Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1234 AM CDT Tue Mar 14 2023
Valid 151200Z - 161200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast on Wednesday.
...Synopsis and Discussion...
The southern portion of a large-scale upper trough over the western
states will move eastward across southern CA, the Great Basin, and
the Southwest on Wednesday. Even though low-level moisture will
remain limited, weak MUCAPE should develop through the day as
mid-level temperatures cool and lapse rates aloft gradually steepen.
Isolated convection capable of producing occasional lightning
flashes may occur as ascent associated with the southern-stream
shortwave trough overspreads these areas. This activity is expected
to generally remain elevated.
Low-level moisture return will occur across the southern Plains
through Wednesday night as the shortwave trough approaches and a
southerly low-level jet strengthens. This moisture will initially be
fairly limited, with a substantial cap also forecast. The potential
for elevated thunderstorms in the low-level warm advection regime
should remain low until perhaps late Wednesday night and early
Thursday morning (after 16/06Z), as the cap gradually erodes. Even
if any thunderstorms form, MUCAPE should remain too weak to support
a threat for severe hail through the end of the Day 2 period.
