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 >
An active week of severe weather continued during the afternoon and evening of May 4, 2022. Ahead of a west Texas dryline, a few supercell thunderstorms developed across western Oklahoma and north Texas. Additional supercell thunderstorms developed in the vicinity of a warm front across east-central Oklahoma. Multiple tornadoes along with scattered large hail and wind damage events occurred within the WFO Norman warning area. The most significant storm of the event developed in Dickens County, Texas (NWS Lubbock warning area) and traveled across portions of west north Texas (King, Foard and Wilbarger counties). Storm survey teams confirmed that this storm produced two long-track tornadoes in the NWS Norman area, including a long-track EF-3 tornado that struck the town of Lockett, TX just after sunset.
Another significant supercell occurred further east across central Oklahoma, itself producing a long-track significant (EF-2) tornado. This tornado impacted downtown Seminole, OK at a width around one half mile. Widespread areas of light to moderate damage occurred throughout town. This storm went on to produce an additional long-track tornado from near Cromwell to Okemah, OK (NWS Tulsa warning area). Another supercell storm, immediately trailing the "Seminole" tornadic storm, produced additional tornadoes across Pottawatomie and Seminole counties. One tornado produced from this storm completed a near full loop near the town of Earlsboro, OK.
In addition, areas of very heavy rainfall fell across portions of central Oklahoma, generally along and east of the I-35 corridor. Heaviest amounts (around 2-4 inches) occurred across portions of northern Pottawatomie and Seminole counties, where multiple thunderstorms trained across similar areas into the early morning of May 5th.

intense damage occurred along Ew1250 road east of Ns3510 Rd where
numerous Oak trees were snapped and uprooted with large limbs
blown downwind. A house in the vicinity lost several courses of
shingles. We applied a higher than expected wind speed to the
house given higher than typical quality of the shingles. An
outhouse near the residence was leveled and debris blown
downwind. Farther east on Ns3550 Rd, a small stretch of trees
exhibited the most intense damage with roughly 50% of them
uprooted or snapped. Finally, the last tree damage occurred one
