This is a satellite picture of the storm system which produced the tornado I recorded.   This is an excellent shot of the bubbling effect of the clouds indicating strong updrafts into the atmosphere. The little bubble on the left is the actual overshooting of the storm over Arthur.  Remember that this shot is likely displaced about 15 km NNW in the image because of parallax in the view from the satellite.

Also notice the shadowing that the cloud tops have produced over Toronto indicating how high these clouds had rising into the atmosphere.
