Paragon Posted July 21, 2017 Share Posted July 21, 2017 Has this been confirmed? The data for KIFP (Bullhead City, Arizona) for the night between July 15-16. There was a huge heat burst there and they hit 136 degrees! Here is the data on wunderground. https://www.wunderground.com/history/airport/KIFP/2017/07/15/DailyHistory.html?req_city=Bullhead City&req_state=AZ&reqdb.zip=86439&reqdb.magic=4&reqdb.wmo=99999 Temperature Mean Temperature 114 °F - Max Temperature 136 °F 106 °F 136 °F (2017) Min Temperature 91 °F 85 °F 72 °F (1993)https://www.wunderground.com/history/airport/KIFP/2017/07/16/DailyHistory.html?req_city=Bullhead City&req_state=AZ&reqdb.zip=86439&reqdb.magic=4&reqdb.wmo=99999 Temperature Mean Temperature 112 °F - Max Temperature 131 °F 106 °F 131 °F (2017) Min Temperature 93 °F 85 °F 74 °F (1993) From the data it looks like the heat burst started at 7:55 PM and from there until 1:15 AM it was over 130 degrees! What a massive and long lasting heat burst! By looking at past heat bursts that have occurred in different regions, they always seem to occur late at night- any idea why that might be? Historic heat bursts of the past https://en.wikipedia.org/wiki/Heat_burst#Extreme_cases 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] https://en.wikipedia.org/wiki/Kopperl,_Texas 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] https://en.wikipedia.org/wiki/Cherokee,_Oklahoma#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] Link to comment Share on other sites More sharing options...
dendrite Posted July 24, 2017 Share Posted July 24, 2017 Looks like a malfunctioning sensor to me based on the METARs. Link to comment Share on other sites More sharing options...
MN Transplant Posted July 24, 2017 Share Posted July 24, 2017 Heat bursts are on the order of 10s of minutes. I think dendrite is right that this looks more like an equipment malfunction. Link to comment Share on other sites More sharing options...
Paragon Posted July 28, 2017 Author Share Posted July 28, 2017 It seemed really weird that this occurred for several hours and had multiple peaks, never heard of a heat burst like that before. Sadly, I have to concur with you guys! Link to comment Share on other sites More sharing options...
