Now we need to see whether any of them produce. Hopefully the ones in/near populated areas don't, while the ones out in open terrain produce spectacular but harmless tornadoes!

We've got a debris sig!! It's from that last velocity signature i posted. It was way more intense but disappeared as soon as i went to grab a pic. weird.

 

[Grand Poo Bah]

WOAH this is just to the northeast now!! Large debris sig. Both were unwarned

 

[Grand Poo Bah]

Another area of intense rotation. No debris sig yet.

I think you're right. My bad.

Lol all good, I think everybody's mistaken a strong mesocyclone or debris signature for clutter at least once lol

Here come the Illinois storms.

Reed Timmer just captured a shear funnel over his head (circled):

Neillsville storm starting to tighten up a bit more.

 

[Tennie]

The storms seem to be congealing (perhaps, at least) and the visibility is becoming grungy. This will pose a problem for tornado spotting.

Reed Timmer may have a tornado on his stream, but it's hard to tell for sure:
