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.

If the parameters setup we should have a lot of long-track type storms forming.

Oh boy, and we all know what that means...glued to the computer.

There was only One in August 92...the first of that year.

It took Lives in 2 States.

Sadly with the way things are shaping up we might have another one follow in Andrew's foot steps.

Looks like 2004 looks like a better comparison track-wise due to the current forecasted placement of the Bermuda/Azores high.


I thought so too

Quoting Drakoen:
I think the tracks this year will be more like 2004 and 1998 but that is only speculation. Notice how we have two predominant tracks: Some storms that recurve out into the subtropical Atlantic and then storms that impact the U.S. Gulf coast and Eastern Seaboard.

Wouldn't be surprised to see something nasty in Mims, Scotsmoor area tonight (South Volusia/northern Brevard). They are usually the ones who get hit when a strong front blows through. Wonder if it's because it's so low and flat through there. The thousands of acres in the Merritt Island National Refuge love the rain!

National Park Overview:
Merritt Island National Wildlife Refuge (MINWR) headquarters is located five miles east of U.S. 1 in Titusville, Florida. The Refuge, which is an overlay of the John F. Kennedy Space Center, was established in August 1963 to provide a buffer zone for the National Aeronautics and Space Administration (NASA) in the quest for space exploration. Approximately one half the Refuge's 140,000 acres consist of brackish estuaries and marshes. The remaining lands consist of coastal dunes, scrub oaks, pine forests and flatwoods, and palm and oak hammocks.

The coastal location of MINWR, with its seven distinct habitat types and position between the subtropic and temperate zones contribute to the Refuge's importance as a major wintering area for migratory birds. Over 500 species of wildlife inhabit the Refuge with 16 currently listed as federally threatened or endangered. Several wading bird rookeries, approximately 10 active bald eagle nests, numerous osprey nests, up to 400 manatees and an estimated 2,500 Florida scrub jays can be found on the Refuge.

Steering currents ...trying to ask all the questions now so I can better read this when it gets a bit more crazy ...
Ok let me make it simple. Steering currents are what steer an area of low pressure, tropical storm, hurricane etc...When looking at a graph like the one depicted the tighter the lines are the stronger the currents are. In the graph you saw the currents were pointing to the EPAC, thus chances are it will likely mover southward to the EPAC. For a better explanation ask Drakoen or StormW.

The Destruction in Mississippi was ridiculous - The Models seemed off on this one. Up to a couple days before the event they really didn't show the threat.


Actually, our NWS office was calling for this event nearly a week in advance. They did a great job forecasting this outbreak. I realize you're talking about the models, but according to the forecasters, the GFS and Euro did a nice job advertising this event.

Yes although it probably favors the EPAC, in either basin the SSTs are high enough to form a TC.


Yeah, I'd say the EPAC is more likely.

Quoting KoritheMan:
It appears that the models are correct after all, the GFS in particular, in forecasting tropical cyclogenesis over the EPAC/SW Caribbean. Satellite imagery indicates a large surge of moisture in the extreme eastern Pacific, and shear levels are already starting to drop, faster than expected even.

We might have Agatha or Alex soon.

Looks like some of that moisture from the ITCZ is starting to flow into the Caribbean now, there is a tight "blob" over Colombia and some of the EPAC moisture is heading over Panama and into the Carribean.

Steering currents are rather weak but favor EPAC movement.



Other than that the GFS has been forming for quite some time now an area of low pressure in the Gulf of Mexico.

Storm it will be a bad year for me in 2010. If anything comes ashore here in Miami (which I hope not) I will keep everyone informed with the latest until my computer dies. lol.

Here's the CFS for this upcoming August. Notice how the high is west of the Azores and extends its ridge axis well westward like 2004.

2004 was a bad year for me in Miami, look at all the systems that impacted me.

txjac~ It's one of those things I've always been good at. I did take some related classes in college while pursuing a degree in Physics/met. A long dry spell in hurricanes & the pursuit of other interests led to a change in majors a few times, finish as a top US equestrian competitor..& a BS in Animal, Dairy, Veterinary Science~ Business & Production. Minored in Equine & art. Wouldn't take much for a BS in Physics, BioChem, forestry or something in the atmospheric sciences..School was fun, also did a lot of canoeing there. Was there a while. Being able to schedule around the weather or spot a mess blowing up was really useful when I led people into the wild on horseback for days on end, ran equestrian businesses & racing departments. But yeah guess I've been a little obsessed since standing in the eye of David as a kid. Happily doing what ever I want now, not tied to a job or clients to campaign (except my stallion), so watching the weather entertains my want to watch numbers & trends.

Looks like 2 possible brief EF0 may have touched east of Pinellas..Tampa might have had some wind.

five storms in august that year? geeez, that's one every six days.

Found a National Geographic from August '05. Last one before Katrina. There was a sweet, naive, poignant story in it, about the '04 Season™.

I read it and thought, "oh, if they only knew.."

had a 56 mph gust at home here in central Pinellas county, over inch of rain in a VERY short time, blinding rain, similar to rainfall rates we receive in the wet season, too short lived to add up more then an inch or 2 though, could actually smell salt water in the air!

Should see even more activity overnight with the next shortwave, expecting about 3 inches or so before it clears tomorrow.

I don't know if anybody heard, but the Yazoo City tornado has been rated EF3.

It may have been EF4 or EF5 depending on further surveys.

We're bound to see a lot supercells develop across central Florida this evening. CAPE values are high high, there's a very mist dewpoint, and temps are still in the mid 80s.
