A dangerous tornado outbreak is expected on Saturday over the Plains, says NOAA's Storm Prediction Center (SPC). Warm, moist air flowing northwards from a Gulf of Mexico that has record-warm waters will collide with cold air funneling down from Canada, creating a highly unstable air mass capable of creating strong thunderstorm updrafts. An impressive upper-level low, accompanied by a jet stream with 105 - 125 mph winds at middle levels of the atmosphere, will create plenty of wind shear, giving the air the spin it needs to form tornadoes. SPC has has issued their highest level of alert, a "High Risk," for much of Oklahoma, Kansas, and Nebraska for Saturday. Included in the "High Risk" area are the cities of Wichita, Oklahoma City, and Lincoln. This is the second time SPC has issued a "High Risk" forecast this year; the first "High Risk" forecast came for the March 2 tornado outbreak, which killed 41 people and did $1.5 - $2 billion in damage. It is very unusual for SPC to issue a "High Risk" forecast more than a day in advance of a suspected tornado outbreak; according to Wikipedia, today's "High Risk" forecast is only the second time SPC has ever done this. The other instance was for the April 6 - 8, 2006 tornado outbreak focused over Tennessee, which generated 73 tornadoes that killed 13 and did $1.5 billion in damage. People living in the threatened area need to pay close attention on Saturday to this dangerous severe weather situation.

Gulf of Mexico water temperatures the warmest on record
Temperatures in the states bordering the Gulf of Mexico were the 3rd - 7th warmest on record during the first three months of 2012, according to NOAA's National Climatic Data Center. This allowed Sea Surface Temperatures (SSTs) in the Gulf of Mexico (25 - 30°N, 85 - 90°W) to climb to 1.4°C (2.5°F) above average during March 2012, according to a wunderground analysis of the Hadley Centre SST data set. This is the warmest March value on record for the Gulf of Mexico, going back over a century of record keeping. During the first two weeks of April, Gulf of Mexico waters remained about 1.5°C above average, putting April on pace to have the warmest April water temperatures on record. Only one year in the past century has had April water temperatures in the Gulf of Mexico more than 1.1°C above average; that year was 2002 (1.4°C above average.) All that record-warm water is capable of putting record amounts of water vapor into the air, since evaporation increases when water is warmer. Because moist air is less dense than dry air, this warm, moist air flowing northwards from the Gulf of Mexico into the developing storm system over the Plains will be highly unstable once it encounters cold, dry air aloft. The record-warm waters of the Gulf of Mexico are a key reason for the high risk of severe weather over the Plains this weekend.

April Storms (llpj04)
this storm greeted me as I came out of the grocery store, chased me home and got to my driveway the same time I did.

Last night we had a pretty spectacular lightning storm. I put the camera on the tripod in time-lapse mode and laid on my back on the hillside above the pond taking in an amazing show. When it got more exciting than I was comfortable with, I ran for the house.

Looks like Oklahoma storms are clearing out this morning, if the day heating arrives, lookout, and Katie bar the door!

It's not a good day for some, I am going to come in here throughout the day and see some of the most wonderful post the members will have to say.

Neopolitan: I like your cut and paste of Dr. Forbes it's great.

I saw Dr.Forbes and Mike Bettes at a weather seminar,
both are good down home folks, easy to talk too!

This looks like a similar setup to the record tornado outbreak WI had April 10, 2011. Statewide 15 were recorded with 10 of them being in EC WI.

Good morning to all. I have a feeling that there will be many flood advisories popping up in Puerto Rico today.And the so far wet 2012 continues here.

.HYDROLOGY...RAIN WILL FALL THROUGH THE DAY PRETTY MUCH OVER THE
WHOLE ISLAND AND THE USVI ESPECIALLY LATE TODAY THROUGH MIDNIGHT
TONIGHT. RAINFALL ACCUMULATIONS ARE EXPECTED TO AVERAGE BETWEEN
ONE TO TWO INCHES NORTH OF THE CORDILLERA WITH THE HEAVIEST
AMOUNTS ACROSS NORTHEAST PR. SOUTH OF THE CORDILLERA AMOUNTS WILL
BE GENERALLY LESS THAN ONE INCH. WHILE THERE IS SOME CONCERN FOR
FLOODING ESPECIALLY ACROSS NORTHEAST PR WHERE THE HEAVIEST AMOUNTS
ARE EXPECTED...THESE AMOUNTS ARE EXPECTED TO FALL OVER A 12-HR
PERIOD AT MODERATE INTENSITY. ALSO THE PROGRESSIVE NATURE OF THIS
FRONT ARGUES AGAINST SIGNIFICANT RAINFALL ACCUMULATIONS. WHILE
RISES CAN BE EXPECTED IN SOME OF THE RIVERS IN THOSE AREAS ALREADY
MENTIONED. THE PROB OF FLASH FLOODING SEEMS TOO LOW ATTM TO
WARRANT A FLASH FLOOD OR A FLOOD WATCH. HOWEVER...DO EXPECT TO SEE
SOME STREET FLOODING AND SOME FLOODING IN POOR DRAINAGE AREAS.

Tornado plows through Norman

A tornado Friday afternoon cut an eight-mile path through Norman, snapping power poles, uprooting trees, damaging buildings and causing minor injuries as residents braced for the potential of even more severe weather throughout the weekend.
“It is surprising you don't have more injured with the time of day, about 4:02,” Deputy Norman Fire Chief Jim Bailey said. “Norman is a busy town. There were a lot of people out driving around, and we had very little notification.”
Cleveland County was in a tornado watch minutes before the twister suddenly touched down at Interstate 35 and W Lindsey Street. It hopscotched through the center of town, ripping the roofs off buildings and raking a park near the city's municipal complex before fading out in the northeast side of the city near Robinson and 12th Avenue NE. Thousands lost electricity.
A tornado warning was issued at 3:59 p.m., the tornado touched down three minutes later, and the first damage was reported at 4:07 p.m., said Rick Smith, a National Weather Service meteorologist.
At least 18 people were taken to Norman Regional Hospital with minor injuries like scrapes and bruises, said Kelly Wells, hospital spokeswoman.
One person was admitted to the hospital, and the others were treated and released, she said.
One person was treated and released at the Health Plex in Norman. Everyone had minor injuries. The person admitted to the hospital was in fair condition as of 10:30 p.m. Friday.
Wells said hundreds of people sought shelter at the hospitals in Norman. This can cause problems for the hospital as they try to treat patients.
“If they can't find shelter elsewhere, we would encourage them to do that, but we wouldn't turn them away,” Wells said.
Two of the injured were in a vehicle when the tornado hit and another was hit by debris, Bailey said.
The strength of the tornado was not immediately calculated, but the damage pattern seemed to indicate the tornado was not of the most powerful variety.
Atmospheric conditions Saturday will be ripe for more tornadoes and other severe weather, the National Weather Service said.
“The bottom line is, be ready for it. It may happen in one place or it may happen across a huge part of the state, but it only takes one tornado and one storm,” Smith said.
Severe thunderstorms are possible throughout the state Saturday, but the Oklahoma City area and most of the middle third of the state are in an area deemed at the highest risk.
Storms are expected to form in the late afternoon or early evening and track across the state, forecasters said. Tornadoes, damaging straight-line winds, lightning, hail and flooding rain are possible.
“If everything comes together like it could, it could be a serious situation for parts of Oklahoma,” Smith said.
‘There was a roar'
In Norman on Friday, the University of Oklahoma had no reports of damage, a spokeswoman said, but other areas weren't so lucky.
Smith said the most significant structural damage was found near the hospital at N Porter Avenue and E Robinson Street. Bailey said the tornado ripped the trees out at Andrews Park near the municipal complex.
Philip DeFatta, owner of Leon Pierce Body Shop, 521 N Porter, said he took cover inside his shop. While he did not hear the tornado, he heard the medical records building next door explode.
“It's gone,” he said. “The roof's gone. It's all over the place. The front wall is down. Part of it is in my building.”
He said the storm moved around cars in his parking lot, but his auto repair building is intact.
DeFatta said he does not believe anyone was in the medical records building when it was hit. “The police have been all through it, looking,” he said.
The tornado downed power lines, trapping numerous motorists in their cars on 24th Avenue SW between W Lindsey Street and W Brooks Street.
Oklahoma Gas and Electric Co. and firefighters worked to the clear downed power lines and free trapped motorists.
Robert Ruiz, of Norman, said he and his family had about three minutes between the time they heard the announcement to seek shelter and the time storm hit downtown.
Ruiz, a partner with Enye Media at 301 1/2 E Main St., said the storm ripped off his back door and threw it about 25 feet after he, his wife and four children rushed to take cover there.
As they hunkered down in the middle of a recording studio in the business, they saw heavy rain and debris flying past the window.
“It was raining hard, and then all of a sudden, everything went sideways,” Ruiz said. “All the rain went sideways, and we starting seeing debris. There was a roar, and the kids got really scared of the situation. They had their heads down and their hands on the back of their heads, and they started crying.”
The chaos lasted about a minute, he said.
OG&E reported 4,000 customers without power in Norman, 1,500 in Oklahoma City and 1,500 in Piedmont about 6 p.m. Friday.
Norman city officials canceled household hazardous waste collection scheduled for Saturday, though a spring cleanup will continue as planned.
Elsewhere Friday evening in Oklahoma, there were preliminary reports of a tornado north of Altus near the Blair community in Jackson County, one near Cooperton in the eastern Kiowa County and another tornado south of Carnegie in western Caddo County. Those reports had not been confirmed as of 9 p.m. Friday, the weather service said.
Emergency response
Emergency responders throughout Oklahoma began to organize this week in anticipation of the Saturday storms, state Emergency Management Department spokeswoman Keli Cain said. The agency plans to open its emergency operations center by 3 p.m.
Authorities are coordinating with local emergency management officials, meteorologists, law enforcement officers, paramedics, firefighters and others in preparation for the storms, Cain said.
Similar advance planning was under way Friday in cities across the state. Officials in nearly every department in Oklahoma City were meeting to go over plans and procedures, city spokeswoman Kristy Yager said.
Officials' priorities are ensuring every method of informing the public about weather conditions is used effectively, and to coordinate a fast response to help people in areas affected by any tornadoes and other severe weather.

Small tornado reportedly hit Mustang early Saturday

5:30 a.m. Possible tornado hit Mustang about 12:45 a.m., said meteorologist Bruce Thoren at the National Weather Service in Norman. Damage reported to homes. A roof was blown off one home. A mobile home was damaged. Damage was between Mustang and Czech Hall roads between SW 59 and SW 15.
3:30 a.m. MUSTANG – A small tornado touched down and caused damage to homes and knocked out power early Saturday, a police dispatcher said.
Power poles were toppled at Mustang Road and SW 59. The city was without power, the dispatcher said.
Resident Jack Friese wrote in an e-mail to NewsOK.com that the tornado hit without any warning 40 feet from his parents' house. They were not hurt, he said. Friese said their neighbors' house was heavily damaged, and the only room intact was the bedroom where the neighbors' were sleeping.
Damages to homes were reported in the Branches housing addition near Geronimo and Ponderosa. Firefighters and police officers were searching neighborhoods in the area. There are no immediate reports of injuries, but at least one ambulance was requested to take a person to Integris Canadian Valley Hospital in Yukon, according to Mustang fire radio reports.
The police dispatcher said traffic is being kept out of the area around Mustang Road where power poles are down. There are also power outages in west Oklahoma City and Yukon. At 4:30 a.m. 3,347 customers were without power in west Oklahoma City and another 1,264 customers affected in Yukon, Oklahoma Gas & Electric Co. website shows.
Also, a tornado warning was issued for a line from northeast Canadian County, northwest Oklahoma County and southwest Logan County as a round of storms moved northeast into Payne County.

Radiation discharge near Philadelphia kept secret from public for weeks — No ‘immediate’ health concerns, says NRC

Title: NRC reveals radioactive water spill at Limerick nuke plant
Source: The Mercury
Author: Evan Brandt
Date: April 13, 2012

“Several thousand gallons” of water containing as much as five-times the government’s “safe” level of radioactive tritium was accidentally released at Exelon Nuclear’s Limerick Generating Station last month and then flushed into the Schuylkill River, The Mercury learned Thursday.

Public Kept in Dark Due to Unclear, Voluntary Reporting Requirements Set by Industry

However the concentrations of contamination in the water were considered so low that they presented “no immediate health and safety concerns,” according to the Nuclear Regulatory Agency, which is why the incident was not reported publicly until 23 days after it happened.
“When formal notifications are made to the state, we expect to receive a written notification to us [...] The company initially said it wasn’t clear whether such a submittal was needed (under the reporting requirements of NEI voluntary Groundwater Protection Initiative) [...] But we insisted that it was needed, and the company ultimately agreed.” -NRC spokesman Neil Sheehan

“Routine”


It was 3 a.m. Monday, March 19 when “a manhole cover overflowed during a scheduled and permitted radiological release,” according to an incident report posted on the NRC web site.
“several thousand gallons of water [...] was discharged” through a permitted discharge to Possum Hollow Creek, which flows from the plant grounds into the Schuylkill River,” according to information from the NRC.
Exelon estimated something less than 15,000 gallons, was legally dumped into the Schuylkill River, which is a drinking water source for several downstream communities, including Phoenixville and Philadelphia.
“It’s important to note that the Limerick and other nuclear power plants routinely release slightly radioactive water to the river, but the releases must be controlled and any levels of radioactivity well within allowable limits,” [NRC's] Sheehan wrote.

“Slightly Radioactive”?


NRC spokesman Neil Sheehan wrote in an e-mail that the “maximum level of radioactivity detected in Possum Hollow Creek . . . on the day of the event was 495 picocuries per liter of tritium.”
One water sample collected from a puddle near the manhole from which the water first emerged, had a tritium concentration of 113,000 picocuries per liter [Several thousand gallons released]


“Regardless, we made the courtesy notifications because we like to keep stakeholders and community members informed” -Dana Melia, communications manager for the Limerick Generating Station

Awesome photo I took last June of a supercell thunderstorm over Oklahoma. Note the rotating of the base and the overshooting cloud tops. Thought it would be cool to show everyone the best weather photo I have ever taken in honor of my 1000th comment on the blog :D Looking forward to many more in the future!

It's WeatherEmergency time: extremely low tendency to give a shout-back.
Plus we don't really operate on realtime here. People are reading on&off, on&off...
The only way to see if anybody responded is to wait an hour or several, then scroll to your comments in the back pages to check for 'plus'es.
