Colorado is waking up to what may be one of the more dramatic starts to winter in recent years: two storms, arriving back-to-back, are expected to dump heavy snow across the mountains before Halloween.
Forecasts from the National Weather Service (NWS) and the European Centre for Medium‑Range Weather Forecasts show large snow amounts in the high country—more than 20 inches possible in some places. This early shift toward winter weather is on many locals’ minds, especially as ski areas prepare and commuters brace.
First Front Already Flexing its Muscles
The first of the twin storms began strengthening over the weekend, with gusts reaching about 50 mph across the Front Range and mountain terrain. The NWS described the incoming front as “sharp” and noted that a surge of cold air is pushing south-ward, triggering early snow showers around places like Breckenridge, Vail and Steamboat Springs.
Mountain residents and visitors are already sensing winter’s presence, with plumes of snow mixing in and wind whipping across high ridges.
Early Snowmaking Gets Going
Over at Winter Park Resort, crews have kicked their snowmaking machines into gear as natural flakes began falling. “Temperatures dropped in the last 24 hours, creating ideal conditions,” the resort said in a statement.
With the storms approaching, the resort is gearing up for early accumulation—an encouraging sign for winter sports buffs and local businesses alike. It’s a clear signal: winter season may be arriving sooner than many expected.
Big Snow on the Horizon
Forecasters say the second storm—stronger than the first—is expected between Oct. 25–28. Mountain zones could see 8–14 inches of snow, with isolated peaks possibly approaching two feet. That kind of snowfall can rapidly impact travel, mountain access and daily routines.
For communities along the Rockies and high country resorts, the prospect of heavy snow ahead of Halloween is both exciting and sobering as early snow may bring opportunities, but also disruption.
Wind Adds Risk for Near-Blizzard Concerns
It’s not just the snow that has forecasters uneasy—strong winds will be a complicating factor. The NWS hazardous weather outlook warns of gusts in the 35–50 mph range, capable of producing near-blizzard conditions along mountain passes and stretches of Interstate 70.
For drivers, that means suddenly reduced visibility and slick, drifting roads. For residents, it means keeping an eye on updates and possibly altering travel plans.
October’s Weather Swing Sets the Stage
These twin systems arrive at a time when Colorado’s weather has already been on a roller-coaster. A developing La Niña pattern is influencing the West’s October outlook.
According to the National Oceanic and Atmospheric Administration (NOAA), Colorado’s long-range forecast shows near-normal precipitation—but the colder air masses tied to the pattern could magnify early-season snow events. In short: the ingredients are in place for something notable.
Road Crews Ready as Closures Happen
Preparations are well underway and the Colorado Department of Transportation (CDOT) says crews have pre-treated roads and readied snowplows across mountain counties.
On Monday morning, Summit County reported highway closures due to spun-out vehicles and slick surfaces. With storms coming, officials are urging drivers to anticipate delays, carry chains and adjust schedules if heading into the high country.
Front Range Could See its Early Snow
It’s not just the mountains bracing. Residents in Denver, Colorado Springs and other Front Range areas may see measurable snow for the first time this season.
Forecast models show flakes reaching lower elevations as a sharp temperature drop arrives later next week. For many used to milder Octobers, this has the hallmarks of a surprise transition into winter.
Halloween Snow is Historically Rare Here
Snow on Halloween in Denver is unusual. Since 1882, only about 16 percent of Halloweens have recorded any measurable snow, according to NWS data.
If the storm tracks eastward as forecast, this year could buck that trend—and give trick-or-treaters a scene of swirling flakes instead of crisp autumn leaves. Simply put: it’s rare, and worth paying attention to.
Memories of the ’91 Blizzard Linger
The forecast is stirring regional memory of the 1991 Halloween Blizzard, when feet of snow swept parts of the Upper Midwest on Halloween. While forecasters say Colorado’s upcoming storms won’t hit that magnitude, they caution that travel disruptions and hazardous outdoor conditions remain possible.
It’s a reminder that even when the scale is smaller, timing and disruption matter.
Ski Resorts Eye a Strong Start
Mountain resorts like Arapahoe Basin, Keystone Resort and Loveland Ski Area are anticipating total snowfall of 18–24 inches over the next 10 days in higher terrain.
That kind of early accumulation helps build a base for the season—good news for businesses, winter sports enthusiasts and local economies. The timing couldn’t be better to kick off winter activity.
Freezing Temps are Coming Fast
Expect the thermometer to drop statewide with temperatures forecast to plunge below freezing by Tuesday night, marking the season’s first widespread frost.
Freeze warnings are likely for Denver and surrounding regions. For gardeners, homeowners and commuters alike, it’s a sign to cover plants, prep pipes and adjust routines. Winter is arriving in earnest.
Wind Chill and Blowing Snow Make it Feel Colder
In mountain towns, the combination of wind and snow will push “feels-like” temperatures into the teens. Emergency officials are reminding travelers to carry warm gear, extra blankets and chains when venturing through the Rockies this week.
The savings in comfort may be minor—but the risk isn’t. Better safe than stranded.
Minor Shifts Could Change Everything
The NWS and CDOT say they’re monitoring every twist of the storm’s path, because even small shifts can determine whether Denver sees a dramatic snow cover or just a chilly breeze on Halloween.
Officials stress staying up to date with the forecast, and treating the situation as dynamic as what’s true today may change tomorrow.
A Halloween to Watch—Both Spooky and Snowy
As Colorado braces for these twin storms, officials stress this is a time for preparedness and to avoid non-essential mountain travel, secure outdoor décor and keep an emergency kit ready.
Whether this Halloween ends up with a dusting of snow or full-blown flakes, the message is clear that winter’s foot is already on the door in Colorado’s high country. Stay alert, stay ready and maybe pack a heavier jacket.
