Honestly, people think Reno is just "Vegas but colder" or "Lake Tahoe’s driveway." But if you’re looking at the reno nv weather 15 day forecast right now, you’re seeing the weird reality of the high desert. It’s Saturday, January 17, 2026, and while the rest of the country is arguably losing its mind over mid-winter blizzards, we’re sitting here in a "January Thaw."
The current temperature is a crisp 39°F. Sounds cold? For Reno in January, it’s basically t-shirt weather if the sun is hitting you right. We’ve got a massive high-pressure ridge parked over the Eastern Pacific and the Western US, which is essentially acting like a giant umbrella, pushing all the nasty storms north or south of us.
The 15-Day Reality Check
If you're planning a trip or just trying to figure out if you need to drain your pipes, the next two weeks are going to be a bit of a psychological rollercoaster.
We are currently trapped in a classic valley inversion. That’s a fancy way of saying the cold air is stuck on the floor of the Truckee Meadows while the mountains are actually warmer. It makes the sky look hazy and kind of gross because all the fireplace smoke and car exhaust has nowhere to go. Today, Saturday the 17th, we’re looking at a high of 46°F and a low of 27°F. Expect it to stay pretty stagnant through the weekend.
What the Next Two Weeks Look Like
- The Immediate Stretch (Jan 18–24): It’s going to stay dry. Highs will hover between 48°F and 57°F. You’ll see a lot of "Mostly Sunny" or "Few Clouds" on your weather app. Tuesday and Wednesday (Jan 20-21) look particularly nice with highs hitting 51°F and 53°F respectively.
- The Humidity Factor: Don't let the 41% humidity fool you. It’s dry. Your skin will crack. Your nose will bleed. Drink more water than you think you need.
- The Turning Point (Jan 25 and beyond): This is where it gets interesting. Historically, and according to the long-range models from the Almanac and NWS, the end of January is when the "Sunny and Mild" vibes start to crumble. We’re expecting a shift back to colder, more unsettled weather. The snowiest periods for 2026 are predicted for late January and early February.
Basically, enjoy the 50-degree afternoons while they last, because a cold snap is lurking right around the corner.

Why Reno Weather is Never "Simple"
The "Rain Shadow" is the boss here. The Sierra Nevada mountains to our west act like a giant sponge, wringing out all the moisture from Pacific storms before they reach us. That’s why you can see 4 feet of snow in Truckee and literally zero in downtown Reno.
But sometimes, we get the "Lake Effect." If a storm passes over Lake Tahoe just right, it picks up extra moisture and dumps it directly on us. It’s unpredictable and makes the reno nv weather 15 day outlook a bit of a gambling game.

Winter Driving: Don't Be That Person
If the forecast holds and we stay dry for the next week, the roads will be clear. But "clear" doesn't mean "safe."
- Black Ice: Shady spots and bridge decks freeze first. Even if it's 40°F out, that corner near the river might be a skating rink.
- Inversion Fog: Patchy freezing fog is a real threat in the valleys right now. If you can't see, slow down.
- Mountain Passes: If you're heading over I-80 to Cali, ignore the Reno sun. The pass is a different world. Always carry chains. It’s 2026—Caltrans isn't getting any more patient with people blocking the road because they thought their AWD SUV was invincible.
Actionable Next Steps
If you are tracking the reno nv weather 15 day trend, here is what you should actually do:
- Seal the gaps. Check your door sweeps and window seals now while it’s 50°F out. When the late-January cold hits, you’ll be glad you did.
- Prep the car. Make sure your washer fluid is the de-icer kind (rated for sub-zero). Regular fluid will freeze and crack your reservoir the second the sun goes down.
- Check the 511. In Nevada, dial 511 or check nvroads.com before you head out. Things change fast when the high-pressure ridge breaks.
- Moisturize. No, seriously. Buy a humidifier for your bedroom. The 30-40% humidity range we’re seeing right now is brutal on your respiratory system.
The "January Thaw" is a gift. Use the next 10 days of dry, mild weather to get your life in order before the Sierra starts acting up again in February.
