The episode as NWS GYX wrote it up.
A strong area of low pressure moved northeast out of the Ohio River valley spreading heavy rain and warm temperatures into the region. Temperatures warmed into the 50s with 3 to 5 inches of rainfall. The combination of heavy rain and melting snow caused streams to overflow their banks and wash out roads.
