You’ve felt it. That crisp, biting Mississippi air that hits you the second you step out of a late-night diner in Meridian. It’s January 15, 2026, and the city is currently sitting at a chilly 28°F. Honestly, if you were expecting a mild Southern winter night, the thermometer just gave you a reality check.
The wind is barely a whisper right now—just a 2 mph breeze coming off the southwest—but the humidity is hanging heavy at 84%. It’s that damp cold that gets into your bones. But here’s the thing about the meridian ms weather 10 day forecast: if you don't like what you see, just wait about twenty-four hours.
The Rollercoaster: Meridian MS Weather 10 Day Forecast
Most people think Mississippi winters are just "chilly." They’re wrong. It’s a literal seesaw. Tomorrow, Friday, January 16, we are looking at a massive jump. We're talking a high of 63°F. You'll probably see people in shorts at the grocery store by noon, then frantically digging for their heavy coats by sunset when the temperature drops back toward 31°F.
There is a 75% chance of rain Friday night. It's not just a drizzle; it's the kind of light rain that makes the roads slick and the air feel like a wet blanket.
What to Expect This Week
If you're planning your week, here is the raw data you need to survive the swings:
- Saturday (Jan 17): Mostly cloudy and back down to a high of 51°F. The low hits 27°F. Basically, the warmth of Friday was a teaser.
- Sunday & Monday (Jan 18-19): Pure sun. Bright, beautiful, and deceptive. Highs will hover between 45°F and 52°F, while nighttime lows will stay freezing at 26°F and 25°F.
- The Mid-Week Reset: Tuesday keeps the sun but stays cool at 47°F. By Wednesday, January 21, we climb back to 60°F.

Practical Survival Steps for Meridian Residents
Don't let the 60-degree days fool you. The UV index is staying low (around 2 or 3), so you won't feel the heat of the sun helping you out much.
- Check your tire pressure. These 30-degree temperature swings between day and night are notorious for triggering those annoying "low pressure" lights on your dashboard.
- Layer like a pro. You need a base layer for the 25°F mornings and something you can strip down to when Friday afternoon hits 63°F.
- Prepare for the Saturday rain. The forecast for January 24 is calling for consistent rain. If you have outdoor plans at Bonita Lakes, move them to Monday or Tuesday when the sun is guaranteed.
The humidity is going to stay high, averaging above 80% on the wet days. This means the "perceived" temperature is going to feel colder than the actual number on the screen when it's damp, and warmer when the sun finally breaks through. Stay dry, keep a jacket in the car, and keep an eye on those overnight freezes.
