A late-season snowstorm is forecasted to bring significant snowfall to the Rocky Mountains on May 4, 2026, coinciding with Cinco de Mayo celebrations. Winter Storm Warnings have been issued for parts of Wyoming and Colorado.
Forecasts predict snowfall totals of 10 to 24 inches across the Front Range foothills and Rocky Mountain National Park. Travel conditions are expected to be very difficult to impossible at times, especially late Tuesday.
Key snowfall predictions:
- I-80 between Cheyenne and Laramie is expected to receive 8 to 16 inches of snow from Monday night through Wednesday noon.
- A separate Winter Storm Warning covers Arlington and Elk Mountain along I-80, predicting 5 to 10 inches of snow.
- Cheyenne could see between 4 and 8 inches of total snow accumulation through Wednesday.
Heavy snow will create whiteout conditions with wind gusts up to 45 mph. The storm will exit the area by Wednesday afternoon, leaving behind colder and more wintry conditions.
The historic problem spot is along I-80 west of Rawlins toward Bitter Creek. Drift heights have reached four feet in past storms.
