Pretty neat graphs they had from the Mitchell Airport. Temp rose from ~70 to 96 in about 5 minutes. I bet that had some old-timers who thought they knew South Dakota weather really well scratching their heads, if they've never experienced one before.

That's a pretty interesting happening. Thanks for posting the link. Does this part of SD experience this occurrence very often?

I wonder if they renamed the Corn Palace to the Popcorn Palace?:D

Do these only happen out in the plains? I've never heard of them happening in the midwest. Very interesting.

If true...this one in 1960 seems pretty wild

In 1960, the town of Kopperl, Texas (http://en.wikipedia.org/wiki/Kopperl%2C_Texas), experienced a heat burst sending the air temperature to near 140 °F (60 °C), supposedly causing cotton crops to become desiccated and drying out vegetation.[11] (http://en.wikipedia.org/wiki/Heat_burst#cite_note-10)

I hadn't heard about heat bursts until May 25th this year when it happened the night before in OK and affected the moisture return for that day in KS. I wonder how often these go unnoticed.

It takes an observation point for it to even be picked up. Since there are storms ongoing in the area, at least now-a-days, it's probably a good bet that someone will see it in the obs as its happening. Also, during the two heat bursts I've experienced, some pretty strong winds were produced due to the collapsing storm...high enough that High Wind Warnings were issued.

South Dakota has quite a history of heat bursts, I think one of the WFO's used to have a page on it and I do believe Mitchell had quite a heat burst before. Though I think some of the more pronouced one's were during the overnight, 27 degree change would certainly get anyones attention.
