Stormy Night in the Missouri Valley?

Looks like it. 

I took this photo of the thunderstorms approaching downtown Kansas City just a few moments ago.

AccuWeather regional radar shows the thunderstorms depicted above at right, new thunderstorms rapidly developing in Kansas' Flint Hills (center), and a strong cluster of storms in southern Nebraska (upper left).

Stay tuned. I believe there will be strong to, possibly, severe storms scattered over the area during the night.
