There are severe thunderstorms with intense lighting, many positive strikes coming from the tops of the clouds. This weather stretches across much of Texas from about SanAntonio to the Texas/Oklahoma/Arkansas border, and north into Missouri.

OP is probably seeing a fantastic light show if he is seeing it coming at him.

Looking at the satellite, maybe we will get some of it in Houston also. The area has expanded and looks to be sagging more south than it had been.

It must have been that rain dance I did earlier. LOL
