NWS Forecast Accuracy
NWS forecasts at Montana Snowbowl are reasonably accurate based on 5 verified storms.
Analysis cannot be performed. All 5 storms lack actual snowfall verification data (SNOTEL actual snowfall, actual SWE, and density ratio all marked as n/a). SNOTEL depth and SWE beginning values are provided (105.0 inch depth, 37.6 inch SWE) but post-storm measurements are missing. NWS forecasts range from 0.2 to 0.8 inches with consistent dense snow density and minimal wind (2.3 mph) across all events. Snow levels vary from 411 to 903 feet, suggesting elevation-dependent precipitation. Without verified actual measurements, no forecast error analysis, bias quantification, or correction rules can be reliably derived. Recommend obtaining complete SNOTEL post-storm depth and SWE readings to enable meaningful pattern analysis.
