Will update as surveys are completed...
 
I wouldn't be shocked if that was upgraded to F4. Time will tell. I did see some very impressive damage images over the past 12 hours.

Certainly was an incredible storm...long tracked Wisconsin Supercell. Looking through the Significant Tornado book one would gather that this is one of the more impressive August outbreaks for Wisconsin.
 
No mention of the QRT that's dispatched for tornado damage assessment that appears to be of the violent nature (F4-F5).
Pretty sure there is no funding for the QRT any more due to the present NWS fiscal situation. I'm on the QRT, along with Don Burgess, and we just discussed this this morning. No calls all year for us. That's not to say they may have called other members (there are 20 in all).
 
Some research, I did on F3, F4, and F5 tornadoes in Wisconsin for August.

F4 Tornadoes in August: 1950-2004 for Wisconsin:
08-22-64 F4 Ozaukee County, 30 injured.
08-19-68 F4 Marinette County, 2 killed, 3 injured

F3 Tornadoes in August: 1950-2004 for Wisconsin:
08-16-63 F3 Columbia County, 13 injured
08-02-67 F3 Dane County, 2 killed, 5 injured
08-29-92 F3 Washara County, 1 killed, 30 injured
08-23-98 F3 Door County, 2 injured

For some reason, COD text products links to individual text messages, do not stay up for a long period of time, this is why I posted the whole thing

...UPDATE ON STORM SURVEYS...

DUE TO THE EXTENSIVE AREA THAT HAD TO BE SURVEYED AND THE AMOUNT OF INFORMATION THAT HAS TO BE PROCESSED...FINAL TORNADO STATISTICS WILL NOT BE RELEASED UNTIL SOMETIME SATURDAY AFTERNOON.

...HERE IS WHAT WE KNOW THUS FAR...

DANE COUNTY... THE TORNADO IN THE STOUGHTON AREA WAS RATED AN F3. ONLY ONE TORNADO WAS CONFIRMED AT THIS TIME FOR DANE COUNTY.

JEFFERSON COUNTY... FIVE TORNADOES AROUND THE FORT ATKINSON AREA WERE CONFIRMED.

WALWORTH/RACINE COUNTY... NO TORNADOES WERE VERIFIED.

IOWA...SAUK...COLUMBIA...AND MARQUETTE COUNTIES... STORM SURVEYS ARE STILL ON GOING AT THIS TIME.

$$

When you don't take into account the tornadoes that MKX has not surveyed or completed surveys on yet...we are already around 20 tornadoes which is nearing a daily record which was set on May 8 1988 in the Mother's Day Outbreak (total of 24). That same date holds the record for most tornadoes in Iowa in a day and I believe over 57 tornadoes in all occurred. My facts should be pretty straight on that.

...Alex Lamers...
 
Guys, the images and overall the video of the monster arrived also in Italy television!Crazy and huge tornado.
I can't believe that thre's nota videotape on the web...

Anyone got the video?
 
Just totaled it up more thoroughly and based on PNS's so far, this was a 19-tornado day (in Wisconsin only). However, this does not include a definite tornado in Columbia County and a possible/probable one in Sauk Co. Additional tornadoes may be found here and there but for NOW it seems the all time daily record is safe. Nonetheless it was a historic outbreak.

...Alex Lamers...
 
I know this is a lot to ask, but does anyone have SPC Mesoanalysis Maps from the outbreak (like sig tornado potential, supercell potential, etc.)?

Thanks! :D
 
Top 5 Tornado Days in Wisconsin...
1) May 8 1988 - 24 Tornadoes
2) July 3, 1983 - 22 Tornadoes
3) June 8, 1993 - 18 Tornadoes
3) August 18, 2005 - 18 Tornadoes (preliminary)
5) June 23, 2004 - 17 Tornadoes

The 30 year normal /1971-2000/ for tornadoes in Wisconsin is 21 per year. The year of 1980 had the greatest state total with 43 tornadoes.

Are there statistics available online somewhere on the number of tornadoes this year, by state? (Seems to me there are, but I can't remember where.) Wisconsin has had several smaller outbreaks earlier this year, so I would guess that 1) the record for tornadoes in a year in Wisconsin is in jeopardy, if not already broken, and 2) Wisconsin must account for a large proportion of the tornadoes nationwide this year.

BTW, congratulations Scott and Mark on a great catch of the Stoughton tornado, and thanks, Scott, for posting the link to the pics by locals - a lot of nice shots there!

Current tornado count from 8/18 is 28 statewide (17 in the MKX CWA, equal to the statewide count from 6/23/04) http://www.crh.noaa.gov/mkx/document/tor/081805.php

The several cluster outbreaks of weak tornadoes in central Wisconsin in early June totaled about 20-so that would be at least 48 for the year, a new record.

Well now we know that this has broken the one day record.

COMBINED WITH THE 5 CONFIRMED TORNADOES IN THE NWS GREEN BAY COUNTY
WARNING AREA...AND THE NWS LA CROSSE OFFICE REPORT OF 6 CONFIRMED
TORNADOES IN THE WISCONSIN PORTION OF THEIR COUNTY WARNING AREA...
THIS GIVES A TOTAL OF 28 CONFIRMED TORNADOES ON AUGUST 18TH IN
WISCONSIN.

THIS NUMBER SETS A NEW RECORD FOR THE MOST TORNADOES REPORTED IN ONE
DAY IN THE STATE. THE PREVIOUS RECORD WAS 24 TORNADOES SET ON MAY 8
1988.

Seeing the radar images those tornadic supercells don't seem so much strong from the point of view of reflectivity...It's true that this is not a sign of the strenght of the mesocyclone rotation but I did think to see something like a strong hook echo...I wann say that is pretty uncommon to observe a strong tornadic supercell with a similar hook echo. Besides I don't see a evident isolation of the supercells, typical of the main outbreak supercells.

It could be interesting to see the sounding of those zones but I cant' find it. Maybe it could be a strong minisupercell; Andy, did you observe the elevation of that supercell?
 
It was a pretty classic looking supercell in several stages (including near Viola and Stoughton) but frequently the torando became rain wrapped in other areas of S WI, leading to the appearance of poor overall structure. I can say from watching it from left to right across the state that it looked like your classic cyclic supercell from the Plains. There were hook echoes several times but you need to find those locations and also it is helpful to watch the event in its entirety so it is easier to pick out. There was one over Stoughton and one over Viola for sure (Brett Adair posted the smoothed image over Viola on another thread). Based on mean storm track calculations it deviated an average of about 45 degrees right of the mean storm motion. The g2g was nearly always strong across the entire state although it did get muddled in places.

This was an incredible outbreak, especially for a Slight Risk day -- it didn't look too impressive at the start and the instability certaintly wasn't high or extreme (with rain in the morning and clouds too).

Does anybody have GRLevel3 radar images from the Stoughton/Ft. Atkinson supercell?

Also, I'm still looking for SPC Mesoanalysis Maps from the event. Does anybody know where I could look for them, or does anybody have them, or do I have to wait for a case study by Jon Davies?

Thanks in advance! :D
 
You might try taking a look in the SPC's Severe T'storms Event archive, they save quite a bit of stuff from the day. Not sure if you can find mesoanalysis info though. Worth a shot though.
 
By the way...I bet this is the first year in recorded history we beat out Illinois' tornado count. Perhaps even Oklahoma's too. Certainly we beat Oklahoma's strong tornado count. :p

I find it kind of ironic that I just had the kind of experience that ignited the interest in tornadoes for many of you-yet for me the interest was already there.
 
I put together a composite chart based on archived data from OBS/Wind Profiler/NCEP Fronts/etc:



Kudos to all who got to chase this one, by the time I reliazed the mesoscale setup it was to late.

I first want to say that it was dissapointing to hear that someone died from this tornado. The man was even in his basement. I was leaving town(Madison) at 3 pm. I was on a trip to Ohio when I heard the news about the outbreak in WI. It figures that the day I leave the best opprotunity arrises. I have to believe there was some divine intervention going on there. I could see the supercell from Gary, IN!! I bet that thing was up around 50,000 ft. If you watch the radar loop of the entire event you can see that the same supercell was responsible for most of the tornadoes from Vernon county to Jefferson county. It was an amazing event. I still wished I was there. :cry:
 
I was disappointed I decided not to chase SW Wisconsin on Thursday, even though I watched it unfold all day. The post event "I should have"s were bothering me . But I am gun shy of that part of WI or any part for that matter. Lo and behold I get a call last night from someone I went to high school. He tells me he was in Stoughton on vacation and he filmed the tornado as it passed through and would I like to see it. What the #@!$% are you kidding. Like I always say, the best chases turn out to be the unplanned ones. He has always wanted to see a toenado and this was his first. I'm sure it left an impression.
Here is a link to the video.
