Overnight (June 7th, 2009) a rare atmospheric phenomenon occurred in south-central Oklahoma. No it wasn’t a tornado, it was much more rare than that – even during 2009! Suddenly at about 3am CDT in Jefferson County the air temperature became very hot and dry, the temperature shot up to 97 degrees F, literally within minutes. The event that happened is called a Convective Heat Burst, it happens when a parcel of very cold and unsaturated air within a dying storm descends very rapidly and warms due to compression (at a rate of 9.8C per 1,000 meters) and overshoots its equilibrium level and reaches the surface.
