April 29th took us to central/northern Kansas to play a boundary. Moisture was not optimal that day, but lift and shear were great. A supercell formed southwest of Cuba, Kansas and looked pretty respectable. It had a decent non-rotating wall cloud for a long time. Finally as it moved north of Washington, a new lowering started spinning rapidly, eventually putting down a brief tornado as it came directly overhead blasting us with strong WARM RFD winds. The wall cloud passed directly overhead giving us a moment of intensity hoping it would not drop a tornado until it passed us. It was on the ground off and on for about 3 minutes before dissipating.
