the new world record temp at KIFP (Bullhead City, AZ)? It was probably a heat burst but still, it is the first such measurement in the modern digital era! ... .wmo=99999

Mean Temperature 114 °F -
Max Temperature 136 °F 106 °F 136 °F (2017)
Min Temperature 91 °F 85 °F 72 °F (1993) ... .wmo=99999

Mean Temperature 112 °F -
Max Temperature 131 °F 106 °F 131 °F (2017)
Min Temperature 93 °F 85 °F 74 °F (1993)

the heat burst (125+ temps) lasted from 7:55 PM to 1:15 AM !

Extreme cases[edit]
These are cases when temperatures over 56.7 °C or 134 °F (the highest officially confirmed in the world, in Death Valley, United States, 1913) were recorded during heat bursts.

Cherokee, Oklahoma, 11 July 1909: at 3:00 in the morning, a heat burst south of Cherokee, Oklahoma reportedly caused the temperature to rise briefly to 57.8 °C (136.0 °F), desiccating crops in the area.[48]
Kopperl, Texas, United States, 1960: A heat burst sent the air temperature to near 140 °F (60 °C), supposedly causing cotton crops to become desiccated and drying out vegetation.[49]
Lisbon, Portugal, 6 July 1949: A heat burst reportedly drove the air temperature from 38 to 70 °C (100.4 to 158.0 °F) within two minutes, in the region of Figueira da Foz and Coimbra, in central Portugal.[50][51]
Abadan, Iran, June 1967: An extreme temperature of 86.7 °C (188.1 °F) was recorded during a heat burst.[51], ... ma#Climate

On 11 July 1909, at 3:00 in the morning, a heat burst south of Cherokee reportedly caused the temperature to rise briefly to 136 °F (57.8 °C), desiccating crops in the area.[17],_Texas#Climate

Shortly after midnight on June 15, 1960, a freak meteorological phenomenon struck the community when a dying thunderstorm collapsed over Kopperl. The storm had rained itself out, and with little to no precipitation to cool the resulting downdrafts, superheated air was expended upon the community in the form of extremely hot wind gusts of up to 75 MPH. The temperature increased rapidly, peaking near 140° Fahrenheit (60° Celsius); twenty degrees above the official all-time high for the state of Texas. The storm, known as "Satan's Storm" by locals, soon became part of local folklore.[2],_Iran#Climate

The world's highest unconfirmed temperature was a temperature flare up during a heat burst in June 1967, with a temperature of 87 °C (189 °F).[30]

Do you know the causes of this hear burst?

It says in the article they are caused by dying thunderstorms that have rained themselves out so all that is left is a downburst of superheated wind (maybe superheated by lightning?)
