The weather pattern was fairly quiet during the first 10 days of December. Following a strong cold frontal passage, temperatures were much colder on the 1st. Daytime temperatures were mostly in the 30s across west-central Texas. Dense fog occurred northwest of a Throckmorton to Sweetwater line, during the post-Midnight hours of the 4th. With mostly clear skies and southwest to west winds, temperatures warmed into the mid to upper 70s across much of the area on the 5th, just ahead of a cold front.
With cool air and considerable low-level moisture over the area, low cloud cover and fog developed during the post-Midnight and early morning hours of the 6th and 7th, and during the overnight hours of the 7th and 8th. An upper level disturbance brought a few light rain showers to the northern half of west-central Texas on the 7th.
With considerable low-level moisture over the area, mostly cloudy skies prevailed December 10-13, with lower daily temperature ranges between the early morning lows and afternoon highs. Nighttime temperatures were well-above normal, and a record high minimum temperature (60 degrees) was set at Abilene on the 13th.
A few rainshowers occurred across northern and central parts of west-central Texas on the 14th, as an upper level storm system moved northeast across the Texas Panhandle. Rainfall amounts were less than two tenths of an inch. Following passage of a dryline, gusty southwest winds brought an intrusion of much drier air into the Big Country and Concho Valley during the afternoon.
Areas of fog, locally dense with visibilities of one quarter of a mile or less, occurred during the post-Midnight and early morning hours of the 18th. Most of the fog occurred across the region south of Interstate 20.
With the approach of an upper level disturbance from the west, scattered showers and thunderstorms occurred across the area southeast of a line from Ozona to San Angelo to Abilene, during the post-Midnight and early morning hours of the 19th.
