Cooler than Normal Spring and Summer of 2007
(Updated 8 August 2007)

 

  It has been cooler and wetter than normal across much of Texas this summer. While the rainfall has tapered off across the South Plains during July, temperatures have remained seasonably cool. High temperatures at the Lubbock Airport were on average 5.4 degrees lower than normal in May, 3.3 lower in June, and 2.6 lower in July. The yearly high temperature so far was 98 degrees on June 18th. The forecast weather pattern for middle August indicates a warming trend, with high temperatures now above average, which is lower 90s. However, with the passing of our climatological peak in high temperature for the year, our chances for reaching or exceeded 100 degrees this year is on the downswing. The last time Lubbock failed to record a 100 degree temperature in a year was 1991, or over 15 years ago. Only four years in the record have we failed to reach the century mark. The following graph shows the historical record at Lubbock of temperatures reaching or exceeding 100 degrees. Please click on the graphic for a larger version
