Deadly tornadoes rip OK, KS, and AR; high tornado risk today; Joplin tornado an EF-5

Posted by: Dr. Jeff Masters, 1:48 PM GMT on May 25, 2011

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.)

Figure 5. Radar image of an unusual "J"-shaped tendril emerging from a tornadic thunderstorm near Dallas, Texas. 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.

Latest from SPC... ...MAJOR TORNADO OUTBREAK IS UNDERWAY... BASED ON LATEST TRENDS IN TORNADIC SUPERCELL EVOLUTION HAVE MADE A NWWD ADJUSTMENT TO HIGH RISK ACROSS MO. RADAR AND DIAGNOSTIC DATA SUGGEST A SIGNIFICANT TORNADO RISK EXTENDS ALONG THE WARM FRONT DRAPED ALONG THE I-70 CORRIDOR FROM CNTRL MO...EWD INTO THE STL AREA. FOR THIS REASON HAVE INCREASED THE PROBABILITY FOR SIGNIFICANT TORNADOES TO ACCOUNT FOR NUMEROUS...POTENTIALLY LONG-TRACK AND DAMAGING TORNADOES SPREADING ACROSS ERN MO TOWARD WCNTRL/SRN IL. ADDITIONALLY...CU FIELD IS EXPANDING/DEEPENING ACROSS MUCH OF AR AND SCT-NUMEROUS TORNADIC SUPERCELLS SHOULD EVOLVE OVER THIS REGION THEN SPREAD INTO WRN TN/KY BY EARLY EVENING.

Quoting Tropicsweatherpr: There are some scattered showers to the east of you.Looks like the air is more moist in the Central Caribbean part. Indeed. We did have about an inch and a half of rain over the past couple of days which was really welcome but have since returned to dry conditions as the ULL that was over the Yucatan channel lifted out. The models are showing moisture coming back to the NW Caribbean over the next several days. Member Since: August 19, 2006 Posts: 0 Comments: 14939

Hi all! I'm a long time follower, but finally decided to join up! Hoping the boards won't be as volatile this season! :) I don't want to seem unconcerned about the Midwest (I hope for the best for all who may be impacted), but I have a hurricane question. If I recall, the drier the month of May has been in South Florida, the more likely it is for tropical activity to strike later during the season. Is this correlation a supported one? If so, what will that mean for an area that is 5 inches under average rainfall for the month? Thanks! Member Since: May 23, 2011 Posts: 0 Comments: 0
