The episode as NWS SHV wrote it up.
A southwest to northeast band of persistent moderate to at times heavy rainfall developed during the early evening hours on October 15th across portions of Central Angelina and Southeast Nacogdoches Counties in Deep East Texas, as strong overrunning began atop a cool, shallow air mass in wake of a cold frontal passage that moved through earlier in the day. The rain rates were enhanced by late evening through the early morning hours on October 16th, where strong elevated forcing occurred near embedded upper level disturbances in the deep and very moist southwest flow aloft. This resulted in widespread areas of four to seven inches of rain across Central Angelina and Southeast Nacogdoches Counties, which resulted in multiple roads being covered in water and/or closed across Southern and Central Angelina County during the early morning hours on October 16th.

For the 16/06Z TAFs, IFR/MVFR cigs to prevail, possibly with some intermittent LIFR cigs at times, with widespread rain continuing at all terminals during this period. Little if any change in these conditions is expected, but vsbys may fluctuate due to rainfall intensity. Otherwise, look for brisk northerly winds around 10 kts with occasional higher gusts between 15-20 kts. Winds quickly shift S/SW around 5Kft above the surface with speeds gradually increasing to near 50 kts at 30Kft. /19/ && .PREV DISCUSSION... /issued 1009 PM CDT Mon Oct 15 2018/ UPDATE... Strong overrunning conditions from SW flow aloft will keep rain going well on through tonight over the region. Intensity has begun slack off in some areas, but moderate to heavy pockets of rain are still noted over much of deep east Texas and into northwest and north central Louisiana. For this update, POPs were increased nearly across the board with no signs of rain ending anytime soon. Temperatures continue to dip a few more degrees in the wake of the cold front, but they should begin to hold steady after midnight with overcast conditions and persistent rain. Thus, no additional changes are needed at this time. Updated text products have been issued. /19/ && .PRELIMINARY POINT TEMPS/POPS...

A strong cold front will continue to shift southeast across Deep East Texas and North Louisiana this afternoon. Widespread light and moderate rain well behind this front will slowly spread across the region later today and tonight. Brief periods of heavy rainfall will be possible, with rainfall amounts of one to three inches expected through late tonight. This may result in minor flooding of low lying, poor drainage areas, as grounds are nearly saturated in the wake of above normal rainfall that has fallen since early September. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday... Showers will remain widespread over much of the region Tuesday, before gradually diminishing Tuesday night. Showers will begin to increase once again from the west Thursday night and Friday as a series of upper level disturbances move back over the area. These showers will begin to diminish from north to south Saturday as another cold front quickly shifts south over the area, reinforcing cooler and drier air back south for the latter half of the weekend. .SPOTTER INFORMATION STATEMENT... Activation of emergency managers, spotter networks, and amateur radio operators, will not be needed today or tonight. 12
