Honestly, if you're checking the weather forecast for Deep Creek Lake, Maryland right now, you’re probably looking at a screen full of snow icons and shivering just thinking about it.
It's January 17, 2026, and the air up here in McHenry is currently a crisp 28°F. But that number is a total liar. With the wind kicking at 6 mph from the west, the "feels like" temperature is actually sitting at a biting 21°F. If you’re planning to step outside tonight, know that the sky is stubborn and cloudy, and there's about a 17% chance you’ll see some flakes drifting down.
Why the Mountain Forecast Hits Different
Most people make the mistake of looking at a Baltimore or D.C. forecast and subtracting five degrees. Big mistake. Huge. Deep Creek sits at an elevation of roughly 2,492 feet. Because we're west of the Eastern Continental Divide, our weather behaves more like the Midwest than the Mid-Atlantic.
While the rest of Maryland might be dealing with a chilly rain, we’re usually getting hammered by lake-effect snow or trapped in a "frost pocket" like the one over near Cranesville Swamp. It's beautiful, sure, but it's rugged.
For today, Saturday, January 17, we’re looking at a high of 32°F and a low of 21°F. The daytime is basically a snow show—there's a 70% chance of the white stuff. By tonight, that tapers off to snow showers with a 35% probability. If you're driving, watch out for the 12 mph western winds; they can whip that snow across the roads faster than you can find your ice scraper.
The Week Ahead: A Deep Freeze Is Coming
If you thought today was cold, brace yourself. We are about to slide into a serious deep freeze. This isn't just "sweater weather"—this is "stay inside with three blankets" weather.

The upcoming 10-day trend for Deep Creek Lake (McHenry area):
- Sunday, Jan 18: It gets real. We’re looking at a high of only 19°F and a low of 13°F. Snow showers will linger (25% chance).
- Monday, Jan 19: Expect a high of 17°F and a brutal low of 4°F. The wind is going to be the real story here, gusting at 23 mph.
- Tuesday, Jan 20: This might be the coldest day of the stretch. A high of 13°F and a low of 2°F. On the bright side? It’ll be mostly sunny. Silver linings, right?
- Wednesday, Jan 21: Temps "rebound" back to 33°F for a high, but that brings a 40% chance of more snow.
You've probably heard people talk about the "average" 100 inches of snow Garrett County gets every year. That’s a real stat, not marketing fluff. In fact, back in the winter of 2010, some parts of the county saw over 260 inches. We aren't quite there yet, but the current pattern of weak La Niña trends we’re seeing in early 2026 suggests we might see more frequent, albeit smaller, snow events rather than one massive "Snoverkill" blizzard.
Surviving the Microclimates
One thing locals know that tourists don't: the weather at the State Park can be totally different from the weather at the top of Wisp Resort.
Wisp has one of the world's largest snowmaking systems for a reason. Even when the "natural" weather forecast for Deep Creek Lake, Maryland looks dry, the mountain is often creating its own climate. If you're coming up to ski, don't just look at the sky. Look at the humidity. Tonight it's at 86%, which is actually pretty decent for snow retention.
What to Actually Pack (The Non-Obvious List)
You know you need a coat. I know you know you need a coat. But here’s what people actually forget when the mercury dips toward zero:
- Merino Wool Socks: Seriously, leave the cotton at home. Cotton holds moisture, and moisture leads to frozen toes.
- Lip Balm with SPF: The sun reflecting off the snow at this elevation will cook your skin even if it's 10 degrees out.
- Internal Layers: Think silk or synthetic base layers. You want stuff that wicks sweat so you don't get a chill the second you stop moving.
- A Real Ice Scraper: Not a credit card. Not a spatula. A heavy-duty brush with a brass blade.
The Spring Transition
Don't get too comfortable with the ice. By the time we hit late March and April, the "mix" starts. We’ve seen days where it snows in the morning, rains at noon, and hits 60 degrees by 4:00 PM. It’s chaotic. The lake usually keeps about 18 inches of ice through the heart of winter, but once that melt starts, the Youghiogheny River downstream turns into a whitewater beast.
If you’re planning a trip later in the year, keep in mind that the lake water doesn't really get "swim-friendly" (above 70°F) until late June or July. Right now? The water is basically a liquid popsicle.
Actionable Next Steps
Check the National Weather Service's 7-day forecast specifically for McHenry (zip code 21541) rather than just "Garrett County." The elevation change from Oakland to McHenry can mean the difference between rain and a three-inch accumulation.
If you're driving up tonight or tomorrow, ensure your tires are at the right pressure—cold air makes that "low tire" light pop on like clockwork. Grab some extra washer fluid (the de-icer kind) because the salt spray on I-68 will blind you in miles. Stay warm, keep the cocoa hot, and respect the mountain weather—it’s in charge, not you.
