Right now, if you're stepping outside in Jonesboro, you're probably feeling that sharp, dry bite in the air. Honestly, it’s one of those nights where the wind just seems to find every gap in your coat. As of late Thursday night, January 15, 2026, the temperature has bottomed out at 28°F.
It is clear. It is quiet. But man, is it cold.
The weather forecast for Jonesboro GA shows we just came off a day where the high only struggled up to 36°F. If you felt like the wind was pushing you around earlier, you weren't imagining it—northwest gusts were hitting 15 mph.
The Quick Thaw and the Friday Twist
Tomorrow, Friday, January 16, looks like a total mood swing. We’re jumping up to a high of 51°F. That’s a massive relief compared to the freezing start, but don't get too comfortable with the sunshine. While the day stays bright, the night brings a 70% chance of rain.

Basically, keep your umbrella in the car even if the morning looks perfect.
The wind is shifting, too. We’ll see a breeze coming from the south at about 12 mph, which is exactly why it’s going to feel significantly warmer before that rain moves in.
What to Expect This Weekend
Saturday is going to be a bit of a gray one. We're looking at:

- A high of 51°F (same as Friday).
- Cloudy skies all day and night.
- A 35% chance of rain during the day.
- A slight 10% chance of snow overnight as it drops to 30°F.
Now, don't go buying all the bread and milk just yet. A 10% chance of snow in Clayton County usually means a few stray flakes that vanish the second they hit the pavement.
By Sunday, the sun comes back, but the mercury takes another dive. We’re looking at a high of only 39°F with a low of 28°F. It’s that classic Georgia winter "see-saw" where you’re wearing a light jacket at noon and a heavy parka by dinner.
Long-Term Outlook: The Deep Freeze Returns
If you're looking further ahead into next week, the weather forecast for Jonesboro GA suggests we’re staying in a dry, cold pattern. Monday and Tuesday (January 19-20) are going to be sunny but bitter, with lows hitting 22°F.

We’ve seen this before in Jonesboro. January is historically our coldest month, typically averaging highs of 53°F and lows of 33°F. We are currently tracking a few degrees below those averages, which fits the 2026 outlook of a slightly colder-than-normal winter for the Southeast.
Safety and Local Context
Living here, you know the drill. The City of Jonesboro operates four outdoor warning sirens (like the ones at the Police Station and CCFD Station #13). They test them the first Wednesday of every month at noon, but they are there for the real deal—tornadoes and extreme wind.
While we aren't seeing tornado threats this week, the National Weather Service has issued statements about high fire danger. Why? Because the air is incredibly dry—humidity dropped to 25% earlier today—and when you combine that with 30 mph gusts, a small brush fire can turn into a problem fast.
Actionable Steps for Jonesboro Residents
- Check your tires: This 30-degree temperature swing from day to night causes tire pressure to drop. If your light came on this morning, that's why.
- Bring the pets in: We are hitting 22°F by Tuesday night. If it’s too cold for you, it’s definitely too cold for them.
- Hydrate your skin: With humidity sitting at 40% and lower, the "winter itch" is real.
- Friday Night Plans: If you’re heading to a game or out to dinner, the rain starts after dark. Plan for wet roads and a low of 27°F.
It’s just January in Georgia—kinda unpredictable, always a bit of a surprise, and definitely requires a few extra layers for the next few days. Stay warm out there.
