Tornado Outbreak Spawns at Least 20 Tornadoes in Four States; Major Damage in Texas

November 17,2015
At least 20 tornadoes have struck a swath of Texas, Oklahoma, Kansas and Nebraska, causing damage in at least two of those states as a severe weather outbreak unfolds across the central and southern Plains. Officials in Texas said one of the tornadoes destroyed an oil and gas facility, raising concerns about radioactive material stored there.

The damaging storms are developing on the warm side of Winter Storm Ajax, which will bring blizzard conditions to the High Plains. 
Here is a roundup of damage reports and other storm-related impacts.

Texas

At least seven tornadoes have struck the Texas Panhandle, including a mile-wide tornado just south of Pampa, Texas.
The storm that spawned the monster tornado first spawned a brief tornado near Groom, Texas, at 6:11 p.m. CST. That tornado apparently dissipated, but a new tornado touched down a short time later and struck areas south and southeast of Pampa. Spotters said it was a mile wide as it passed about 4 miles southeast of the downtown area of Pampa, a city of 18,000 northeast of Amarillo, around 6:40 p.m.
A second tornado touched down near Groom, Texas, shortly before 7 p.m. and while the tornado near Pampa was still on the ground. That tornado struck the south side of Pampa around 7:08 p.m.
The National Weather Service said one of the Pampa tornadoes caused unspecified "major damage" as well as gas leaks and downed power lines on the south side of Pampa. Amarillo television station KAMR said via Twitter that two Gray County Sheriff deputies were sickened by the gas leak.
According to Gray County Emergency Coordinator Sandi Martin, chemical spills and gas leaks are being contained after the Haliburton plant in Pampa was leveled in the storm. No injuries were reported. Officials were also tending to a possible radioactive spill late Monday evening, according to KAMR.
Two thousand people were without power in southeast Amarillo, KAMR also reports. Xcel Energy representative Wes Reeves said there were two transmission lines down in and around the Pampa area. More than 6,500 people were without power in Miami and Canadian, Texas.
A BNSF Railway train was derailed after a major storm in Roberts County, Texas, according to KVII. Officials say the storm pushed the train off its tracks near Miami, Texas. Downed power lines in the area initially prevented emergency crews from reaching the scene of the accident. 
The pair of supercell thunderstorms remained tornadic as they moved northeastward together, passing near Miami and Canadian. Tornadoes were reported near both of those towns. It is not immediately clear whether the tornadoes had stayed on the ground continuously since the Pampa area.
Farther north, a tornado was reported east of Perryton, Texas, at 7:05 p.m. CST. What was likely the same tornado was reported 4 miles west of Booker, Texas, at 7:12 p.m. CST. Subsequent reports placed the tornado 3 miles northwest and then 4 miles north of Booker as it crossed the state line into the Oklahoma Panhandle by 7:24 p.m. Spotters said it was a multiple-vortex tornado during part of that time, and a satellite tornado touched down near the larger tornado at least briefly.
Spotters also reported a tornado near White Deer, Texas, at 6:51 p.m. CST.
Another tornado was reported 12 miles southwest of Wolf Creek Park in the Texas Panhandle at 8:28 p.m. as it crossed U.S. Highway 70.
Yet another tornado was reported 8 miles south of Booker at 9:06 p.m., and was spotted 12 minutes later near Darrouzett before moving northeast into the Oklahoma Panhandle.
Monday afternoon pea-sized hail accumulated on the ground in areas of Cochran and Bailey Counties, according to KTRE. Later that day a storm spotter reported hail covering the ground northeast of Tulia, Texas.

Tornado Reports

Oklahoma

At least three tornadoes affected Oklahoma; two of them moved into the state from Texas.
As noted above, a tornado that touched down in the far northern part of the Texas Panhandle then crossed into the Oklahoma Panhandle shortly before 7:30 p.m. CST south of Elmwood in Beaver County, according to spotter reports relayed by the National Weather Service in Amarillo, Texas.
Another tornado moved into Oklahoma from Texas about two hours later. Spotters saw the tornado 8 miles southwest of Slapout in Beaver County at 9:29 p.m. CST.
Around the same time, spotters reported a tornado 4 miles east of May, Oklahoma, after the pair of storms that had earlier produced tornadoes near Pampa, Texas, merged into a single supercell. There were additional tornado sightings from this cell in Harper County just southwest of Selman, Oklahoma, before it moved into Kansas.

Kansas

At least 11 tornadoes have touched down so far in Kansas, and a 12th moved into the state from Oklahoma, according to our latest analysis of storm reports from the National Weather Service.
According to the NWS, storm chaser observed a tornado south of Ulysses, Kansas, just before 4 p.m. CST. Local schools held their students until the system passed through. 
“The coast is clear and everyone was sent home, safe and sound. District coordinated with local emergency management officials, who determined the severe threat was over,” said superintendent of Ulysses Public Schools Dave Younger. No injuries or substantial damage were reported.
Emergency management reported a tornado 11 miles north of Pierceville in Finney County at 5:19 p.m. CST.
At 5:20 p.m., a small tornado was reported 4 miles southeast of Grinnell in northwest Kansas. Several other reports of tornadoes came from that same cell in the Grainfield and Gove areas of Gove County, along Interstate 70. Those reports may have been a single tornado. The tornado damaged roofs, broke windows, destroyed sheds and downed power lines and trees in the area.
Just before 6 p.m. CST a large tornado was also reported near Kismet, Kansas, and debris was reported in the air near Hayne, Kansas, according to the National Weather Service in Dodge City. A residence and several hog farms were damaged outside of Kismet, where the tornado was estimated at a quarter-mile wide by a storm chaser.
At 6:29 p.m., the National Weather Service said "a large tornado continues and is very well defined from observers" 8 miles north-northwest of Missler, Kansas, from the same cell that produced the tornado near Kismet. It is not immediately clear whether the tornado had been on the ground continuously since hitting the Kismet area.
A tornado struck a rural area 15 miles south of Hoxie in northwest Kansas at 6:43 p.m., downing power lines along Kansas Highway 23. Another tornado was reported by a spotter at 6:44 p.m. just west of Ransom, Kansas. National Weather Service radar detected a tornado debris signature in the area. That tornado knocked down 17 or 18 power poles near Arnold, Kansas, and was later spotted north of Cedar Bluff around 7 p.m.
A tornado was reported near Tasco at 7:06 p.m. CST. Law enforcement officials said the tornado damaged a residence and outbuildings.
In southwest Kansas, a tornado damaged a barn near Montezuma at 6:45 p.m. It may have been the same tornado later blamed for damaging a residence near Howell in Ford County. Between those damage incidents, the twister was spotted by law enforcement just north of Ensign at 7:06 p.m. CST.
At 7:39 p.m. CST, law enforcement and a firefighting unit reported two "rope" tornadoes in rural Hodgeman County about 11 miles east of Kalvesta.
A tornado that was spotted in Harper County, Oklahoma, crossed the state line and damaged two homes in rural Comanche County, Kansas, around 10:20 p.m., according to law enforcement reports relayed by the National Weather Service in Dodge City.
There were numerous reports of quarter-sized hail in western Kansas, as well as a report of golfball-sized hail near Lakin, NWS also reports.
A hog farm and mobile home were destroyed by a tornado in Seward County. A roof was ripped off of a house and a separate garage was damaged in the same area. The families affected were able to take shelter. No injuries were reported. 

Nebraska

The National Weather Service in Hastings said a spotter reported a tornado 5 miles southwest of Stamford in rural Furnas County at 7:51 p.m. CST.
