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.
On the 15th low pressure occluded over the Great Lakes and secondary cyclogenesis began near the triple point off the Mid Atlantic coast. Secondary low pressure rapidly deepened into the 16th. This strong low pressure developed an equally strong moisture transport which impinged upon the higher terrain with upslope enhancement. A very marginal air mass for mid January meant that snowfall totals were highly dependent on elevation in order for temperatures to be cold enough for all or mostly snow. Warmer temperatures and downsloping meant that valley locations had significantly less snow than higher elevations. Precipitation was heavy at times but generally fell over a 6 to 10 hour period and limited snowfall totals to around a foot at most.
