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.
