Lynn County Flood History

Flash Flood — May 31, 2024

Another day of severe thunderstorms affected the South Plains of West Texas on the evening of the 31st. Broad southeasterly low level atmospheric flow allowed thunderstorms to initially develop in eastern New Mexico. Upscale growth allowed thunderstorms to move into West Texas despite a capped atmosphere over the South Plains. This line of thunderstorms produced widespread severe wind gusts fro...

Flash Flood — Aug 30, 2024

Isolated thunderstorms developed across the southern South Plains on the afternoon of the 30th. A very moist atmosphere was able to generate efficient rain producing thunderstorms. A slow moving isolated thunderstorm moving across southern Lynn County produced a wet microburst. Areas along US Highway 87 between O'Donnell and Tahoka were reported to have approximately six inches of water flowing...

Flash Flood — Jun 1, 2023

Rich moisture, a weak upper level disturbance, and several low-level boundaries worked in concert to bring torrential rainfall to portions of the south-central and southeastern South Plains on the first. One of the primary factors, in addition to the plentiful moisture, was a low-level boundary, originating from thunderstorm activity that affected the Texas Panhandle the previous evening into t...

Flash Flood — Aug 28, 2022

On the afternoon of the 28th, scattered thunderstorms developed over the central and southwestern South Plains within a low level convergence zone from a surface pressure trough. Hot temperatures and well above average moisture levels fueled the development of convection as it slowly moved to the east. These slow moving storms brought severe wind gusts and widespread flooding to parts of Lubboc...

Flash Flood — May 5, 2019

Very strong instability developed across the South Plains this afternoon east of a sharp dryline. Scattered thunderstorms developed along the length of this dryline by 1600 CST and slowly matured into severe thunderstorms, including supercells. A remnant outflow boundary near the US Highway 84 corridor drifted west and interacted with an already stout supercell in southwest Lubbock County. This...
