If you’ve lived in Nebraska for more than five minutes, you know the drill. You wake up, check the window, and wonder if you need a parka or just a light hoodie. Honestly, this week is basically a masterclass in Great Plains mood swings. We are currently staring down an Omaha 7 day weather forecast that looks more like a heart rate monitor than a seasonal trend.
Right now, as of Sunday, January 18, 2026, it’s a crisp 7°F outside. But "crisp" is being generous. With the wind coming out of the south at 7 mph, the "feels like" temperature is sitting at a biting -4°F. If you’re heading out to grab coffee, just know that exposed skin is going to regret it pretty quickly.
But here is the kicker: by this afternoon, we’re actually aiming for a high of 32°F. That is a 25-degree jump in a few hours. Welcome to winter in Omaha.
The Immediate Outlook: Winds and Wind Chills
Sunday isn’t just about the cold; it’s about the movement. The National Weather Service has already flagged a Wind Advisory effective until 7:00 PM tonight. We’re expecting northwest winds to ramp up to 21 mph, with some gusts potentially hitting the 40 mph mark.
- Sunday Night: The mercury drops fast. We’re looking at a low of 3°F or 4°F depending on which side of Dodge Street you're on.
- Monday (MLK Day): It’s going to be a struggle. Highs will only reach about 18°F under partly sunny skies.
- The "Biting" Factor: Wind chills on Monday morning could easily hover between 5 and 20 degrees below zero. If you're planning on attending any Martin Luther King Jr. Day events outdoors, layers aren't optional—they’re survival.
Mid-Week Tease: The 30s Return
Just when you think we’re settling into a deep freeze, the atmosphere shifts. Tuesday and Wednesday are looking like the "balmy" spots of the week.

On Tuesday, January 20, we climb back up to 36°F. It’ll be cloudy, sure, but that 36 feels like a tropical vacation compared to Monday's sub-zero wind chills. By Wednesday, we might even hit 38°F.
There is a 35% chance of light snow during the day on Wednesday. This isn't likely to be a "shovels out" kind of event, but more of a "slow down on I-80" dusting. The wind will be back too, puffing out of the west at 19 mph, which keeps the air feeling much sharper than the thermometer suggests.
Why Omaha Weather Is This Chaotic in 2026
You might be wondering why we can't just have a normal, consistent winter. The answer lies in the fading La Niña. According to meteorologists at DTN and the Nebraska State Climate Office, we’re transitioning into an ENSO-neutral phase as we head toward spring 2026.
When the Pacific Ocean is in this "in-between" state, the jet stream becomes a bit of a chaotic live wire. Instead of a steady flow of air, we get "clipper systems"—fast-moving disturbances that dive down from Canada. They bring a quick burst of clouds or light snow, a sharp drop in temperature, and then they vanish just as quickly as they arrived. That is exactly what’s driving the Omaha 7 day weather forecast right now.

Heading Into the Weekend: Another Deep Dive
Enjoy that mid-week "warmth" while it lasts. Thursday holds steady at 39°F, which will likely be the peak of the week. After that, the floor drops out again.
- Friday, Jan 23: Highs retreat to 27°F as a northeast wind brings in more Canadian air.
- Saturday, Jan 24: We hit the true bottom of the 7-day cycle. A high of only 8°F and a low of 1°F or 2°F.
- Precipitation: While the chance of snow stays around 10% for most of the late week, these cold snaps often squeeze every bit of moisture out of the air. Don't be surprised by "diamond dust" or lingering flurries that don't show up on the radar.
Real Talk on E-E-A-T: Trusting the Data
When you're looking at a forecast this far out, remember that Great Plains meteorology is an evolving science. Experts like Dr. Martha Shulski at the Nebraska State Climate Office often point out that while we can predict the pattern (the roller coaster), the exact timing of a cold front can shift by 6 to 12 hours.
The current data comes from the Eppley Airfield (KOMA) sensors and the NWS Valley office. These are the "gold standard" for local accuracy. If you see a national app telling you it's going to be 45 degrees next Saturday, take it with a massive grain of road salt. The local signals are leaning much colder.
How to Handle This Week
Basically, don't pack away the heavy gear just because Tuesday looks decent. The temperature swing from Thursday (39°F) to Saturday (8°F) is a 31-degree crash. That kind of change can put a lot of stress on your home's HVAC system and your car battery.

Actionable Steps for Omahans:
- Battery Check: If your car battery is more than three years old, Saturday’s 1°F low will be its biggest test. Get it tested Monday or Tuesday while the weather is mild.
- Pipe Protection: When we hit those single-digit nights on Friday and Saturday, make sure your outdoor hoses are disconnected. If you have a room that stays notoriously cold, open the cabinet doors to let warm air reach the pipes.
- Layering Logic: This week is about the "base layer." Wear moisture-wicking materials on Wednesday when that 35% snow chance hits, as damp clothes in 20-mph winds are a recipe for hypothermia.
This isn't the year's worst blizzard, and it’s not a record-breaking heatwave. It’s just January in Omaha—fickle, windy, and keeping everyone on their toes.
Next Steps:
Check your tire pressure today. Those 30-degree temperature drops cause air to compress, which usually triggers that annoying "low tire" light right when you're already running late for work on a Monday morning.
