Storm motion doesn't seem to show enough eastward progression for Chicago to be in the path.

KWQC aerial footage showing train blown clean off its tracks and multiple homes damaged. It appears the tornado lifted for a bit and touched back down in the housing addition. Line now starting to bow out in central IL.

Helicopter video from Fruitland, IA, from WQADtv (www.wqad.com) shows a home completely blown off of foundation with only the basement remaining. We'll have to wait for the site survey from the NWS to see if that is a well-built home to qualify for EF3/EF4 damage.

I noticed what appears to be a tornado "debris ball" on a few of Scott's GR2A shots. Interesting, looks like we might have just a strong-violent tornado. Hopefully there are no fatalities.

Watching the live coverage from KWQC on their website. Some of their footage from Fruitland, IA, and Grandview, IA, shows trees that are stripped of all leaves and most branches.

Anvil canopy now moving in over my head. Line keeps backbuilding to the south, so at least northern sections of the Chicago metro will be impacted. Whether the storms will maintain intensity is a different question all together. They do have a habit of falling apart once they pass Dekalb, lol. Still, there is some good CAPE over Cook county. Yes, that lake breeze front could make things interesting. It is very evident on radar. Also, there may still be some trace of outflow boundaries from isolated activity of previous days, especially in northern Cook, southern Lake counties. A cell just south of Rockford showed a brief TVS on GR3, now just a MESO indicator, which disappeared as I was typing this. Southern end of the line looks like it's trying to become discrete. Chicago metro hasn't seen much severe weather besides the brief Schaumburg tornado a few weeks ago and a few wind reports in March/April.

NWS reports EF3 officially in Grandview and EF2 in Muscatine.
Ottawa IL storm showing signs of rotation, rotating wall cloud report on SN.

The Ottawa storm is moving into an area of maximized CAPE and EHI as it will eventually approach DuPage and Cook counties in the next hour. I'm thinking of moving to intercept as it gets closer. Still wondering what effect the lake breeze front will have on the storms. I would like to see some stronger winds out of the SE though.

The Ottawa storm looks interesting, on grlevel3 it shows some signs of rotation but has since fizzled some. The storm on its current track would be near my current location before 9pm. It will be entering a heavily populated area as well. i was looking at the mkx radar and the storms moved into the lake breeze and there was no noticeable effect.

It appears that this line will brush the northern edges of Chicago. Like you said David, it will be interesting to see what effect the lake breeze will have on the line as far as strength and storm motion. From the readings I can see, there isn't much of a temperature or moisture differential behind the boundary.
The back edge of cell H5 (2nd cell north) does appear to have some weak rotation. The LI in this area is -5.

EHI in this area is 1.0. CAPE is 1500 J/kg at the surface. There is a weak SE wind of 5-10 mph. It does look like the storms are sort of congealing into a line, which would make damaging wind the main threat. The tail end storm (V3) looks like it's trying to hook. The storm track markers place the damn thing over my head in just a few scans. I don't need to intercept, it's barreling right towards me!
A couple gusts of SE inflow at my location, Hoffman Estates. (right under the wavering lake breeze) Skies are darkening to the WSW

I can see the gust front out my front door now. I just went out and snapped a pic. A little stacked-plate action going on.
GRlevel3 is showing a new MESO marker on the tail-end storm, though it is weak. Just turned into a 3DC shear marker (orange donut) I'm surprised I can't hear thunder at the moment. SVR now in effect just SW of me for DuPage county.
Looks like they are becoming outflow dominant now.

Pretty explosive looking cell developed on the southern tip... came out of nowhere to 67dbz in two scans.
The outflow boundaries and the lake breeze are about to collide. Things could get interesting here.
EDIT: They do look pretty outflow-ish. What part of the city are you in David? I'm on the lake up by Loyola. I'm going to head to the beach in a bit to get some lightning pics.
