Textbook Microburst observed Tuesday evening!
While storm chasing on Tuesday evening near Springfield we were treated to quite a site. A microburst is defined as a small column of exceptionally intense and localized sinking air that results in a violent outrush of air at the ground. It is capable of producing damaging straight-line winds of more than 100 mph that are similar to that in some tornadoes, but without the tornado's rotation.
I drew arrows that show the downward motion of the air, and you can see where it slammed into the ground and was pushing/curling outward. Think of dumping a bucket of water on the ground... it crashes to the ground and splashes outward. Same thing here on a much larger scale!
I posted a video of the event here as well:https://youtu.be/MvOO0wMm0rU
