12 inches of snow expected in Rockies as rare late-June storm hits: National Weather Service

Image for 12 inches of snow expected in Rockies as rare late-June storm hits: National Weather Service

Imagine packing for the 4th of July

And needing tire chains.

Blankets.

A flashlight.

Just in case you get stranded in a snowdrift.

That's the reality unfolding right now across the northern Rockies.


❄️ Winter just gatecrashed June

A rare late-June winter storm is dumping serious snow across Montana, Idaho and Wyoming.

Not a dusting. Not a flurry.

👉 Up to 12 inches at the highest peaks.

The National Weather Service has lit up the map with Winter Storm Warnings and Winter Weather Advisories — in the same week Americans are firing up grills for Independence Day.


🌡️ The numbers are wild

A deep upper-level trough is yanking arctic air straight into the Rockies, and the forecast reads like January cosplay:

  • 🥶 Temps 15–20°F below seasonal averages
  • 🏔️ 4–8 inches of snow around Georgetown Lake, MT (12 at peaks)
  • ⛰️ Up to 6 inches on Idaho's Fourth of July peak (you can't make this up)
  • 🌨️ 4–6 inches across higher elevations in Wyoming
  • 💨 Wind gusts topping 50 mph in north-central Montana

Sunday, June 28, is shaping up to be the coldest day of the entire stretch.

Some towns are flirting with daily record lows.


🚧 And the timing couldn't be worse

This is peak road-trip season.

Glacier. Yellowstone. The Tetons.

Millions of travelers headed straight into the mountains for the holiday week.

Instead, they're getting:

  • 🛻 Blocked mountain passes
  • 🌲 Downed trees from heavy, wet snow
  • ⚡ Scattered thunderstorms
  • 🌊 Flash flood risk around Glacier National Park
  • 🩺 Real hypothermia danger in the backcountry

The NWS message is blunt: delay travel through mountain passes if you can.


🧠 The bigger picture

June snow in the Rockies isn't unheard of.

But a foot of it, paired with record-chasing cold and 50 mph winds, days before July?

That's the kind of weather whiplash that's becoming the new normal.

One half of America is baking under a heat dome.

The other half is shoveling.

Same country. Same week. Different planet.


⚡ Final thought

Fireworks on one side of the map.

Snowplows on the other.

Welcome to summer in 2026.

That's all for now!
