CALGARY -- We’re going to lead in with yesterday’s activity. Isolated storms with a significant rotation produced a shelf along with loonie-sized hail to the city’s extreme northeastern outskirts. As an aside, thank you so much to the several dozen viewers and CTV Calgary Skywatch App users who sent in some amazing photographs. We’re bringing the photos of the day up to give you an idea of the storm as it was, with emphasis on the last image:

Thanks to Jen, Diane, Kathy, and Jeff for those pictures, and to Rai for this one, which gives us a great look at scud:

Scud is warm, moist air that rapidly ascends, cools, and condenses into a wispy, scattered cloud along a storm from. That’s what’s just to the left of the lightning, and therein could be confused with a tornado; coupled with the tight rotation from this storm system, there was absolutely reason for Environment Canada to issue their warning. Whether or not that will be confirmed today, is another story entirely.

On to the forecast!
