A cluster of showers and thunderstorms developed during the late evening hours of April 29th over Deep East Texas, near and just south of a weak cold front that drifted south across East Texas and North-Central Louisiana. These storms developed in a very moist air mass, near an inverted low level trough that extended from Deep East Texas into West-Central Louisiana. Additional forcing aloft was provided by increasing large scale forcing ahead of a closed upper low over Northern Mexico, which resulted in additional redevelopment of these storms containing heavy rainfall, moving repeatedly over the same areas through much of the early morning hours on the 30th. Widespread rainfall amounts of 3-6+ inches fell across Southern Cherokee, Nacogdoches, Angelina, and San Augustine Counties, which resulted in widespread flash flooding across the areas, with numerous roads closed. These storms diminished by the mid and late morning hours on the 30th.
