Early Winter Snow Blankets Northern Rockies

Winter has arrived early across Montana and the Northern Rockies, with heavy snow and rain blanketing the region through Wednesday. The winter weather is attributed to the remnants of former Tropical Storm Rachel moving across the area.

As Rachel's remnants continue eastward, a deep dip in the jet stream is pulling colder air into the West, prompting snowfall across the central and southern Rockies. This cold air is pushing south, leading to snow accumulation in the higher elevations of Wyoming, Utah, and Colorado.

The Wasatch Range in Utah and the western and central slopes of Colorado are expected to see the heaviest snowfall, particularly on high-elevation passes and mountain peaks. Elevations above 8,000 feet could receive an additional 8 to 12 inches of snow, with some peaks potentially seeing up to a foot.

The winter weather system is forecast to diminish by late Wednesday morning, leaving behind isolated mountain flurries as the trough weakens and moves east across the Plains.

This early-October snowfall could offer a beneficial boost for ski resorts in the West, aiming to recover from a challenging and dry 2025-2026 winter season. Data from Inntopia DestiMetrics indicated a 5.6% decrease in lodging occupancy rates for November through February across 17 mountain destinations in Colorado, Utah, California, Nevada, Wyoming, Montana, and Idaho, according to Travel Weekly.

Last season, many ski resorts experienced early closures due to a lack of snow and unseasonably warm temperatures. Widespread snow drought conditions affected much of the Intermountain West and Northern Rockies, influenced by persistent warm weather and a weakened northern storm track. Numerous areas recorded snowfall totals among their lowest on record, resulting in significantly below-average snowpack levels.

Looking ahead, a potentially strong Super El Niño could influence this winter's weather patterns. El Niño's effects can vary across the U.S., with a more active Pacific jet stream potentially directing storms towards California and the Southwest, which could lead to increased snowfall at higher elevations in the Sierra Nevada and Southern Rockies.
