UFO Sighting in Hamilton, Ontario on 2017-05-30 20:02:00 - Disc shape cloud moving amongst storm clouds

Disc shaped cloud appeared to keep shape. you will notice in last pic that it is in front of a tree top that has to be 20 feet off the ground. the clouds were higher then that. it is an interesting anomaly. i saw a lightening bolt while sitting near the mall. it went around in a spherical fashion like it was around a saucer shape in the cloud. i found that odd the formation of the lightening bolt. just an observation
