Central/southern part of the Chicago metro is getting rocked. Seeing a lot of 80-90 mph outbound bins from KLOT not too far off the deck.

The rotational couplet is slamming the south side of the city.  Too broad to be tornadic, but definitely local enhancement to the wind wrapping around.

Tornado in progress near Lucerne MO, TDS, report from Colin Davis.

[frostfern]

In have a feeling this line is going to do the GRR split thing that always happens.  

[andyhb]

Very reliable report here.

That’s a big tornado as well in a not great radar position. Probably a monster in there

[andyhb]

Via Clint Hendricks. Apparently became a large stovepipe and then a cone after this.

Hearing lots of damage in Ukie village & Chicago from blown debris and trees…

Assuming I am reading my UTC times correctly, this was pretty spot on with winds so far.

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

It's like an arrow of inky skies

Nice one, joe

Perfect skip over job here and the IL QC.  Next round likely to stay south.

Guess we'll see what happens with tomorrow's round.

My brothers tree took a lightning strike in Algonquin. Power is still out there as well 

[MazooWeather]

CAMS show a violent atmosphere in Western MI tomorrow night, if we don't get rained out could be a high end event for around here 

[sbnwx85]

Storms crapped out just before they got this far east which was expected. Gusts to 40 mph. Big show will be tomorrow.

Dry gust front hopped over MBY then cells filled in to the east while original line fell apart.  Rain screwed.

Do the CAMS have the complex developing from the current severe outbreak over N Missouri?  If that complex stays far enough south and weakens there should be a return flow behind it.  If it expands north overnight and rains all over the place instability will be trashed.

This thing moved in very quickly.  Temps dropped into the 60s here, so this thing is probably developing a cold pool.  Had a nice burst of 50mph winds and continuous lightning.

This.

Tons of power outages over here, but locally only had 30-40 mph gusts with about 5 minutes of heavy rain. No thunder here. Considering we were at 88/73° I’m surprised everything fell apart as it did. 
 

Eyes turn to the MCS over northern Missouri tonight. If that stays tame and south, tomorrow will be rocking around here. If it blows up and feeds off the nocturnal LLJ tonight and we end up with 2-3 hours of rain then tomorrow will end up a lot like today with more rotation embedded in the discrete cells.
