Heavy Snow Looms in the Northern Rockies 10-11-2026 to 10-14-2026

US Snow — The Northern Rockies are in for some snowy weather starting today. We're seeing snow bands forming over Western Montana and into the high terrains of Western Wyoming. This is due to a weather system moving south from Washington and Oregon, bringing moisture, including remnants from a storm named Rachel. Expect snow rates of about 0.5 inches per hour today, increasing to 1 inch per hour tonight in Montana. By Monday, the snow will likely taper off as the system pushes further into California and Nevada. There is a high chance of seeing another 6 inches of snow in the eastern slopes of the Lewis and Flathead Ranges, and significant snowfall is likely in the Wind River Range and the Absarokas in Wyoming.

Sierra Nevada and Nearby Areas

The upper low pressure system is moving into California and Nevada, impacting the Sierra Nevada and other ranges. While light snow is expected on the highest peaks, by Monday, snow levels might drop to 6000 feet as moisture increases. Snow will spread into Utah and Western Colorado with high snow levels around 11,000 feet. The Unitas could see 1-2 feet of snow, with a good chance of more than 8 inches in areas above 9000 feet in Nevada and 10,000 feet in central/southern Utah. Light snow might cover the San Juans in southwest Colorado by Tuesday.

While snowfall is the main concern, significant ice formation is unlikely during this period.
