So, if you’re living in the Magic City right now, you’ve probably noticed that January is doing exactly what January does best: keeping us guessing. Honestly, trying to pin down a birmingham al weather forecast 15 day outlook is kinda like trying to predict which lane of I-65 is actually going to move during rush hour. One minute you’re enjoying a crisp, sunny afternoon, and the next, you're digging through the hall closet for that heavy parka you swore you wouldn't need this year.
Right now, as we sit on Friday, January 16, 2026, the vibe is definitely "shifting." If you looked out the window earlier today, it was gorgeous—sunny and hitting a high of 58°F. But don't let that fool you. Tonight, a cold front is sliding through, bringing a 98% chance of light rain and dropping the temperature down to a chilly 28°F.
Basically, the "nice" part of the weekend is already packing its bags.
The Cold Truth About Next Week
People often think Alabama winters are just mild, rainy versions of autumn. That’s a mistake. What most people get wrong about the birmingham al weather forecast 15 day trend is the "secondary impulse" factor.

The National Weather Service in Birmingham has been tracking a secondary trough that’s supposed to swing through Saturday night into Sunday. Earlier this week, there was a lot of chatter about a potential wintry mix. You know how it goes—everyone runs to Publix for milk and bread the second someone mentions the "S" word. But the latest data shows that moisture is drying up.
While the far southeastern counties near I-85 might see a stray snowflake or some sleet, Birmingham is looking mostly dry but very, very cold.
- Saturday (Jan 17): Mostly sunny but cooler. High of 51°F, low of 26°F.
- Sunday (Jan 18): Full sun, but you'll feel the bite. High of only 42°F.
- Monday (Jan 19): Partly sunny. High of 48°F. Watch out for a low of 21°F overnight.
That 21°F on Monday night isn't a joke. It’s the kind of cold that makes your tire pressure light pop on for no reason.

Why the Mid-Range Forecast Looks Messy
If you're looking further out toward the end of January, things get a bit more "classic Alabama." By Wednesday, January 21, we start climbing back up into the 50s, but that warmth usually comes with a price tag: rain.
There's a system shaping up for next Thursday, January 22, that looks like a messy mix of rain and potentially some light snow as the temperatures hover right around 50°F during the day and drop to 36°F at night. It’s that awkward temperature range where it's too warm for a snow day but too cold to actually enjoy being outside.
Breaking Down the Averages
Historically, Birmingham in January averages a high of 53°F and a low of 33°F. We are currently trending just a bit below those normals for the next week.

According to data from groups like the Alabama Emergency Management Agency, the real threat this time of year isn't always the snow—it’s the flash freezes and the rapid shifts in humidity. We’re looking at humidity levels jumping from a dry 36% today to a damp 80% by the following Sunday. That "damp cold" is what actually gets into your bones.
What You Should Actually Do
Stop checking the app every thirty minutes. These 15-day outlooks are great for "vibes," but the physics of the atmosphere over the Appalachian foothills means things change fast.
- Drip the pipes Monday night. With a low of 21°F, those exterior walls are going to get icy.
- Check your tires now. That 30-degree swing between today and tomorrow morning will tank your PSI.
- Prepare for a "gray" week. After the sun leaves us on Tuesday, Jan 20, we’re looking at a stretch of cloudy, drizzly days through the 25th.
The end of the month—around January 26—shows signs of clearing up with highs returning to the upper 40s. It’s not exactly tropical, but it’s manageable. Just remember that in Birmingham, "winter" is usually just a series of three-day cold snaps separated by rainy Tuesdays.
Keep your layers handy and don't pack away the umbrella just because it's freezing. In Alabama, it can absolutely do both at the same time.
