kevlon62 Posted July 16 Share Posted July 16 Just before the main line moved in to O'Hare, etc., it was interesting watching that outflow boundary push to the southwest through northern Cook County, extending southeast toward downtown, from the cells that had fired in the northern tier counties and moved out over the lake.Brother out by Des Plaines was in the backyard and commented how much cooler it felt just after that feature pushed through.We figured it would stabilize things some - perhaps the confluence points with the main line ended up being evident with that Bensenville/O'Hare spin up area, along with that rotation just west of downtown over 290.Interesting to think how things would have gone had that boundary not pushed inland - perhaps less/perhaps more effects say I-290 north.Separately, saw some scattered tree damage this morning a few blocks north of Bensenville but nothing too crazy. 2 Link to comment Share on other sites More sharing options...

mjwise Posted July 16 Share Posted July 16 Looks like the biggest wind occurred in a Kewanee to Camp Grove line. There was a measured 105 MPH gust in that area and reports of at least one blowdown of a corn field. Glad we didn't get that up this way. Link to comment Share on other sites More sharing options...
CheeselandSkies Posted July 16 Share Posted July 16 Pretty substantial structural damage at a supper club and a few nearby buildings near Kieler, WI. Wouldn't be surprised if that turns out to have been a brief but strong spin-up. Also at work we have viewer-submitted video of what certainly appears to be a tornado (although it wasn't tagged as "confirmed" at the time) near Evansville (same town that was affected by the record-breaking early February EF2).

KeenerWx Posted July 16 Share Posted July 16 Fairly widespread tree damage across at least the northern portion of my county (Jasper). Lost a fairly mature tree in my own yard, but luckily didn’t hit the house or anything of consequence. Link to comment Share on other sites More sharing options...
Stevo6899 Posted July 16 Share Posted July 16 Nice mini derecho that rolled through here this morning, with easily 60 MPH gusts. Luckily not too much damage. Id guess we've had over 3 inches of rain here the past few days. Never seen the grass so lush in the middle of july. 1 Link to comment Share on other sites More sharing options...

Obviously the dynamics weren't the same as they were with the complex back in the Chicago area, but anytime storms roll through in the dark, I get nervous.

CheeselandSkies Posted July 17 Share Posted July 17 Kieler damage was indeed an EF1 that touched down for 1 minute (so not as strong as I thought). Evansville not confirmed despite how low to the ground the funnel looked in the video. Link to comment Share on other sites More sharing options...
cyclone77 Posted July 17 Share Posted July 17 DVN confirmed an EF-1 tor tracked right through the heart of the QC, from Davenport/Bettendorf across the MS River to East Moline. Link to comment Share on other sites More sharing options...
Chinook Posted July 17 Share Posted July 17 Comparisons of the Super-derecho of June 29, 2012 to the derecho/severe event of a couple days ago. Obviously, the storm of a couple days ago did not continue much toward Ohio or the East Coast. So, a huge difference there. Somewhere back in my distant memory, I think I saved a SPC mesoanalysis of 9000 J/kg of MUCAPE on the night before the super-derecho (June 29, 00z) but I can't seem to be able to prove such a high value existed. The archived ILX shows 7481 J/kg in the morning. So, yeah. Mega-CAPE Mesoscale discussion from June 29, 2012 a couple of days ago 1 Link to comment Share on other sites More sharing options...
CheeselandSkies Posted July 18 Share Posted July 18 Here in Madison we were on the very northern fringe of Monday's complex; no severe weather (and barely any rain, which is fine given how much we got in the preceding couple of days) but like on June 24th, the setting sun combined with the departing storm clouds illuminated the whole sky pinkish-orange, as intracloud lightning flashed. Some people with a view to the east even caught the lightning with a large, horizon-spanning rainbow. 5 Link to comment Share on other sites More sharing options...

Chicago Storm Posted July 18 Author Share Posted July 18 So, now that I have some time... Monday night's shift at ORD was top tier, right alongside 7/12/2023. There were numerous power flashes to the W-WNW, as the activity approached and then hit. The peak wind gust at ORD was 75MPH. However, there was not much in the way of damage, due to the lack of trees here at the OBS site. I know there were reports of a tornado over the airport field, but there was nothing that was visible nor any other concrete evidence that one was occurring/occurred. There was a brief moment of erratic winds, but that doesn't' necessarily mean a tornado. Back home in North Naperville, destructive level damaging winds impacted the area. The preserve across from our apartment was hit hard, as well as down into North Naperville. Across this area, uprooted and snapped trees are widespread, in addition to widespread tree limbs downed. Straight-line wind damage in this area is likely in the 70-90MPH range. I made sure my wife was out on the balcony when the action hit, and she said "It was windy". Yea...a bit. I then spent all of Tuesday and part of Wednesday with @RCNYILWX surveying out in the West/Southwest Metro, where we confirmed three tornadoes. 12 Link to comment Share on other sites More sharing options...

Chicago Storm Posted July 19 Author Share Posted July 19 The EF-1 tornado from Monday evening that extended from the near West Side to downtown Chicago is the first tornado inside of downtown Chicago since 1876. An F3 tornado occurred on May 6th, 1876. 2 Link to comment Share on other sites More sharing options...

Got mine heavily into weather after last years EF-0 hit within a quarter mile of my house. Now she’s always trying to figure out when the next severe weather event is.

sbnwx85 Posted July 19 Share Posted July 19 Confirmed tornado from earlier this week in Elkhart. Lots of trees toppled onto homes. No injuries or fatalities. This is only about a mile from where I grew up. Amazing to see virtually no damage outside of the tornado path... and tons of tree damage within this neigborhood.

CheeselandSkies Posted July 19 Share Posted July 19 Evansville from 7/15 now confirmed as a 1.23-mile EF0 path. https://www.weather.gov/mkx/wisconsintornadoes We've now edged out 2021 as the busiest year for in Wisconsin out of the last 11. Still behind 2010 with 46, and 2005's record of 62 is probably safe barring a surprise August outbreak (which is also what put that year so far ahead of everything else). Still haven't had one rated EF3+, though and the longest track by far was Evansville-Lake Koshkonong on, go figure, February 8th. 1 Link to comment Share on other sites More sharing options...
CheeselandSkies Posted July 22 Share Posted July 22 GFS has been teasing the next possible uptick in severe potential for the Midwest for the end of the month for a while now. Modest to moderate WNW to NW 500mb flow over 70s dewpoints. Signal is still there as of today's 12Z run, but it's still 7-8 days out so obviously much TBD regarding timing, location, mode and ceiling of threat.

SPC starting to come on board: Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0346 AM CDT Tue Jul 23 2024 Valid 261200Z - 311200Z ...DISCUSSION... Upper ridging will spread across parts of the Plains and eastern states, while the subtropical high develops westward over the southern tier of the U.S. during the Day 4-8/Fri-Tue period. This will suppress severe thunderstorm potential for much of the CONUS. The exception will be a potentially more active period for parts of the northern Plains into the Upper Midwest due to a series of upper shortwave troughs migrating across the Canadian Prairies and parts of the northern Plains/Upper Midwest through the forecast period. 1 Link to comment Share on other sites More sharing options...
