Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1138 AM CDT Mon Mar 20 2023

Valid 211200Z - 221200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Tuesday.

....Synopsis...
On Tuesday, an upper low will move into central CA with a strong
cyclonically-curved midlevel jet nosing into AZ and UT by 12Z
Wednesday. Generally zonal flow conditions will prevail across the
central and eastern states with high pressure over the East. Cold
air aloft across the West will lead to areas of daytime
thunderstorms from central and southern CA into the Great Basin.
Weak instability is expected to preclude any severe storm threat.

While the primary surface low will affect central CA and NV, a
secondary low will develop over KS, with increasing low-level
moisture return occurring from TX into OK. A leading/weaker wave and
associated low-level jet will aid scattered elevated thunderstorms
mainly from eastern KS into MO, but instability will be too weak for
severe storms. Otherwise, the remainder of the warm sector across
the southern Plains is to remain stable due to temporary warming
aloft.
