Hot and humid conditions occurred on the 1st.  With moist and unstable air, along with the approach of a dryline from the west, scattered showers and thunderstorms occurred in the Big Country on the (late afternoon and evening) of the 1st.  Highs were in the lower to mid 90s across most of the area. 

A cold front moved southeast across west-central Texas on the 2nd.  Isolated showers and thunderstorms occurred along and ahead of the front. Temperatures climbed into the lower to mid 90s across central and southern sections of the area, just ahead of the front. Cooler and drier air followed passage of the front, and remained over the area on the 3rd and 4th.

Temperatures were well-above normal on October 6-10, when an upper level high pressure system gradually shifted east across central and southern Texas.  The hottest daytime temperatures occurred on the 7th, when a new record high of 98 degrees was set at San Angelo. The high of 98 degrees at Abilene was just one degree below their record high temperature for the date. 

A severe weather event occurred on the evening and early nighttime hours of the 10th, with the approach of an upper level disturbance and arrival of a strong cold front into an unstable airmass.  Most of the severe weather occurred across the northern Concho Valley and northern Heartland areas.  (use svr clr animated radar image to show track of supercell storms) (include link to summary lsr)

Showers and thunderstorms continued into the overnight hours across eastern and southern sections of west-central Texas. The higher coverage of showers and thunderstorms was generally south of Interstate 20 and north of Interstate 10.

Figure 2.  Rainfall for the 24-hour period ending at 7 AM, October 11th.

The heaviest rainfall (between 2.5 and 4 inches) occurred across parts of the northeastern Concho Valley and southern Big Country, and in central and southern parts of Mason County.    

Following the cold frontal passage, temperatures were much cooler on the 11th.  Considerable cloud cover held temperatures into the 60s for highs across most of west-central Texas.  Moisture quickly returned to the area on the morning of the 12th, as southerly winds returned. Patchy fog occurred in southern parts of the area along the Interstate 10 corridor. A quick warmup ensued on the 12th, and south winds increased ahead of an approaching strong upper level weather system.

An upper level storm system deepened over the Southern Plains and Texas during the overnight hours of the 12th and 13th. Strong thunderstorms developed on the evening of the 12th across the Big Country area along and north of Interstate 20. A band of storms moved southeast across central and southern parts of west-central Texas during the overnight hours, ahead of a strong cold front. The cold front exited the area by mid-morning on the 13th, followed by gradually clearing skies and an invasion of cooler air.  Strong, gusty northwest winds occurred on the 13th, especially across the Big Country, Concho Valley and Heartland areas, and across Crockett County. Occasional wind gusts of 40-45 mph were recorded across these areas. 

A high pressure system settled southeast into west-central Texas by the 14th.  With this setup, a combination of clear skies, diminished winds and dry air allowed temperatures to dip into the 30s and 40s for early morning lows on the 14th across most of west-central Texas.  The coldest readings (mid to upper 30s) occurred in low-lying areas of western and southern parts of the region.  Similar low temperatures were recorded on early morning of the 15th, when the high pressure system was still in close proximity to the area. 

In the warmup which quickly ensued, temperatures reached the upper 80s to lower 90s for afternoon highs on the 16th.  A weak but dry cold front moved slowly south across west-central Texas on the 17th.
