If you stepped outside in Baltimore yesterday, you probably didn't need that heavy parka. It was almost 15 degrees above the normal January high. But honestly, Maryland weather loves a good plot twist, and the 10 day weather for Baltimore MD is currently serving up a massive reality check. Winter isn't just "coming" anymore; it’s basically kicking the door down.
Right now, we are looking at a serious temperature crash. We’re talking about a 20-degree drop within 24 hours. If you’re a fan of "Faith in the Flakes," you might finally get your wish, though it’s looking more like a messy mix than a postcard-perfect blizzard.
The Immediate Shock: This Weekend's Outlook
Today, Thursday, January 15, is the pivot point. The morning started with some lingering clouds, but the sun is trying to peek through. Don’t let that brightness fool you. Highs are struggling to reach the mid-30s, and the wind is the real story here. We’re seeing gusts coming out of the west at 30 to 40 mph. It feels like 21°F out there right now, and it’s only going to get biting as the sun goes down.
Friday and the First Flurry Chance
Friday keeps the chill alive. Expect a high around 36°F with plenty of clouds. There’s a disturbance moving in that could trigger some light snow showers—about a 30% chance. Most meteorologists, like the team over at WJZ, are watching the inland areas for a dusting, but don’t expect to break out the shovel just yet.
Saturday’s "Wintry Mess" Potential
Saturday is the day to watch if you have plans near the Inner Harbor. We have a clipper system swinging through. It’s a weird one—temperatures might actually climb to 44°F by the afternoon, but the morning starts with a 50% chance of light snow. Since the ground is still relatively "warm" from our recent mild streak, anything that falls will likely turn into a slushy rain-snow mix by lunch.

10 Day Weather for Baltimore MD: The Deep Freeze
Once we get past the weekend "slush-fest," the real Arctic air moves in. This isn't just a cold snap; it’s a pattern shift. The jet stream is dipping hard into the Eastern US, and Baltimore is right in the crosshairs.
- Monday (MLK Day): Brutal winds. Even with a high of 32°F, the wind chill will make it feel like the teens.
- Tuesday, January 20: This is looking like the coldest day of the season so far. We are forecasting a high of only 23°F and a low of 10°F. If you have outdoor pipes that aren't insulated, this is your warning.
- Wednesday & Thursday: The sky clears up, but the "warm-up" is slow. We’ll be lucky to hit 39°F by mid-week.
Beyond the Thermometer: What This Means for You
Usually, Baltimore winters are a battle between the moisture from the Atlantic and the cold air from Canada. Right now, the cold is winning, but the moisture is lagging. This is why we are seeing "trace" amounts of snow instead of inches. According to the latest data from BWI, we are actually in a significant rainfall deficit—down nearly 17 inches over the last two years. While we need the precipitation, most of us would prefer it didn't come in the form of a flash freeze on I-95.
Living with the Rollercoaster
Basically, you’ve gotta layer up. The humidity is dropping to around 24% by Tuesday, which means "dry cold." Your skin will feel it, and your heating bill definitely will too.
When looking at the 10 day weather for Baltimore MD, the most important thing to track isn't just the high temperature, but the overnight lows. We have several nights coming up where we stay well below freezing. This creates that classic Maryland "black ice" scenario, especially on Thursday and Friday mornings where lingering moisture from the night before freezes solid before the morning commute.
Actionable Steps for the Next 10 Days
Don't wait until Tuesday morning to realize your car battery is dead or your hose is still attached to the house.
- Check your tires today. Drastic temperature drops cause tire pressure to plummet. That "low pressure" light is almost guaranteed to pop up this weekend.
- Disconnect outdoor hoses. With a projected low of 10°F on Tuesday, any water trapped in a hose connected to your house can freeze and crack the internal pipe.
- Watch the Saturday morning "switch." If you're driving early Saturday, watch the bridges. They freeze faster than the roads, and with the rain-to-snow transition, they'll be slick.
- Humidifier Check. The air is about to get very dry (20-30% humidity). Get your humidifiers cleaned and ready to help with the inevitable dry winter throat.
The outlook for the end of January suggests we might see another "milder" bump toward the 25th, but for now, the Arctic gate is open. Keep your ice scraper in the front seat, not the trunk. You're going to need it.
