# Great Divide Ski Area snow forecast, 14-day multi-model blend

Canonical page: https://www.peakcam.io/resorts/great-divide/snow-forecast  ·  Resort: https://www.peakcam.io/resorts/great-divide  ·  JSON: https://www.peakcam.io/api/v1/resorts/great-divide/forecast  ·  Accuracy JSON: https://www.peakcam.io/api/v1/resorts/great-divide/forecast-accuracy

Per day, the median snowfall across the models that reach that day (ECMWF IFS, GFS, GEM, ICON, JMA, Météo-France, UKMO, plus NBM and HRRR for US points), fetched every 6 hours from Open-Meteo at the resort's summit and base elevations; the low/high band is the 25th/75th percentile across models, so a wide band means the models disagree.

Per-model values are snowfall in cm per day as the provider stores them; a dash means the model does not reach that day.

## How the models have verified here (90 days)

No scores computed yet; the scorer runs daily once a model run has been graded against a measured day.
