Honestly, living in North Alabama feels like a game of weather roulette most weeks. You wake up on a Thursday morning like today, January 15, 2026, and the sun is blinding. It's beautiful, but it's 36 degrees and the wind is coming out of the northwest at 11 mph, making it feel like 28. Basically, don't let the clear skies fool you; it's a "heavy coat and scarf" kind of morning.
But here is where the 7 day forecast Huntsville AL gets weird. If you’ve lived here long enough, you know the Tennessee Valley has its own personality. We aren't just looking at a straight line of cold. We’ve got a mix of sunshine, a "blink and you'll miss it" rain-snow chance, and a plummeting thermometer that might catch you off guard if you're planning for the weekend.
The Next 48 Hours: The Warmth Before the "What Was That?"
Friday is looking like the standout day for anyone who hates the deep freeze. We're actually going to hit a high of 49°F tomorrow, Jan 16. That sounds great, right? Well, sort of. While it’s warmer, the humidity is going to climb to about 47%, and by Friday night, things get messy.
We are looking at a 65% chance of precipitation Friday night. Now, the official read is "snow type," but with a low of 30°F, it’s that classic Alabama slushy mix that makes the Parkway a nightmare.

Saturday (Jan 17) clears up slightly with a high of 43°F, but the wind is going to kick up to 13 mph from the west. If you’re heading to the Trash Pandas stadium for a winter event or just hitting up Lowe Mill, keep in mind that the wind chill is going to be the real story. By Saturday night, we drop to a bone-chilling 22°F.
Deep Freeze for MLK Day
Sunday and Monday are basically copies of each other, just with different levels of "ouch."
- Sunday, Jan 18: Sunny skies, high of 36°F, low of 23°F. It’s crisp and dry.
- Monday, Jan 19 (MLK Day): Still sunny, slightly warmer at 40°F, but the overnight low is a brutal 18°F.
If you’re participating in any MLK Day marches or outdoor service projects, you’ve got to layer up. The humidity drops to 43% on Monday, so it’s a very dry cold. Your skin is going to hate it.

Huntsville Weather: What the 7 Day Forecast Doesn't Tell You
Look, the National Weather Service in Huntsville is great, but there’s a nuance to our local climate. We are tucked into a valley. That means when the cold air sinks, it stays.
Tuesday, Jan 20, is actually going to be our coldest daytime high of the week at just 35°F. Even with full sun, the "periodic clouds" moving in Tuesday night aren't going to act like a blanket; they're just there for decoration as we hit 20°F again.
Midweek Shakeup: Rain Returns
By Wednesday, Jan 21, the pattern breaks. We start seeing a shift in the wind—it moves to the south at 10 mph. This brings in moisture. You’ll feel the air get "heavy" again as the high reaches 46°F.

Historical Context: Is This Normal for January?
Actually, yeah. The average high for Huntsville in mid-January is usually around 50°F, but we’ve seen wild swings before. Back in 1985, we hit -11°F. Compared to that, this week is a tropical vacation. But the reason the 7 day forecast Huntsville AL is so important right now is the lack of "staying power" for any one temperature. We are swinging from 35 to 49 and back again.
Staying Prepared in the Rocket City
If you’re new to town or just a lifelong resident who always forgets where the ice scraper is, here’s the deal for the next few days:
Keep your outdoor faucets covered starting Saturday night. That 18-degree low on Monday is the real deal for pipes. Also, if you’re driving Friday night or early Saturday morning, watch the bridges. We have a 65% chance of precipitation, and even a "dusting" of snow in Alabama is enough to make the city stand still.
Check your tire pressure too. These 20-degree drops between day and night will trigger your "low air" light faster than you can grab a coffee at Piper and Leaf. Basically, stay warm, keep the layers handy, and maybe just plan to stay in with some Big Bob Gibson’s leftovers when the mercury hits those teens on Monday night.
