Updated Storm Timeline — Utah & Colorado Today – Tuesday, November 3
Halloween: Calm before the storm
Alta / Snowbird / Brighton: A relative break in precipitation today, with clouds and occasional light snow showers possible at upper elevations.
Southern Colorado — Wolf Creek / Telluride / Silverton: A few scattered showers early, followed by a generally quieter afternoon and evening. Snow levels remain high, so much of the precipitation below the highest peaks could fall as rain.
SUN — The AR (atmospheric river) arrives!
Alta / Snowbird / Brighton: Precipitation increases as a powerful AR and Pacific trough moves into Utah. Initially high snow levels should begin falling as the cold front approaches. The best snow hits Sunday night.
San Juans: Heavy precipitation hits the San Juans but there’s a catch: snow levels remain high through much of Sunday, meaning significant rain is possible at lower elevations. Snow levels begin falling Sunday night, setting the stage for heavy, wet snow.
Divide Resorts: Snow chances increase late Sunday, particularly above 8,500 feet. The exact track of the upper-level system remains important, but confidence is increasing that the high mountains will receive good snow.
MON — The S..t hits the fan! Peak snowfall potential–still
Cotonwoods: The heaviest accumulating snow is favored Sunday night into early Monday as colder air moves across the Wasatch. Some spots could see a foot of new snow.
Wolf Creek / Telluride / Silverton: This should be the big day for the San Juans! As the cold front pushes through, rain transitions to snow at progressively lower elevations. Heavy, wet snowfall is possible, particularly above 10,000 feet, with over a foot possible.
Divide Resorts: Monday looks like the primary snowfall day. Colder temperatures, stronger lift, and favorable mountain elevations should support accumulating snow.
TUE — Storm exits, colder air remains
Wolf Creek / Telluride / Silverton: Lingering mountain snow showers remain possible, particularly early, before precipitation gradually diminishes.
A-Basin / Loveland / Summit County: Lingering snow showers are possible early, especially if the system moves more slowly.
FutureSnow takeaway: The moisture is coming. The key question is how much falls as snow before the storm exits. Sunday night through Monday remains the most important period, particularly for the Cottonwoods and the higher elevations of the San Juans.
Big News! FutureSnow Is Teaming Up with Rocky Mountain Sled Conditions! What if you could identify the next big snowstorm weeks before it arrives? Know when to be “sick” or take time off?
For those who haven’t heard of us, FutureSnow is a weather forecasting service that specializes in something a little different: predicting when significant winter storms may occur 30 to 60 days in advance.
While traditional weather forecasts focus primarily on the next several days, we cover that of course, but we look much farther down the road.
How Is That Possible? Our forecasting approach is based on a fascinating characteristic of the atmosphere: wave patterns cycle and repeat.
By identifying these patterns and tracking how they evolve, we forecast when favorable storm setups return weeks and even months later.
The storms won’t necessarily be identical. Their strength, location, and snowfall amounts can change. But recognizing the recurring atmospheric setup can provide valuable clues about future storm opportunities.
Our Track Record
FutureSnow has been making and documenting long-range storm predictions for years.
In one of our published evaluations, we recorded nearly 90% accuracy in identifying predicted snowstorm events, with an average forecast lead time of 36 days within a day of the forecasted storm.
Long-range forecasting is never perfect, and these results represent our own historical verification. But they demonstrate why we believe there is tremendous potential in studying recurring weather patterns.
What Does This Mean for Snowmobilers?
Imagine being able to identify a potential major storm window in the Snowy Range, Rabbit Ears Pass, Togwotee, or the mountains of Montana and Idaho several weeks ahead of time.
Instead of choosing your trip dates and hoping the snow cooperates, you could use our long-range forecasts to help identify promising opportunities before making your plans.
And as those dates approach, we’ll follow the latest weather models to refine the forecast.
RMSC will continue providing the detailed snow conditions, interactive maps, and riding-area information you already rely on. FutureSnow will bring an additional long-range perspective to help you look farther ahead.
What we will be Sharing This Winter
Throughout the season, we’ll share weather discussions, upcoming storm forecasts, projected snowfall, and insights into the evolving winter pattern with the RMSC community.
