# Castle Mountain Resort snow forecast, 14-day multi-model blend

Canonical page: https://www.peakcam.io/resorts/castle-mountain/snow-forecast  ·  Resort: https://www.peakcam.io/resorts/castle-mountain  ·  JSON: https://www.peakcam.io/api/v1/resorts/castle-mountain/forecast  ·  Accuracy JSON: https://www.peakcam.io/api/v1/resorts/castle-mountain/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.
