What happened

The episode as NWS CLE wrote it up.

Cold northwest winds blowing across Lake Erie caused lake effect snow showers to develop early on the 19th. This activity persisted into the evening hours of the 19th and then dissipated. Accumulations on the 19th ranged from 6 to 10 inches. Just after midnight on the 20th, an intense band of snow redeveloped over southern Erie and northern Crawford counties. Thunder and lightning were observed with this band and snowfall rates exceeded three inches per hour at times. The band moved slowly west during the predawn hours. Accumulations from midnight to daybreak on the 20th ranged from 8 to 14 inches over much of southern Erie and northern Crawford counties. The snow finally tapered off during the afternoon hours after several more inches of accumulation. Some locations saw nearly two feet of snow during this two day event. Travel was severely hampered by this storm and dozens of accidents were reported.
