Colour guide Temperature · Wind · Rain · Snow
Each colour starts at the value shown. Wind colours match across all three units. Dry cells stay neutral. Colours describe the displayed values, not official weather warnings.
Preparing forecast graphs…
Times and values match the detailed forecast. Tap or point at a value for details. Scroll each chart sideways for later days. Rain / precipitation is the total water equivalent per forecast interval, including snow; snowfall is fresh snow per interval, not snow depth.
GFS and ECMWF model comparison. Each model retains its own forecast times and horizon. Precipitation and snowfall amounts cover their own forecast intervals; these can differ between models.

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.
