The criteria for Heat Advisories and Excessive Heat Warnings are changing in the eastern Oklahoma and Texas Panhandles.

Beaver, Lipscomb, Hemphill, Wheeler, Collingsworth, and Donley Counties previously needed either a temperature or heat index value of 110 to 114 for a Heat Advisory and 115 or greater for an Excessive Heat Warning.

This means that, starting May 1st, 2024, the criteria for the entirety of the Oklahoma and Texas Panhandles, including Palo Duro Canyon, will be the same: 105 to 109 for a Heat Advisory and 110 or greater for an Excessive Heat Warning.
