Chicago Storm

The only thing is, this isn't a cool June. June is running +4.0 at ORD through the 14th.

First 90°+ day of the year on Wednesday at ORD and MDW, with a high of 91° at both locations. ...2026 90°+ Day Tally... 3 - ARR 1 - ORD 1 - MDW 1 - RFD 1 - PWK 1 - LOT 1 - UGN 0 - DPA

Ended up having a supercell quickly develop over DuPage County last evening, which then moved through ORD. There was a transient wall cloud at times with it as it approached from the southwest, as the storm interacted with an OFB and briefly tried to be interesting.

Janky LL lapse rates and a warm nose aloft will be the bullet in today in the favorable corridor.

sangamon county is in the watch. springfield can't be in the watch if sangamon county isn't.

Rapid recovery occurring across the southern half of the DVN CWA.

There's not a single 12z CAM that has a handle on evolution of the initial MCS.

Quite possibly. The latest HRRR already has a better handle, and never gets the WF back to even I-80.

I believe we will see some changes regarding expectations for today. Let the HRRR catch up to reality over the next few runs, and we’ll likely see a clearer and different picture painted.

it's a magical thing.

The forum will compress this picture to hell, but here was the view out of ORD as the line approached…

Peak wind gust of 73MPH at MDW.

Peak wind gust of 61MPH here at ORD.

the reverse jinx worked.

Numerous 70-90MPH wind reports in NE Iowa, NW Illinois and SW Wisconsin.
