A weak surface trough developed from the Texas Hill Country into Deep East Texas and Northcentral Louisiana during the daytime hours of December 7th, which was further enhanced as a developing warm front ahead of a strong upper level trough that translated east across much of Texas. This trough tapped into a rich supply of Pacific moisture as it spread northeast across Texas and the Lower Mississippi Valley, with strong overrunning atop this weak surface trough/warm front ahead of the upper level trough as it entered West Texas late in the day. While much of the rains during the 7th were stratoform, rainfall intensity increased during the evening and overnight hours across much of East Texas and North Louisiana, where widespread rainfall amounts of four to in excess of six inches was observed across Deep East Texas, much of North Louisiana, and extreme Southern Arkansas. These totals, atop already moist grounds from significant rains and flash flooding that was observed in Mid-November, resulted in increased runoff and flash flooding across much of Angelina County and adjacent portions of Deep East Texas, with numerous other creeks and streams rising/cresting above flood stage during the morning/afternoon hours on December 8th across East Texas, well after the heavier rains had ended. This resulted in numerous other roads across East Texas becoming flooded and closed through the remainder of the 8th.
