NWS Forecast Accuracy
Good news — NWS underestimates snowfall here by 100%
Snowmass typically receives 2.7× the NWS forecast amount. When NWS says 6 inches, you should expect closer to 16 inches. StormDrop calibrated estimates account for this.
Sample size is only 2 storms, both from same date (2026-03-15) with nearly identical conditions. Pattern is consistent but confidence is limited. High wind (23–25 mph) and low SWE may indicate wind-loaded snow or sublimation/settling already occurring at forecast issuance. Recommend collecting more spring season data before deploying adjustments operationally.

Local Knowledge
TGR Community IntelStorm Day Strategy
Snowmass receives localized spring storms with significant accumulation variation between peaks. Monitor snow reports carefully as Snowmass often under-reports totals compared to Highlands and Ajax. Spring storms can dump 10-16+ inches while official reports show 1-2 inches. Easterly aspects offer best snow quality during frontal passages. Storm timing creates opportunity to ski empty terrain while neighbors report minimal snow.

Temperature effect: Both storms occur at identical avg temp (12.6°F). At this marginal spring temperature, actual snow exceeds forecast 2–3×; may indicate NWS underestimates wet/heavy snow conversion or assumes loss to rain.
