Severe weather is expected again today in storm-torn Joplin, Missouri, as rescuers sift through the rubble of their town that was devastated by the deadliest U.S. tornado since at least 1947. A violent high-end EF-4 tornado with winds of 190 – 198 mph carved a 7-mile long, ¾ to one mile-wide path of near-total destruction through Joplin beginning at 5:41pm CDT Sunday evening. In nine terrifying minutes, the tornado killed at least 116 people, injured 500 more, and obliterated huge sections of the town. Damage from the tornado is so severe that pavement was ripped from the ground, and the level of damage is so extreme that this is likely to surpass last month's Tuscaloosa-Birmingham tornado as the costliest tornado of all-time.

The Joplin tornado's place in history
According to our weather historian, Christopher C. Burt in his post, The World's Deadliest Tornadoes, the death toll of 116 from the Joplin tornado ranks as the deadliest U.S. tornado since at least 1947, when a violent F-5 tornado hit Woodward, Oklahoma, killing 181. However, it is now thought that the Woodward tornado was actually one of a series of tornadoes, and the tornado that hit Woodward killed 107 people. If that is true, we have to back all the way to 1936 to find the last U.S. tornado that killed more people than 2011's Joplin tornado. In 1936, violent tornadoes a day apart hit Tupelo Mississippi (216 killed), and Gainesville, Georgia (203 killed.) NOAA's Storm Prediction Center (SPC) rates this year's Joplin tornado as the 9th deadliest U.S. tornado of all-time.
This year's tornado death toll now stands at 482, making it the deadliest year for tornadoes in the U.S. since 1953, when 519 people died. That year, three heavily populated cities received direct hits by violent tornadoes. Waco, Texas (114 killed), Flint, Michigan (115 killed), and Worcester, Massachusetts (89 – 94 killed) all were hit by violent F-4 or F-5 tornadoes. A similar bad tornado year occurred in 1936, when violent tornadoes hit Tupelo Mississippi (216 killed), and Gainesville, Georgia (203 killed.)
Video 1. The last year with more tornado deaths than 2011 was 1953, when three great tornadoes killed more than 90 people each. This old newsreel video shows destruction from the first of these deadly 1953 tornadoes, the May 11, 1953 F-5 tornado that hit downtown Waco Texas, killing 114 people. The wunderground youtube channel has almost 300 old newsreel videos of historically significant weather events.
What's going on?
It's been an incredibly dangerous and deadly year for tornadoes. On April 14 - 16, we had the largest tornado outbreak in world history, with 162 tornadoes hitting the Southeast U.S. That record lasted just two weeks, when the unbelievable April 25 – 28 Super Outbreak hit. Unofficially, that outbreak had 327 tornadoes, more than double the previous record. The legendary April 3 – 4 1974 Super Outbreak has now fallen to third place, with 148 tornadoes. Damage from the April 25 – 28, 2011 outbreak was estimated to be as high as $5 billion, making it the most expensive tornado outbreak in history; the Tuscaloosa-Birmingham tornado of April 27 may end up being the most expensive tornado of all-time—until the damage from Sunday's Joplin tornado is tabulated. Officially, 875 tornadoes hit the U.S. In April 2011, making it the busiest tornado month in history. The previous record was 542 tornadoes, set in May 2003. The previous April tornado record was 267, set in 1974, and April has averaged just 161 tornadoes over the past decade.
So what's going on? Why are there so many tornadoes, and so many people getting killed? Well, the high death toll this year is partly just bad luck. Violent EF-4 and EF-5 tornadoes usually miss heavily populated areas, and we've had the misfortune of having two such tornadoes track over cities with more than 50,000 people (the Joplin tornado, and the Tuscaloosa-Birmingham EF-4 tornado in Alabama, which killed 61 people on April 27.) This sort of bad luck occurred in both 1953, when F-5 tornadoes hit Flint, Worcester, and Waco, and in 1936, when F-5s hit Tupelo and Gainesville. However, this year's death toll is more remarkable than the 1953 or 1936 death tolls, since in 2011 we have Doppler radar and a modern tornado warning system that is very good at providing an average of twelve minutes of warning time. The warning time for the Joplin tornado was 24 minutes. The first tornado warning wasn't issued until 1948, and virtually all tornadoes from the 1950s and earlier hit with no warning. On average, tornado deaths in the United States decreased from 8 per 1 million people in 1925 to 0.12 per 1 million people in 2000. Had this year's tornadoes occurred 50 years ago, I expect the death toll would have exceeded three thousand.

Tornadoes require two main ingredients for formation—instability and wind shear. Instability is at a maximum when there is record warm air with plenty of moisture at low levels, and cold dry air aloft. April 2011 sea surface temperature in the Gulf of Mexico were at their third highest levels of the past 100 years, so there was plenty of warm, moist air available to create high instability, whenever approaching storm systems pulled the Gulf air northwards into Tornado Alley, and brought cold, dry air south from Canada. The La Niña event in the Eastern Pacific, in part, caused this spring's jet stream to have very strong winds that changed speed and direction with height. This sort of shearing force (wind shear) was ideal for putting a twist on thunderstorm updrafts, allowing more numerous and more intense tornadoes than usual to occur. Was this year's heightened wind shear and instability the result of climate change? We don't know. Over the past 30 years, there have not been any noticeable trends wind shear and instability over the Lower Mississippi Valley, according to the NOAA Climate Scene Investigations team. Furthermore, there have been no upward trend in the number of violent EF-4 and EF-5 tornadoes over the past 60 years, or in the number of EF-3 and stronger tornadoes (Figure 3.) However, this year's remarkable violent tornado activity—17 such tornadoes, with tornado season a little more than half over—brings our two-year total for the decade of 2010 – 2019 to 30. At this rate, we'll have more than 150 violent tornadoes by decade's end, beating the record of 108 set in the 1950s. In summary, this year's incredibly violent tornado season is not part of a trend. It is either a fluke, the start of a new trend, or an early warning symptom that the climate is growing unstable and is transitioning to a new, higher energy state with the potential to create unprecedented weather and climate events. All are reasonable explanations, but we don't have a long enough history of good tornado data to judge which is most likely to be correct.
More severe weather today
Yesterday, survivors of the tornado endured a 12-hour period with two severe thunderstorm warnings, a record 1.83” of rain, hail, and lightning that struck two police officers. NOAA's Storm Prediction Center (SPC) recorded 11 preliminary reports of tornadoes yesterday, along with 315 reports of damaging winds and 182 reports of hail up to 3.5” in diameter. The severe weather threat is much higher today, and SPC has placed a large section of eastern Kansas and eastern Oklahoma in their "High Risk" region for severe weather potential, and warn of the potential for long-lived strong tornadoes. This is their third "High Risk" forecast for the year, and the first since the terrible April 27, 2011 tornado outbreak. That day was the busiest tornado day in world history, with 198 tornadoes occurring in a 24-hour period. Over 300 people died. The other "High Risk" forecast by SPC came during the final day of the April 14 – 16 outbreak over the Southeast U.S. Fifty-two tornadoes hit that day, and 26 people died in North Carolina and Virginia. The severe weather threat will continue into Wednesday, when additional tornadoes are likely along a swath from Arkansas to Indiana.

wall cloud with scud clouds rising up into it that looked like a funnel but were actually not ratating with the wall cloud.
This is a shot looking west toward Topeka Kansas, about 5 miles away, as the wall cloud came closer to my position.
Rotating wall cloud coming through Perry Kansas. That speck towards the top is a helicopter.
Very active tornado day 5/22 was. About the same time as Joplin, MO was getting hit, we had this one come right over the Grand Lake RV park and put down some EF-3 damage on the other side of the hay field you see.

They should have evacuated sooner and kept going.
We were only talking about it as it seems that some of the media folks are carrying on that tune of high SSTs when it no longer appears to be valid.
The general impression that SST changes very little day to day is largely accurate, but most folks do not seem to appreciate what a week, or more, of moderate winds will do to SSTs.
It does seem to be trying to start right on cue. Best I could tell from following the EURO it looked to be headed for Mexico sort of like last year.
I agree with this. I have a 75 mile one way commute, I do for the most part listen to local radio on my commute unless listening to ipod or book on tape, but I also have a smartphone with two sources for local alerts as well as alerts in predetermined locations (i.e. work and home). When at home and there is incliment weather, I will tune to local news or weather channel, both of which provide alerts and usually have a few radar sources up to keep an eye on things, ipad, smartphone, computer and TV provide plenty of coverage to know when something is close. Bad part is we don't have a basement here so close to the Chesapeake Bay. About a month ago two tornados crossed my commute route, luckily I wasn't commuting that day or was already home, but the scar remains where all the trees were ripped up. I watched several tornado producing cells on radar and they went around us. I don't care for what's on TV there days anyway with all these lame "reality" shows and "talent contests". I also have a marine VHF handheld radio in the house that has the NOAA alerts.
higher sst's can have a big difference even better with a strong rtn flow to feed systems coupled with daytime heating well picture is not hard to see and it should be a good picture today
Latest ECMWF does have a low crossing Florida @ 168 hours.....you're correct....looks to strengthen and then get pushed west and SW toward the BOC....

Read this earlier: on a deaths-per-capita basis, Joplin's 117 dead would be roughly equivalent to New York City losing more than 19,000 residents in a single disaster.
this just chills me...but...we have a guy there now who told me that they are hearing a fair number of cries for help from within the rubble....that was from early this morning....not sure of the current status...
That high pressure does seem to be our savior sometimes. And sometimes the opposite. If there are parallels between last season and this I hope after an early gulf start we'll get the favorable steering again.
Sure hope this is the end of the terrible tornados...

Or even a small NWS alert radio that can be plugged in to DC power.
My new vehicle came with SIRIUS, and had one channel devoted 24/7 to U.S. weather conditions.
They dropped that channel, but kept one for Canadian weather. Really helpful in Biloxi, MS.
One third of a town of 50,000 people was wrecked. A three quarter mile wide, six mile long trail of destruction. They can't have recovered all the bodies in that destruction in such a short space of time. It may turn out to be a lot worse than is currently realised.

American Red Cross helps prepare residents for hurricane season
David Ball The Orange Leader
ORANGE — June 1 is just around the corner— the beginning of the Atlantic hurricane season.
The Orange County Chapter of the American Red Cross staff and volunteers were out in force on Monday at Ace Hardware — Childs’ Building Supplies in Orange, Walmart in Vidor and Walmart in Bridge City to help prepare residents by giving out preparedness brochures and items need in their disaster supplies kit. They also highlighted some specialty items such as the R150 self-powered hand crank radio, Water Bob and weather radio.
Donna Ferchak, director of emergency services, said forecasters are predicting multiple named storms this season, so now is the time to get prepared.
So many Weirdo's.
So little time....
Situation Update No. 13
On 23.05.2011 at 03:34 GMT+2
More than 2,000 personnel from across the country have enlisted to battle the 44 wildfires burning across central and northern Alberta's tinder-like landscape. As of Sunday evening, eight of those still raged out of control, including the Slave Lake, Alta., inferno that has consumed 4,559 hectares, decimated nearly half the town and left hundreds homeless in recent days. Suppression operations across the province have spread local resources thin, prompting the province to import some 500 firefighters from British Columbia and Ontario to help battle the blazes. The province has also deployed approximately 140 helicopters, 32 air tankers and scores of heavy ground-based equipment, and are warning northern Alberta residents to stay indoors to avoid health risks associated with the deteriorating air quality. A fire ban, which has been upgraded to include fireworks, is still in effect on all provincial land, government officials said Sunday. Fire has scorched more than 300,000 hectares - an area more than four times the size of Calgary - since the beginning of April. Meanwhile, officials are quashing speculation that a firebreak may have helped save Slave Lake from the monstrous blaze. "Many communities do still cut down trees to make firebreaks, however in this case, there was a firebreak in place," said Duncan MacDonnell with Sustainable Resources. "The highway is considered a firebreak." MacDonnell said the trees across the highway are the same distance from the town as they would have been had a firebreak been in its position instead.
He chalks the marked speed and power of the wildfire up to extreme weather conditions. "This was a special fire and it was fuelled by unfavourable weather conditions," he said. Officials say it will be quite some time before they can begin to investigate the details of the blaze. "At this point, we're more concerned with putting this fire all the way out than we are with studying it," he said.
Some of the wildfires still burning across Alberta:
- 23 km south of Loon Lake, 84,700 hectares (out of control)
- 15 km southeast of Gift Lake, 2,238 hectares (held)
- 7.5 km northeast of Red Earth Creek, 19,747 hectares (out of control)
- North of Fort McKay, 8,900 hectares (out of control)
- 21 km north of Fort McMurray, 100 hectares (held)
- 27 km south of Kinuso, 5,797 hectares (held)
- 7 km north of Janvier, 847 hectares (held)
- Richardson Backcountry, 148,000 hectares (out of control)

When I had it, I didn't find the US weather station that useful, really, but at least it was something.
For those concerned, there are car radios that will pick up the NOAA signal - I believe this is sold by Cruchfield for about $120:
Pyle Marine CD AM/FM Radio, NOAA Weather, Detach Face, Wired Remote.
OK!
First thing in the morning..

Hey, we could ban refrigeration in the name of carbon emissions (much, much worse than any TV), millions more could die of food-borne illnesses, and everything would be better.

Hey Atmo, I was somewhat second-guessing myself as well, lol, why I mentioned, see if could reach consensus view...
#160,
Hiya MS Wx,
Guess, as Dr Jeff mentioned, La Nina influence, although sure other climate teleconnections involved... We've certainly had the classic atmospheric signal of persistent La Nina drought over the southern tier for months! Our YTD rainfall here? Thru May 23: 7.54" / 15.63" deficit...
The absurd irony - Watching Atchafalaya floodwater levels rise steadily up to record levels close by to potentially threaten, while the ground is totally parched - extreme drought surrounded by record river flooding! One NE Terrebonne upper bayou stretch (disconnected from floodwater sources) is bone dry with huge cracks 2" across, over a foot deep... Just incredible dryness for location that averages over 63" a year and scary to ponder how the atmosphere will try to balance out in time... Been warm, but have not had record warmth here right on the Gulf - might reach it today, but still have not hit or exceeded the 90F mark officially yet at either KHUM or HUML1 stations.
