Winter Storm

A complex winter storm evolved in the region late in the evening on the 30th into the morning on the 31st. An initial band of heavy snow moved through the local, producing 1-3" of snow in only a several hour period for many spots near/north of the Ohio River. This snow eventually overspread the remaining parts of the local area through the nighttime hours as precipitation transitioned to more of a mix of snow, sleet, freezing rain, and eventually just to a cold rain by daybreak. The precipitation stayed snow longer near/north of I-70, resulting in slightly higher accumulations. But the rainfall on top of the fresh snowpack created substantial and rapid compaction of the snow in many spots. This may have resulted in reported totals that were slightly less than actually occurred.
