Mount Airy is a weird place for weather. Honestly, if you’ve lived here long enough, you know the drill. You look at the Baltimore forecast, see "light rain," and then walk outside to find three inches of slush on your windshield. It’s the "Parrs Ridge effect," and it makes pinning down a reliable weather forecast mt airy md feel like a full-time job.
Right now, as of Sunday, January 18, 2026, we’re sitting in that classic mid-winter funk. The current temperature is exactly 32°F, but with a 3 mph breeze coming out of the southwest, it feels like 29°F. There’s a light rain falling, though with the humidity pegged at 95%, it’s more of a damp, heavy mist that sticks to everything.
Why the Ridge Changes Everything
Most people don't realize that Mount Airy sits at an elevation of about 830 feet. That doesn't sound like much until you realize we’re the high point between the Monocacy Valley and the Patapsco. When a storm moves in from the west, that air hits the ridge and lifts. It cools down just enough to turn a Frederick "rainy day" into a Mount Airy "snow event."
If you're checking the weather forecast mt airy md for the rest of today, expect the clouds to stick around. We might see a stray snow shower—there's about a 20% chance this afternoon—but the high will only struggle up to 34°F. Tonight, things clear up slightly, and the temperature is going to bottom out at 20°F. If you haven't dripped your faucets yet, tonight’s the night to start thinking about it.
The 10-Day Outlook: A Deep Freeze is Coming
Looking at the week ahead, Monday (January 19) looks deceptively nice. It’ll be sunny with a high of 35°F, but the wind is going to kick up to 18 mph from the southwest. That’s going to bite.
Then, Tuesday hits. That’s when the real arctic air arrives. We’re looking at a high of only 24°F and a low of 13°F. This isn't just "jacket weather"; this is "find your heavy wool socks" weather.

- Wednesday, Jan 21: Partly sunny, high of 36°F, low of 13°F.
- Thursday, Jan 22: High of 38°F, mostly clear at night.
- Friday, Jan 23: Clouds return, high stays around 34°F.
- The Weekend Threat: Keep an eye on Sunday, Jan 25. The current models are showing a 45% chance of snow overnight with a high of only 22°F.
By Monday, Jan 26, the chance of snow jumps to 75%. If you need to hit the Safeway on Ridgeville Blvd, do it before the weekend. You know how the bread and milk aisles look the second a snowflake is mentioned.
Surviving the Mt. Airy Microclimate
The wind here is a real factor. Because of the open farmland and the ridge elevation, we get gusts that people down in Damascus or Sykesville just don't deal with. On Monday, those 18 mph winds will make that 35°F high feel like it’s in the low 20s all day.
It's also worth noting the "I-70 Divide." Often, the weather forecast mt airy md acts as a literal boundary. You’ll see heavy snow north of the highway toward Taylorsville, while south of the town toward Woodbine, it’s just a cold drizzle. It’s frustrating for commuters, but it’s just part of the local charm.
Practical Steps for the Next 48 Hours
Since we're staring down a low of 13°F by Tuesday, here's what you actually need to do. First, check your tire pressure. Cold snaps like this will trigger your TPMS light faster than anything. Second, make sure your outdoor hoses are disconnected. It sounds basic, but every year someone’s pipes burst because they forgot the spigot in the backyard.
Lastly, if you’re commuting toward DC or Baltimore on Monday morning, watch out for black ice. Since we have light rain today and a hard freeze tonight (dropping to 20°F), any untreated side roads are going to be skating rinks by 6:00 AM tomorrow.
Stay warm out there. The ridge is beautiful in the winter, but it doesn't play nice with your heating bill.
