Tornado kills ten in Mississippi

A powerful 1/2 to 1-mile wide tornado cut a path of enormous destruction across the state of Mississippi yesterday, killing at least ten and injuring dozens. It was the deadliest tornado in the U.S. since May 10, 2008, when an EF-4 tornado killed 22 people in Oklahoma and Missouri. The damage I've seen so far from photos of yesterday's tornado appears to be mainly of the EF-3 variety, though we will have to wait for the official damage surveys to be sure. The supercell thunderstorm that spawned the tornado or family of tornadoes maintained a continuous circulation from the time the tornado first touched down in Louisiana near the Mississippi border until the tornado reached the Alabama border. This is an extremely rare occurrence. If the 188-mile path of destruction across Mississippi was from a single tornado, it would rank as one of the longest tracks by a single tornado on record. The record of 219 miles is held by the deadliest tornado of all time, the great Tri-State Tornado of 1925 (though there is some dispute over whether this was one tornado or a family of tornadoes.) Our severe weather expert Dr. Rob Carver has a more complete analysis and imagery of yesterday's tornadoes.


Figure 1. Doppler radar storm-relative velocity of the mile-wide tornado that affected Yazoo City, Mississippi On April 24, 2010. This is an unusually wide and strong circulation for a supercell thunderstorm.

More severe weather expected today along the East Coast
The Storm Prediction Center (SPC) outlined a "Slight Risk" region of concern for severe weather today along the East Coast, from Maryland to Northern Florida. Yesterday, SPC had Mississippi underneath the first "High Risk" area of severe weather concern for the year. As usual, you can follow today's severe weather outbreak with our interactive tornado page and our severe weather page..


Figure 2. Severe weather reports for Saturday. Note the long line of red tornado reports extending across the state of Mississippi. These reports originated from a single supercell thunderstorm that spawned one or more tornadoes that carved out a 188-mile lone path of destruction across the state.

All this talk of met schools and no one mentions A&M? Been running at least a medium sized met program, relative to others, since 1965.
I can see I'll need to peek in more often to keep things honest. (Really, though, not one where there is a heavy tropical lean.)

And how the heck did no one mention Wisconsin? Or Washington? Those two are among the best, if not holding the title of the 2
best, met schools. (apologies if I just missed them)

I was predominately focusing on tropical weather schools, but yes agree. What are your opinions on Penn State? If you've read what Ive heard, does that seem accurate?

Yes, but as I said they kept running the trams and allowed outdoor swimming as the storm was starting to affect them.
That is irresponsible to say the least. But if there is ever a law suit, they can afford the best legal defense money can buy. So they might not be too worried about it.

Yes I concur, when Charley came in the "closed the park" but in the hotel areas they allowed people to swim in the pool during the cane, outrageous. During TS Fay (Which was borderline hurricane) they did parades in 60 mph wind and torrential downpours. Hurricane Katrina saw no closure what so ever, Jeanne did not faze them either. Wow

Did you guys know that Disney stays open for most hurricanes? That in my opinion is just pure negligence, putting peoples lives in danger is not a good thing. And with a upcoming active Florida season, I worry.

I think the putative lows that some models are spinning up are interesting, but let's face it. It's way too early. I don't pay attention to models developing tropical systems in the Atlantic basin until after May 15.

Perhaps we will indeed get a tropical system for real like some models are spinning up. It's possible, of course.

But I'll be VERY surprised.


It's not so unlikely for the Pacific, at the very least.

The whole pattern favors the East Pacific right now. The position of the upper high is more conducive to development in the EPAC rather than the Caribbean, and the reason this all started was because of the Kelvin Wave and MJO upward-motion pulse coming across the Pacific at the same time. The MJO will affect the Caribbean, but the Kelvin Wave will not, and it is the Kelvin Wave that is causing the convergence right now over the east Pacific. Remember Friday night? There was nothing out there, and then the next morning out of nowhere there was deep convection SW of Panama, because the Kelvin Wave arrived overnight. This convergence will only occur over the Pacific, and the only bleeding into the Caribbean will be within about 100 miles of Panama's north shore, and that's it.

The only way I see to get Caribbean mischief is for an organized tropical low to get going in the Pacific, and then get pulled northward by the southerly flow coming in 3-4 days, similar to Arthur in 2008. Like I've said before, most May mischief in the Caribbean has to come, at least in part, from the eastern Pacific. It's hard for the Caribbean to do it alone, especially in the early half of the month.

When were this early in the year there are not enough storms to indicate a pattern of likely formation spots so it is possible for the Central American blob to develop in the Gulf, I highly doubt it though. I expect something in May though.

Could you tell me when the water temperature has been so hot the last time this early in the year and could you also check the wind shear

Arlene 1981. It has happened before. But this is the only one I could find in recent years that happened in early May:



And I doubt anything will come of what the models are spinning up now.

I am from the cayo area were we are used to flash floods but up in the corozal area you usually need a major rain event to get it flooded whitsh does not happen to often but expect it to be very humid at that time of the year

Taking a direct hit from Frances and Jeanne in 04 is what makes me lurk on this blog daily. It was a life changing event that took out my job and the place I lived on North Hutchinson Island in Fort Pierce. Nothing like seeing an island look like a winter up north with out a leaf on a tree in the middle of summer. Thanks for everybodys great info on this blog and lets hope we don't get the storm tracks we did in 2004.

Well, 102 hours does seem realistic, as in it seems possible it will happen. There has been a lot of activity in the EPAC, and you have the MJO wave coming through. I'll give this a 50% chance of becoming an invest, based 100% on the GFS.

Seems reasonable.

It's only not as progressive today because it goes inland sooner then on the previous runs

It definately has. Keep in mind though that this is still 5 days out, and more than likely there's some margin of error.
