Ouch Wonder how many millions lost power from this.

Public Information Statement National Weather Service Northern Indiana 246 PM EDT Tue Aug 11 2020 /146 PM CDT Tue Aug 11 2020/ ...NWS DAMAGE SURVEY FOR AUGUST 10, 2020 TORNADOES... Two tornado tracks were identified through storm surveys conducted on August 11. .TORNADO 1... Rating: EF-1 Estimated peak wind: 110 mph Path length /Statute/: 2.5 miles Path width /Maximum/: 100 yards Fatalities: 0 Injuries: 0 Start date: August 10, 2020 Start time: 6:32 PM EDT Start location: 6 miles SW Wakarusa Start Lat/Lon: 41.5079 / -86.1238 End date: August 10, 2020 End time: 6:37 PM EDT End location: 3.5 miles SW Wakarusa End_lat/lon: 41.5076 / -86.0755 SURVEY SUMMARY: The tornado began west of the intersection of Riley Rd and Dogwood Rd in southeast St. Joseph County. It then tracked along and south of Riley Rd. Widespread tree and structural damage occurred through this path. Grain bins were toppled and farm outbuildings sustained significant damage. The tornado tracked through several cornfields that resulted in significant crop damage. The tornado lifted just east of Beech Rd. .Tornado 2... Rating: EF-1 Estimated peak wind: 90 mph Path length /Statute/: 1.5 miles Path width /Maximum/: 100 yards Fatalities: 0 Injuries: 0 Start date: August 10, 2020 Start time: 6:56 PM EDT Start location: 0.75 miles N North Webster Start Lat/Lon: 41.3360 / -86.7020 End date: August 10, 2020 End time: 6:59 PM EDT End location: 1.2 miles E North Webster End_lat/lon: 41.3271 / -85.6752 Trees were snapped west of State Route 13. The tornado then crossed SR 13, resulting in a notable path of trees snapped and broken limbs. These debris were scattered throughout a nearby church parking lot. The church sustained a loss of roof covering. Additional areas of tree damage were noted farther to the east- southeast. Some homes sustained damage as a result of falling trees and branches. The tornado then crossed out over Lake Webster and dissipated. 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 event and publication in NWS Storm Data. $$ Brown/T

So true. 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.

Nice one overall. Impressive corridor of higher end wind reports from IA into IL.

One of the aforementioned Rogers Park vids

Yeah I saw a couple vids. One from closer up as it moves out into Lake Michigan and the other from a bit farther away in which you clearly see debris being lofted.

Appears there may have been a quick tornado in Rogers Park.

Leading edge was not super intense but enough to knock down some small-medium size branches. Now getting some of those gusty bursts.

Could move in here or very close by if it holds together.

Sun is back out here.

Really impressed by the reports of the duration of the winds. One thing to get the big gusts through quickly but another to have it last a while.

Almost need a short fused high wind warning

If they don't upgrade to high risk at 20z, I would attribute the reason to the background synoptics not being higher end. But that hardly matters at this point with a well developed/established convective system and good maintenance parameters downstream.

Agree. I was thinking back on August derechos specifically in the past 10-20 years, and this one looks like it has a chance to be at or near the top of list. A lot of extracurricular activity happening on the streets of Chicago and even spilling into northwest IN. Hopefully people who are outside are aware of the wx situation later.

I remember the old school high end severe thunderstorm warnings where they would mention "siren activation is suggested" in times like this. Don't know if any offices still do that, but this is the perfect type of situation for it.

Not a whole lot of negatives with this setup. Really liking the potential, and added bonus for occurring during daylight.

New thread for today's severe weather:

Ok. I don't know what the hospital situation is like in Michigan, but if the numbers are good then maybe one could argue for limited opening of some of those places. Hopefully some good can come from all of this and people use it as an opportunity to try to get their health in check as much as possible. I supppement with vit D (especially in fall/winter when you can't really get adequate sun exposure), magnesium, and zinc for general health and to maintain healthy T levels. Been doing that long before covid came along but if it would help against that in some direct or indirect way, great. We have a ton of obese/morbidly obese people walking around in this country, which obviously doesn't help if you contract this virus. I check off a couple of the risk factor boxes myself... and they are not necessarily readily apparent when you look at me. I have been operating under the assumption that whatever I had in March was not this virus and am continuing to avoid higher risk situations to the best of my ability. Still have not physically been inside of a restaurant since February. I agree with the thinking that a majority of us will catch it (with many not realizing they had it) but my philosophy has been to try to delay it as much as possible. You never know if catching it down the road could alter the course of your illness (particularly for someone with one of the more severe cases if better treatment comes out) or possibly even save your life.

What is still closed in Michigan? Here's where we are in IN. Click the image if the print is blurry. We have been in what's called stage 4.5 for a while and my guess is it will probably be extended past August 27. Basically everything is open (or at least allowed to be open) with certain things at 50 or 75 percent limits.

I think both places got the nursing home outbreaks under control. In general I know Sweden has had a more voluntary approach in dealing with the virus.

Really comes down to how much virus they are willing to tolerate. The infection rate there is low enough right now that it wouldn't surprise me if it takes a while to reseed enough for a big increase, but the counter to that the numbers can take off quickly in such a big city.

NYC schools opening may be beneficial in a way. Since that area had more widespread infection than the rest of the country, it may give a better idea of how prevalent that getting reinfected is. So far you hear some anecdotes here and there, but we should start hearing a lot more stories if immunity tends to wane within months.

After getting ravaged in the winter/spring, NY did a good job in beating it down. They have been running like 1% positivity rate there for quite a long time I think. It is the right decision to open the schools there, but obviously have to keep an eye on the data. Given what they went through, I would think they will have a hair trigger there if it trends too far in the wrong direction.

Bad timing as hardly any schools have reopened yet, outside of a district here and there. I saw that Chicago public schools will be doing all virtual learning. That will help keep the Illinois numbers lower than they would have been. Will be interesting to see what happens as we get into the fall and winter. There has been much speculation about the "2nd wave" as the seasons change. I think there is some merit to that, but a lot of the case trends with this are driven by how open a particular state is. Most states are going to be having in person schooling at least in parts of the state, so imo that additional "reopening" will be what sets off a 2nd round in areas that are currently at low levels.

Record daily number of confirmed cases in Indiana. Of course the positive percentage is important to look at as well. That has been hovering in the high single digits. Some states have gotten down to 1% or 2% positivity rate. Never really got it down as far in this state, but otoh, didn't spike as bad as some others. Been more of a slow to moderate burn.
