Seeing reports of light tornado debris falling in the Tulsa metro area again this evening, likely from the Moore area

The wall cloud rotating isn't a big deal there - it's what they do when they spawn tornadoes.

I've never seen an entire storm rotate like that, it's normally just the meso-cyclone that rotates making the tornado.

A rotating wall cloud is a visual indication of the larger mesocyclone. Storms as a whole will experience rotation, but the wall cloud is not the entire storm, for starters. It's the visual indication of the updraft area rotating, which is why tornados often spawn from rotating wall clouds. Non rotating wall clouds are not exhibiting surface rotation, so the updraft causing it is experiencing no significant rotation - meaning there isn't nearly as high of a chance of tornadoes spawning from it. Storm spotters will pay attention to wall clouds because they indicate significant updraft (necessary for tornadoes), but they do not pose a significant threat to spawn a tornado. They are really watching for rotation to be induced into the wall cloud (if one is present).

Okay, I was just saying I've never seen a storm rotate like that.

[EbylHusker]

Keep in mind that is time lapse, so you're seeing a far greater rate of rotation in it than you would in a normal video. But there is no question that a more violently rotating wall cloud would indicate a similarly violent rotation of the mesocyclone, and that would increase the chances of any tornadoes coming from it being very powerful. So considering how quickly the cell grew and dropped what increased to a monster tornado, it makes sense.

Tornado near Bennington, KS yesterday

It's pretty rainy here in Fort Collins. That's a good thing. Maybe there won't be any fires this summer.

Doubt it. Summer hits and it'll probably be prime kindling again. I feel like the greater Denver area has had wild fire issues the last 5 or more years.

True. Maybe "less" fires would be more appropriate

The Midwest is bracing itself today and tomorrow. Not a matter of if but where and when!

Storms already firing up in central and western Nebraska.

From everything I've been told or seen, this could be a long day/night of watching the radar!

For Lincoln, it will be tonight and tomorrow.

The storm chasers are massing down in Kansas and Oklahoma.
