How to read this page

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.

Verification scores appear once the daily scorer has graded a run against a measured day. How the blend is built and verified.
