You’ve felt it, right? That sudden, bone-chilling shift where the air just bites at your face the second you step out of the garage. One minute we're cruising through a relatively mild Georgia winter, and the next, everyone in Alpharetta is frantically checking their weather apps every fifteen minutes. Honestly, it’s kinda the local pastime lately.
If you’re looking at the Alpharetta 10 day forecast, it’s a bit of a rollercoaster. We aren't just talking about a little frost on the windshield. It’s the kind of weather where you actually have to remember where you stashed the heavy-duty wool socks.
The Immediate Outlook: Sun Without the Heat
Right now, Alpharetta is sitting at a crisp 38°F.
Don't let the "sunny" description fool you when you look out the window. With a northwest wind kicking at 13 mph, the real-feel temperature is hovering right around 30°F. It’s bright, it’s blue, and it’s deceptive as heck.
Today, Sunday, January 18, we’re looking at a high of 38°F and a low of 28°F. There’s a tiny 10% chance of snow during the day, which basically means you might see a stray flake if you stare at the sky long enough, but don’t expect to go sledding down the hills at Wills Park just yet.
Monday and Tuesday: Bracing for the Freeze
Monday, January 19, actually looks decent on paper. We’ll hit 42°F, but the night is going to be brutal. We're dropping down to 24°F.

If you have sensitive plants or pipes that like to act up, this is your warning.
Tuesday stays in that "stay inside and drink tea" range with a high of 39°F and a low of 22°F. It’s going to be exceptionally dry too, with humidity crashing down to 30%. Your skin is probably already feeling that tightness, so maybe double up on the moisturizer.
Mid-Week Shifts and Growing Clouds
By Wednesday, January 21, the pattern starts to shift. The sun takes a backseat to the clouds.
- Wednesday: High of 47°F, low of 26°F. Cloudy all day.
- Thursday: A brief jump to 52°F. It might actually feel like winter in the South instead of the Arctic for a few hours.
- Friday: We’re back to cloudy skies, with a high of 51°F and a 25% chance of light rain overnight.
It's that weird transition period where the air feels "heavy." You know the feeling. It's not quite raining, but everything feels damp and the cold seems to settle into your bones more than when it's just dry and freezing.
The 10-Day Horizon: Rain, Snow, and More Rain
The weekend of January 24 and 25 is looking pretty messy.

Saturday brings light rain throughout the day with a high of 53°F. Sunday cools down significantly to 44°F, and that rain isn't going anywhere.
But here is where the Alpharetta 10 day forecast gets really interesting for the weather nerds.
On Monday, January 26, we have a 65% chance of rain and a high of 50°F. But look at the humidity—it's pegged at 100%. Then, as we move into Tuesday and Wednesday (January 27-28), we see the return of the "winter mix." We’re talking rain and snow combinations with highs in the low 40s and lows hitting 30°F.
Basically, it's going to be a slushy, grey mess.
Why Alpharetta Weather Is So Hard to Predict
Our local geography plays a huge role. Being just north of Atlanta and sitting in the foothills, we often get caught in that "wedge" of cold air that gets trapped against the mountains.

Meteorologists like those at the National Weather Service in Peachtree City often talk about how a five-mile shift in a storm track can mean the difference between a rainy afternoon and a city-wide shutdown.
What You Should Actually Do About It
Forget the "bread and milk" panic. That's for amateurs. If you’re living through this 10-day stretch, here’s the real-world checklist:
- Check your tire pressure. These 20-degree drops in temperature will make your "low pressure" light pop up faster than a notification on your phone.
- The 3 PM Window. Between Wednesday and Thursday, that’s your best bet for outdoor errands. It’s the only time the temps will be above 50 without active rain.
- Watch the Monday commute. With a 65% rain chance on January 26 followed by a drop to 32°F, black ice on those side roads near Windward is a very real possibility.
- Pet Safety. If it’s too cold for you to stand outside in a t-shirt for five minutes, it’s too cold for your dog to be out there all night. Bring 'em in.
This January is definitely making its presence felt. Whether you're heading to Avalon for some shopping or just trying to get through the work week, keep an eye on those Tuesday and Wednesday overnight lows. They’re the real story here.
Stay warm, keep the pipes dripping on those 22-degree nights, and maybe keep an extra scraper in the car. You're going to need it.
Actionable Next Steps:
Check your outdoor spigots today before the temperature drops to 24°F on Monday night. If you haven't covered them yet, use an insulated cover or even a thick towel secured with duct tape to prevent freezing. Tonight (Sunday) is the last night of relatively "mild" 28-degree weather before the deeper freeze hits.**
