Mesoscale Discussion 0491 NWS Storm Prediction Center Norman OK 0901 PM CDT Sat Apr 19 2025 Areas affected...portions of extreme north Texas into southern Oklahoma Concerning...Tornado Watch 149... Valid 200201Z - 200330Z The severe weather threat for Tornado Watch 149 continues. SUMMARY...The tornado threat should continue with ongoing storms along the Red River into southern OK over the next few hours. DISCUSSION...Several strong to severe thunderstorms are growing upscale into an MCS along the Red River, and these storms are poised to advance east-northeast across southern OK over the next few hours. An embedded, sustained supercell has recently produced a tornado in Love County, OK, and tornado potential is expected to continue with this storm, even if it morphs into a bowing/LEWP structure. Regional VADs depict large, curved hodographs across central TX/OK, and adequate surface based buoyancy remains in place. Furthermore, the 01Z Warn-on-Forecast run depicts continued swaths of stronger 0-2 km updraft helicity, indicative of longer-term low-level rotation potential with the ongoing storms. Given the strong low-level shear in place, a strong tornado remains possible. ..Squitieri.. 04/20/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...TSA...FWD...OUN...
