Flash Flood — Jul 26, 2024
A broad complex of showers and thunderstorms with associated heavy rainfall developed across areas of Deep East Texas and West Central Louisiana by mid to late morning on July 26th. This occurred within an elongated axis of upper-level energy observed along much of the middle and upper Texas coast and up across interior areas of East Texas around the eastern flank of a broader mid-level trough ...

A frontal boundary became stationary across the heart of the Ark-La-Tex region in vicinity of the Interstate 30 corridor on April 8th before slowly advancing southeast on April 9th. Concurrently, very moist southwest flow aloft resulting from a nearly cut-off low across the Desert Southwest provided for precipitable water values near 2 inches. Thunderstorms developed and gradually spread nor...

A pocket of strong instability was present ahead of the line, where MLCAPE values ranged from around 2500 to 3500 J/kg range and surface dew points were in the 70s. Instability along with strong large-scale ascent associated with a vorticity maxima ...
