Montana Winter Weather Shocker: Snowstorm Targets Mountain Passes in Mid-May!
It may be May, but Montana winter weather isn’t done with us just yet. A Winter Weather Advisory is in effect through 6:00 a.m. Tuesday for parts of southwestern Montana, where up to 6 inches of fresh snow is expected in the mountains. If you’re traveling overnight or early Tuesday, especially through places like Targhee or Raynolds Pass, you could run into slick roads, reduced visibility, and winter-like driving conditions. Yes — winter is making an unexpected comeback.
Where, When, and How Much Snow?
This round of Montana winter weather is targeting higher elevations, particularly the Gallatin and Madison County Mountains and the Centennial Mountains. Popular routes like Big Sky, West Yellowstone, and the nearby passes are in the crosshairs for the heaviest snow. Forecasters expect snow to fall through the night, with the possibility of up to 6 inches piling up before sunrise.
Along with the snow, winds could gust up to 40 mph, which may lead to blowing snow and tricky travel. While folks in the lower valleys will mostly see cold rain or a rain-snow mix, it’s a different story above 6,000 feet — where true winter conditions are back in full force.
What Travelers Need to Know
If you’re hitting the road in or near Montana’s mountain regions, you’ll want to stay alert. Roads could be slick, especially early in the morning before plows have had a chance to clear the snow. Expect slower travel, poor visibility in spots, and delays if snow accumulates faster than expected.
Before heading out, check current road conditions, pack a few basics like blankets and water, and make sure your vehicle is winter-ready — yes, even in mid-May.
When Will It End — and What’s Next?
The good news? This taste of Montana winter weather won’t stick around for long. Snow should taper off by Tuesday morning, and the rest of the week looks drier and warmer. That said, this is a good reminder of how quickly things can change in the mountains. Even in spring, it pays to stay prepared for all types of weather — especially in Big Sky Country.
FAQ About Montana Winter Weather
1. Wait — it’s May! Why is it still snowing in Montana?
We hear you — it definitely feels like we should be done with snow by now. But in Montana, especially up in the mountains, winter doesn’t always stick to the calendar. Places above 6,000 feet can still get snow well into spring. So while the valleys are seeing rain or milder temps, the mountain passes are getting one last blast of winter.
2. Which spots are getting hit by this storm?
The advisory is mainly for the higher elevations in southwestern Montana — that includes the Gallatin and Madison County Mountains, plus the Centennial Mountains. If you’re driving through Targhee Pass, Raynolds Pass, Big Sky, or West Yellowstone, you’re right in the path of the snow.
3. How bad will the roads be?
It depends on where you’re going and when. Overnight into Tuesday morning, mountain roads could be slick and snow-covered, especially before the plows get through. Blowing snow could also make it hard to see. If you don’t have to be out early, it’s a good idea to wait until conditions improve later in the day.
4. When will the snow stop?
The snow should wind down by around 6 a.m. Tuesday. After that, we’re expecting a shift to drier and warmer weather. But don’t let your guard down — roads might still be icy in the early morning, so take it easy if you’re heading out.
5. What’s the smartest way to prep if I need to travel?
Think like it’s January, just in case. Make sure your car is ready for winter driving: good tires, maybe chains if it gets really bad, and an emergency kit with basics like blankets, snacks, water, and a flashlight. Also, check the latest road updates before you leave — a quick look could save you a lot of trouble.
