Deadly tornadoes rip OK, KS, and AR; high tornado risk today; Joplin tornado an EF-5
America's deadliest tornado season since 1953 continued its relentless onslaught of violent tornadoes yesterday. Numerous destructive and deadly tornadoes raked Oklahoma, Texas, Kansas, and Arkansas, killing at least nine people. Yesterday's deadliest tornado hit El Reno and Piedmont, Oklahoma, about 30 miles to the west and northwest of Oklahoma City. Four people died, and one child is missing. Video of the damage from this tornado near the town of Piedmont shot by a news9.com helicopter shows damage characteristic of an EF-4 tornado, with many homes completely demolished and swept off their foundations. This tornado produced a wind gust of 151 mph at an Oklahoma Mesonet station in El Reno, Oklahoma.

Figure 3. Top wind gusts recorded by the Oklahoma Mesonet yesterday showed that over 2/3 of the state received gusts of 40 mph or greater, and ten stations got gusts in excess of 58 mph (the definition of a severe thunderstorm.) A remarkable gust of 151 mph was recorded in El Reno, about 30 miles west of Oklahoma City.

Joplin, Missouri got a scare last night when Doppler radar showed a rotating thunderstorm approaching the city from the southwest. A tornado warning was issued and the sirens sounded, but the storm passed just to the northwest of the city, bringing Joplin only heavy rains, wind gusts to 41 mph, and intense lightning. A tornado warning forced the evacuation of NOAA's Storm Prediction Center (SPC) in Norman Oklahoma late yesterday afternoon, and the center was out of commission for a 50-minute period. However, yesterday's dangerous tornadoes missed the most heavily populated areas of Oklahoma, and SPC was able to resume normal activity after the storms cleared Oklahoma City. The center logged 47 reports of tornadoes yesterday, bringing the preliminary 4-day total of the current outbreak to 153 twisters. With more tornadoes expected today over a wide swath of the country from Arkansas to Ohio, this week's tornado outbreak is likely to rank as one of the top ten tornado outbreaks in history. This year already has the two largest tornado outbreaks in history, the April 25 - 28 outbreak (327 tornadoes) and the April 14 - 16 outbreak (162 tornadoes.)
This year's tornado death toll is in the 495 - 499 range, 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 (90 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.)

This storm had unusually high radar reflectivity (note the pink colors of 70 dbZ echoes), because of large hail in the storm. This thunderstorm produced softball-sized hail (4.5 inch diameter.)

The Joplin tornado an EF-5, and the costliest tornado in history
The Springfield, Missouri office of the National Weather Service announced yesterday that storm surveys of the 7-mile long, 3/4 mile-wide path of damage carved by the Joplin tornado revealed that winds in the violent tornado exceeded 200 mph, making it the 4th EF-5 tornado of the year. The twister roared through Joplin beginning at 5:41pm CDT on Sunday, May 22. In nine terrifying minutes, the tornado killed at least 125 people, injured 750 more, and destroyed 2,000 buildings. NOAA's Storm Prediction Center (SPC) rates this year's Joplin tornado as the 8th deadliest U.S. tornado of all-time, and the deadliest since at least 1947, when a violent F-5 tornado hit Woodward, Oklahoma, killing 181.
Catastrophe risk modeling firm EQECAT said yesterday that insured damages from the Joplin tornado could be between $1 billion and $3 billion dollars. According to NOAA's National Severe Storm Laboratory, the costliest tornado between 1890 - 1999 was the May 3, 1999 Oklahoma City tornado, which did $1 billion in damage (1999 dollars.) There were no tornadoes during the period 2000 - 2010 capable of causing $1 billion in damage; the only two EF-5 tornadoes during that period, the 2007 Greensburg, Kansas tornado and the 2008 Parkersburg, Iowa tornado each did less than $300 million in damage. Thus, with the possible exception of this year's Tuscaloosa-Birmingham tornado of April 27, the Joplin tornado is probably the most damaging tornado of all-time.
Another "High Risk" day for severe weather and violent tornadoes today
The Storm Prediction Center has placed portions of seven states, from Arkansas to Indiana, in their "High Risk" region for severe weather potential, and warn of the potential for long-lived strong or violent tornadoes. This is their second consecutive "High Risk" forecast day, and fourth of the year. A high risk forecast was also issued on April 27, which 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 diminish considerably on Thursday, when only a slight risk of severe weather is expected from Alabama to New York.

Joplin tornado the 7th U.S. billion-dollar weather disaster of 2011
The Joplin tornado is the 7th U.S. weather disaster of 2011 costing more than a billion dollars. With hurricane season still to come, 2011 has an excellent chance of beating 2008's record of nine billion-dollar weather disasters. The billion dollar weather disasters of 2011 so far:
1) 2011 Groundhog Day's blizzard ($1- $4 billion)
2) April 3 -5 Southeast U.S. severe weather outbreak ($2 billion)
3) April 8 - 11 severe weather outbreak ($2.25 billion)
4) April 25 - 28 super tornado outbreak ($3.5 - $6 billion)
5) Mississippi River flood of 2011 ($9 billion)
6) Texas drought ($1.2 billion)
7) Joplin tornado ($1 - $3 billion)

The New York Times has an interactive tornado fatality map showing how this year's killer tornadoes have mostly clustered over the Southeast U.S., with the glaring exception of the Joplin, Missouri tornado.
NOAA's Visualization Laboratory has an impressive animation of the satellite imagery during the month of April, showing the locations of all the tornadoes as they happened.
Helping out tornado victims
For those who want to lend a helping hand to those impacted by the widespread destruction this month'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.

listen there are 2 tornado reports w/ damage reports why wont you believe it tonight with damage reports but will believe it in the morning?
How to start your own blog, and add blog images and links
I mean it's not really a tropical weather blog, Masters barely even mentioned anything tropical it was all severe weather...that being said I think anybody should be able to talk about any weather event freely, it's the troll talk that needs to be avoided.
Yeah apparently lots of injuries thus far according to local media, and the spc storm reports seem to show that it could be a long track wedge.

Look towards the bottom of the Tornado reports
I am not trying to police anybody here. Remember though, there are people whose families are being affected by the severe weather, and they try and come here for information. If the only discussion is tropical weather, how will they ever find that information?
If you may be color blind (this image is always available so I dont know why you insist on arguing) the dots in CA are tornado reports. Here is the text that goes with them:
0018 2 S HAMILTON CITY GLENN CA 3971 12201 GLENN COUNTY SHERIFF REPORTED A TORNADO JUST SOUTH OF HAMILTON CITY.
0012 1 ENE WILLOWS GLENN CA 3952 12218 GLENN COUNTY SHERIFF REPORTED A TORNADO NORTHEAST OF WILLOWS NEAR COUNTY ROAD 36 AND U STREET. (STO)
Obviously it is important enough for the Storm Prediction Center to add them to there maps (they are in Oklahoma [there goes your conspiracy theory])
Kerry, I never, explicitly or implicitly, claimed you were a troll. I was speaking from Keeper's point of view, not my own.

EXPLODED INTO A MAJOR TYPHOON IN A SHORT PERIOD YESTERDAY.SHIPPING IN THE AREA IS WARNED TO RETURN TO PORT. WAVE HEIGHTS EXPECTED TO BE 50FT NEAR THE EYE WITH GUSTS IN EXCESS OF 160MPH.
MAY YET REACH SUPER TYPHOON STATUS WITH BOTH HIGH POLAR OUTPUT LOW WIND SHEAR AND HIGH SSTS.
EXPECTED TO TRACK NORTH OVER THE NEXT 2 DAYS.
The only thing about posting Utubes here are to be sure to use the old embed codes and bypass the image box in comments and post directly.
THE FORECAST DETAILS BECOME A BIT MORE TRICKY BY THE END OF THE
WEEKEND...AND ESPECIALLY DURING THE EARLY PORTION OF NEXT WEEK. A
PIECE OF THE ENERGY ASSOCIATED WITH THE DEPARTING TROUGH IS FORECAST
TO BE LEFT BEHIND AND CLOSE OFF TO OUR SOUTHEAST TOWARD SOUTH FL OR
THE BAHAMAS DURING THE WEEKEND. HOWEVER...GLOBAL GUIDANCE IS NOT IN
COMPLETE AGREEMENT AS TO THE EVOLUTION OF THIS ENERGY. LATEST GFS IS
FAVORING A STRONGER UPPER RIDGE AXIS OVER THE SE STATES AND AS A
RESULT FORCING MUCH OF THIS ENERGY TO STAY EAST OF THE FL PENINSULA
(AT LEAST THROUGH MONDAY). ECMWF ON THE OTHER HAND IS MORE AGGRESSIVE
IN ALLOWING THIS ENERGY TO CUT-OFF AND DRIFT BACK WESTWARD INTO THE
GULF OF MEXICO. IF THIS WERE TO VERIFY...IT COULD ENHANCE THE
POTENTIAL FOR SEA-BREEZE GENERATED CONVECTION. THIS SOLUTION WOULD
ALSO RESULT IN MORE DIURNAL CLOUD-COVER FOR OUR REGION...AND
SLIGHTLY COOLER DAYTIME TEMPERATURES. FOR NOW...WILL NOT BITE OFF ON
THE ECMWF SOLUTION AND WILL LEAN THE FORECAST CLOSER TO THE 00Z
CANADIAN WHICH ISN`T AS STRONG WITH THE RIDGE OVERHEAD AS THE
GFS...BUT ALSO NOT AS AGGRESSIVE WITH THE UPPER LOW.
Just type (img src[equal sign][URL]).
Replace the parentheses with lesser than and greater than signs, respectively. Also, don't use any spaces. Do precisely as I illustrated above.
Not an official one, but a preliminary one. Its final rating will likely be an EF-3 or EF-4.
Okay...thanks. I understand the lack of tropical talk because of all this messy terrible weather going on up near Missouri, I hope we don't have any other tornado with the intensity, power, destruction and fatality amount that the Joplin tornado did.
Preliminary rating of EF3. May have been stronger.
1.) We've had a really bad winter
2.) Really bad floods
3.) Really bad tornadoes
Makes you wonder, will our hurricane season be really bad too?
Correction it may now be dissipating
Tropical Cyclone Advisory #45
TYPHOON SONGDA (T1102)
9:00 AM JST May 26 2011
==================================
Typhoon will move at the same speed for the next 48 hours then accelerate
Typhoon will move northwest for the next 23 hours then gradually move to the north
Typhoon will keep present intensity for the next 24 hours
Final Dvorak T Number will increase to 6.5 after 24 hours
Tornado in California...only 6:40 pm there.
Looks like more of a damaging wind threat, but the squall lines can still produce tornadoes and this one looks very strong.
Dont forget the big drought in some parts of the U.S like in Texas.
No. The GFS has been developing Arlene in the eastern Caribbean. The upper flow is simply too strong (and zonal) across that area of the Caribbean, even if it is lessening.
