Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1149 PM CDT Sun Mar 09 2025
Valid 111200Z - 121200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are possible across far southwest California
Tuesday afternoon/evening. Severe storms are not expected.
...Synopsis...
Generally low-amplitude westerly mid/upper flow will overspread the
Plains and Southeast ahead of a shortwave upper trough moving into
the Southwest. At the surface, a prior cold frontal passage deep
into the Gulf and high pressure over the eastern Gulf/Southeast will
result in a dearth of boundary layer moisture east of the Rockies
for much of the period. Further west, a surface low offshore
southern CA will weaken as it moves east over southern CA during the
afternoon/evening. Cool temperatures aloft beneath the upper trough
will support steep lapse rates and weak instability (MUCAPE
generally less than 300 J/kg). Isolated thunderstorms will be
possible offshore and may persist inland across a small part of
southwest CA.
