- For
- Colorado skiers comparing resort snowfall forecasts
- Worth noticing
- The map marks forecast areas outside its coverage with a dashed gray boundary, explicitly meaning “no data,” not “no snow.”
Field notes
The resort map distinguishes raw summit snowfall from changes in the adjusted summit estimate between runs; that change marker appears at 0.5 inches or more. A scorecard also compares forecast and observed snow by station and storm, while the explanation notes that HRRR updates hourly and GFS and ECMWF use three-hour steps. The page says 500mb maps are coming later.
