July 2020 Summary

July was a typically stormy month with severe weather reported on nine different days, including all but one day from the 5th to the 12th. The great majority of the damage was to trees, with some isolated minor structural damage. On the 8th a downburst hit the east side of Louisville, bringing down a few trees and large branches in the Goose Creek area. A few days later on the 11th a large bow echo swept south from northeast Illinois through central and southern Indiana into central Kentucky, blowing down trees as it went. Tree damage was widespread in Harrison County, Indiana, winds at Clark County Regional Airport near Sellersburg were measured at 59 mph, and a billboard was blown into the middle of the street near the intersection of Lexington Road and Grinstead Drive in Louisville.

On the 30th-31st torrential rains fell near an east-west front stretched along the length of Kentucky. 48-hour rainfall totals were mostly in the 2-4 inch range, with a few spots topping five inches along and just north of the Ohio River. Thanks to preceding dry conditions and plenty of vegetation, there was little if any flooding outside urban Louisville.
