If you've lived in North Central Ohio for more than five minutes, you know the drill. You wake up to a crisp 32°F Saturday, look out the window at the light snow dusting the sidewalk, and wonder if you should actually bother shoveling or just wait for the wind to do it for you.
Honestly, the marion ohio 10 day forecast is a bit of a rollercoaster right now. We aren't just talking about a little chill; we are looking at some genuine, bone-deep cold moving in over the next few days.
Currently, as of January 17, 2026, it's 31°F outside. It feels more like 21°F thanks to a 11 mph south wind. Humidity is sitting high at 91%, which gives the air that heavy, damp feeling that makes the cold stick to your clothes.
The Immediate Outlook: Snow and Brisk Winds
Saturday is basically our last "mild" day for a while. We’re looking at a high of 32°F with a 35% chance of light snow during the day.
By the time the sun goes down, things change. The temperature is going to drop to a low of 12°F. If you’re heading out tonight, the sky should be clear, but that southwest wind is going to kick up to 17 mph. That's a sharp contrast to the afternoon.
Sunday, January 18, stays cloudy. We're only hitting a high of 22°F. Snow showers are likely at night, with a 25% chance of some fresh accumulation.
Why the Next Week is Looking Rough
Monday, January 19—Martin Luther King Jr. Day—is when the real winter wallop arrives. The high is only 18°F, but the low is a staggering 4°F.
With west winds blowing at 18 mph, the National Weather Service is already warning about potentially dangerous wind chills. Historically, January is the coldest month in Marion. While the average high is usually around 34°F, this upcoming week is trending significantly below that.
The cold doesn't let up Tuesday, either.
- High of 22°F.
- Low of 3°F.
- Sunny skies (but don't let that fool you, it's freezing).
Basically, if you have outdoor pipes that aren't insulated, this is the window where you're going to have problems.
Mid-Week "Warm-Up" and More Flurries
There is a brief reprieve on Wednesday, January 21. We might actually see 36°F. It'll feel like a tropical vacation compared to the 3°F night before, but it comes with 20 mph southwest winds.
The rest of the week settles into a pattern of "partly sunny but cold."
- Thursday: 25°F high, 16°F low.
- Friday: 31°F high, 18°F low with a chance of light snow at night.
By next weekend, January 24 and 25, we are back into the mid-20s and high teens. Sunday, January 25, looks particularly messy with a mix of rain and snow and a low of 8°F.
What the Data Actually Says
Looking at historical trends from the Marion Municipal Airport (KMNN), we are currently in the cloudiest part of the year. January typically sees about 63% overcast or mostly cloudy conditions.
What most people get wrong is thinking the snow is the biggest threat. In reality, it's the wind. The average wind speed in January is 17.7 mph, which is why 20°F often feels like 5°F.
Even Buckeye Chuck, our local weather-predicting groundhog, is getting ready for his 47th annual forecast on February 2. But until he makes his appearance at the Marion County Fairgrounds, we have to deal with the reality of this 10-day stretch.

Survival Steps for the Coming Week
Don't just look at the numbers; prepare for the impact.
First, if you're driving on Monday or Tuesday, keep a blanket and a small shovel in the trunk. With lows hitting 0°F to 4°F, a simple breakdown can become a health emergency fast.
Second, check your tire pressure. Sudden drops from 32°F to 3°F will cause your "low pressure" light to scream at you.
Lastly, if you're a homeowner, keep your cabinet doors open under the sinks on Monday night. That 3°F low is no joke for plumbing.
