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.

Big Rock Mountain has no measured daily snow series, so the models cannot be verified here; the ranking on resorts with a SNOTEL station is the best guide. How the blend is built and verified.
