NCBlizzard Posted June 16, 2011 Share Posted June 16, 2011 Here are some documented cases from Wikipedia.org: Some documented cases Memphis, Tennessee, June 13, 2011: Temperatures rose from 75 °F (24 °C) to 149 °F (65 °C) between 1:53 PM and 2:53 PM.[4] Wichita, Kansas, June 9, 2011: Temperatures rose from 85 °F (29 °C) to 102 °F (39 °C) between 12:22 AM and 12:42 AM. The heat burst caused some wind damage (40-50 mph) and local residents reported the phenomenon to area weather stations.[5] Sioux Falls, South Dakota, August 3, 2008: Temperatures rose rapidly from the lower 70 °F (21 °C) to 101 °F (38 °C) in a matter of minutes. Wind speeds also rose with gusts up to 50–60 mph (80–97 km/h).[6] Cozad, Nebraska, June 26, 2008: Wind gusts reached 75 miles per hour (121 km/h), as the temperature rose 20 °F (11 °C)[7] in a matter of minutes.[8] Midland, Texas, June 16, 2008: At 11:25 pm a wind gust of 62 mph (100 km/h) occurred, and the temperature rose from 71 °F (21.7 °C) to 97 °F (36.1 °C) in minutes.[9] (These measurements were taken from miles away, and theories point to 80–100 mph (130–160 km/h) winds in a 2–3 block perimeter.)[10] Emporia, Kansas, 25 May 2008: Reported temperature jumped from 71 °F (21.7 °C) to 91 °F (32.8 °C) between 4:44 am and 5:11 am (CDT)[11] as the result of wind activity from a slow moving thunderstorm some 40 miles (64 km) to the southwest. Canby, Minnesota, 16 July 2006: A heat burst formed in Western Minnesota, pushing Canby's temperature to 100 °F (37.8 °C), and causing a wind gust of 63 mph (55 kn; 101 km/h). The dew point fell from 70 °F (21.1 °C) to 32 °F (0 °C) over the course of one hour.[12] Hastings, Nebraska, 20 June 2006: During the early morning the surface temperature abruptly increased from approximately75 °F (23.9 °C) to94 °F (34.4 °C).[13][14] Sheppard Air Force Base Wichita Falls, Texas, 12 June 2004: During late evening the surface temperature abruptly increased from approximately 83 °F (28.3 °C) to 94 °F (34.4 °C) and causing a wind gust of 72 mph (63 kn; 116 km/h). The dew point fell from 70 °F (21.1 °C) to39 °F (3.9 °C)[15][16] Minnesota and South Dakota, March 26, 1998: A temperature increase of 10–20 °F (6-11 °C) was reported in the towns of Marshall, Minnesota, Sioux Falls, South Dakota, Brookings, South Dakota, and Montrose, South Dakota during a two-hour period.[17] Oklahoma, May 22–May 23, 1996: The temperature in the towns of Chickasha rose from 87.6 °F (30.9 °C) to 101.9 °F (38.8 °C) in just 25 minutes, while the temperature at Ninnekah rose from 87.9 °F (31.1 °C) to 101.4 °F (39 °C) in 40 minutes. In addition, wind damage was reported as winds gusted to 95 mph (153 km/h) in Lawton,67 mph (108 km/h) in Ninnekah, and 63 mph (101 km/h) in Chickasha.[18] Kopperl, Texas, 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.[19] Portugal, July 6, 1949: A heat burst reportedly drove the air temperature from 38 °C (100.4 °F) to 70 °C (158.0 °F) two minutes later (note that the highest temperature formally recognized on the Earth is57.8 °C (136.0 °F) in Libya in 1922, and the former record has not been verified).[20] 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 136 °F (57.8 °C), desiccating crops in the area.[21] Link to comment Share on other sites More sharing options...

It should have caused damage and made huge headlines. I mean, I know it wasn't 149, but did it spike at all? Link to comment Share on other sites More sharing options...

I mean, I know it wasn't 149, but did it spike at all? I thought world record high temp was 136 F. I doubt the 149 is accurate.

I just didn't articulate it the way I meant it in my post. Link to comment Share on other sites More sharing options...
Memphis Weather Posted June 16, 2011 Share Posted June 16, 2011 LOL! Memphis did *NOT* reach 149 Degrees Monday. Typical Wikipedia. The ASOS malfunctioned after recording a 65kt gust during a severe thunderstorm. There was no damage to the unit itself...but several sensors were knocked out of calibration or stopped working all together. Link to comment Share on other sites More sharing options...

I am curious though, have their been any daytime instances of heat bursts documented? I wonder if the mixed layer during the daytime would mix out the strong compressional heating that normally takes place. Link to comment Share on other sites More sharing options...

I wonder if the mixed layer during the daytime would mix out the strong compressional heating that normally takes place. That's a very good question. I'm not aware of any personally though I don't have a lot of knowledge on heat bursts. The ones I have seen have all indeed been nighttime events...generally in the plains as thunderstorms there die out. A good theory there perhaps that a mixed layer during the afternoons may prevent these from reaching the surface. Link to comment Share on other sites More sharing options...
