Chicago Storm Posted July 2, 2011 Share Posted July 2, 2011 If that is for Waukegen then yeah that is pretty obvious as to what that is... and there was a fairly good couplet at the time. The question is, whether or not this is on shore or off shore there. Based upon the locations of the boats in relation to the google maps imagery of Waukegen Harbor, this would probably be more NNE and close to shore but probably on land. The couplet was several miles offshore. This would have been associated with the RFD. Link to comment Share on other sites More sharing options...

If the couplet was several miles offshore as Chicago Storm says, then it's probably process of elimination. Link to comment Share on other sites More sharing options...
cyclone77 Posted July 2, 2011 Share Posted July 2, 2011 Latest 00z guidance fires storms south of our area later tomorrow. This is the 3rd or 4th CF passage in a row where our whole area gets skipped over. Getting a bit old. Derecho season fail for the QC so far LOL.

Chicago Storm Posted July 2, 2011 Share Posted July 2, 2011 gustnado? Quite possibly. Could have even been just dirt/debris being blown southward by the strong RFD. Add in that Waukegan Harbor gusted to 94mph too. A wider view pic would have helped in this case. Link to comment Share on other sites More sharing options...
cyclone77 Posted July 2, 2011 Share Posted July 2, 2011 If the couplet was several miles offshore as Chicago Storm says, then it's probably process of elimination. Looks like the OFB/flanking line stretched east/west along the shoreline there, so that would be a pretty reasonable location for gustnadoes just west of the couplet.

A wider view pic would have helped in this case. There was a waterspout that was reported E of Zion with that storm, this might be the waterspout that could have skimmed the shoreline as it trekked SSW.

cyclone77 Posted July 2, 2011 Share Posted July 2, 2011 I don't remember it being several miles off shore, maybe 4-5 at most at the point at which it was passing Waukegen. 4-5 miles is a long way off though relatively speaking. Either way the picture really doesn't reveal much. It's hard to tell whether that's blowing dust or actual condensation due to the lack of picture quality/distortion.

Yeah I removed my post after going through the radar briefing link that someone posted, for whatever reason I thought it was closer but it wasn't.

Powerball Posted July 2, 2011 Share Posted July 2, 2011 YAY!!! No cloud debris, but there's plenty of haze. We did have some passing cumulonimbus clouds a few minutes ago, thankfully it's giving way to some convective showers downriver and not here.

kevlon62 Posted July 2, 2011 Share Posted July 2, 2011 4-5 miles is a long way off though relatively speaking. Either way the picture really doesn't reveal much. It's hard to tell whether that's blowing dust or actual condensation due to the lack of picture quality/distortion. We have some friends who apparently were doing a fishing charter and did make it back in to Waukegan before this all hit. They took cover in the basement of one of the marinas. I don't know if this was their location. They lost the windshield on their boat and said there were several flipped sailboat. I'd say those high 75+ straight lines would have no issue doing all of that. I sent them the link to the pic and will see how they comment.

I'm assuming you're in Eastern Wayne county? I'm on the western fringe, and it's been either full sunshine or filtered sunshine most of the morning.
