2 areas of rotation on the Burlington cell

May need a warning for that area over Kirkwood

the SE IA disturbance is likely the trigger for the storms soon ahead  of it or within it...in these set ups, very high 0-3 km CAPE , sometimes mini sups may develop within it...watch for higher reflectivity cores  from DVN radar as a sign

If that is where our sups are coming from, storm it’s going to be a nightmare to chase.

I don’t see how the precip in central IL and SE Iowa won’t reduce this opportunity?. Seems that every chance we’ve had recently has been killed by morning convection.  Any thoughts around this?

That chunk of storms is hauling ass. We will see how it plays out, but they should be well gone in a hour 

69/64 in DKB with a sizable slug of storms to move through. Hopefully this won’t hold up the warm front, would like to see it push north of 88 for some hyper local chasing (familiarity of area/terrain) makes it much more enjoyable)

Going to head to Lasalle/Peru area later and set up shop. As cyclone said, good luck to everyone out and about today.

Have to see how the activity near the river beats up the atmosphere 

My bigger concern is the warm front getting hung up way south (as we have seen 1,000,000 times) and LOT ending up with boring rain and ruining a good local chase day.

As long as a huge MCS doesn’t blaze through, it should leave plenty of nice boundaries for intensification. 

10% hatched for northern up tornado probs. Been awhile since we have seen that.

Just using the Kankakee forecast sounding as one example to point something out... 

It's not one of those days with obnoxiously strong flow through the column, but it's certainly sufficient along with the nice CAPE.  This is a nicely sheared forecast sounding with good turning with height all the way into the mid levels.

It just takes one discrete cell to take advantage of that and we will have a big one. Likely will chase locally tomorrow. 

Good amount of damage in the Argenta-Oreana area in Macon county from last night. Luckily my parents had no damage, but quite a bit of large tree damage throughout town. May have spun one up pretty quickly along the line as it passed over Oreana. 

May be cycling. Last grab on velocity didn’t look as good. 

Iowa city is going to have a serious problem if this doesn’t cycle. Still a tight couplet 

Strong tornado tracking to Iowa city 

Full sun in RFD

New warning says confirmed tornado over Lewistown

Velocity doesn’t look great at the moment. May be cycling 

Hopefully this thing stays south of Lewistown. One of the bigger communities in that immediate area 

Cell near macomb will be heavily rain wrapped if it produces 

Rotation continues to tighten up on the Macomb cell
