I was gonna say, which office is holding out? 

 

Seems it could have been GRR and/or IWX, as they opted to go with a single watch over the whole area.

The GRR portion of the watch in particular looks iffy though.

[A-L-E-K]

right on the nose

Some casual 80+ mph bins over the south burbs

Yeah solid thunder here already. We’ll see how things hold together.

[MidwestChaser]

Wildest storm in a long time; massive tree damage here.

[SchaumburgStormer]

Looks like the southern burbs is getting their shit rocked by straight line winds

Can’t say I’m jealous of the destructive storms, but definitely jealous of the precipitation. My yard is crispy. Stay safe out there

Indeed; can see the footprints of where my kids have been playing and the grass is smashed down. 
 

but hey, gas is like $4.50 so at least we don’t have to mow. 

[CheeselandSkies]

As usual it takes the most annoying possible path. Rides the eastern fringe of the Madison media market. Not a drop here but we still have to be wall-to-wall for the tornado warnings.
