We're under a warning for possible cold-core funnels now. Not as dangerous as a tornado but could do damage if they were to touch down (they rarely do)

I never heard of that before..what is a cold core tornado. Cold in the middle? What causes that?

Cold core funnels aren't tornados. They form when the air is cooler vs tornados that form when the air is hotter. A tornado will almost always touch down, whereas the cold core funnels usually don't - they are smaller and stay high in the sky. On the off chance they do touch down, it's like a nasty wind.

Ahhh, good to know. Thanks
 
There was a tornado in Grande Prairie maybe fifteen years ago. There was also the huge one that hit Edmonton in the 80's(?). I don't know why they hit there. As you say, not common.

We usually had at least a funnel cloud, which doesn't touch down, each summer. The humidity and heat plus cold fronts make perfect conditions for tornadoes and similar storms.

Pine Lake tornado 25 (?) years ago...by Didsbury LAST summer
 
Another weather item to try to remember! A while back we started hearing about plough winds, which nobody seemed to have heard about before. I have now seen what one of those can do. Just hope it hits trees and fields, not anything financially important.
they can be more destructive than a funnel
 
A tour 'n shroud? RIP ouris ... a dash ... there is a miss in Niagara like that ... gone in a cloud! Some would swear that Shenandoah is real ... when only a morn 'n vision ...

Sometimes in the morning when shadows are deep, I lie here beside you (pondering tales) ... things that trail off the NU's ... like oh' δ ... oozing along the valley cut! Freudian vapor as a dream ... there it was gone ...

I was in London, ON some years ago. It started to rain before we headed into the downtown mall (which was still nice back then) to watch a movie. The windows on the roof looked like they were under Niagara Falls. When we came out a couple hours later it looked like a war zone. Apparently it wasn't a tornado but some other wind that was like a horizontal tornado. It was quite disturbing.

We've had some doozies even not counting the occasional tornadoes we get. That derecho that went across Ontario in 2022 wrought some havoc around here.

Those are the plough winds or I've also heard them called straight-line winds - very intense, very focused. We do get a lot of those in Alberta - that's what took the stage down at Big Valley Jamboree a few years back and destroyed the barns at the Millarville Racetrack by Calgary
