Texas Weather Records

Historical value at Tulia 6NE became available upon digitization and update of previously paper-bound data. It was examined retroactively, found, to be valid and tied the prior stated record.

The 24-hour rainfall of 42.00 inches was reported from an observer 8.5 miles west of Alvin, Texas between 7 AM July 25th and 7 AM July 26th, 1979 in conjunction with Tropical Storm Claudette. Observer reported that the 10-inch gauge was overflowing at his 1 AM reading, and so the 42 inches may be underreported by at least 3 inches. This 42.00-in rainfall exceeds any observed 24-hr precipitation value for the United States. 43.00 inches of rain in this storm is acknowledged as the United States national record 24-hr precipitation amount, but that value appears to have been estimated in a post-storm survey and is therefore not listed here.

Historical value was examined retroactively and found to be valid and exceeded prior stated record. The previously recognized record of 25\", observed in March 2009 at Follett (GHCN-D identifier USC00413225) is documented (here).

On June 2, 2024, just three years after the Hondo hailstone record was established, a new maximum hailstone diameter was set near Vigo Park, Texas. As the hailstone could not be preserved for physical measurement by the NWS or IBHS, the observer captured photographs using reference objects to establish scale. Following a rigorous 2-D analysis by the SCEC and IBHS, the stone\u2019s maximum diameter was determined to be 7.1 inches.
