The thirty-day outlook for November 2016 had called for above normal temperatures and below normal precipitation. When revised on October 31, it called for above normal temperatures and near normal precipitation. Upper air high pressure, centered over the Southeastern United States, continued from late-October to control the area's weather through the 3rd. This brought warm temperatures.
Beginning the 4th, upper air low pressure, situated to the west and north of the region, permitted disturbances and weak cold fronts to cross. This brought light showers and slightly lower daytime temperatures to East Texas though heavier rains fell along the Gulf Coast and over North Central and Northwest Texas. Upper air high pressure, centered to the west of the region, returned on the 8th. This permitted cold fronts to cross at about 48-hour intervals. Temperatures lowered back to near normal levels through the morning of the 14th, There was no rainfall.
Upper air high pressure returned on the 14th, warming temperatures to well above normal levels through the morning of the 18th. This was ahead of an upper air trough, which crossed with its attendant cold front on the 18th. Showers accompanied this front, followed by cooler temperatures through the 21st. Warming occurred on the 21st and 22nd.
On the evening of the 22nd, a strong upper air disturbance combined with ample moisture and another cold front brought widespread showers and thunderstorms to the area, with between one and five inches of rain. Cooling back closer to normal began on the 23rd, reinforced by another cold front on the 25th. Temperatures warmed on the 27th and 28th ahead of a storm system which crossed on the latter date. That brought widespread rain and thunderstorms to the region with amounts of up to one inch. Winds of up to 50 mph accompanied some of the thunderstorms. Temperatures cooled on the 29th and 30th behind the cold front, with a reinforcement of the cooler air on the 29th.
