Mesoscale Discussion 0533 NWS Storm Prediction Center Norman OK 0603 PM CDT Sat Apr 25 2026 Areas affected...central Oklahoma into north-central Texas Concerning...Tornado Watch 144... Valid 252303Z - 260030Z The severe weather threat for Tornado Watch 144 continues. SUMMARY...Large to very large hail and tornado threat continues within WW144. DISCUSSION...Two areas of supercell development are noted: one near the Red River southeast of Fredrick, OK and further north near the warm front in Pontotoc County OK. The cell near the warm front in Pontotoc County is in a highly favorable tornado environment, with latest RAP surface objective analysis indicating a broad region of STP 4-5 along and south of the warm front. Given this cells more discrete nature and proximity to the warm front/rich low-level SRH environment, it will pose a greater tornado risk for strong tornadoes in the next 1-2 hours. Further south near the Red River, overall lightning activity has been more appreciable with a pair of splitting supercells (right and left split) with a history of 2 inch hail. The right split has shown signs of strengthening. Given the relatively weaker low-level shear across this region, the greatest potential will remain large to very large hail. However, a tornado (perhaps strong) will continue to be possible given dominate right movement and storm-scale enhancement of low-level SRH. ..Thornton.. 04/25/2026 ...Please see www.spc.noaa.gov for graphic product...
