On the afternoon of September 22nd, a flash flood watch was issued to cover southeast Indiana and areas in and around the Bluegrass Region of Kentucky.
By September 23rd, a cold front stretched west to east from western Tennessee to far
east-central Kentucky on through eastern Kentucky. The front was tilted northward with the 700 mb level of the front just north of the Ohio River. Low level northward flow carried moisture and overran the front producing widespread stratiform rain showers. The pattern was in response to the area sitting under the right entrance region of an upper level jet.
The quasi-stationary front produced showers with high rainfall rates and slow movement to the east into the Bluegrass and northeastern Kentucky. The ground east of Interstate 65 and in counties along the Ohio River was already saturated from previous rainfall. The high rainfall rates and slow system movement caused widespread flash flooding and areal flooding through southern Indiana and the Bluegrass Region of Kentucky.
On September 25th ahead of an advancing cold front, a saturated air mass was in place with precipitable water values near two inches. With this air mass and shear ahead of the cold front, convective showers formed over southern Indiana and advanced east along Interstate 65 causing flooding issues in the system's path.
