Looks like it diffused and has been scooting around to my SE.

Have 1.76" rain in the bucket at post time.  Temp 74 with dp 73.  Not getting any winds except some breezes and no convection being picked up on the lightning detector.

IMO the tornado warning will not be extended after 10:30....seemed to damper a bit.
