It is not geographically or physically possible for both a funnel cloud to form and tornado touch down City proper, in Cook County. The news does this every year for ratings, they lie. All the headlines say tornadoes were “reported” but you will not see an image of one, because there weren’t any.
You are right about the city proper. Too much density.
But, there were def tornado-esque situations on radar. The scary one being at O'Hare because the lapses in density that provide space for said airport would contribute to formation, though I don't believe there is enough time with a storm moving so fast, but the suburbs def provide space and a tornado moving is would not be outside the realm of preparation.
The warning systems are based on that modeling of the storm. Really, an abnormal number of spots in the storms looked like, moved like, and was all but a tornado as they either didn't sustain formation. The possibilities are always there and yesterday's storm was pretty scary as we don't historically carpet the entire city in a tornado warning. Again, the storm certainly had the fuel, it just didn't have the space to commit.
To put some perspective on it, as soon as the storm went into Indiana there were more people-verified debris clouds with these formations.
I saw more downed trees and what not this morning. just like yesterday, but there wasn't a lot of rain like they predicted. I was outside around 10pm last night and I was able to have the car windows down cuz it was barely raining and quite pleasant temperature wise.
The storm front was quite small.
Probably like a 10 minute window realistically for any type of chaos. Overall, the panic zone was about 9:40pm to 10:10pm. Abut a half hour after that the bulk rain area was pretty much gone. Small, but very potent storm.
The biggest concern is the winds. 95mph reading at O'Hare.
