COLORADO – Denver, Colorado Springs, Boulder and Fort Collins are approaching winter 2026 27 with a reminder that Colorado's historical annual snowfall averages approximately 71.07 inches across weather stations statewide. While El Niño can influence storm tracks and seasonal temperatures, it does not eliminate major snowstorms, dangerous cold or mountain travel disruptions, including winter weather extending through March.
According to the National Oceanic and Atmospheric Administration NOAA , its October 15, 2026, outlook for December through February places much of Colorado in an equal chances temperature category, with warmer than normal conditions favored in northern areas. Above normal precipitation is favored across portions of southern and eastern Colorado, while other areas have no clear precipitation signal. These outlooks describe seasonal probabilities, not predicted snowfall totals.
What Colorado's Snowfall History Actually Shows Colorado's 71.07 inch historical average reflects weather stations statewide rather than Denver's individual snowfall normal.
Snowfall varies dramatically across the state. Mountain communities near Steamboat Springs, Vail and Aspen routinely experience substantially more snow than lower elevation communities along the eastern Plains.
NOAA historical maps examining El Niño winters from 1950 through 2009 show above average snowfall tendencies across portions of Colorado, particularly during stronger events.
However, those maps do not establish a directly comparable statewide El Niño snowfall average.
Even below average snowfall can produce dangerous conditions.
Why El Niño Doesn't Guarantee an Easy Winter El Niño influences the Pacific jet stream, potentially redirecting moisture bearing storms toward the southwestern United States and southern Rockies.
For Colorado, storm direction and elevation are especially important.
Upslope winds along the Front Range can produce substantial snowfall around Denver, Boulder and Colorado Springs when moist air rises against the Rockies.
Meanwhile, Arctic cold outbreaks can bring freezing temperatures and blowing snow to the eastern Plains.
A winter averaging warmer than normal can still produce major mountain snowstorms and hazardous travel.
What This Means Through March Travelers along Interstate 70 through the Eisenhower Tunnel and Vail Pass, Interstate 25 between Denver and Colorado Springs, and Interstate 76 across northeastern Colorado should remain prepared for changing winter conditions.
Mountain passes face drifting snow, reduced visibility and chain restrictions, while eastern highways can experience ground blizzards.
NOAA's December–February outlook does not include March 2027, when significant Front Range and mountain snowstorms remain possible.
El Niño changes Colorado's seasonal weather probabilities, but it does not guarantee a snow free or disruption free winter.
