i still think ok is the best area for chasing even thought ks and ne have had more tornados the last 4 years because over the past hundred years hasn't oklahoma been 2nd only to texas in tornados and we know why texas is number one.
 
Those stats are a great example of how different areas will "shine" on the climatology if you take different time periods into account. Of course anyone who's seriously chased since 2000 doesn't need the charts to know Mike's research is 100% accurate. If you researched the period of 1990-1995 I'd imagine there's another Kansas bias there as well. This gives me hope that my home state of Oklahoma will someday return to glory. Until then, I've nicknamed it "The Rhode Island of Tornado Alley."

I like to use tornado days, instead of number of tornadoes.

Big outbreak days, tend to skew the data, and also the way tornadoes are counted these days, is somewhat annoying. I will not go into details, my opinions, when it comes to how people are counting tornadoes.

Mike
 
so mr. geukes do you think nebraska is on a pace for a reocord number of tornado days this year
 
I think Nebraska would often either meet or exceed Kansas's totals annually if the sandhills area were criss-crossed with roads. The sandhills and their non-existant roads cover at least 1/4...and maybe 1/3 of Nebraska's total square miles.
Some of the largest mesos ever seen on radar have happened in that sandhill area. I would bet too, that many F-5's have occurrred there too. Also, this area will tornado right on through July, and even August too.
Just a thought.
 
Oops....in my post above I neglected to thank Mike for taking the time and energy to compile the list in the first place.
BTW.......Mike, is your last name pron. "Goo-kus"? Thanks for the help there too!
 
thanks for taking time for doing the research because i had no clue nebraska was up in the upper echeleons of tornado country, like texas,oklahoma, and kansas.
 
Oh yes, Nebraska is definitely a tornado heavyweight. If I'm not mistaken, their tornado count from 1950 thru 1995 put it at either #4 nationally or #5. I think Neb. is #5, with Florida #4. However, there are an awful lot of weak waterspouts that come ashore in Fla. that do basically no damage other than blow around some lawn chairs, etc. They would be akin to the "dust devils" of the southwest.....vortexes that are derived from rising air currents. rather than spawned by rotating storms. Yet these get counted as a tornado..and pushes up Florida's tornado tally, rather erroneously I believe.
Last May 24th the largest diameter tornado ever recorded in the United States was southwest of Lincoln...a F-4 monster that was offically measured at 2 1/2 miles wide!! The little town was named Hallam, and I went to college directly up the road from there in the mid 70's....and had a lot of frat bros. from Hallam.

Tornado density

I took Mike's tornado numbers and divided them by each state's area, then multiplied by 100 to come up with a tornado density. A circle with a radius of 5.64 sq miles covers 100 square miles. This does interesting things to the rankings:

01 FL 4.95
02 OK 4.18
03 KS 3.27
04 IA 3.24
05 LA 3.14
06 IL 3.09
07 IN 2.97
08 MS 2.88
09 NE 2.82
10 TX 2.65
11 AR 2.49
12 AL 2.42
13 MO 2.17
14 SD 1.90
15 GA 1.88
16 WI 1.81
17 NC 1.74
18 ND 1.55
19 MN 1.55
20 MI 1.49
21 CO 1.48

Of course, tornadoes in Illinois and Indiana often come in squall lines or HP supercells, both of which present their own added dangers while producing less photogenic storms. The tornado season here is also not as strongly defined as it is in Oklahoma. And, our tornadoes seem more likely to strike at night.

I suspect that squalls and/or HP supercells and/or tropical storms figure greatly in the South as well. At times, the archetypical Indiana tornado seems like an F2 on the south edge of a squall line striking at 2 am in the middle of a heavy rainstorm.
 
Im curious as to what Illinois' total tornado days would be for the 2000-2004 time period, as I know Illinois lead the nation by quite a bit in 2003...and was also very near the top in 2004.

Yes, it is interesting how that changes the rankings. But it's important not to forget how much of those square miles are "wasted" due to non-existant roads / populations non-existant. For example, Cherry county Nebraska.....in north central Nebraska....is one of or THE largest county in the lower 48 with the least amount of people. And Cherry county gets hammered with tornadoes....huge ones too! North Platte spots them on Doppler, but no one's out there to provide ground truth.....and there's not much there either to damage / provide damage assessments.
 
Thanks for the speedy info mike, you rock!

Confirms what I suspected...suckers, Illinois leads KS/OK/NE in May tornado days from 2000-2004 :lol: :wink:
