The episode as NWS PAH wrote it up.
Warmer weather just after the middle of the month caused snow in the upper part of the Ohio River basin to melt. This combined with heavy rains around the 20th and 21st to send the Ohio River above flood stage. Some sites crested by the end of the month, however, some would not peak until the first part of February.
