Isolated thunderstorms are possible late Wednesday night/early Thursday morning along coastal southern California. ...Southern CA... A retrograding cutoff low currently near the central/southern CA coast is consistently progged to eject back northeastward as a shortwave trough towards the southern CA coast on Wednesday night. Ahead of this trough, sufficient 850-700 mb moisture within the modest warm conveyor combined with weak mid-level cooling may yield scant elevated buoyancy by the 06-12Z period. This could support a threat of isolated thunderstorms, mainly early morning Thursday. ..Grams.. 12/29/2025
