Arkansas weather is a moody teenager. One minute it’s sun-drenched and hopeful, the next it’s throwing a freezing tantrum that shuts down Highway 67. If you’ve lived in Lonoke County for more than a week, you know the "layers" talk isn't just a suggestion—it’s a survival strategy.
Honestly, the Cabot AR weather forecast right now is a perfect example of why you can't trust a clear sky. As of Sunday night, January 18, 2026, it is a crisp 33°F outside. The sky is clear, which sounds nice until you realize that without cloud cover, the heat is escaping into space like an open window in a drafty house. It actually feels like 28°F.
That 5-degree difference is the gap between "I'll just run to the mailbox in my slippers" and "I need a podiatrist because my toes are numb."

The Immediate Outlook: Cold, Dry, and Deceptive
If you're looking at the numbers for the rest of tonight, don't get comfortable. We're heading toward a low of 19°F. That is deep-freeze territory. Humidity is sitting low at 30%, so it's that "dry cold" that makes your knuckles crack and your static electricity reach superhero levels.
Tomorrow, Monday, isn't going to be a tropical getaway either. We’re looking at a high of about 38°F. Sunny? Yes. Warm? Absolutely not. With a southwest wind moving at 10 mph, that sun is mostly decorative.
- Tonight's Low: 19°F (Clear)
- Monday's High: 38°F (Sunny)
- Wind: Southwest at 10 mph
- Precipitation Chance: Basically 0% (Snow isn't invited yet)
Why Cabot Weather Hits Differently
People from the North love to mock Arkansans when we freak out over a 30-degree day. But they don't get the humidity factor. Even in January, our "dry" days are often heavier than what you'd see in the high desert. Plus, Cabot sits in a spot where the wind can really whip across the flatter farmland surrounding the city, making that 10 mph gust feel like it's slicing right through a fleece jacket.
Historically, January 16 is usually our "coldest" day, so we are right in the thick of it. The average high this time of year is typically 50°F, but we are currently trailing well below that. We're in a bit of a cold snap, even by local standards.
The Mid-Week "Switch-Up"
Don't get used to the dry air. By Wednesday, things start to get weird. The forecast is hinting at a shift toward overcast skies and a significant jump in humidity. While we aren't seeing a massive "Snowmageddon" on the immediate horizon for this specific week, the transition from clear/cold to cloudy/wet is when the Cabot "black ice" special usually makes its debut on the bridge overpasses.
Surviving the Cabot Deep Freeze
Since we’re staring down a 19°F night, you've gotta do the boring adult stuff.

- The 3 P's: Pipes, Plants, and Pets. If your pipes are on an exterior wall, let them drip. Your hibiscus is already dead if it's still outside, but save the others.
- Tire Pressure: Cold air makes your tires look flat. Don't panic; it’s just physics. Check your PSI before you head to Little Rock for work tomorrow.
- Black Ice Watch: Even with 0% precipitation, "flash freezes" of morning dew on the overpasses near the 167 interchange are real.
The Cabot AR weather forecast shows a UV index of 2 for tomorrow. It's low, but if you're outside for a long time, the reflection off the frost can still bite. Wear the sunglasses. You’ll look cooler anyway.
Basically, stay inside if you can. If you can’t, keep a blanket in the trunk. It’s Arkansas; the weather might change its mind by Tuesday, but tonight, it’s decided to be a refrigerator.
Actionable Next Steps:
Check your outdoor faucet covers tonight before the temperature hits that 19°F low. If you’re commuting Monday morning, give yourself an extra 10 minutes for the car to defrost—scraping a windshield with a credit card at 6:00 AM is a lifestyle choice nobody actually wants.
