Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1052 PM CST Sun Jan 11 2026
Valid 121200Z - 131200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected today and tonight.
...Synopsis...
Surface high pressure will be in place from the Intermountain West
to the Southeast today. The expansive high pressure extending from
the southern Plains to the Southeast will maintain continental
trajectories and offshore flow, cutting off Gulf moisture. The lack
of boundary layer moisture, and cool/stable conditions will preclude
thunderstorm activity through Monday night/early Tuesday.
