A snow shower pattern continued into the 28th of February, thanks to several mechanisms. Low-level convergence along a weak surface trough produced some snow showers near the I-70 corridor and south, with upslope influence providing additional support for snow along the Allegheny Front.
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.
