Tornado Report Description: On 31 May, an intense, long-track tornado formed southwest of El Reno. This exceptionally wide tornado took a complex path, rapidly changing in both speed and direction. The tornado spared El Reno and its airport from a direct hit, tracking just south of those locations. The tornado damaged numerous homes along with a few businesses near El Reno. Additionally, intense sub-vortices destroyed crops in numerous fields in the area.||The tornado developed at 6:03 p.m. just northeast of the intersection of Heaston and Reuter roads. Initially, the tornado moved to the southeast at 20 to 25 mph. At 6:09 p.m., the tornado turned to the east, just south of Reno Road between Heaston and Brandley roads. The tornado continued to expand in size just southwest of the El Reno Municipal Air Park, where its speed increased to 30 to 40 mph. As the tornado passed just south of the airport, two satellite tornadoes formed briefly on the west side of the tornado.||At 6:19 p.m. the tornado crossed Highway 81 near Reno Road as it continued to expand in size. There, the tornado abruptly turned to the north, while also accelerating to greater than 50 mph. From 6:24 to 6:26 p.m., the tornado reached its maximum in size and intensity near the intersection of Radio and Reuter roads. The tornado, still very large, slowed down as it approached I-40. From 6:27 to 6:35 the tornado made a loop just north of the interstate while decelerating to less than 10 mph. After 6:35, the tornado moved east once again, and dissipated at 6:42 p.m. near the intersection of I-40 and Banner Road.| |Eight people were killed in the tornado, all in vehicles. This included three severe storm researchers who were killed east of US-81 as the tornado overtook their position. Additionally, several other people were killed while attempting to escape the tornado near Highway 81. Finally, two people were killed along I-40 while waiting for the storm to pass.||The monetary damages were estimated. This tornado was well sampled by two separate mobile research radar teams ��� the University of Oklahoma RaXPol radar, and the Center for Severe Weather Research���s Doppler on Wheels. Both radars captured high temporal and spatial resolution data relatively close to the large tornado. Both radars measured winds in the tornado of more than 200 mph. The RaXPol radar data shows winds of at least 295 mph very close to the surface. These intense winds were present in very small sub-vortices within the larger tornado circulation. An analysis of the high resolution radar data combined with the results of the ground damage survey indicates that none of these intense sub-vortices impacted any structures in rural Canadian County. So despite the measured wind speeds, surveyors could not find any damage that would support a rating higher than EF3 based solely on the damage indicators used with the EF scale. ||The maximum tornado width was 2.6 miles. However, the damaging wind swath was much larger, as non-tornadic downdraft winds extended for at least a mile south of the tornado. Given the difficulty of separating this damage from tornadic damage, the OU RaXPol radar was used to help determine the width.

Tornado Report Description: Storm damage survey and Spotter Network reports confirmed a brief tornado in rural areas south of Calumet. Convergent wheat pattern and minor tree damage were noted.

Tornado Report Description: A tornado touched down briefly about 6 miles west of Calumet destroying a barn and damaging a house. Damage was estimated.

Tornado Report Description: This tornado is labeled Tornado B2 (Segment #1 of the Calumet-El Reno-Piedmont-Guthrie tornado). This tornado began very close to the Caddo/Canadian county border and quickly became a strong/violent tornado. The tornado destroyed numerous trees, many of them were debarked, before crossing Interstate 40. Three people died in vehicles near the I-40 Calumet exit, and two other fatalities occurred just northeast of that location. Cars were thrown thousands of feet off the roadways. It is believed that the tornado reached its maximum intensity just after crossing I-40, and it was here that a mobile radar measured winds of greater than 210 mph just off the surface. The El Reno Oklahoma Mesonet station (5 miles west) measured wind gusts of 131 and 151 mph. From this location, the tornado continued northeast, narrowly missing the town of Piedmont. Widespread EF-3, occasional EF-4 damage occurred between El Reno and Piedmont. More widespread EF-4 damage was seen west and north of Piedmont. Especially hard hit was the Falcon Lake neighborhood, near the Kingfisher county border. Two children were killed at this location. The tornado continued into southeastern Kingfisher County. Monetary damage estimates were not available at this time, but were probably going to be well in the tens of millions.

Tornado Report Description: This tornado, also anti-cyclonic, formed about 1 mile NW of the previous tornado (4.5 ENE Calumet) shortly after the latter dissipated. It touched down intermittently as it moved ESE, lifting 4 miles NW of Concho at 1920 after forming a very brief, needle-like condensation funnel seen by spotters and caught on video by local media (KWTV Ch. 9). Damage was reported by spotters at a location 3 miles north and 4 miles east of Calumet.

Tornado Report Description: This anti-cyclonic tornado formed from a new lowering that first developed WNW of Calumet. Unlike the earlier tornadoes, this one was not wrapped in rain and was documented visually by numerous spotters as well as the Doppler On Wheels (DOW). The tornadic circulation first formed at 1902 about 2 miles NNW of Calumet, based on DOW data, but spotters observed only a funnel cloud until debris was observed at 1904, 2 miles north of Calumet. The tornado tracked generally east near EW95 Road, with occasional jogs to the NE and SE. It ended 4-5 miles NE of Calumet at 1914 CST. This tornado was visible mainly as a debris cloud on the ground; the condensation funnel reached the ground only briefly at 1904 and again at 1910, otherwise it either remained aloft or was non-existent. The tornado had multiple vortices briefly.Two permanent homes received damage. One home towards the beginning of the tornado sustained minor roof damage with shingles blown off. Another home had an enclosure, that was built over the pool, destroyed. A nearby manufactured home also showed damage to its siding, roof, and windows. Damage was estimated at low end to middle F1.

Tornado Report Description: The tornado, 2.5 N of Geary in Blaine county, crossed into Canadian County at 1838 CST. Damage remained confined to the right side of the track of the circulation center. The tornado and the parent mesocyclone then turned to the NE, inflicting F1 and low-F2 damage to several rural homes northeast of Geary. Seven miles NE of Geary, the center turned back to the E at 1852, paralleling 220th Street (EW91 Road) for about 2 miles. It then turned to the NE at 1902 and eventually to the N by 1908. The tornado was wrapped in rain during its entire latter stages, and therefore was not visible. Doppler on Wheels (DOW) data indicate that the tornadic circulation crossed into Kingfisher County 11 miles west of Okarche.One farmstead, approximately 5-6 miles northeast of Geary, received heavy damage with the 100 year old farmhouse sustaining substantial damage and several outbuildings and barns destroyed.

Tornado Report Description: This short-lived tornado was observed by an off-duty National Weather Service meteorologist near mile marker 117 on Interstate 40 in Canadian County. A motorhome was blown over, and a highway sign was ripped off its post, consistent with an F0 rating.
