Katherine Hayhoe claims that record rainfall events have increased in West Texas.
In Crosbyton, Texas (the closest USHCN station to Lubbock) only one of the ten rainiest days occurred since 2000. By contrast, two of the top three occurred in 1913.
In Snyder, Texas – four of the top ten occurred since 2000. Perhaps they moved their rain gauge to the bottom of the drain pipe.
