559 ACUS48 KWNS 140808 SWOD48 SPC AC 140807 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0207 AM CST Fri Nov 14 2025 Valid 171200Z - 221200Z ...DISCUSSION... A midlevel shortwave trough will dampen as it shifts east from the central Plains toward the Mid-South in the Day 4-5/Mon-Tue time period. Some enhanced westerly flow will overspread the region nonetheless, and a weak surface low is forecast to track from KS/OK toward the central or southern Appalachians through Tuesday night. Ahead of the surface low and an attending cold front, modest Gulf moisture return is forecast across the southern Plains into the Lower MS Valley. Some strong to isolated severe thunderstorms could develop across the Ozarks to the Mid-South vicinity Monday and Tuesday, through confidence in 15 percent coverage is low given the weakening midlevel trough and lack of a deepening surface cyclone. During the Day 6-8 period, forecast model spread increases considerably. However, a general trend indicating a deepening trough across the West ejecting across the Plains toward the central U.S. Thursday and Friday is apparent. Depending on the evolution of this feature and any developing surface cyclone and attendant Gulf return flow across the south-central U.S., an increase in severe thunderstorm potential could develop. Large spread and poor run-to-run consistency among various guidance precludes probabilities at this time. ..Leitman.. 11/14/2025
