You’ve probably heard the jokes about Mississippi weather. If you don't like it, just wait five minutes, right? Honestly, there is a lot of truth to that, especially when you are looking at the tupelo ms weather forecast in the dead of winter. It is 2026, and while we have better satellites and fancier models, Northeast Mississippi still loves to throw a curveball that catches people off guard.
Most folks from out of town expect the Deep South to be balmy year-round. They pack a light sweater and call it a day. Then they step off the plane at Tupelo Regional Airport and realize the "humid subtropical" label is a bit of a trick in January. It’s cold. Not "Chicago blizzard" cold, but a damp, bone-chilling cold that finds the gaps in your coat.
The Reality of Right Now in Tupelo
Today, Saturday, January 17, 2026, is a perfect example of how Tupelo plays with your expectations. If you looked out the window earlier, you saw a bit of sun. But don't let the "partly sunny" label fool you. The current temperature is sitting right at 45°F, and with a northwest wind cutting through at 10 mph, it actually feels more like 40°F.

That wind is the real kicker. It’s coming from the northwest, which in this part of the state usually means dry air is trying to shove out the morning clouds. Humidity is at 53%, which is actually quite low for us. Usually, we’re swimming in moisture, but today is a bit crisper.
What the Rest of the Day Looks Like
If you’re planning on heading out to the Natchez Trace or grabbing a burger downtown, keep the heavy layers handy. The high for today is only hitting 46°F. We are basically at the peak right now. As the sun starts to dip, things are going to get interesting.
The sky is going to stay mostly cloudy for a good chunk of the afternoon. There’s a tiny 10% chance of some light precipitation. Now, here’s the weird part of the tupelo ms weather forecast today: if anything falls, it might actually be a stray snow flurry. It’s not going to stick—don't go buying out the milk and bread at Kroger—but it’s a reminder that we are in the heart of winter.

Tonight’s Deep Freeze
Once the sun goes down, the clouds are actually expected to clear out. Usually, that’s a good thing, but in the winter, clear skies mean all our heat escapes into the atmosphere.
- The low tonight is dropping to 23°F.
- Northwest winds will pick up slightly to 12 mph.
- The UV index will be a 3 during the peak hours, which is low, but still enough to catch a glare if you’re driving west on Main Street.
Basically, if you have outdoor pipes that aren't insulated or sensitive plants sitting on the porch, tonight is the night to take care of them. A drop to 23 degrees is a "hard freeze" territory for Mississippi.
Why Tupelo Weather Is So Unpredictable
Tupelo sits in a weird geographical spot. We are far enough north that we get the tail end of those Arctic blasts coming down through the plains, but we’re far enough south that we’re constantly fighting with moisture from the Gulf of Mexico. When those two meet, you get the legendary Mississippi ice storms or the sudden 30-degree temperature swings.
Historically, January is our coldest month. While our average highs are usually in the low 50s, 2026 has been a bit more volatile. Just a few days ago, we were seeing much milder temperatures, but this current "frigid blast" (as some of the local meteorologists are calling it) is a reminder of why you can't trust a forecast more than three days out.
Actionable Steps for the Weekend
Since we are looking at a high of 46°F and a low of 23°F, you need to be smart about the next 24 hours. Honestly, it's just about common sense, but the South sometimes forgets how to handle the teens and twenties.
First, check your tire pressure. Sudden drops in temperature like we're seeing today will trigger that annoying "low pressure" light on your dashboard. Second, if you’re heading out tonight, the wind chill is going to make that 23 degrees feel significantly colder. Northwest winds at 12 mph are no joke when the sun is down. Wear a hat. Most of your heat escapes through your head, and in this wind, you'll feel it instantly.
Finally, keep an eye on the sky. That 10% chance of snow is low, but in Northeast Mississippi, "low chance" doesn't mean "no chance." It just means it'll be a surprise. Stay warm, keep the pets inside, and enjoy the clear (but freezing) Saturday night.
