Wow, the 12z NAM has much less rainfall for most of OH than the GFS does, inside 48 hrs (48 hr total.) The NAM has 0.1" Columbus, 0.2" Cleveland. I wonder which will be right. Obviously this has implications for drought relief, and the possibility of localized flash floods.

It could be one of those situations where the heavy rain won't be widespread, but the areas that luck up under the pop-up t'storms get a nice dosing of it.

A Hi-Res model like the NAM would obviously be able to depict this outcome better than the low-resolution GFS.

Yeah that's probably erroneous.  Initially wondered if maybe it was something over the lake but the 5 miles northeast in the ob is a point that is still over land.

Well hell, it's actually legit.  How about that?

Pretty cool how the weather can throw a surprise curveball every now and then.  FWIW, I did some research into Chicago tornadoes some years ago and the ones I found were of the traditional thunderstorm type, so this particular occurrence is probably a first of its kind (at least documented) in the Chicago city limits.

That was exactly our thoughts. Still amazed it happened. We were completely caught off guard when the observer reported FC in the METAR because would never have expected a landspout to occur in that environment.

Some incredible photos surfaced from Willis Tower:

Yeah, still shows you how strong of pattern we are in that even a day where it is partly to mostly cloudy still gets 90.

Temp profiles support 4 more 90*F+ days, but that's obviously going to depend on the extent of cloud debris / convection.

This is looking like the dirtiest ridge we've seen all season, so there will probably be better chances for rainfall to affect high temps.

Awesome pic! Was doing some research on landspouts and found out that some strong ones can do EF2-EF3 type damage? Is that legitimate?

Nice pics.  I noticed you guys don't have a path length in the LSR.  Was it basically stationary?

We don't have anything else to go by other than the photos and no damage reports yet. It did appear nearly stationary from the video taken by a motorist on I-55 posted as a comment on the Illinois Storm Chasers Facebook page.

Sweet pics on the landspout. Crazy how that happened.

Flash Flood Watch for tonight into tomorrow. 2-3" per hour expected with some spots receiving up to 6" totals. MN as a whole had the 3rd wettest July ever and now August is following suit. The grass never even browned up here this summer. I doubt it's going to at this point. Insane rains the last few months.
