Flash Flood — Apr 30, 2025
A weak cold front slowly advanced southeast into portions of Northeast Texas, Southeast Oklahoma, into Western Arkansas and Southern Missouri on April 30th, and focused a warm, very moist, and unstable air mass in place across much of East Texas, North Louisiana, and Southwest Arkansas during the afternoon through the evening hours. Meanwhile, an upper low pressure area ejected northeast from t...

A weak surface frontal boundary drifted south to near the I-20 corridor of East Texas and North Louisiana during the early morning hours of May 26th, with a warm and moist air mass along and south of the front yielding adequate instability along and south of the front. While scattered strong to severe thunderstorms over portions of extreme Northeast Texas, Southeast Oklahoma, and Southwest Arka...

Strong heating ahead of the front and attendant trough contributed to increased instability, with large scale forcing from these surface and upper level features contributing to scattered strong to severe thunderstorms containing heavy rain...

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...

Grounds were already saturated from widespread rains of an inch and a half to in excess of three inches that fell i...
