Honestly, if you stepped outside in Casper this morning, you probably noticed something felt off. It’s mid-January. We should be shivering in our heaviest Carhartt jackets, dodging ice patches on Wyoming Boulevard. Instead, the air has this strange, mild bite to it that feels more like late March than the dead of winter.
The forecast for Casper Wyoming right now is basically a glitch in the Matrix. While the rest of the country expects Wyoming to be a frozen tundra this time of year, we’re sitting here with highs that are pushing 20 degrees above the seasonal norm.
It’s weird. It’s windy. It’s Casper.
The Short-Term Outlook: Sunglasses and Windbreakers
Today, Tuesday, January 13, 2026, we’re looking at a high near 51°F. That is not a typo. For a city where the average January high is usually closer to 35°F, hitting the fifties is a massive swing. The sky is staying mostly cloudy, which keeps that warmth trapped near the ground, but don't let the "balmy" air fool you into thinking it's a calm day.

West winds are sustained at 18 mph, and if you’ve lived here for more than a week, you know what that means for high-profile vehicles. The National Weather Service has already flagged some "Extreme Blow Over Risk" zones, specifically on WY 251 and parts of WY 258. Basically, if you're driving a light trailer or a high-profile van, you might want to wait until the gusts settle.
Tonight, things stay relatively mild with a low of 38°F, but keep an eye on the sky. There’s a slight chance of some stray snow showers moving in late, though with these ground temperatures, nothing is really going to stick yet.
The Week Ahead: A Slow Slide Back to Reality
Enjoy the warmth while it lasts because the thermometer is about to take a dip. Tomorrow, Wednesday, January 14, looks like the peak of this little heat wave with a high of 52°F and plenty of sunshine.

- Thursday, Jan 15: The sun stays out, but the temperature drops to 45°F.

- The Weekend: Saturday and Sunday see a slight rebound into the 30s, but those overnight lows will be biting, dipping down to 16°F by Sunday night.
Why Casper Isn't Underwater (or Under Snow) Right Now
You might be hearing about the "Teton Trickle" over in Jackson—that endless cycle of mountain snow that keeps the ski resorts happy. But here east of the Divide, we’re in a different world.
Meteorologist Don Day has been talking about this "ENSO neutral" pattern for the 2025-2026 season. It's a fancy way of saying neither El Niño nor La Niña is totally in charge. This leads to what we're seeing: "ups and downs" rather than one long, sustained polar vortex. We get these weirdly warm weeks followed by sharp, sudden snowstorms.
Historically, January is actually our driest month. We only average about 0.49 inches of precipitation. The big, heavy, wet snows that Casper is famous for usually don't hit until March or April. So, while the brown grass looks depressing, it’s actually pretty normal for the high plains this time of year.

Surviving the "Windy City" Transitions
The real danger in Casper isn't usually the cold; it's the variability. When the temperature swings 30 degrees in 24 hours, the roads turn into a skating rink. WYDOT is already reporting "slick in spots" on WY 220 between Casper and Alcova.
If you're planning a trip out toward Muddy Mountain or just heading to the Eastridge Mall, remember that a 50-degree day can still have black ice in the shadows.
Actionable Next Steps for Casper Residents:
- Check your tires now: The drop from 52°F on Wednesday to 29°F on Friday will cause your tire pressure to plummet. Don't wait for the light to come on.
- Secure the patio furniture: Those west winds at 18-24 mph are enough to send a plastic chair into your neighbor's yard.
- Hydrate: We’re at 5,150 feet. Even when it’s cloudy and cool, the dry air here saps moisture out of you faster than you realize.
- Monitor WYDOT: Before heading out of town, check the sensors for "Extreme Blow Over" warnings, especially if you're heading toward Hat Six or Outer Drive.
Winter in Casper is never a straight line. It's a jagged, windy, unpredictable mess—and that’s exactly what the next seven days have in store.
