ACUS11 KWNS 242230 SWOMCD SPC MCD 242230 ARZ000-LAZ000-TXZ000-OKZ000-250100- Mesoscale Discussion 0521 NWS Storm Prediction Center Norman OK 0530 PM CDT Fri Apr 24 2026 Areas affected...from southeast Oklahoma into the ArkLaTex area Concerning...Tornado Watch 141... Valid 242230Z - 250100Z The severe weather threat for Tornado Watch 141 continues. SUMMARY...A narrow corridor of tornado risk is evident over southeast Oklahoma, with threat expanding southeastward toward the ArkLaTex this evening. Damaging winds and hail will also be likely. DISCUSSION...Severe storms persist near the synoptic cold front from south of Ft. Smith into southeast OK. Intersecting this front is an outflow boundary which is pushing west/southwest out of AR and into northeast TX and northern LA. This same boundary appears to be hanging up over southeast OK ahead of the severe storms. The tornadic supercell over southern Pittsburg County is moving toward Pushmataha County, which is near the intersecting boundaries. Low-level shear in this area, as well as into northeast TX/southwest AR is sufficient to support tornadoes with 0-1 SRH over 100 m2/s2. The air mass is very moist and unstable, with deep-layer shear around 50 kt aiding storm longevity. As such, these cells may continue to pose a tornado risk as they interact with the outflow boundary to the southeast. Other cells to the west may contain hail and damaging winds, with cells north of the outflow also producing hail into AR. ..Jewell.. 04/24/2026 ...Please see www.spc.noaa.gov for graphic product...
