Odd Severe Weather Summary for July 30?, 2017 for NW QC

This is an unusual one. It is stamped 10:47 this [Monday] morning, but it mentions severe thunderstorms occurring on that Monday afternoon. I checked the French version and it has the same error.

Ruling out the possibility of EC inventing time travel, I believe that this actually occurred on Sunday, July 30 at around 6 pm according to the little AWOS data available at Parent.
