Flash Flood — May 6, 2025
An upper level low pressure system over the Desert Southwest shifted east through the Intermountain West on May 6th, inducing surface low development over West Texas. This also resulted in a tightening pressure gradient across the Southern Plains and Lower Mississippi Valley, with increased southerly low level winds allowing for a warm front to shift north to the I-20 corridor of East Texas and...
Flash Flood — Apr 28, 2024
Regenerative thunderstorm development occurred during the afternoon on April 28th across Central Texas along existing outflows from an MCS that decayed earlier in the morning. Surface temperatures continued to warm into the upper 70s to lower 80s within cloud breaks south and east of the large-scale outflow boundary across East Texas into North Louisiana. This led to moderate buoyancy with uppe...
Flash Flood — Jun 3, 2024
A linear mesoscale convective system (MCS) advanced southeast into the Ark-La-Tex from Oklahoma during the afternoon and evening hours on June 3rd. 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 ...
Tropical Storm — Aug 27, 2020
Major Hurricane Laura tracked north northwest across the Central and Northern Gulf of Mexico from the Central Carribean Sea near Cuba, making landfall in Southwest Louisiana near Cameron around 1 am on August 27th as a strong Category 4 hurricane with maximum sustained winds near 150 mph, and a minimum central pressure of 938 mb. Laura remained a hurricane as it tracked north across Southwest a...
Flash Flood — Apr 22, 2020
An upper level trough ejected east-northeast across the Oklahoma/Texas Panhandles during the morning of April 22nd, before shifting across much of Oklahoma during the afternoon. Meanwhile, a warm front over Central and Southeast Texas into Southern Louisiana lifted slowly north into portions of East Texas and Central Louisiana during the afternoon. Large scale forcing quickly increased ahead of...
