Here is the record for Chadron, Nebraska. https://www.wunderground.com/history/airport/KCDR/1989/12/21/DailyHistory.html?req_city=&req_state=&req_statename=&reqdb.zip=&reqdb.magic=&reqdb.wmo=
I think it is likely Kansas has had -50F or colder WC's just no records to indicate it. My dad told me he had a temperature of -19F wind winds blowing between 25 and 35 mph in Emporia back in 1983. However no records to confirm it. He had a wind chill of possibly -50F to -52F(-72F to -77F using old formula).
-
On February 5, 1982 at 6:43 am there is an unknown temperature with a wind speed of 16.1 mph. So depending on whether the temp was -22F or -23F it would make the WC -48F or -50F. Most Kansas offices have no good records but Goodland has some really good records. https://www.wunderground.com/history/airport/KGLD/1982/2/5/DailyHistory.html?req_city=&req_state=&req_statename=&reqdb.zip=&reqdb.magic=&reqdb.wmo=

Not sure if this is a record, but Christmas Eve '83 was a b**ch in Ohio, here's KDAY:
12/24/1983 7:00PM -15.0°F -43.2°F -27.9°F 52% 30.45in 4.0mi West 23.0mph I found this for Mansfield, Ohio on January 20, 1985. The temp was -22.0F with a wind speed of 24.2 mph creating a WC value of -53.1F. https://www.wunderground.com/history/airport/KMFD/1985/1/20/DailyHistory.html?req_city=&req_state=&req_statename=&reqdb.zip=&reqdb.magic=&reqdb.wmo=

That was Christmas Eve 1983 in Emporia, Kansas but he was out in a more open area and probably colder than in town. I think on the new WC scale it would be like -50F to -53F. I tend to think it may be somewhere in the low to mid -50s but I could be wrong.
-
What is the coldest wind chill ever recorded in Kansas using the new WC formula?
-
The calm in the middle of the tornado is still astounding to me, maybe there's more to tornados we don't know yet and this one is an example
I have also had wondered that for some time for I have mentioned it before. It seems like one area in parts of a tornado may have winds that are non existent but like maybe a few feet away from that area winds of 200 mph or more. It may explain why some well-built buildings are completely swept away but a pole or some object you would have expected to be destroyed as well remains untouched.

Jamie McMurray, NASCAR driver, returned to Joplin this week w/ the race at Kansas City, his childhood home lost the roof and some of the exterior walls.
I suspect he'll be donating generously to the relief. He also visited his old school, Joplin High.
I gave $20 for the Reading tornado victims to our hospital here in Emporia where I work. I sent $25 through Red Cross to the Joplin but may send a little bit more through Salvation Army around another $25 when I get paid Thursday. I wish I could send a huge donation but I am not exactly rich. God bless them people in Joplin.

Interesting article about the guy that filmed the video of the tornado, Jeff Piotrowski. Also what he did as a first responder on the scene.
"Using an Internet card on his laptop, he was finally able to get a call through to his friend Steve Piltz, head meteorologist and director of the National Weather Service station in Tulsa.
Steve answered.
“We are in a state of emergency, Steve. Joplin needs help. A massive tornado, at least an EF-4, maybe an EF-5 touched down here. Massive damage, massive injuries. Need ambulances. Can Oklahoma send any? Can you send 100 of them?”
Piltz looked at the radar and saw the debris cloud. “Oh my God,” he said. The debris clouds on the radar image were enormous.
“You got it Jeff. I’m on it,” Piltz replied.
Piltz sent the storm chaser report immediately. Within 15 minutes of the call, Task Force I Search and Rescue teams from both Oklahoma and Arkansas were dispatched and on their way to Joplin.
Jeff could breathe again, and stop counting. Help was coming, more was on the way."
I personally met Jeff a few years ago when storm chasing with a few other guys. He is a really nice guy but he is way out there when it comes to chasing tornadoes.

With insane parameters like that is just out of this world. I mean 9000-10000J/Kg, 1000m2/s2, LCL's 200m, 80-90kts, temperatures mid 80s, dews in the low to mid 70s, EHI's of 15, LI's of -12, followed by a powerful cold front or dryline, and addtional other insane parameters. I am afraid that some of our states would not be existing anymore. There would be multiple PDS tornado watches with all probabilities >95%. They would state numerous violent tornadoes, numerous wind gusts in excess of 180 mph, and numerous hail stones to the size of bowling balls/basketballs. You may also have flooding torential rains of one feet/hour. I would thin k something would be out of this world scary.

I saw this the other day. A bank was destroyed and all that was left was the vault.
Saw this story about a UA student who lives in Joplin and was in Tuscaloosa at college and the tornado missed her by about 3 blocks. She drove home to Joplin and 3 weeks later, the tornado here missed her by 3 blocks as well.
http://www.tuscaloos...03/1007?p=1&tc=
There was also a local news story on a man who lived in Racine, MO and lost his wife in the Picher, OK storm when it moved into that area. He moved to Joplin with his daughter and rode out this storm in one of those twister safe tornado shelters. His house was destroyed but the shelter survived.
That is a very impressive picture but also very scary. I wonder if that is EF5 damage.
-
The official estimated max winds in Greensburg and Parkersburg-New Hartford were 205 mph. Where did you get those higher values?
I agree with you-- that 225 mph seems like a more reality-based value for Joplin, simply because the higher value (250 mph) would be a whopping 25% higher than other EF5s-- something which is hard to believe.
P.S. Good point-- that these are simply estimates. Lord knows how accurate they really are. I'm sure there's a wide error range when talking winds this high.
It is just my personal guess on the Greensburg and Parkersburg/New Hartford tornadoes as well as the other EF5's in April. I am far from being expert it is just my personal opinion.
-
I would probably would say the lower value of 225mph would probably seem like the more appropriate value. That one tech building JoMo showed in damage photos was clearly at least EF4(180mph) and probably EF5(200-220mph). These more recent tornadoes such as the one in Hackleburg may have winds around 220mph, as well as the Smithville and Philadelphia tornadoes. The Parkersburg tornado if you used the upper bound on a well-built home that was swept away that would be 220mph. Greensburg had EF5 damage to about six victorian homes that were swept away as well as the brick buildings being crushed into rubble I would estimate around 210-220mph. Like I said winds are winds and its only an estimate in association to the damage produced.
-
On a tangent sorta kinda-- but the path length of the tornado has been extended to 13 miles.
That tornado came out of nowhere from an area I never would have suspected. 13 miles is not extremely long tracked but still the tornado was able to annihilate parts of Joplin and live not as long as I would think. The conditions that day were favorable for strong tornadoes but I never would have suspected a tornado of that magnitude in the area it was at. There was a 10% hatched area for strong tornadoes in Joplin. It also probably wasnt favorable for extremely long-lived tornadoes but the Joplin tornado was very violent and something you would not expect. I have heard of a few times strong tornadoes in lower risk days but like I said this tornado was extremely violent. It seems very real now that a mile-wide EF5 tornado could take a 30-40 mile path through downtown Dallas during the middle of rush hour traffic killing thousands of people. I would hate to think something like this would happen but ever since this tornado in Joplin it seems very possible.
-
The whole thing on the Joplin tornado just blows my mind. I know its not impossible because it has happened in Joplin. How is it that a tornado of this magnitude live for not even 10 minutes, be on the ground for only 7 miles, max out at EF5 over Joplin, and destroy that beautiful city? I mean it is just beyond my comprehension how a tornado could destroy that much of that city and kill over 100 people in such little time. It is just truly scary and unthinkable.
-
Dont mean to get off topic but if a mile-wide EF5 tornado is referred to as a monster then what would you consider a rope EF5 tornado?
-
Birmingham mentions they had the foremost national expert in storm damage assessment to assist their team in determining the strength of the Hackleburg storm. That would have to be Tim Marshall IMHO.
Yes I believe it was Tim. The aerial view of damage was amazing
-
It is hard to imagine a tornado spinning up EF5 damage that quickly, though I am no expert on the subject. These storms were moving 60+mph at times though so were talking about a 2 1/2 minute tornado that created EF5 destruction? Wow if that's the case. Looking at a map it would appear this could have been part of the same long track supercell that devestated Hackleburg and moved towards Huntsville?
It makes me wonder if a rope tornado(<100 yds wide) could move along the ground at 70+mph and still do EF5 damage. Has anything like that ever occured?
-
The death toll has exceeded 300 according to CNN. ~305 fatalities.
-
Here is some comparisons though not quite as widespread as what was in Parkersburg.
http://www.crh.noaa.gov/image/dmx/ParkersburgSvcAssmntfinal.pdf
-
Aerials look like what the Parkersburg tornado did in 2008. It is really hard to tell the difference because this tornado was rated high-end EF4 but the Parkersburg tornado was rated EF5. I also believe the Parkesburg/New Hartford tornado did more ground scouring, tree debarking, and sweeping homes even more clean from their foundations than this tornado.
-
Wow Godspeed to any and all who were affected by this great feat of God. Absoloutly horrific, words cannot express the shear devastation. Amazing the death toll isn't higher. This is making 1974 pale in comparison.
I dont know about that but this will defenitely be in the top 10 deadliest tornado outbreaks of all time. Fatalities and injuries are probably close to the same as in the 1974 Superoutbreak. There will probably more tornadoes confirmed but I dont believe there will be as many violent tornadoes confirmed from this outbreak as in 1974. Hard to compare both because they were beyond devastating.
-
First of likely many violent tornadoes:
This is a very high-end EF4.

I have never heard of NWS rating a tornado an EF4 with winds of 190 mph before. It sounds right to me although by the description of the damage (180-190 mph winds).
-
Certainly looks like an EF4 candidate, with even the interior rooms destroyed. But I will reiterate that it is virtually impossible to say with any certainty whether a tornado was EF5 without inspecting construction of the building.
I might say EF4 based on the damage and also that depends on the construction. If I had to do this survey I might start with EF3-EF4 and if I think any of this damage might qualify as an EF5 I would get several experts opinions before rating it that.
