Wet Stretch Brought Soaking Rains to Kentucky

From July 30th through August 1st, multiple rounds of rain dropped excessive amounts of rainfall to parts of Kentucky.

What You Need To Know

  • The heaviest of rain fell near and north of I-64 on July 30th
  • Central and southern Kentucky were drenched on July 31st
  • The unsetlled pattern ended after the night of August 1st
  • Some parts of the commonwealth picked up over 4 inches of rain

At the surface, a nearly stationary front setup across the commonwealth, providing one of the mechanisms to trigger showers and storms. Aloft, the upper level pattern was set to send a number of upper level disturbances over the front. 

Adding insult to injury was plentiful moisture within the atmosphere. This was the perfect recipe for heavy rain.

On July 30th, the first disturbance moved through from west to east, and set up a band of heavy rain across northern portions of Kentucky. The Louisville Muhammad Ali International Airport received 2.35 inches, while Bowman Field picked up 3.21 inches. 

From around 7 p.m. to 8 p.m., Bowman Field received 1.20 inches of that total, leading to a flash flood warning to be issued.

Farther north, the Cincinnati/Northern Kentucky International Airport received a total of 2.00 inches of rain on July 30th. By far, the heaviest rain fell near and north of Interstate 64 on July 30th. 

That would change the next day.

The stationary boundary would be draped farther south on July 31st, focusing the heavy rain threat across central and southern portions of Kentucky. On this day, the Bowling Green Airport picked up a little over an inch of rain, with other areas nearby seeing an excess of two inches. 

Areas north of I-64 were mostly spared from this round of rain, which helped ease the threat of flash flooding.

An area of low pressure and cold front would push across Kentucky on the 1st of August, bringing another round of showers and thunderstorms, but also marking the end of the unsettled pattern. Rainfall was more scattered on this day, as more consistent and steady rain was pushed north with the front into Indiana. 

Still, portions of northern Kentucky received another inch or more by late in the evening, including the Northern Kentucky Airport.
