If you’ve lived in Frederick long enough, you know the drill. You check the app, see a snowflake icon, and suddenly Every. Single. Loaf. Of. Bread. vanishes from the Giant on 7th Street. But honestly, the Frederick MD snow forecast is a fickle beast that doesn't care about your grocery list.
Right now, as of Tuesday, January 13, 2026, we are looking at a classic Maryland "tease." Today is actually pretty mild—highs hitting around 51°F—but things are shifting fast. By tomorrow night, Wednesday, January 14, we’re expecting a messy mix of rain and snow. It’s that annoying boundary line stuff where two degrees makes the difference between a pretty winter wonderland and a slushy nightmare on I-70.
The Reality of the Frederick MD Snow Forecast This Week
Weather in the Catoctin shadow is weird. Most of the time, the "big one" hits DC or Baltimore and skips us, or we get hammered while Rockville just gets wet.
For the next 48 hours, the National Weather Service out of Sterling is keeping a close eye on a system moving in Wednesday afternoon. While Wednesday day starts as rain (high of 49°F), the temperature is expected to plummet to about 24°F overnight. That is a massive drop. AccuWeather is currently projecting a 65% chance of snow transition late Wednesday night into Thursday morning.
Here’s the thing: Thursday, January 15, is going to be cold. Like, "don't leave your dog outside" cold. We are looking at a high of only 27°F with northwest winds gusting up to 40 mph. Even if we only get an inch or two of accumulation, the wind chill will make it feel like the single digits.

Why the Mountains Change Everything
You’ve probably noticed that if you live in Braddock Heights or up toward Thurmont, your driveway looks a lot different than someone’s in Downtown Frederick.
Elevation is the king of the Frederick MD snow forecast. The city sits at about 300 feet, but as you move west toward the mountains, you’re jumping up several hundred feet quickly. This "upslope" effect often squeezes out more moisture.
- The Blue Ridge Barrier: Sometimes the mountains "block" the cold air, keeping it trapped in the valley—a phenomenon called cold air damming. This is why we often see ice or freezing rain when the coast is just getting a chilly drizzle.
- The I-270/US-15 Corridor: These roads are heat islands. On days where the forecast says "1-3 inches," the asphalt might stay just warm enough to melt everything on contact, leading to that deceptive black ice we all dread.
Looking Back to Look Ahead: The 2026 Winter Context
We are currently navigating a weak La Niña winter. Historically, La Niña in Maryland means we tend to be a bit drier and potentially warmer, but it's not a rule. Local meteorologists like Justin Berk have pointed out that we’ve been in a "snow drought" for years.
Just look at the stats. The average seasonal snowfall for Frederick is roughly 20 inches. Last year? We barely scratched the surface. The winter of 2022-2023 was even worse, with some parts of central Maryland recording less than an inch for the entire season.
But 2026 is feeling a bit more active. We've already had more "frozen potential" events in early January than we did in the entirety of the last two years. The Old Farmer’s Almanac—which some people swear by and others think is a total dart throw—predicted a "colder than normal" January for the Appalachians, and so far, the mid-month dip is proving them right.
How to Actually Read the Forecast Without Panicking
Stop looking at the "accumulated inches" number four days out. It's useless. Honestly.

Meteorologists use models like the GFS (American) and the ECMWF (European). Often, they disagree wildly. One might show a foot of snow for Frederick, while the other shows the storm sliding out to sea. This is why the Frederick MD snow forecast changes every three hours.
The "Bread and Milk" Indicator
When should you actually worry?
- When the NWS issues a Winter Storm Watch: This means heavy snow is possible within 48 hours. This is your "check the flashlight batteries" phase.
- When it becomes a Winter Storm Warning: Snow is occurring or imminent. If you aren't home yet, get there.
- The "Clipper" vs. the "Nor'easter": Clippers come from Canada and are fast and powdery. Nor'easters come up the coast and are heavy, wet, and break tree limbs. We are currently looking at more of a cold-front-driven "burst" for Wednesday/Thursday.
Practical Steps for Frederick Residents Right Now
Don't wait until the first flake hits the windshield to realize your wipers are shredded.
Check your tire pressure today. Cold air makes the pressure drop (thanks, physics), and you don't want that "low tire" light coming on while you're sliding down Rosemont Avenue. If you live in a spot prone to drifting, like out toward New Market or Libertytown, make sure you have a shovel that isn't snapped in half from three years ago.
For the upcoming Wednesday night/Thursday event, the biggest risk isn't necessarily the volume of snow, but the flash freeze. With rain falling Wednesday afternoon and temperatures hitting the 20s by sunrise Thursday, anything that is wet will turn into a skating rink. Salt your walkways before the rain starts if you can, or right as it transitions.
Keep an eye on the Frederick County Public Schools (FCPS) updates. They’ve become a bit more conservative with delays lately, especially with the wind chill factor. If those 40 mph gusts hold up for Thursday morning, expect at least a two-hour delay just to get the buses warmed up and the black ice spotted.
Actionable Next Steps:
- Monitor the Dew Point: If the dew point is significantly below freezing as the rain starts on Wednesday, expect the "wet bulb" effect to turn that rain to snow much faster than the apps predict.
- Clear the Drains: Since we're getting rain first, make sure the storm drains near your house aren't clogged with dead leaves. If they are, that water will back up and freeze into a solid block on your street Thursday morning.
- Gas Up: It’s a cliché, but keep the tank at least half full. If you get stuck in a backup on Route 15, you’ll want the heater running without stressing about the E lamp.
Winter in Frederick is a game of patience. We might get nothing but a few flurries, or we might be digging out from a surprise six-incher. Either way, stay off the roads on Wednesday night if you can, and let the plows do their thing. High-pressure air is moving in for the weekend, which usually means clear skies and a chance to actually enjoy the scenery before the next system rolls through around the 20th.
