Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1138 PM CST Sun Jan 26 2025

Valid 271200Z - 281200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Lingering isolated thunderstorms are likely this morning across the
lower Mississippi River Valley with more persistent, though still
isolated, thunderstorms chances across southern California into
portions of the lower Colorado Valley. Severe weather potential
remains quite low.

...Synopsis...
A broad upper-level trough remains in place from the Great Lakes
region through the Southwest with a more pronounced upper low just
off the southern CA coast based on late-evening water vapor imagery
and 00 UTC RAOBs. This synoptic regime is expected to largely remain
in place for today as the trough slowly migrates southeast. At the
surface, a frontolytic cold front extending from the upper OH River
Valley into the lower MS River Valley and TX Gulf Coast will
continue to push east/southeast, resulting in largely offshore flow
along much of the central Gulf Coast by late this afternoon. Before
this occurs, weak ascent along the boundary, coupled with very
modest - but sufficient - buoyancy ahead of the front (sampled best
by the 00 UTC LCH sounding), should support isolated thunderstorms
from the start of the period (12 UTC) through around 16-18 UTC.
Further west, cold temperatures aloft associated with the core of
the upper low will overspread the lower CO Valley through the day. A
modest influx of Pacific moisture coupled with steepening lapse
rates and weak ascent will promote sporadic thunderstorm development
through much of the day and possibly into the overnight hours.
