A combination of clear skies, light winds and drier air allowed temperatures to dip into the 30s for lows across much of west-central Texas, on the early morning of the 1st. Several locations recorded lows in the lower to mid 30s.
Gusty south winds developed on the 2nd and continued on the 3rd, well out ahead of a developing upper level storm system over the southwestern U.S. Abilene Regional Airport recorded peak wind gusts of 46 mph on the 1st and 42 mph on the 2nd. The south winds brought an increase in moisture to the area from the Gulf of Mexico.
A widespread and beneficial rain event occurred on the 4th and 5th. Several factors came together to bring about this notable event for November. A strong upper level storm system slowly approached from the southwestern states, with southwest flow developing aloft over Texas and Mexico. With this setup, moisture aloft was pulled into Texas from a tropical system in the Eastern Pacific. Low-level moisture from the Gulf of Mexico was incorporated into the region during the previous 1-2 days. A cold front moved slowly south across west-central Texas on the 4th, helping to focus an area of showers and thunderstorms across the area. with showers and thunderstorms occurring a cold front moving slowly southeast into the area, and a rather moist airmass. New daily rainfall records were set on the 4th at San Angelo (2.48 inches) and Abilene (1.99 inches). A large area of light to moderate rain continued on the 5th. Figure 2 (below) shows total rainfall amounts for this event.

Total rainfall for west-central Texas was generally between 1.5 and 3.5 inches. A few locations across the southern half of the area received more than 3.5 inches. This rainfall was beneficial in the short term across the area.
Temperatures were much cooler behind the front, accompanied by somewhat gusty north to northeast winds on the 4th. Rather cool temperatures (in the lower to mid 50s across most of the area) continued on the 5th as the rain continued, with cloudy skies.
