Forecast notes
Forecast table times: UTC.
Coordinates: 40.044305°N, -105.9067318°E · Requested elevation: 2539 m. Model terrain: 2838 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.
Granby Ranch is a downhill ski area in Colorado, United States. Mapped terrain includes easy, intermediate, advanced routes. Its mapped lift network extends from approximately 2539 to 2795 metres above sea level. Cross-country skiing is also mapped within the area.
