Forecast table times: UTC.
Coordinates: 39.2126962°N, -106.9206131°E · Requested elevation: 2474 m. Model terrain: 2870 m. Terrain and 1000/925/850/700 hPa profiles are used for height estimates.
Outside the available profile, temperature uses an estimated 5.5°C/km height correction; wind retains the nearest available model-level value. Humidity is estimated with adjusted pressure and temperature.
These are altitude estimates, not a simulation of local mountain terrain. Precipitation, cloud and sea-level pressure use horizontal interpolation only.
Precipitation includes rain and snow water equivalent: preceding 3 hours through day 6, then 6 hours (see cell tooltip). Snow (cm) estimates fresh snowfall from precipitation and temperature using the GFS conversion; it is not snow depth on the ground. Freezing (m) uses additional 600/500 hPa temperatures when available and estimates the lowest resolved 0°C crossing above sea level. When all sampled levels are warm, the upper profile limit is shown (see tooltip). < marks an entirely cold sampled profile and its lower height limit. No extrapolation is used.

This listing refers to Snowmass mountain, one of the four mountains marketed together as Aspen Snowmass. Snowmass has a broad mix of terrain, from prepared runs and family areas to steeper skiing such as the Cirque. Its base village and Elk Camp facilities also give groups options beyond a day spent entirely on skis.
The distinction between Snowmass and the wider Aspen Snowmass destination is important when choosing a meeting point or reading a mountain report. A webcam, lift update or snowfall measurement from Aspen Mountain is not automatically a report for Snowmass. Start with the named mountain and then identify the sector you plan to use.
Our lower forecast reference is at 2,474 m. For higher terrain, select a matching altitude rather than applying the base temperature everywhere. For a family day, check the hourly outlook for both the start and the return: the warmest or coldest part of the day may not coincide with the precipitation. Use the resort’s trail and grooming report to understand available terrain, alongside the two-model weather comparison.
