14-day mountain weather & snow
GFS · ECMWF IFS · AIGFS · AIFS · GEM. Forecast at an indicative destination point; not a summit forecast or live snow depth.
Equal-weight blend of available complete local days. Days 8–14 are less certain; missing data remain blank. Snowfall cm are fresh snow, not snow depth. Sea-level pressure. Terrain temperature downscaling by Open-Meteo; no Agios Stefanos calibration. A point forecast cannot describe every piste or assess avalanche danger. Open-Meteo

This summary uses the destination’s fixed coordinates and the historical service’s terrain elevation. It does not change with the forecast’s manual elevation setting. Mountain terrain, wind redistribution and snowmaking are not fully represented. Snowfall days do not indicate opening days or piste snow depth.
Explore rain and snowfall frequency, monthly average daily lows and highs, and daily temperature extremes within this decade.

These are ERA5 reanalysis estimates on an approximately 25 km grid, with provider temperature downscaling, rather than station observations or official records. This decade is not a 30-year climate normal.
Rain day: liquid rain ≥1 mm. Snowfall day: modeled new snowfall ≥0.1 cm, which does not imply snow cover. Precipitation includes rain and the water equivalent of snow. Snow frequencies are especially approximate in mountainous and coastal locations.
Monthly averages use complete months and annual averages use complete years for each variable. Temperature extremes use complete available years within this decade. Coverage is shown on the cards and in table cell tooltips. This historical summary does not apply a forecast calibration.

A downhill ski area in Utah, United States, with mapped lift-served terrain.
Before you go
Check the operator’s current piste map, lift status and access information before setting off.
Plan your visit
Consider temperature, fresh snow and wind together. Conditions at the base may differ from the upper slopes. Set an elevation in the forecast to explore a different level of the mountain.
Nearby settlements and area
A nearby listed settlement is Lindon, approximately 12 km from the forecast point in a straight line. GeoNames lists a population of 10,810 for this settlement.
Population refers to the settlement, not the ski area or its visitors, and may not reflect the latest census. Source: GeoNames · CC BY 4.0
The forecast point is at 40.3798, -111.5879, using the America/Denver time zone. The nearby ski-area links below let you compare conditions across the region.

Weather models and where they come from
AIGFS
USA · NOAA / NCEPArtificial Intelligence Global Forecast System: a machine-learning model initialized from NOAA atmospheric analyses.
ECMWF IFS
Europe · ECMWFIntegrated Forecasting System: the intergovernmental European centre’s numerical model. IFS 9 km and IFS 0.25° are products of the same model family on different data grids.
ECMWF AIFS
Europe · ECMWFArtificial Intelligence Forecasting System: this page uses AIFS Single, which produces one forecast scenario.
GEM
Canada · ECCCGlobal Environmental Multiscale: the atmospheric model within Canada’s GDPS. The current system combines numerical prediction with large-scale guidance from the GEML AI model.
The blend uses the values available for each day and variable. Coverage falls as individual models reach their forecast limits. The two IFS products are not independent models. Model spread shows disagreement, not the probability of a weather event.
Wind: maximum daily speed at 10 m and prevailing direction of origin. Direction uses a speed-weighted circular calculation; missing or strongly opposing directions display a dash. 🥶: low below 0°C. 🥵: high above 30°C. 💨 in Conditions: wind at least 40 km/h or gusts at least 60 km/h.
