Several low pressure systems lifted through the Appalachians between the 20th and 24th. The strongest impacted the area on the 21st with moderate to heavy rain totaling 1.25 to 1.5 inches over 24 hours. This fell on already saturated ground, and quickly became runoff into local creeks and streams, pushing some into flooding. Additional rainfall on the 22nd, caused some waterways to surge out of their banks again. Eventually, this water worked its way into the Ohio River, with minor flooding in typical low spots along the river.
