It is Saturday, January 17, 2026, and if you are standing anywhere in Fulton County right now, you’re probably looking at a gray, stubborn sky. Honestly, it is one of those classic Georgia winter mornings where the air feels heavier than the actual temperature suggests.
The current thermometer reading is 47°F. That sounds manageable, right? But with humidity sitting at a thick 89%, it’s that damp kind of cold that crawls right under your jacket. Most of us call this "bone-chilling," even if a New Yorker would laugh at us for wearing a parka in the 40s.
The Saturday Forecast: Rain, Then Maybe a Surprise?
Basically, today is a bit of a tease. We’re heading for a high of 54°F, which isn't half bad for mid-January. But don't let the afternoon peek of sun (if we get one) fool you. The clouds are sticking around, and there is a 35% chance of rain during the day.
Then things get weird.
Tonight, that rain chance holds steady at 35%, but the temperature is going to bottom out at 35°F. The forecast is calling for light snow. Now, if you’ve lived in Atlanta or North Fulton for more than five minutes, you know what happens when the "S-word" gets mentioned. Bread and milk aisles start looking like a ghost town.

But let’s be real—35°F is right on the edge. Usually, this means we get some pretty slushy flakes that melt the second they hit the pavement on I-285. Speaking of the Perimeter, there was already a tragic three-vehicle crash on I-285 West near Old National Highway this morning. Whether it was the visibility or just typical Saturday chaos, it's a reminder that "mostly cloudy" and 47 degrees still requires some focus behind the wheel.
The Rest of the Week at a Glance
If you’re planning your week, Sunday is going to be the "reset" day.

We are seeing a lot of 20-degree nights coming up. That’s the real story of Fulton County GA weather this time of year. It’s not the daytime highs that get you; it’s the overnight freeze that kills your lantana and makes your tire pressure light pop on.
Why Our Weather Is Actually Getting Weirder
Kinda feels like the "Old Farmer’s Almanac" was onto something this year. They predicted winter temperatures would be below normal for the Southeast, and seeing 26°F on a Monday night in 2026 pretty much confirms it.

There is a phenomenon we deal with here called "the wedge." Meteorologists call it Cold Air Damming. Essentially, cold air gets trapped against the Appalachian Mountains and slides down into Northeast Georgia, hitting places like Alpharetta and Roswell harder than the southern part of the county. It’s why you might see ice in Milton while it’s just a cold drizzle in Union City.
We’re also seeing a trend where the "1-in-100-year" storms are happening way more often. According to the Director of the UGA Weather Network, things that used to have a 1% chance of happening are now sitting at a 10% chance. That means more flash flooding and more "Snowmageddon" scares.
Looking Back to Look Ahead
Remember 2014? The year the "Snowpocalypse" paralyzed the city? People were stranded on I-75 for 20 hours. That happened because of a tiny shift in the moisture track—just a couple of miles made the difference between a wet road and a skating rink.
Fulton County actually has a moderate natural disaster risk score (around 42% according to Augurisk). Most of that isn't from earthquakes or wildfires—it’s severe storms. Since 1980, Georgia has had over 134 weather disasters that cost over a billion dollars each. A huge chunk of those were severe convective storms—the kind that bring the "green sky" and the sirens in the spring.

Survival Tips for the Fulton Freeze
Since we’re staring down a 35°F night with a snow mix, you’ve gotta do the basics.
- Drip those faucets. If you’re in an older house in Buckhead or Virginia-Highland, those pipes are vulnerable when it hits 26°F on Monday.
- Check the pets. If it’s too cold for you to stand outside in a t-shirt for ten minutes, it’s too cold for them.
- Watch the North-South Divide. Fulton is a long county. The weather in Palmetto is rarely the same as the weather in Johns Creek. If the radar shows "pink" (wintry mix) over Lake Lanier, start heading home if you're up north.
The humidity is going to drop significantly by tomorrow—falling from 89% today to a bone-dry 38% on Sunday. You’re going to feel that in your skin and your sinuses. Grab the moisturizer now.
What to Expect This Spring
January is technically our coldest month, with an average low of 35°F. But honestly, the transition to spring in Fulton is where it gets wild. By March, we’re looking at highs of 66°F, but that’s also our windiest month.
If you're new here, just know that Fulton County GA weather is all about layers. You’ll start the day in a heavy coat, throw it in the backseat by noon, and be looking for a heater by 6:00 PM. It’s just how we live.
Actionable Next Steps:
Check your outdoor spigots today before the temperature drops to 35°F tonight. If you haven't disconnected your garden hoses yet, do it now to prevent a burst pipe when the 20-degree nights hit on Monday and Tuesday.
