Excessive Heat in Jim Hogg, Texas

The Automated Weather Observing System at the Jim Hogg Co. Airport recorded heat index values ranging from 111 to 116.98F, as the final day of a three-day mini June heat wave continued to produce dangerous, extreme feels like temperatures across the area. The period of extreme values (116F) lasted for around two hours. Dangerous heat (111 to 115) stretched from 1255 until 6 PM. It was unknown dangerous heat may have caused significant casualties, but data would not be available until a later date.

As developing Tropical Storm Arthur moved along the middle Texas coast (June 17) and as a degenerated low pressure system along the Louisiana Coast (June 18), very hot air descended on the southern tip of Texas, with record extreme heat index, or feels-like, temperatures for the entire region on the 18th. The high heat index values held on into June 19th, before unsettled weather brought slightly lower temperatures and pockets of rain by the 20th, which ended the short but brutal window of extreme heat.
