I just made this. It starts around 1pm on Aug 2nd and ends at 24z, which I think is... 8pm?
Unfortunately, you can't see eastern Ontario. The supercell that develops initially was responsible for a tornado warning in Waterloo, Guelph, and Milton.
The second GIF came out North America view, it took almost forty minutes for the GIF to process, and I don't have the time to make a new version.
The second GIF picks up where the first one ends. I didn't know what time the severe weather ended, so I ball parked 9am, d'oh! So, it's very long in duration.
Enjoy!
