SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1123 AM CST Fri Dec 26 2025 Valid 271200Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not expected on Saturday or Saturday night. ...Synopsis... Mid-level ridging over the central US is forecast to weaken as broader troughing over the West begins to move eastward. A positive-tilt lead shortwave will move from the central Rockies over the Plains, into the upper OH Valley Saturday and Saturday night. Lift from this feature will deepen a surface low over the MO Valley allowing for some return moisture and an increase in low-level warm advection Saturday night. Weak elevated buoyancy may develop and support isolated thunderstorms ahead of the trough from eastern KS/OK into the upper OH Valley. Severe potential appears limited owing to MUCAPE generally below 500 J/kg and the potential for any stronger storms to mainly exist beyond 12z Sunday (Day 3). ..Lyons.. 12/26/2025
