Now that May has mercifully drawn to a close, and the south-central states are drying out and cleaning up, we can take full measure of what an incredibly, destructively soggy month it was, especially for Texas and Oklahoma. Both states obliterated their rainfall records for any calendar month going back to 1895. While the rains quickly doused a multiyear drought (see Figure 3 below), the flooding killed at least 31 people, with 6 others missing as of Monday night, a...

The Rains of May and the Science of Recurrence Intervals

By: Bob Henson, 3:54 PM GMT on May 30, 2015

As this memorable month sloshes toward its final weekend, rainfall records have continued to accumulate across the Southern Plains. May is already the wettest month on record in the statewide averages for both Oklahoma (14.43” as of 9:30 am CDT May 30, crushing the 10.75” from October 1941) and Texas (7.54” as of May 27, beating out the ominous 6.66” from June 2004).
