This awesome image was captured by Canadian storm chaser Greg Johnson, to the South of Saskatoon in Saskatchewan, Canada yesterday evening. As you can tell by just looking at the picture, the storm was rotating strongly. The cell even had a radar-based tornado warning issued on it for a time yesterday evening.
Severe weather will threaten much of the same region in Canada this afternoon and evening, as well as adjacent portions of Montana and Idaho on the U.S. side of the border...
