Flash Flood — Nov 24, 2025
A mature linear thunderstorm complex developed across the Middle Red River Valley on November 24th and extended from Southwest Arkansas south-southwestward into East Texas and Northwest Louisiana. This thunderstorm complex was slow in its forward propagation eastward while producing areas of 0.5-1 inch/hour rain rates. An outflow boundary from this activity also extended farther westward from L...
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 5, 2025
A stationary front extended across portions of Northeast Texas and Southwest Arkansas during the early morning hours on April 4th, but lifted north into Southeast Oklahoma and Western Arkansas during the day. This was in response to an intensifying low level jet that developed ahead of a large upper trough that extended from the Intermountain West into the Plains, which provided the necessary l...
Flash Flood — May 2, 2025
An upper level trough traversed east across the Southern Plains on May 2nd, which reinforced a weak cold front southeast into portions of extreme Northeast Texas and Southwest Arkansas along the I-30 corridor by afternoon. Strong daytime heating contributed to ample air mass destabilization through the day across the warm and moist sector ahead of the front, with scattered severe thunderstorms ...
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. This led to moderate buoyancy with upper 60s to lower 70s su...
