Flash Flood — Apr 6, 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 — Mar 15, 2024
Strong and deep convection became widespread over the Ark-La-Tex and downstream portions of southern Arkansas on March 15th. This occurred along an outflow boundary on the southwestern flank of a decaying MCS, and a favorable environment encouraged increased training over several hours. The mesoscale environment was characterized by ML CAPE of 1000-2000 J/kg, PWATs of 1.5-1.8 inches, and deep l...
Flood — Feb 8, 2023
A surface low was accompanied by a stalled frontal boundary that extended near and along the Interstate 30 corridor of Southwest Arkansas, Southeast Oklahoma, and far Northeast Texas. Aloft, a closed low was positioned across eastern New Mexico into the Texas Panhandle with a trailing trough well south into northern and central Mexico. This pattern allowed for plentiful Pacific moisture to comb...
Flash Flood — Oct 4, 2023
A prolonged period of heavy rainfall occurred on October 4th across parts of extreme Southwest Arkansas. Showers and thunderstorms with 1-3 inch per hour rainfall rates trained in the vicinity of a warm front, which was draped across the Ark-La-Tex and in adjacent portions of Southeast Oklahoma and Northeast Louisiana. Deep convergence of moisture along the boundary resulted as the core of the ...
