Thunderstorms with isolated severe wind gusts will be possible on Thursday across parts of the southern Plains. ...Southern Plains... A positively-tilted mid-level shortwave trough will move northeastward across the southern Plains on Thursday. At the surface, a cold front will advance south-southeastward across Oklahoma and west Texas. Ahead of the front, surface dewpoints from the mid 60s to lower 70s F will contribute to destabilization along a corridor from central Texas north-northeastward into eastern Oklahoma. As surface temperatures warm, isolated to scattered thunderstorms will possible along and near the instability axis in areas where low-level convergence becomes maximized. By mid to late afternoon, steepening low-level lapse rates will make isolated severe wind gusts a possibility. This threat could continue into the early evening as low-level flow increases. Any wind-damage threat that develops is expected to remain marginal. ..Broyles.. 09/30/2026 $$
