Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0226 AM CDT Mon Mar 13 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
CONUS should advance across southern CA, the Great Basin, and the
Southwest on Wednesday. Even though low-level moisture is expected
to remain rather limited, sufficient elevated instability will
probably develop through the day as mid-level temperatures cool and
lapse rates gradually steepen. Isolated convection capable of
producing occasional lightning flashes may occur across these
regions as the southern-stream shortwave trough moves eastward.

Low-level moisture return will likely occur across the southern
Plains through Wednesday night as the upper trough approaches and a
southerly low-level jet strengthens. This moisture will initially
remain quite limited, with a substantial cap also forecast. The
potential for elevated thunderstorms in this warm advection regime
will probably remain low until perhaps late Wednesday night and
early Thursday morning (after 16/06Z). Even if any thunderstorms
form, MUCAPE should remain too weak to support a threat for large
hail through the end of the period.
