So, if you’re living in T-Town, you already know the drill: don't like the weather? Wait five minutes. But honestly, the tulsa seven day forecast starting this Sunday, January 18, 2026, is taking that "Oklahoma mood swing" thing to a whole new level. We’re literally looking at a 37-degree swing between Sunday’s high and Monday’s reality check.
It’s wild. Sunday starts off feeling almost like an early spring teaser with a high of 51°F and nothing but sun. But don’t let that fool you into leaving the heavy coat at home for the Monday commute. A cold front is slamming in from the north, dragging our high down to a measly 32°F by tomorrow. Basically, we’re going from light jackets to "why do I live where the wind hurts my face" in less than 24 hours.
What’s Actually Happening This Week
The National Weather Service out of the Tulsa office has been tracking these dry frontal passages, and they're the main reason things feel so erratic. We're stuck in this cycle where south winds warm us up for a day, and then a "dry" front kicks those winds to the north and kills the vibe.

The Mid-Week Rebound
If you can survive the Monday freeze, Tuesday and Wednesday actually look decent. We're bouncing back to the low 50s.
- Tuesday, Jan 20: Sunny and 52°F.
- Wednesday, Jan 21: Mostly clear and 51°F.
It's a classic Oklahoma pattern. The humidity is staying relatively low—around 36% to 40% most days—so it’s that "crisp" cold rather than the damp, bone-chilling kind we sometimes get. You've probably noticed the air feels super dry lately; that's typical for January here, which is historically our driest month. According to climate data from WeatherSpark, we usually only see about 1.3 inches of rain the entire month.

Is Snow Finally Coming?
Everyone’s been asking about the "S" word. Most of this week is bone-dry, but things get interesting toward the weekend. Friday night, January 23, shows a 20% chance of snow showers as the temp drops to 30°F.
By Saturday, January 24, the forecast calls for actual snow showers during the day with a high of only 37°F. Now, 20% isn't exactly a blizzard warning, but it’s enough to make the Saturday morning grocery run a bit more chaotic than usual. The City of Tulsa has already prepped about 9,000 tons of salt for the 2025-2026 season, so the plow crews are definitely on standby.

Dealing with the "Feels Like" Factor
Right now, the actual air temperature is 16°F, but because of that 7 mph south wind, it feels like 6°F. That "feels like" gap is what catches people off guard. When you're looking at the tulsa seven day forecast, always check the wind direction. North winds at 12-15 mph (like what we’re expecting Monday and Wednesday) make a 32-degree day feel more like 20.
Looking Ahead: Actionable Next Steps
The rollercoaster isn't stopping anytime soon, but you can definitely stay ahead of it.
- Sunday Night Prep: Since Monday’s high is only 32°F (and it’s dropping to 21°F at night), tonight is the night to make sure your outdoor faucets are covered.
- The Friday Shift: Keep an eye on the Friday night transition. If you have travel plans for the weekend of the 24th, that 25% chance of snow showers Saturday night could mean some slick spots on the Gilcrease Expressway.
- Layering Strategy: This is a "three-layer" week. Base layer for the 20s in the morning, a removable mid-layer for those 50-degree afternoons, and a wind-resistant shell for the gusty north winds.
The most important thing to remember about the tulsa seven day forecast is that it’s a trend, not a promise. With those northeast winds picking up to 17 mph by Friday, the wind chill is going to be the real story by the time next weekend rolls around.
