While multiple rounds of severe t'storm activity occurred across the area yesterday, the most notable at ORD was the late afternoon round.

ORD had a peak wind gust of 64MPH with outflow that moved through ahead of that particular round of activity.

Chicago dodged what likely would've been its hottest day of the year thanks to today's storms. Rockford and Madison reached the mid-upper 90s under plenty of sun, and even Detroit ended up warmer. Pretty unlucky (or lucky) depending on how you view it, and also a really bizarre set-up.

The thermal ridge was north.

It's very doubtful that ORD would have topped the current highest of the year, which is 96° (7/14).

It hit 92° at ORD and 91° at MDW yesterday.

It’s nearly pointless to post this given the compression, but… A view from ORD just before sunset this evening.

Edit: Amazingly, the compression isn’t horrid.

New peak of the day, with 1/2SM FU VV015 here at ORD.

Even with the smoke and a wind off of the lake, both ORD and MDW hit 91° today.

Secondary lake breeze that moved through is helping to pull more smoke in.

luckily looks like the real high grade stuff should stay east of mby

This is the worst it has been for our area.

There's gonna be some record AQI’s.

Smoke is quickly moving into far NE IL, as this back-door front moves in/through.
