Update: 7:45pm. Sure enough, a downburst near Goddard, KS a west suburb of Wichita.
On conventional radar, we often speak of thunderstorms with high microburst potential as being "all core" (the red part). The Goddard cell certainly qualified.
Here is a photo of the towering cumulus clouds over Wichita at 7:10pm CDT.
Here is a view of the radar at 7:24pm as a meteorologist views it in this situation. There are three boundaries over the area which are favored locations for the development of storms. If they develop, strong downburst winds are possible. I'll post later this evening and let you know what actually happened.
