and a low of $-3°C$.
What Most People Miss About Baltimore's Climate
There’s this misconception that because we’re on the water, we don’t get "real" cold. Tell that to the wind coming off the Patapsco. On Monday, we’re expecting 15 mph winds from the southwest. In the city canyons of Downtown, that's going to feel significantly sharper than the thermometer suggests.
Historically, January is Baltimore's coldest month. According to data from the Maryland State Archives and the National Weather Service, our average low is usually in the mid-20s (Fahrenheit), so hitting those $-9°C$ (approx 15°F) marks at night is definitely on the lower end of the "normal" spectrum.
Basically, the 7 day forecast for baltimore maryland is a reminder that winter in the Mid-Atlantic is never just one thing. It's a mix of humidity (hovering around 30-60% this week) and shifting wind directions that can move from a "balmy" south breeze to a biting northwest gust in about six hours.
Staying Ahead of the Ice
If you're commuting, Tuesday is your biggest red flag. Even without precipitation, any residual moisture from Sunday or Monday could create black ice patches, especially on the bridges or those narrow side streets in Federal Hill.
Actionable Prep for the Week:
- Vehicle Check: If your battery is more than three years old, those $-9°C$ nights on Tuesday and Wednesday might be its breaking point. Get it tested now.
- Layering: Don't just wear one heavy coat. The humidity makes the cold "creep" in. A moisture-wicking base layer is actually more useful than a thick sweater here.
- Pet Safety: If your dog isn't a Husky, Tuesday's highs of $-3°C$ are too cold for long walks. Keep the potty breaks quick.
- Pipe Protection: For those living in older rowhomes with uninsulated exterior walls, keep a slow drip going in your faucets Tuesday night to prevent a burst.
The week ends with a "mostly cloudy" Saturday, January 24, with a high of $2°C$ and a chance of snow showers late. It’s a classic January grind in Maryland. Stay warm, keep the salt handy for the steps, and maybe skip the harbor walk until Thursday.
