Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >
On Sunday, May 19th, with an upper level low approaching off the Colorado Front Range through the Panhandles, a fairly stout dry line began to surge eastward off the Texas Caprock and Panhandle reaching as far east as El Reno, OK. With deep layer moisture and favorable wind fields across central Oklahoma, supercell thunderstorms quickly developed along the dry line, primarily along the U.S. Interstate Highway 44 (I-44) corridor, and moved quickly to the east/northeast. As these storms gained intensity, many produced tornadoes, with tornadoes impacting Edmond, Arcadia, Luther and Carney, Norman and Lake Thunderbird, and Shawnee, and two near the town of Prague. The most intense tornado occurred within the city of Shawnee, where EF-4 damage was found as the tornado traveled north of the city before crossing U.S. Interstate Highway 40 (I-40).
Below is a map with the preliminary damage path of the Lake Thunderbird-Bethel Acres-Shawnee tornado. Contours delineate the extent of EF-0 (light blue), EF-1 (green), EF-2 (yellow), EF-3 (orange), and EF-4 (red) damage from the survey.

A long track tornado began at 6:00 PM CDT (5:00 PM CST) in Cleveland County in the eastern sections of Norman just to the north of Lake Thunderbird along 96th Avenue and to the south of Tecumseh Road. The tornado moved northeast, crossing the eastern arm of Lake Thunderbird. A number of homes were significantly damaged as the tornado moved east-northeast through neighborhoods from near Indian Hills Road and 168th Avenue SE to the Pottawatomie County line.
The large tornado moved east-northeast into Pottawatomie County at 6:20 PM CDT and began curving northeast as it approached OK State Highway 102. The tornado moved through the Steelman Estates Mobile Home Park north of Independence Road after crossing OK State Highway 102. Just northeast of the mobile home park, a permanent home was destroyed with much of the debris blown well to the northeast. It continued northeast crossing U.S. Interstate Highway 40 (I-40) near the intersection of US-177, then curved north-northeast finally dissipating near Wolverine Road and Coker Road at 6:50 PM CDT. One fatality occurred in the mobile home park, and another man was killed in his vehicle.
