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.

The Northbrook air quality monitor is now reporting an AQI of 919.

Now 3/4SM FU VV019 here at ORD.

The sky is yellowing a bit now, solid pale/light yellow.

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

1SM FU VV020 here at ORD currently.

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.

Upper 80s imby and no headlines, miss north 

Wouldn’t surprise me if ORD or somewhere nearby briefly touches 100 today or tomorrow early afternoon. 
 
Models showing some nice dew point mixing during peak heating time today and tomorrow.
