A-L-E-K Posted June 14, 2022 Share Posted June 14, 2022 1 hour ago, Possum said: Whew. Last night snuck up on me in Humboldt Park. I had all of my friends/housemates who live upstairs come down to the basement when the sirens started going off, and immediately after that they issued the updated the tor warn with my house in the center of the polygon’s path. I’ve only lived in Chicago for 6 years but seeing that couplet turn right and make a beeline for my neighborhood was the most scared I’ve felt here. Luckily the rotation kept turning right and passed us to the south, and once we were out of danger the storm was extremely enjoyable. We all went out and sat under the sunroom porch to watch the lightning show as the storm passed to the southeast. Had several very close CG’s no more than .2 miles away where the flash and boom were almost simultaneous. Easily the best thunder and lightning I’ve experienced here. Even had a few dime-sized hailstones. No damage to my house or garden, and I’m glad for the .44” of rain we got to help my plants get through the 100 degree heat moving in today. Overall it ended up being a great storm, crazy to consider how easily it could’ve been a tragedy. nice report, don't be a stranger 2 Link to comment Share on other sites More sharing options...
frostfern Posted June 14, 2022 Share Posted June 14, 2022 Its frustrating how the most significant severe events near me have targeted unchaseable zones and populated areas. First Gaylord Michigan, then metro Chicago. 1 Link to comment Share on other sites More sharing options...

Hoosier Posted June 14, 2022 Share Posted June 14, 2022 Just a couple other random obs about yesterday. I noticed a constant gentle thunder for a good 20-30 minutes before it arrived. It seemed like there were practically no breaks to it. Anyone else around Chi metro notice that? The other thing was the sky. It went from gradually getting darker to an absolute death look with some yellowish tint mixed in a couple minutes before the winds it. I can't say that I saw a funnel at any point, but there was some funny looking stuff. I was outside and not constantly checking my phone for radar at that point, but never strayed more than a few feet from the door in case I'd have to run inside fast. 3 Link to comment Share on other sites More sharing options...

I heard that type of thunder while chasing a hailer in Allegan County, MI on April 7, 2020. It was after dark and there were almost no breaks in the lighting. It was a constant strobe. That was after dark though. It would be amazing to see video of that Chi metro cell from the air. If any planes were coming into O'Hare they would be circling waiting for it to move. Sometimes you see more lighting from a distance, or even from the air, as a thick low updraft base tends to obscure a lot of the intracloud lighting. It's always really hard to see the full structure of a beast HP cell with a super low base just because it's so big and low to the ground. 1 Link to comment Share on other sites More sharing options...
sbnwx85 Posted June 14, 2022 Share Posted June 14, 2022 I had to work in the newsroom during the storm, but snapped this photo of the orange-tinted sky as the storm departed during sunset. I was lucky to keep my power. I saw winds around 50-60 mph with some pea-size hail. 3 Link to comment Share on other sites More sharing options...
Hoosier Posted June 14, 2022 Share Posted June 14, 2022 This tidbit from LOT's event page: This storm had an impressive depth, with a top over 60,000 ft based on data from multiple radars, and may have been over 65,000 ft to near 70,000 ft. Radar beam widths and heights at such a high elevation become very wide, so it's difficult to say a specific height. No matter what, this storm was in the upper echelon of storm tops for mid-latitude, non-tropical thunderstorms. Link to comment Share on other sites More sharing options...

No matter what, this storm was in the upper echelon of storm tops for mid-latitude, non-tropical thunderstorms. No wonder it looked like a volcanic eruption plume. I wonder where the record would be for the tallest cloud. Tropical cyclones in the strengthening stage often have the highest uniform cloud tops, but there is little or no overshoot. I have heard that supercells that occur over the eastern Indian subcontinent are exceptionally tall. Link to comment Share on other sites More sharing options...

Hoosier Posted June 15, 2022 Share Posted June 15, 2022 Public Information Statement National Weather Service Chicago IL 620 PM CDT Tue Jun 14 2022 /720 PM EDT Tue Jun 14 2022/ ...NWS Damage Survey Results for 6/13/2022 Severe Event... An NWS damage survey team investigated damage in parts of Cook and DuPage counties that was caused by a severe thunderstorm that moved across the Chicago metro during the late afternoon and evening of Monday, June 13, 2022. It was determined that a brief EF-0 tornado touched down in unincorporated Schaumburg and moved into Roselle before lifting. Additionally, it was determined that strong straight-line winds of 70 mph or greater caused widespread tree damage in Streamwood and across a large swath of west central Cook County, with winds as high as 90-95 mph also causing structural damage in the communities of Bellwood and Westchester. .Schaumburg-Roselle EF-0 Tornado and Straight-Line Winds... Rating: EF-0 Estimated Peak Wind: 80 mph Path Length /statute/: 2.2 miles Path Width /maximum/: 25 yards Fatalities: 0 Injuries: 0 Start Date: 6/13/2022 Start Time: 6:27 PM CDT Start Location: 2 S Schaumburg Start Lat/Lon: 42.0016/-88.0813 End Date: 6/13/2022 End Time: 6:32 PM CDT End Location: Roselle End Lat/Lon: 41.9747/-88.0606 An NWS damage survey determined that a brief tornado touched down in unincorporated Schaumburg, crossed the Elgin-O`Hare Expressway into Roselle, and lifted just prior to entering Medinah. Damage was sporadic along the tornado`s path and was confined to trees. Just west of the tornado`s track, a wider swath of straight-line wind damage associated with a rear flank downdraft wrapping around the tornadic circulation was observed. These winds were estimated to be as strong as 75 mph and flipped over a small plane at Schaumburg Regional Airport in addition to causing widespread tree damage on the far southern side of Schaumburg through much of Roselle. .Streamwood Straight-Line Winds... Estimated Peak Winds: 70 to 75 MPH Fatalities: 0 Injuries: 0 An NWS damage survey determined that widespread tree damage across Streamwood was caused by strong straight-line winds of up to 75 mph. These winds were associated with a rear flank downdraft that wrapped around a strong low-level circulation within the parent supercell thunderstorm. .West Central Cook County Straight-Line Winds... Estimated Peak Winds: 90 to 95 MPH Fatalities: 0 Injuries: 2 Between an NWS damage survey and information provided by local emergency management agencies, other government officials, and trained weather spotters, it was determined that structural and tree damage observed across a large portion of west central Cook County was caused by a swath of strong straight-line winds. An 84 mph wind gust was observed at O`Hare Airport, and winds as strong as 95 mph were experienced farther south. Notable structural damage included roofs getting peeled off of apartment complexes in both Bellwood and Westchester, and an office building in Westchester having multiple windows blown out. Two injuries were reported in the Bellwood apartment complex. Widespread tree damage was also noted in the suburbs of Bensenville, Bellwood, Maywood, Westchester, Broadview, La Grange Park, Brookfield, Riverside, Lyons, Stickney, and other nearby areas. && EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0...Weak......65 to 85 mph EF1...Weak......86 to 110 mph EF2...Strong....111 to 135 mph EF3...Strong....136 to 165 mph EF4...Violent...166 to 200 mph EF5...Violent...>200 mph NOTE: The information in this statement is preliminary and subject to change pending final review of the events and publication in NWS Storm Data. The NWS greatly appreciates the help from local spotters, emergency management officials, and fire department officials who greatly aided in the damage surveys for these tornadoes. $$ Baker/Bardou/Doom/Lincoln/Ogorek Link to comment Share on other sites More sharing options...

Always love flying around thunderstorms, to see a storm twice as high as you at cruising altitude is a purely intimidating thought.

Didn't we have one of those in 2020? Both in terms of an actual warm-core low (Cristobal) moving through, and then the 120-140 MPH gusts with the derecho in August?
