SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0630 PM CST Tue Jan 27 2026 Valid 280100Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms may occur through tonight across parts of northern California and coastal southwest Oregon. Severe thunderstorms are not forecast. ...Discussion... An upper trough will quickly move across northern CA and parts of the Pacific Northwest through tonight, with a weakening trend. Despite this, increasing lift, cooling aloft and a midlevel moist plume may support weak SBCAPE near the coast and elevated instability inland. The weak instability and minimal wind speeds below 700 mb should preclude any severe risk. Elsewhere, cool and stable conditions will prevail with an expansive upper trough east of the Rockies and high pressure. ..Jewell.. 01/28/2026
