Deadliest U.S. tornado since 1953 rips through Joplin, Missouri, killing 89
The incredibly violent tornado season of 2011 struck another sickening blow last night, when a violent tornado carved a ½ – ¾ mile-wide path of devastation through Joplin, Missouri. At least 89 people died, hundreds were injured, and huge sections of the town virtually obliterated. Damage from the tornado is so severe that pavement was ripped from the ground, which is characteristic of a top-end EF-5 tornado with winds in excess of 200 mph. This was almost certainly a least an EF-4 tornado with winds over 166 mph, 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.

Note the pavement ripped up from the road and piled in front of the cars. Tornadoes powerful enough to rip up pavement are frequently classified as EF-5 with winds in excess of 200 mph.

The huge supercell thunderstorm that spawned the Joplin tornado formed over extreme southeast Kansas yesterday afternoon, along the boundary between warm, moist air flowing northwards from the Gulf of Mexico, and cold, dry air moving south from Canada. NOAA's Storm Prediction Center (SPC) had put the region in its “moderate risk” region for severe weather. As the supercell moved into Southwest Missouri, it spawned the tornado that roared through Joplin at 5:45pm CDT. This storm generated other tornadoes, straight-line wind damage, and flash flooding from torrential rains that exceeded six inches as it moved east southeast across Southwest Missouri. SPC recorded 48 preliminary reports of tornadoes yesterday, bringing the 2-day total for the current outbreak to 70. A tornado also killed one person and injured 22 in Minneapolis Sunday. Separate tornadoes killed one person each in Andice, Texas and Reading, Kansas on Saturday—the first tornado deaths in the U.S. since the April 25 – 28 Super Outbreak.

Deadliest tornado since 1953
Yesterday's Joplin, Missouri tornado is the deadliest single tornado in the U.S. since June 10, 1953, when 94 people died in the Worcester, Massachusetts tornado. The previous deadliest tornado in the past 50 years occurred just last month, when 65 people died in the Tuscaloosa-Birmingham EF-4 tornado in Alabama. This year's tornado death toll now stands at 455, making it the deadliest year for tornadoes in the U.S. since 1953, when 519 people died. The deadliest year was 1925, with 794 deaths. That was the year of the deadliest U.S. tornado of all-time, the great Tri-State tornado, which killed 695 people in Missouri, Illinois, and Indiana.
More severe weather today
NOAA's Storm Prediction Center has placed a large section of the Midwest U.S., including portions of Oklahoma, Kansas, Missouri, Illinois, Ohio, Michigan, and Pennsylvania, in its “moderate risk” region for severe weather today. The threat of tornadoes will not be as great today as yesterday, with today's main threat being large hail and damaging straight-line thunderstorm winds. However, I do expect we will see a dozen or so tornadoes today, and residents of the at-risk area need to keep in mind the deadly history of this storm system. The severe weather threat will continue into Tuesday, when additional tornadoes are likely over Oklahoma, Kansas, and Southwest Missouri. A severe thunderstorm roared through Joplin between 8:30am and 9am CDT this morning, bringing heavy rain, small hail, and wind gusts to 36 mph. Undoubtedly, this storm frayed some nerves, and the city will remain at risk of seeing more severe thunderstorms through Tuesday night.

The most remarkable audio I've ever heard of people surviving a direct hit by a violent tornado was posted to Youtube by someone who took shelter in the walk-in storage refrigerator at a gas station during the Joplin tornado. There isn't much video. We won't see a lot of spectacular videos of the Joplin tornado, since it was wrapped in rain and difficult to see.
Listen to my 12-minute interview on the historic April 2011 tornadoes for EarthSky.org, which aired on NPR earlier this month. I discuss how climate change might impact severe weather and tornadoes.
Our weather historian, Christopher C. Burt, has an excellent post on The World's Deadliest Tornadoes.
My 2008 post, Are tornadoes getting stronger and more frequent? The answer is--we don't know.

Helping out tornado victims
For those who want to lend a helping hand to those impacted by the widespread destruction this spring's severe weather has brought, stop by the Red Cross website, or portlight.org blog. Portlight has been very active bringing aid to the victims of this year's tornadoes.

ok
Current TorCon index at 7 in south-central KS and north-central OK.
If you read the article I posted 253 it seems all the ingredients are coming together for a serious outbreak tomorrow. Lets just pray they stay away from populated areas. Have some potential for some big long track nados

He is right tommorow has all the right stuff for a major outbreak. Right now though a chaser named lance ferguson has a low roatating wall cloud Link down below

These storms are warned North of Memphis
Amazing how it went from a tiny funnel cloud to massive tornado in 30 seconds. :(
Sheri nothing i see currently......but, things can change fast right now!
I wasn't implying he was wrong. Only quoting another source that tomorrow is shaping up to be a PDS.

I thought that might be the case. If only 4 people died in there, that is amazing. Not for them of course but looking at the devastation at that building.
Forecast of thunderstorm potential for the province of Ontario
Issued by Environment Canada at 4:02 PM EDT Monday 23 May 2011
The next statement will be issued at 4.00 AM Tuesday.
------------------------------------------------- --------------------
Forecast of thunderstorm potential.
Tonight..There is a slight to moderate risk of severe thunderstorms
over Southern Ontario this evening with the passage of a strong cold
front and associated upper level jetstream. The moderate risk is
expected to be confined to Southwestern Ontario and east of Lake
Huron. Thunderstorms in the risk area have the potential to produce
brief damaging wind gusts in excess of 100 km/h. There is also a
lesser threat of large hail of 2 to 4 cm and an even smaller risk of
a tornado. Additionally many portions of Eastern and Central Ontario
will experience isolated thunderstorms capable of producing small
hail and brief wind gusts to 70 km/h. Thunderstorms activity is
expected to weaken or move out of all regions of Ontario by shortly
after midnight.
90E 20% Chance Of Formation, I say in it's Lifespan: 20%(Unless Wind Shear Becomes Favorable)
92L 20% Chance Of Formation, I say in it's Lifespan: 50%(An Anticyclone is forming over the system causing wind shear to drop dramtically,30 knots, making it favorable for the surface low, The wind shear is high around 200 miles away all around, but is not seriously directly impacting the system) This is why you're seeing some convection beginning to form near the surface low. It has a long way to go, but with low steering currents for a few days, and low shear, it will be just wobbling around in the sub-tropics all week.
I'll Be Posting A New Blog Later On This Afternoon...

Updated 4:45 p.m. EDT:
President Obama has ordered a full-scale federal response to deadly tornadoes that struck Missouri on Sunday night.
FEMA Administrator Craig Fugate is traveling to Missouri on Monday to begin assessing what might be needed from the federal government.
At least 116 people are dead in the town of Joplin, where homes and hospitals were damaged by storms that ripped through the town Sunday night. Government forecasters said Monday that the Joplin, Mo., tornado is the deadliest U.S. twister on record since 1953
