Overview

Two rounds of thunderstorms impacted extreme southeastern Kansas and the Missouri Ozarks from Wednesday afternoon into Wednesday night. The first rounds of storms produced several reports of large hail during the early and middle portions of Wednesday afternoon. Hail up to the size of golf balls occurred with these storms.

A second round of storms then erupted along a frontal boundary late Wednesday afternoon and Wednesday evening. Several of these storms also produced large hail across southern Missouri. The largest hail stones fell northeast of Mountain View in Shannon County where one hail stone was two inches in diameter. A few reports of minor wind damage were also received from far southern Missouri. Storm surveys have concluded that no tornadoes occurred across southern Missouri.

In addition to the severe weather, multiple rounds of heavy rainfall resulted in flooding creeks and streams across much of southern Missouri. Numerous low water crossings were flooded and closed due to excessive runoff from the rainfall. Many locations saw rainfall amounts between 1 and 3 inches south of the Interstate 44 corridor, with the highest amounts occurring near the Arkansas border.
