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)

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.

How's it going? I see that there is "tornadic" activity to the east and west of Dayon ...all okay with you?
Not here in Houston ...just hot, overcast and humid
Mom decided it was a good time to re-organize the basement food pantry. Its underground, has no windows, reinforced concrete walls on 3-sides and a sturdy ceiling... so probably a good idea. During the tornado warning, she kept busy by moving canned goods around on shelves. I guess that's as good a place to be as any.
Thats what happens when u have nuthin 2 do and time on ur hands :)
Oh I'm fine here in Ms.....just watching for others, gonna be over in your area soon.

It was a long evening and night in Indiana. Numerous warnings of all sorts. Simply terrifying skies. A couple reports of funnel clouds here in Muncie, one not more than 2 blocks from where I was at work. Fortunately, no touchdowns here. Looking over the storm reports on my local NWS site, I'm willing to bet a couple twisters touched down in some areas. Bedford, Indiana took a hit, with a dozen or so injuries and some destroyed buildings. I'm still in the fact gathering phase, and will post more as I come across information.
Hopefully these past few days was springs way of saying goodbye. Push the cold air north and let it stay there till fall. As much as I hate heat and humidity, I'm more than ready for much more predictable weather, for all of us!
Prayers for my fellow Hoosiers, and all elsewhere affected by this weeks and the past months terrible weather.
Tornadoes touch down in Southern Indiana; 12 injured in Bedford, more possibly hurt in Bloomington
Today: A 40 percent chance of showers and thunderstorms after
1pm. Some of the storms could produce gusty winds and heavy rain. Areas
of fog before 8am. Otherwise, mostly sunny, with a high near 89. Calm
wind becoming south southwest between 10 and 15 mph.
Tonight: A
40 percent chance of showers and thunderstorms. Mostly cloudy, with a
low around 67. South southwest wind between 5 and 10 mph becoming calm.
Friday: A
30 percent chance of showers and thunderstorms before 1pm. Mostly
sunny, with a high near 90. South southwest wind between 5 and 15 mph.
And I think that rain to my west is going to go just north of me unless more develops on the southern end.
you got so much rain coming.
might need another rain gauge to keep up.
paid members are better-looking, too.
:(
LOL.
I hope you have better luck.
