cyclone77 Posted August 11, 2020 Share Posted August 11, 2020 Power out here, going on 9hrs. Was in the QC all evening. Pitch black everywhere there too with pretty much the entire area still without power. Can't ever remember seeing such a wide expanse of damage. Usually after you have a severe storm when you drive around afterwards you come across areas hit hard, then go through areas where there's nothing. In this case everywhere you go there's significant tree damage and in some cases roads blocked off from trees and or power lines. This event will be hard to top. 1 2 1 Link to comment Share on other sites More sharing options...

The wind footprint from some of these derechos is sort of like a tropical system over land. Even though you generally don't get house flattening damage, the widespread area of substantial tree damage and low-moderate end structural damage is going to make this one fairly costly. 2 Link to comment Share on other sites More sharing options...

A-L-E-K Posted August 11, 2020 Share Posted August 11, 2020 Easily a top severe wind event for me, it went from relative calm to absolute peak so damn fast, every one of the large trees outside my office building came down at the same time as a wall of gray hit. 7 Link to comment Share on other sites More sharing options...

Did the wind start before, at the onset or after the rain started? For us it was probably five to ten minutes after the heavy rain that the wind really kicked in.

WestMichigan Posted August 11, 2020 Share Posted August 11, 2020 Pretty tame over here. Peak wind gust at my house was 33MPH. Would have loved to see the higher numbers, but I can do without the loss of power so I guess I am glad that we missed it. 1 Link to comment Share on other sites More sharing options...

wisconsinwx Posted August 11, 2020 Share Posted August 11, 2020 Raymond, maybe a few miles west of where UMB Wx and I were stationed, reported 5.8” of rain. It’s crazy but I’m not even that surprised with the way it came down (most of that would’ve fallen in an hour’s time). Link to comment Share on other sites More sharing options...

Our place is 1.8 miles from where we were and on my way home the ditches were pretty full and flowing good.. water flowing over the roads in a few places.. Yards with new ponds. Ponds in yards that were totally taken over and over its banks. Pretty bad. Our basement took on water but not terribly considering the conditions. 1 Link to comment Share on other sites More sharing options...
fluoronium Posted August 11, 2020 Share Posted August 11, 2020 This was a memorable storm for me for sure! When that PDS severe watch got issued, I threw all my gear in my car and headed up to the Oglesby, IL area. I pointed my car into the wind as it approached and enjoyed the show. The area took some serious damage and I encountered several roads blocked by downed trees and flipped semis on my way out. Unfortunately I bumped my dash cam into autofocus at some point so I ended up getting 50GB of macro footage of raindrops on my windshield. 3 2 1 Link to comment Share on other sites More sharing options...

andyhb Posted August 11, 2020 Share Posted August 11, 2020 Satellite image of the extensive blowdown in Iowa from yesterday’s derecho. You can see the tracks of the individual MCVs and bowing segments that enhanced the winds near/north of Des Moines, and then the US 30/I-80 corridors through Marshalltown towards Cedar Rapids and the Quad Cities. 3 1 Link to comment Share on other sites More sharing options...
dayton1996 Posted August 11, 2020 Share Posted August 11, 2020 Guys, The pics and videos really capture the intensity of that derecho. Fortunately, by the time the storms reached us here just south of Dayton OH, top winds speeds in my backyard were 47mph. Hope you guys stayed safe and didn't suffer too much damage. 1 Link to comment Share on other sites More sharing options...
