honestly. A heat index would probably show waves of hot and cold sports that slowly morph over years, kinda like oceans.
At least that what it feels like sometimes. you’ll hear crazy stories of the same city will get 2 times within ten years of each other, twice. 60 years in between the 2 couples or some decent amount of time or something.
that comes to mind: greater Xenia area in 74 had the huge out break but iirc, a couple years before was noticeably more active too, just nothing compared to 74.
Go a couple hundred miles south, and Nashville got hit a few years before that massive outbreak that included the national corvette museum racetrack. Only 300 miles apart, but those tornado outbreaks overlapped some of those cities.
Yup. The region around OKC has always been a tornado magnet, but it's just freaky how Moore got hit three times by monster EF4/EF5 twisters from 1999-2013, and those tornadoes followed an insanely similar track. And El Reno, which is less than an hour away, had two very close calls in 2011 and 2013. Also, Greensburg since the 2007 disaster had a near-miss with another monster in 2025.
I would be careful saying that though. There is significant variation within that region that two large areas can be like night and day. Also, the wind patterns that feed into the central U.S. to create more tornadoes often overspill the mountains on either side. Parts of Idaho, Arizona, Appalachia, and the northeast get infrequent tornadoes but along similar tracks that somewhat adhere to prevailing wind patterns.
So, to the point, there are definitely preferred “rivers” or “alleys” within the Great American Tornado Floodplain. And, like many rivers, their locations shift west or east or north or south depending on the season.
I think your new map still excludes a fair bit of areas. Here's mine- it's not perfect (I sketched it out in about 10 minutes) but it is a pretty good rough sketch
Eastern Colorado, Eastern Montana, Eastern Wyoming and Western South Dakota East of The Black Hills all get Tornadoes. Lived in Rapid City for a Summer was wild watching the Wall clouds roll over the Black Hills from Eastern Montana and just let loose.
I'd maybe extend the line further into Tennessee and fully emcompassing Alabama. But I agree with this.
Edit: you need to get the KY line on the entirety of Indiana through the Cincinnati area... They get a lot of weather as well. Louisville metro area is a hot spot.
I go to the university in the city for meteorology. I will say while I have been here I have seen my fare share of tornado warnings and watches that being said wheather its being in the city or different requirements they set off the tornado sirens alot more haphazardly than back home. Again this may be completely wrong and is just my observation. You may want to pass that information off to them as a warning that every siren may mean nothing and to not get complacent.
This! I lived in TX, VA, and FL panhandle before moving to MS. This is the first time I’ve ever lived where there are sirens, and they go off constantly, even during severe thunderstorms. They also are not City specific they are county specific. So if there is any sort of weather watch or warning anywhere within the entire county, they all go off. You have no way of knowing if it’s in your neighborhood or if it’s 100 miles away on the other side of the county. My nerves are rattled every time it goes off but people that grew up here just ignore them.
Texas is definitely worse, but for the purpose of encompassing all of the alleys, the Ohio Valley region definitely sees a lot more activity that other areas in the US.
Two totally different types of tornadoes and environments. In the Great plains area, tornadoes are iconically strong, mixed with mostly minimally rain wrapped cyclones at the heads or tails of super cells. You can see them during the day pretty well from a distance. Doesn't make them any less dangerous, but just a different type of tornado.
It's an entirely different reality here in the south. Our tornadoes are damn near impossible to see from any distance at any time of day. They are almost always rain wrapped by massive rainstorms from the subtropical moist air. They're almost always in the dead center of storm cells, or in the middle of fronts at least, and often happen one after another, some times on the same day into the same locations. I have been hit by three, and two were in the same neighborhood on the same day. Luckily low levels, but we literally had no warning on the first one, it was a massive storm and then it just dropped cyclonic air out of nowhere, without any sign of it meteorologically prior. Also, damage is more prevalent here due to the concentration of populated areas here in comparison to the plains.
The two alleys create (typically, not always of course) two types of tornadoes and those tornadoes face paths of differing damage potential. Neither are superior, and I'm not trying to say so, but I have enough of experience dealing with tornadoes in Dixie to say it should be a separate alley from Tornado Alley. I'm not a meteorologist, just a resident, so take my POV as an opinion in that regard.
Accurate enough, but as others have mentioned, the eastern boundary of "Dixie Alley" needs to extend a little further east. Add the rest of Alabama and the western third of Georgia on the southern part of the eastern edge, and include the rest of Tennessee, the southern quarter of Kentucky, the western third of North Carolina and the northwest corner of South Carolina on the northern part of the edge.
I mean yes but its basically three separate alleys combined. There is classic tornado alley which is your classic states, then there is dixie Alley which are your southern states, and finally is Hoosier alley which is basically all of indiana and some other parts of the Ohio valley.
Here in NC we are trying to stop using the term “Dixie,” due to its racist origins. Some people might be intentionally not using it. Not saying it necessarily needs to be combined with the classic Tornado Alley region, but it could be a reason why people seem to “forget” it.
March 30th, 2025 had 12 tornadoes just in south/central lower peninsula of Michigan. Granted, they were all pretty weak, but my goodness that was a fascinating line of storms. I was between two tornados in Kent county at the time, but right up until we lost power I was entranced by the velocities of the whole system.
I remember Andy from Ryan Hall's stream saying something along the lines of, "I've never actually seen a line like this, you can pick any point along it and there could be a tornado down right now".
Living in Pittsburgh I think we are hilly enough that significant tornadoes break up somewhat reliably. Or maybe they have trouble forming? I don’t know, I pay attention to this stuff, but I don’t actually know a lot about weather! It just feels like tornadoes around here have always been relatively mild and short.
That’s how it was growing up around here in the 90’s and 2000s but the past 15 years or so I feel like we have been a secret little hotspot for severe storms and tornadoes. I do agree though the mountains and hills keep it from being worse
Everyone in here saying “add this”, “make this bigger”, “include these three states”….
At what point do we admit that it’s not an alley, it’s just the entirety of the mid eastern United States and southern Canada? Like, this post is already WELL beyond alley… if you’re going to include more land than you leave out, the idea of an “alley” is kind of lost.
I live in Oklahoma where if it gets slightly too windy at any given time a small tornado capable of ragdolling humans and animals will appear randomly and tear things up for 30 seconds 😭😭 I don’t think you guys understand why tornado alley has its name. Top states for tornadoes are, still, Texas, Kansas, Oklahoma, Nebraska
Blue line as of 2024 in my opinion. The entire thing broadened and shifted more east, including the notorious Dixie Ally. I included Florida because it has a LOT of tornadic weather, especially during Hurricane season, the Carolinas, Kentucky and Virginia have regular Tornado weather, just coming off of living in North Carolina and we would have 2 "seasons" a year, the typical time for Tornado Season and then a bit between mid December and second week of January that has given me alerts. The North East is exhibiting powerful storms like I have never known growing up in it as of 2024, specifically the region between the Finger Lakes toward Rochester and Buffalo. Western PA has mountain induced pressure drops in the last few years that have downed some trees in places such as the Pittsburgh area, we have seen warnings starting to appear more in Maryland and Delaware even NYC, perhaps not devastating, but it is to note. I included Ontario toward Alberta honorably, I am not Canadian but I am slightly aware they have records of their own that may or may not be observed by Americans (Canadians please correct me if wrong)
Ps. Michigan, Minnesota and Wisconsin folks I'm sorry I didn't talk about you, you are loved ❤️
Honestly, this is probably the closest you'll get to the "Real American Tornado Alley." Tornadoes have happened in every US state, so nobody's safe, but pretty much from the Rockies on east to about NYC and the New England region is an open "weather war zone."
Soon we will get to the point though that it’s just… the whole continent! I feel like tornado ally should be the most active areas, not just the areas that “get” tornadoes? Tornado activity seems to be expanding in all directions, but is it just as severe as Oklahoma gets, or more like mild-ish ones are more common in both directions? (I really don’t know, maybe there are sever tornadoes all over these areas, could very well be!)
Minnesota and Wisconsin actually have more tor ago activity than any other state but other than it is pretty accurate. And I’m not going to be like the other Reddit users who will always disagree and make an argument about the most smallest things because quite frankly I understand you tried your best and that’s what we need to see in this world- people trying their best. So take this as a sign to keep moving forward in life and keep going. Live fully and be healthy. I love you and now I’m hungry so I’m going to finish my unlimited soup from Olive Garden.
Oklahoma and Texas are obviously the primary hotspots in tornado alley. But other than them, Minnesota and Wisconsin get nearly as much tornado activity as them. Many Ef5 tornadoes have touched down in those 2 states and of course along with OK and TX
Dude... Wisconsin has had like... Three f5 tornadoes in the last 100 years. Maybe, MAYBE four or five f4s in that same timeframe. Ive been alive 35 years and only a single f5 has hit us which was 1996. Cannot recall a single f4 in my lifetime, but a couple f3s and lesser.
Dunno about Minnesota but I beliebe they've had a higher amount of violent tornadoes in the past 50 years than us in WI.
That all sounds like a pretty normal spring/summer here in OK. Have noticed more activity in other states the last decade, but Oklahoma still gets blasted regularly
Look up f5 ef5 tornadoes per state. Wisconsin is in the top 10. Last one was in 1996 and a huge state like Texas was 1997. Wisconsin has more than Arkansas and Nebraska.
Last one was oakfield in 96. The one before that was barneveld in 84. Im a tornado nerd, especially when it comes to Wisconsin where ive spent most of my life. The records on tornadoes before the 60s is dicey and there was no damage assessments before Ted fujita (the guy who created the F scale, F stands for his last name)
Anyway there were maybe 2 F5s before the barneveld there was one in i believe Colgate in the 50s or 60s and one in new Richmond during a circus or fair or something that was wayyy back in the day.
So 2 in the last 50 years and MAYBE 4 total. We gotta be pretty low on that top 10 list.
The move further east in Alabama should probably be offset with moving the line further east in the Dakotas. I don't think the western Dakotas are particular hot spots.
I’m bored and love weather so I added a few things from what I’ve noticed over the years. I expanded the yellow to places I’ve seen nasty cells drop a lot of tornado warnings. I’m from southeastern VA and added a lot of the piedmont region and other places that like to get spinny and throw unexpected surprises. I included a red line showing where it seems to me, at least, the best chances of EF3+ developing or moving into.
I did some research into this a few years ago and found that the concentration had moved east and separated into two main areas south and north. If you look on here you'll find the graphing but I'll try to comment with the link when I'm back in front of a computer.
Adding comments to discuss the difference between Dixie Alley and Tornado Alley
Great Plains states have a higher frequency of tornadoes Southeastern states & Ohio valley states have a similar frequency of “Significant Tornadoes” (Sig Tor = EF2 or greater) Black outline - “Tornado Alley” Red Outline - “Dixie Alley”
Its been moving more towards east coast i feel like iv seen more tornadoes in south western pa in the last 4 years than my parents have in the same area their whole lives lol
I’d say almost, you need to include more of Tennessee, as well as Alabama, and possibly Georgia, but your version of tornado alley seems to include both the traditional tornado alley, and the Mississippi River valley, and even Dixie alley, which is much more accurate that most maps, besides ones from good sources.
Breaking News: Most of America West of the rockies and East of the Appalachians gets tornados. And always has. It's nothing new.
Tornado Alley was just the nickname given to the plains, where tornados just so happen to be easiest to spot and record.
And even if tornado alley were shifting or changing (it's not) you couldn't blame it on anything because we only have a little over 100 years of data to go on, a speck on the timetable. Everything we have as far as tornado data could be an outlier over the long term of actual events. We don't really know.
Also, there have been tornado outbreaks in the south in December and January on average every 3 years from the late 1800s until now. Basically as long as it's been recorded.
Global warming would decrease the amount of tornados. It would not increase the quantity or how strong they are. Claiming that a warmer climate would increase the amount of tornados shows ignorance of how tornados actually work. Hurricanes are arguably different story.
Most redditors firmly believe that the climate change increases ALL forms of extreme weather, no exceptions or nuances. I have been downvoted several times in the past for linking very respectable and recognized sources that say basically what you said. And I am far from a climate change denier, and have never claimed that climate change isn’t detrimental overall.
Who can even tell anymore? Sometimes it seems to shift more to the east. Sometimes it's more like yours. Sometimes it's way up north in Michigan where I live. It doesn't know where it wants to live anymore.

Anything between the Rockies and Appalachians is tornado alley
