A strong upper level low pressure system tracked east across the Red River Valley of Southern Oklahoma and North Texas during the afternoon of January 8th, before shifting across Northeast Texas into Southwest Arkansas during the early morning hours of the 9th. Ahead of this low, strong southerly low level winds rapidly transported low level moisture back north across the region, with large scale forcing and elevated instability ahead of the low contributing to areas of showers and embedded thunderstorms over East Texas, North Louisiana, and Southwest Arkansas. An isolated severe thunderstorm developed during the afternoon of the 8th over Nacogdoches County in East Texas, producing ping pong ball size hail just southeast of Nacogdoches. Meanwhile, a warm front spread north into portions of Deep East Texas and Central Louisiana during the late evening and early morning hours, with increasing instability and low level wind shear fueling the development of strong to severe thunderstorms over these areas. These storms produced damaging winds which downed trees and limbs in Sabine County, with additional severe storms later spawning two tornadoes in Southern Sabine Parish, Louisiana. These storms also continued to develop and move repeatedly over the same areas during the early morning hours across extreme Southeast Angelina, Southern San Augustine, and Central Sabine Counties, producing a narrow swath of heavy rain with amounts ranging from 3-7+ inches. This resulted in extensive flash flooding across Southern San Augustine and Central Sabine Counties, before the storms shifted east into West Central Louisiana just prior to daybreak on the 9th.
