Reading a Colorado snow forecast for I-70 travel means asking a different question from the one skiers ask. They want to know how much falls. You want to know when it falls, how fast, and whether it lands during the hours you planned to be on the road.
Right now those answers diverge sharply. Call (720) 694-7791.
Where Things Stand
Colorado has been warm and dry this week, with mountain highs in the 40s and clear nights near 20 — poor for natural snow, excellent for snowmaking.
That changes. Forecasters are pointing at a low-ish chance of snow around Saturday 14 November and a stronger signal around Wednesday the 18th, driven by atmospheric river activity pulling moisture inland. Independent outlooks put 6 to 12 inches across central and northern mountain areas with 1 to 2 feet possible in the San Juans, and NOAA’s hazards outlook flags a moderate risk of heavy snow in southwestern Colorado around the 17th.
Confidence drops the further out you look. Treat the 14th as possible and the 16th to 18th window as likely but imprecise.
What a Forecast Means for the Drive
Three numbers matter, and total snowfall is the least useful of them.
Rate. Twelve inches over three days is manageable. Six inches in four hours is not. Ploughs keep pace with accumulation, not with intensity.
Timing. A storm clearing by 4am gives crews a head start before the morning traffic. One still falling at 8am means you’re driving in it alongside everyone else.
Snow level. Recent forecasts have put snow levels around 8,500 to 9,500 feet. That’s the difference between the Eisenhower Tunnel approach being snow-covered and Idaho Springs being wet.
Temperature matters too. Snow falling near freezing is dense and heavy; colder air produces drier flakes that drift and blow. Both cause problems, differently.
Reading the Colorado Snow Forecast for I-70 Travel
| Forecast says | What to do |
|---|---|
| Light snow, overnight, clearing by dawn | Travel normally, add 30 minutes |
| Moderate snow during the day | Add an hour; avoid 7:30–10am |
| Heavy snow during travel hours | Move your departure earlier or later |
| High wind with snow | Expect blowing snow and poor visibility |
| Active warning during your window | Consider travelling a day either side |
The single most useful decision is usually shifting your departure rather than cancelling it. Most storms have a window.
This Weekend Specifically
Vail and Eldora open Friday 13 November, joining A-Basin, Keystone, Wolf Creek, Loveland, Breckenridge and Copper. That puts the full I-70 ski population on the road for the first time this season — and a Saturday snow chance on top of it.
If you’re travelling Friday or Saturday, leave Denver before 6am. Between 7:30 and 10am is the heaviest westbound window even without weather. Our traffic guide covers the pattern, and Vail’s opening weekend guide covers Friday.
Where to Check
COtrip.org is the only source that matters on the day — live closures by segment, traction and chain restrictions, and camera feeds you can look at yourself. A restriction appears there before anywhere else.
Check it the night before and again before you leave. Our closure guide covers what to do if the road shuts, and the traction law guide covers the equipment requirements that apply from September through May regardless of forecast.
Travelling Through a Storm Window
| Vehicle | With ski gear | Suits |
|---|---|---|
 Cadillac CT6 | 1–2 | Soft luggage only |
 GMC Yukon XL | 4 | Families, the standard booking |
 Cadillac Escalade ESV | 4 | Same capacity, more comfort |
 Executive Sprinter | 8–10 | Groups and ski clubs |
 Ford Transit High Roof | 11–13 | Maximum gear capacity |

Frequently Asked Questions
When is the next snow forecast for Colorado?
A low-ish chance around Saturday 14 November and a stronger signal around the 16th to 18th, though confidence drops further out.
How much snow is expected?
Outlooks suggest 6 to 12 inches across central and northern mountains, with 1 to 2 feet possible in the San Juans.
Does total snowfall predict travel trouble?
Less than rate and timing do. Six inches in four hours causes more problems than twelve over three days.
Where should I check conditions?
COtrip.org — live closures, restrictions and cameras, updated before anywhere else.
Should I cancel if snow is forecast?
Usually just shift your departure. Most storms have a window.
Can you still drive during a storm?
Yes, in compliant vehicles with experienced drivers — though nobody drives a closed road. Call (720) 694-7791.
