National Weather Service Norman, Oklahoma
National Weather Service - Norman, Oklahoma is a Weather Forecast Office of the National Weather Service based in Norman, Oklahoma, which is responsible for forecasts and the dissemination of weather warnings and advisories for central and most of western Oklahoma, with the exception of the panhandle. It is located in the National Weather Center on the University of Oklahoma campus, where it acts as one of the NOAA Weather Partners, a group of close-together weather-related agencies of the National Oceanic and Atmospheric Administration. NWS Norman is currently overseen by David Andra, who serves as the Meteorologist In Charge of the office.
The Norman Weather Forecast Office – which operates as a branch of the National Weather Service's Southern Region Headquarters division – manages three NEXRAD Doppler weather radar sites that cover its area of forecasting responsibility, based in Oklahoma City, serving central Oklahoma; Frederick, serving southwestern Oklahoma; and at Vance Air Force Base, serving north-central and northwestern parts of the state. The office has earned widespread recognition from local media outlets, especially in concern with certain weather conditions that are or are forecast to occur. It has also received attention from national media, and was even recognized and visited by United States President Barack Obama.
The U.S. Weather Bureau created the Central Oklahoma forecast office on November 1, 1890; it was originally based in Oklahoma City at the Overholser Opera House, on the southeast corner of Robinson Avenue and Grand Boulevard in the city's downtown district. Twelve years later, the Weather Bureau relocated the Oklahoma City office's operations to the Culbertson Building, at the southeast corner of Grand and Broadway Avenue, where it began operating from on July 1, 1902.
The offices at the Culbertson Building was closed four years later on January 16, 1906, with the operations moving once again, this time to a newly constructed weather observatory located at 1923 Classen Boulevard in southwest Oklahoma City. In 1932, the office began to slowly migrate its forecasting operations and other functions from the observatory to a new Weather Bureau office based in an existing building at Will Rogers Airport on the city's southwestern edge, which opened on April 2 of that year. Eventually, an actual proprietary building to solely house the Weather Bureau office was constructed at the airport, where it moved on October 22, 1965. Shortly afterward, the U.S. Weather Bureau was renamed the National Weather Service. On January 27, 1987, the National Weather Service moved its central Oklahoma office away from Oklahoma City, and relocated its operations into a building that had been constructed specifically for NWS use in Cleveland County, at Max Westheimer Airport in Norman.
The National Severe Storms Laboratory followed the central Oklahoma office there in 1990. Then, in October 1995, the National Severe Storms Forecast Center – was subsequently renamed the Storm Prediction Center – migrated its operations from Kansas City, Missouri to a wing of the Max Westheimer Airport campus. On August 7, 2006, the National Weather Service office, the Storm Prediction Center and the National Severe Storms Laboratory began moving their respective operations into the newly constructed National Weather Center building on the southern portion of the University of Oklahoma's Research Campus.
Under NOAA operational guidelines for such situations, responsibility over the issuance of forecasts – both routine and short-term – and weather alert products can be transferred to the National Weather Service office in Tulsa in the event of an outage or an emergency necessitating the enactment of evacuation procedures for NWS and guidance center personnel that affects the Norman campus.

Forecasting at the Storm Prediction Center at the National Weather Service
John Hart, lead forecaster at the Storm Prediction Center, part of the National Weather Service in Norman, Oklahoma, gives CNET's Daniel Terdiman an an up-close look at how the federal government evaluates ever-changing weather in the Continental United States in order to forecast the kinds of storms -- tornadoes and severe thunderstorms, for the most part -- that cause the most danger to people's lives and property. Oklahoma, of course, is in the heart of Tornado Alley, the area of the Great Plains that is the most-frequently hit by those most destructive of weather events.
The Storm Prediction Center is part of the National Weather Service, and is funded by NOAA, the National Oceanic and Atmospheric Administration.

Tornado Outbreak May 20th 2019 across the Texas Panhandle and Oklahoma
Monster severe storms struck the central United States once again, sparking life-threatening impacts such as long-track tornadoes and flash flooding across the region through Monday night.
The National Weather Service Storm Prediction Center (SPC) issued a high risk for portions of Oklahoma and Texas, the first time a high risk warning has issued by the agency since May 2017. The severe outbreak was the highest tornado risk since April 14, 2012.
Storms on Monday produced golf ball-sized hail and strong wind gusts across the Texas Panhandle and Oklahoma.

Twin Tornadoes Touch Down In Nebraska
Original file date: Mon, 16 Jun 2014, ID:tp0l4m
PILGER, Neb. — A storm packing rare dual tornadoes tore through a tiny farming town in northeast Nebraska, killing two people, crumpling grain bins like discarded soda cans and flattening dozens of homes. Pilger’s 350 residents evacuated their homes after the powerful twisters slammed the area Monday afternoon. Nebraska State Patrol closed all roads into town. “More than half of the town is gone — absolutely gone,” Stanton County Commissioner Jerry Weatherholt said. “The co-op is gone, the grain bins are gone, and it looks like almost every house in town has some damage. It’s a complete mess.” Larry Nelson, 73, has lived in Pilger, about 80 miles northwest of Omaha, for 23 years. He rode out the storm in his neighbor’s basement, emerging later to find his home completely gone. “I’m grateful I was over there,” Nelson said. Another resident, Trey Wisniewski, said first his weather radio alerted him, then the power went out and the tornado sirens started to sound. The sky went black and he and his wife took their pets into the basement. “My wife was holding our animals and I was holding on to my wife. We could feel the suction try to pull is out of there,” said Wisniewski, 43. “It wasn’t raining. It was raining debris.” Stanton County Sheriff Mike Unger estimated that 50 to 75 percent of Pilger was heavily damaged or destroyed and the school was likely beyond repair. The storm was part of a larger system that tracked across the nation’s midsection Monday. More storms are forecast for Tuesday, stretching from eastern Montana to New York, but the system likely won’t be as powerful as on Monday, said Steve Corfidi, lead forecaster at the Storm Prediction Center in Norman, Oklahoma. The greatest risk for tornadoes will be in the Dakotas, eastern Montana and northeastern Wyoming. Hail is expected west of the Mississippi River, while damaging winds could down some trees in upstate New York, Corfidi said. Stanton County Sheriff’s deputy Josh Bennett said a 5-year-old girl was killed in Pilger on Monday. Bennett did not identify the child further or provide details about her death. Unger said Tuesday that a motorist also died in a single-vehicle accident just east of Pilger as the storm pounded the area. State patrol confirmed that a male driver died in Cuming County. At least 19 people were taken to hospitals. The National Weather Service said the two twisters touched down within roughly a mile of each other. Crews planned to examine the area Tuesday to determine the intensity of the unusual twin tornadoes, said Barbara Mayes, a meteorologist with the National Weather Service in Valley. “It’s less common for two tornadoes to track together for so long, especially with that same intensity,” she said. “By no means is it unprecedented. But we don’t see it often.” Residents were poised to return Tuesday morning to survey the damage and gather valuables. Sheriffs said law enforcement would escort residents to their properties. Jodi Richey, a spokeswoman for Faith Regional Health Services in nearby Norfolk, said 16 people were treated there. Some were in critical condition but others were treated and released. Providence Medical Center in Wayne treated three tornado victims, including two who had lacerations, said hospital spokeswoman Sandy Bartling. Two were released Monday evening, and the third was in stable condition. Authorities said the first tornado touched down around 3:45 p.m. and downed several power lines before it leveled a farmhouse. The second tornado was spotted southwest of Pilger, according to the Stanton County Sheriff’s Office. Shortly afterward, the town suffered a “direct hit” that leveled several buildings, including the Fire Department building. Nebraska Gov. Dave Heineman declared a state of emergency, and the National Guard was prepar...

Tornado Storming Over 5 States
The National Weather Service placed parts of five storm-battered states -- Oklahoma, Kansas, Missouri, Arkansas and Texas -- under a tornado watch Monday afternoon, meaning that conditions were favorable for tornadoes to develop within the next few hours.
The five-state area is in the heart of a storm system hovering over the Plains and Midwest all the way to Minnesota.
On Sunday, a tornado packing winds as high as 200 mph, left two people dead in Oklahoma. Tornadoes and high winds injured more than 20 in the region.
The body of 79-year-old Glen Irish was found in an open area of the neighborhood after a twister slammed into Shawnee, Okla., leveling a mobile home park.
The Oklahoma medical examiner on Monday confirmed the second fatality, Billy Hutchinson, 76.
Both victims were from Shawnee, but it was not immediately clear if both lived in the Steelman Mobile Home Park, which was destroyed.
You can see where there's absolutely nothing, then there are places where you have mobile home frames on top of each other, debris piled up, Pottawatomie County Sheriff Mike Booth said after surviving damage. It looks like there's been heavy equipment in there on a demolition tour.
It's pretty bad. It's pretty much wiped out, Booth said.
More than 60 million Americans are at risk of severe storms Monday, with the primary targets including Oklahoma, Kansas, Missouri and Arkansas, the National Weather Service's Storm Prediction Center warned.
Damaging wind gusts, large hail and tornadoes are possible in all areas, Weather Channel meteorologist Kevin Roth said.
Oklahoma City, Tulsa, St. Louis, Cedar Rapids, Iowa, and Minneapolis are among the cities most at risk for severe weather Monday, AccuWeather meteorologist Meghan Evans said. Chicago, Detroit, Dallas and Indianapolis also are in the danger zone.
Sunday, there were 24 reports of tornadoes in five states, the Storm Prediction Center said. In what has otherwise been a quiet spring for tornadoes, May 19 appeared to have been the second-most active day for tornadoes in the nation so far in 2013, Weather Channel meteorologist Jon Erdman said.
So far this year -- not including this most recent five-day outbreak -- severe storms have caused $3.5 billion in economic losses in the USA, says meteorologist Steve Bowen of global reinsurance firm Aon Benfield. Bowen says. Of that $3.5 billion, at least $2 billion was covered by insurance.
By the time the current storm system finally winds down by the middle of this week, I wouldn't be surprised if this ends up as the costliest U.S. natural disaster event we've seen so far in 2013, said meteorologist Steve Bowen of global reinsurance firm Aon Benfield.
Recent full-year severe weather-related insured losses were roughly $27 billion in 2011 and $15 billion in 2012 -- the two costliest years on record, Bowen said. By this definition, severe weather means damage from thunderstorms or tornadoes, and does not include damage from hurricanes.
The storms in Oklahoma on Sunday that ripped off roofs and tossed big trucks like toys were part of a severe weather outbreak that stretched from Texas to Minnesota. Twisters were also reported Sunday in Iowa and Kansas.
The killer tornado that flattened portions of Shawnee, Okla., had wind speeds that were estimated as high as 200 mph, according to the National Weather Service in Norman, Okla.
The NWS said preliminary information from a survey team indicated EF4 damage at the scene.
EF4 is the second-highest level on the Fujita Scale of Tornado Intensity. EF4 tornadoes have wind speeds that are estimated at between 166-200 mph.
Across Oklahoma, 21 people were injured, not including those who suffered bumps and bruises and chose not to visit a hospital, said Keli Cain, a spokeswoman for the Oklahoma Department of Emergency Management. Booth said six at Steelman Estates were hurt.
Gov. Mary Fallin declared an emergency for 16 Oklahoma counties.
Interstate 40 was closed by the Oklahoma Highway Patrol after winds overturned semi-tractor trailer trucks and other vehicles, Newsok.com reported.
KFOR-TV showed footage of homes damaged and cars and trucks flipped from highways near Shawnee. Other video showed flashes from electrical transformers blowing out as they were hit by high winds or debris from the tornado near Edmond.
A tornado touched down in Golden City, Mo., early Monday morning and tore through two counties, Barton County Emergency Management Director Tom Ryan told CNN. The number of injuries and extent of damage were not immediately clear.
Sedgwick County, Kan., emergency management director Randy Duncan said officials are grateful for few reports of damage from a tornado that touched down near Wichita Mid-Continent Airport. He told CNN the area emerged relatively unscathed.''
Forecasters had been warning for days that severe storms were likely across the region.

May 20th 2013 Massive Tornado Kills Dozens in Oklahoma America
A massive tornado carrying winds of up to 320 kph has torn through the Oklahoma City suburb of Moore, ripping up at least two schools and leaving a wake of tangled wreckage.
At least 50 people are dead, including seven children in a school which collapsed during the storm. Seventy-five children took shelter there from the tornado in the town of Moore. Up to two dozen are still believed to be trapped under the rubble after Monday's 3-km-wide tornado.
President Barack Obama spoke with Oklahoma Governor Mary Fallin, expressing his concern for those who have been affected and promising all available assistance.
At a press conference in Oklahoma City, Fallin said that additional resources have been called in from out of state, including rescue dogs, as it will be dark pretty soon and we want to do everything that we can to continue to look for those that might be lost in this tragedy.
She encouraged civilians to stay away from the disaster-struck areas and to leave the work of search and rescue to emergency personnel.
Television video showed tracts of homes destroyed, cars tossed about and piled atop one another, and at least one building on fire.
Rescue workers were pulling third-graders from a severely damaged elementary school in Moore, a KFOR television reporter said from the scene, and aerial video showed first responders sifting through the rubble left behind.
The National Weather Service assigned the twister a preliminary ranking of EF4 on the Enhanced Fujita Scale, meaning Monday's was in the second most powerful category of tornado.
It seems that our worst fears have happened today, said Bill Bunting, National Weather Service meteorologist in Norman, Oklahoma.
The massive twister struck at the height of tornado season, and more were forecast. On Sunday, tornadoes killed two people and injured 39 in Oklahoma.
Witnesses said Monday's tornado appeared to be more fierce than those that tore up the region on May 3, 1999, killing more than 40 people and destroying thousands of homes. That tornado ranked as an EF5, meaning it had winds over 320 kph.
Unknown number of survivors
Officials at two hospitals in the area said they've been treating more than 140 patients, including about 70 children.
We have many injured and we're just trying to work out how bad it is right now, said a woman who answered the phone at the Moore city manager's office.
Al Jazeera's John Hendren, reporting from Oklahoma City, said the number of injuries remains unknown as the roof of the Moore Medical Centre has been completely ripped off of the building and that survivors will have to be taken to nearby towns for treatment.
The injuries could go beyond those sustained directly as a result of the tornado.
There are hundreds of people walking through the streets, said Hendren.
The emergency officials here have been so busy dealing with the search that they're having a hard time keeping people from combing through the wreckage, and, of course, that remains dangerous.
The National Weather Service predicted a 10 percent chance of tornadoes in parts of Texas, Oklahoma, Arkansas, Kansas, Missouri and Illinois. It said parts of four other states - Wisconsin, Indiana, Michigan and Iowa - have a 5 percent risk of tornadoes.
The area at greatest risk includes Joplin, Missouri, which on Wednesday will mark two years since a massive tornado killed 161 people.
The latest tornado in Oklahoma came as the state was still recovering from a strong storm on Sunday with fist-sized hail and blinding rain.
Two men in their 70s died in the storm, including one at a mobile home park on the edge of the community of Bethel Acres near Oklahoma City, said Keli Cain, a spokeswoman for the Oklahoma Office of Emergency Management.
Thirty-nine people were injured around the state as storms toppled trees and tore up rooftops, she said.
Several hundred homes and buildings were thought to have been damaged or destroyed and approximately 7,000 customers were left without power in Oklahoma. There is definitely quite a bit of damage, Cain said.
Oklahoma Governor Mary Fallin declared 16 counties disaster areas.
More than two dozen tornadoes were spotted in Iowa, Oklahoma, Kansas and Illinois, according to the National Oceanic and Atmospheric Administration and local news reports. Hail stones, some as large as baseballs, were reported from Georgia to Minnesota, NOAA said.
The tornado season in the United States had been unusually quiet until last week, when a tornado struck the town of Granbury, Texas, killing six people.
Explaining 2015 Tornado Season's Late But Deadly Start
After some of the quietest three months of a U.S. tornado season in 60 years, severe thunderstorms and tornadoes ripped through Oklahoma and Arkansas yesterday.
A damaging tornado touched down outside Tulsa, Oklahoma, on March 25.
One person was killed and several were injured when the tornado destroyed a mobile home park. A small twister was also reported in Moore, the Oklahoma City suburb that has been repeatedly ravaged by deadly twisters this decade.
According to the National Weather Service's Storm Prediction Center in Norman, Oklahoma, the two weak tornadoes ended a long dry streak for the 2015 tornado season.
For only the second time since the 1950s the first three weeks of March were tornado-free throughout the United States.
The center reported that a typical March sees about 120 twisters in the state.
The Last Major Great Plains Tornado Outbreak: April 14, 2012
April 13, 2012: the 1730 UTC Day 2 convective outlook issued by the Storm Prediction Center upgraded from Moderate Risk to an exceedingly rare Day-2 “High Risk” –only the second such in the SPC’s history—as concerns for a major Great Plains tornado outbreak loomed.
By morning on the 14th, a warm front had begun gradually lifting northward from the southern Plains, transporting an abundance of moist air into the region from the Gulf of Mexico. The front eventually stalled over south-central Nebraska and southern Iowa, and would serve as a focus for severe thunderstorm activity, and numerous tornadoes.
By midafternoon, the atmospheric environment farther south over Kansas and Oklahoma had become extremely volatile, as the states baked in mid-70 to 80 degree temperatures and 70-degree dewpoints east of a sharp dryline positioned over the western portions of the Plains. This feature would serve as the western boundary and second storm initiating mechanism for what would indeed become another classic Great Plains tornado outbreak.
By the end of the day, over 150 tornadoes had been reported, with the majority occurring across central Kansas. Several significant tornadoes occurred, including a long-tracked EF-4 tornado that began near Lyons and (thankfully!) lifted just southwest of Salina. Later in the evening, an EF-3 tornado caused extensive damage to areas just outside of Wichita, including the communities of Haysville, Oaklawn, and El Dorado, as well as McConnell Airforce Base (which is all-too familiar with violent tornadoes; see also April 26, 1991). Farther west, the town of Woodward, Oklahoma, was struck by a long-tracked EF-3 tornado just after midnight. Sadly, this tornado was responsible for six fatalities and twenty-nine injuries.
This video features the prolific supercell that spawned numerous tornadoes across north-central Oklahoma into south-central Kansas, near the towns of Ingersoll, Cherokee, and Manchester, OK, and Bluff City, KS. This is the same storm responsible for considerable damage in south Wichita and McConnell AFB later in the evening.

Around the Bureaus: Forecasting the Ferocious
Forecasting the Ferocious: The Predictive Science Behind NWS Forecasts for Tornadoes and Floods
Greg Carbin, Chief of Forecast Operations for the NWS Weather Prediction Center, NOAA
Despite tremendous advances in technology, meteorological prediction is still a mix of art and science. This presentation will describe the challenges of forecasting Nature's most destructive and deadly storms. The Department of Commerce's NOAA National Weather Service (NWS) Storm Prediction Center (SPC), in Norman, Oklahoma, is the nation's leading operational center for tornado and severe thunderstorm forecasting. The talk will focus on how our scientific understanding of thunderstorm formation is used at SPC to predict the occurrence of tornadoes through human pattern recognition and massive data assimilation. Similar techniques are also applied to the challenge of predicting deadly flash flood events. The NWS Weather Prediction Center (WPC), in College Park, Maryland, is the operational hub and center of expertise responsible for heavy precipitation prediction. The talk will conclude with a look at the many other services provided by WPC, as well as a summary of the six other National Centers for Environmental Prediction located in the D.C. area, Boulder, Miami, and Kansas City.

Tornadoes strike central US, killing 2 in Oklahoma
OKLAHOMA CITY (AP) -- A powerful storm front rumbled through parts of the Plains, Midwest and South on Sunday, spawning deadly tornadoes and heavy hail and rain, and damaging or destroying structures in several states.
A tornado killed two people in Quapaw, a small community in northeastern Oklahoma, near its borders with Kansas and Missouri, Ottawa County sheriff's dispatcher Colleen Thompson said. She said the twister hit the city at around 5:30 p.m. and that the extent of the damage was still unknown.
Keli Cain, a spokeswoman for Oklahoma Department of Emergency Management, said agency staff members were headed to the Quapaw area to assess the damage. She said a local official reported that Quapaw's fire station was heavily damaged.
We're hearing that there's quite a bit of damage to the north side of town, Cain said.
Tornado warnings, which indicate the greatest threat of a strike, were in effect for parts of northwest Mississippi and western Missouri as of 6 p.m. CDT. In addition to the tornado strike in Oklahoma, twisters also had reportedly touched down Sunday in Nebraska, Iowa, Kansas and Missouri.
A funnel cloud touched down northwest of Joplin, Mo., where a massive tornado in May 2011 killed 161 people, injured many others and leveled a large swath of the city. Sunday's twister wasn't expected to hit Joplin, the weather service reported.
A tornado reportedly caused damage in or near Baxter Springs, Kan., which is in the state's southeast corner near its borders with Oklahoma to the south and Missouri to the east.
Central Arkansas, including the Little Rock area, was a high risk of severe storms later Sunday, reported the National Weather Service's Storm Prediction Center in Norman, Okla.
Forecasters also asked people to be alert Sunday for possible tornadoes in a wide swath of the Midwest and south, stretching from Omaha, Neb., south to Texas and east to northern Louisiana and Mississippi.
The greatest risk for a few intense tornadoes will exist across much of Arkansas perhaps into western and central Missouri, a weather service advisory said.
The first reported tornado from the storm system touched down Sunday afternoon in a rural area in central in Nebraska. The weather service said it remained on the ground for only a short time, and there were no immediate reports of damage.
Tornado watches -- which means twisters could develop but aren't an immediate threat -- were in effect for states as far west as New Mexico and as far east as Tennessee, and the system produced storms that were moving through the region in waves. Watches were also issued for Kansas, Missouri, Mississippi, Nebraska, Iowa, Arkansas, Oklahoma, Texas and Louisiana.
Areas that don't get tornadoes could still get buffeted by hail and powerful straight-line winds. Forecasters warned of hail stones as big as baseballs and wind gusts that could reach hurricane-force -- 75 mph or higher.
Gusts of up to 60 mph were registered during a story that hit southeastern Iowa on Sunday that damaged several buildings, including a barn that injured someone when it was blown over.
Earlier Sunday afternoon, a strong line of storms moved through west-central Missouri, bringing winds that reached 70 mph hour near Chillicothe, Mo., that toppled some trees.
The Missouri Highway Patrol also reported a tractor-trailer was blown onto its side on Interstate 70 about 30 miles east of Kansas City about 1 p.m. No one was injured. The weather service received a report from Plattsburg, Mo., where an anemometer measured 58 mph before it blew away. Golf ball-sized hail was reported at Overland Park, Kan., and Trimble, Mo.
Severe thunderstorm watches covered portions of Iowa, Illinois and Missouri through Sunday night. The primary threats were damaging wind gusts and large hail.
To the southeast, northern Louisiana and Mississippi were bracing for severe storms along with the possibility of flash flooding. The predictions prompted Barksdale Air Force Base near Bossier City, La., to cancel its air show on Sunday. The National Weather Service said northern Alabama could see rain and flash flooding, while central and northern Georgia could see storms and heavy rain.
Sunday was the third anniversary of a 122-tornado day, which struck parts of Mississippi, Alabama, Tennessee, Virginia and Georgia and killed 316 people.
Meanwhile, runners in Oklahoma City took shelter early Sunday as hail and high winds delayed the Oklahoma City Memorial Marathon by 105 minutes to let a severe thunderstorm pass through.

Midwest To Mid-Atlantic Expecting Severe Weather
School districts and authorities are bracing for the possibility of a severe weather outbreak that could bring powerful, long-track tornadoes and large hail Tuesday to the Great Plains.
According to the Storm Prediction Center in Norman, the most dangerous weather will likely take aim at a 70,000-square-mile area stretching from southern Oklahoma to southern Nebraska, including the Oklahoma City area. Heavy winds, tornadoes and hail as large as baseballs or softballs are expected.
In an area stretching from the Rio Grande River in south Texas to Omaha, Nebraska, and the western regions of Missouri, Arkansas and Iowa, nearly 37 million people are at a slight risk or higher of experiencing severe weather Tuesday. In the East, a separate storm system could bring thunderstorms, strong winds and hail to Philadelphia, Baltimore and Washington, D.C. The risk there of severe outbreaks, however, is low.

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
The National Severe Storms Laboratory (NSSL) is a National Oceanic and Atmospheric Administration (NOAA) weather research laboratory under the Office of Oceanic and Atmospheric Research. It is one of seven NOAA Research Laboratories (RLs).NSSL studies weather radar, tornadoes, flash floods, lightning, damaging winds, hail, and winter weather out of Norman, Oklahoma, using various techniques and tools in their HWT, or Hazardous Weather Testbed. NSSL meteorologists developed the first doppler radar for the purpose of meteorological observation, and contributed to the development of the NEXRAD (WSR-88D).
NSSL has a partnership with the Cooperative Institute for Mesoscale Meteorological Studies (CIMMS) at the University of Oklahoma that enables collaboration and participation by students and visiting scientists in performing research. The Lab also works closely with the Storm Prediction Center (SPC) and the National Weather Service Norman Forecast Office, which are co-located at the National Weather Center (NWC) in Norman, Oklahoma. The NWC houses a combination of University of Oklahoma, NOAA and state organizations that work in collaboration.
