SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0127 PM CST Thu Dec 25 2025 Valid 271200Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not expected across the U.S. on Saturday or Saturday night. ...Synopsis... Mid-level ridging will continue to deamplify Saturday as a broad Pacific trough ejects over the central CONUS. A positive-tilt lead shortwave will move over the southern/central Plains and into the Midwest Saturday afternoon into early Sunday, while several other perturbations coalesce over the Rockies. A lee low and increasing low-level warm advection/moisture transport should allow for weak elevated destabilization overnight Saturday into early Sunday from the Plains States to the lower OH Valley. Isolated thunderstorms may develop along a stalled frontal zone over KS/OK, spreading east northeastward overnight. Additional storms may form along the lower to middle Texas coast. With only weak buoyancy for elevated thunderstorms and modest deep-layer shear overlap, severe potential appears negligible. ..Lyons.. 12/25/2025
