Have watched this for several years now. There is nothing that would create this like a radar sweep. Ojai California has been the site of hauntings and a rumored Dimensional Vortex doorway out of the world. I cannot explain this, let me know what you think. I decided to take my camera and film this for you. A perfectly round circle highlighted against storms. I used both the MyWeather and 1Weather app radars to verify the app wasn't at fault and it is not.
