"Yesterday, we saw two incredible weather phenomena happen during the afternoon and nighttime hours," said FOX Weather meteorologist Jordan Overton.
The first was a potent, long-lasting supercell, also known as a "mothership" supercell for its alien-like appearance, that battered parts of Kansas with a tornado and destructive hail.
Storm chances for Kansas were marginal, but warm, humid air fueled the storm. The atmosphere was then stirred up as that mass of hot air was pushed aloft.
"This supercell appears to ride an outflow boundary, which enhanced the updraft was able to keep it going for hours," Overton said.
Dying thunderstorm sends heat burst to town several miles away
As the decaying storm tracked south into Oklahoma, all the hot air started to plunge towards Earth's surface. The result was a heat burst which occurs when dry air inside a dying thunderstorm plunges toward the ground. Those outside at the time would say it felt like opening an oven.
A weather station in Cherokee, Oklahoma, recorded a spike in temperature from 90 to 103 degrees at 9 p.m. CDT. At the same time, winds gusted to 60 miles per hour. The humidity dropped from 61% to 14%.
"Just an absolutely incredible thing to see," Overton said.
Heat bursts need two things to form. First, there need to be dry and hot mid-levels of the atmosphere. Then, some sort of dissipating shower or thunderstorm is needed. They happen mostly during the spring and summer.
