Inspired by my recent publication via Andrews McMeel Publishing, I thought I’d revisit the amazing Watonga Supercell. Photogenic storms are rare on the Southern Plains in August. This storm developed on an outflow boundary created by storms the previous night/morning. It was stationary for an hour due to light upper air flow. CG production (cloud to ground lighting) was such that I dared not leave my vehicle. The storm rotated in place until a bowing line of storms wiped it out from the west. Images below chronologically describe the event. A brief mesoanalysis is included for those who are meteorologically inclined. The Watonga Supercell will always be special to me as it also resulted in my first supercell time-lapse movie included below.

500 mb Map; Paltry 15 kts in western OK explains why this storm did not move for an hour. Radar Image; See the line of storms to the west that ultimately wiped out my stationary supercell.
As mentioned above the Watonga Supercell will always be special to me as it also resulted in my first supercell timelapse movie. Shot way back in 2009.
