SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0215 AM CST Fri Jan 02 2026 Valid 041200Z - 051200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Sunday or Sunday night. ...West Coast to the CA Central Valley... Latest guidance remains reasonably consistent with the evolution of the persistent eastern Pacific upper trough on Sunday. One embedded shortwave impulse should impinge on western WA early Sunday, while a separate impulse shifts inland across southern CA through Sunday night. Guidance is also highly consistent in depicting minimal buoyancy in vicinity of these impulses, likely yielding lower- probability thunder potential compared to D2/Saturday. Sporadic/very isolated lightning coverage will probably diurnally peak on Sunday afternoon, where cold mid-level temperatures are present along most of the West Coast into the Central Valley. ..Grams.. 01/02/2026
