Sufficient upslope due to a shortwave trough crossing behind an exiting cold front helped scattered snow showers linger in the ridges. Cold temperatures in the lower levels were credited in keeping snow ratios higher.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS PBZ wrote it up.
Sufficient upslope due to a shortwave trough crossing behind an exiting cold front helped scattered snow showers linger in the ridges. Cold temperatures in the lower levels were credited in keeping snow ratios higher. Low level lapse rates and good moisture in the dendritic growth zone was present at the time as well.
