Forecast table times: UTC.
Coordinates: 39.1864051°N, -106.8182053°E · Requested elevation: 2425 m. Model terrain: 2985 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.

Aspen Mountain, also called Ajax, rises directly above downtown Aspen. The Silver Queen Gondola is its familiar access point. It is one of the four Aspen Snowmass mountains, but its terrain should not be confused with Snowmass or Buttermilk: the operator describes Aspen Mountain as primarily suited to intermediate and experienced skiers, with limited beginner terrain.
That distinction matters more than the shared destination name when choosing a first day. A mixed-ability group should consult the current trail map and lesson options before choosing where to meet. A ticket covering several mountains does not make their learning areas or access arrangements identical.
The default forecast is for a lower point at 2,425 m. Choose a higher station for the upper mountain, then compare the hours you intend to ski. SnowReportMeteo’s centimetres describe forecast fresh snow, while the resort’s snow and grooming report describes conditions on the mountain. Read both: a day without new snowfall can still offer open skiing, and a fresh snowfall does not by itself describe the prepared surface.
