# Snowy Range Ski Area snow forecast, 14-day multi-model blend

Canonical page: https://www.peakcam.io/resorts/snowy-range/snow-forecast  ·  Resort: https://www.peakcam.io/resorts/snowy-range  ·  JSON: https://www.peakcam.io/api/v1/resorts/snowy-range/forecast  ·  Accuracy JSON: https://www.peakcam.io/api/v1/resorts/snowy-range/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)

Truth: 24 h depth change at Brooklyn Lake; 68 measured days; graded at the summit point.

| Rank | Model | Day-1 MAE cm | Day-3 MAE cm | Day-7 MAE cm | Bias ratio | Samples |
| --- | --- | --- | --- | --- | --- | --- |

For every day in the window with a measured value, the forecast for that day from each model's newest run issued 1, 3 and 7 days earlier is compared with the measured 24 h new snow (SNOTEL depth change clipped at zero, so settlement makes the measured value a floor). MAE is in cm; bias ratio is total forecast over total measured; the blend is graded by the same rule.
