September 2007 was ushered in with generally above average temperatures and below average rainfall in the Brazos Valley. The wettest part of the month was the three day period from the 3rd through the 5th as a total of 0.72" of rain fell. Most of the precipitation fell during the first ten days of the month. High pressure then built into the region providing dry conditions. From the 11th through the end of the month only two precipitation days were recorded. Average daily temperatures were generally above average owing to warm nighttime temperatures. Records for highest minimum temperature were tied on the 6th, 7th, and 9th. Near records were set on the 5th, 8th, and 30th. Minimum temperatures gradually cooled as the month progressed but were still generally above average.

For the month, 1.45" of rain was recorded which is 2.46" below average. The average monthly temperature was 81.6°F, which is 1.9°F above normal.
