Sounds like 3 CPR in progress north of Shawnee out of flipped cars per FF/EMS. Smoke eater are you hearing the dispatch

I've seen this supercell structure before a few years ago.

 

I'd give very high probs that this cycles soon

If that part by Dale develops it could drag straight through the area that was just hit.  Such a dangerous situation.

Yes sir, I'm relaying everything I'm hearing.

The storm environment is just ridiculous, clearly these clusters of storms are not only enhancing the synoptic environment and subtly backing the low level flow, but they are creating their own local highly enhanced environments. 350 m2/s2 of 0-1 km SRH is pretty much off the charts. 

 

Cumet basically has a perfect track record for calling these outbreaks. I will never doubt him again.

there is clearly a new circulation that has formed southwest of what was once that giant wedge that recently rain-wrapped...and now that cell on the west side is really getting its act together too

The original circulation seems to be getting a little better organized again.

The new Rapid Refresh V2 (currently not operational yet but available for use on SPC meso) has the locally enhanced 0-1 km SRH nailed.

We've had around 23 Tornadoes day... Seems like almost everyone of them has done some damage. And several tornadoes have done significant damage.

 

New Tornado looks like it's developing... Also looks like a Tornado is about to enter northwest Des Moines

RRV2 has been nailing it all day it seems. I've been impressed.

Whoa, you do remember that I backpedaled a bit this morning from the high risk talk right?  If anything, I'm slightly surprised at how violent these 2-3 supercells have been given the somewhat meager helicities being analyzed thus far, although the surface obs and the local effects that you mentioned suggest that the mesoanalysis and HRRR forecasts have their flaws.

We were just watching the northern ones. One got tor warned about 25 mi NE but we didn't follow. May check the southern one if it starts looking better. The middle one is lame.

Echo tops are continuing to increase as it looks like this storm is going through a cycle and is going to ramp back up again.

The more problematic part staying north of DSM. Mostly hearing it's a severe wind event and hail but some reported rotation recently but nothing on the ground.
