Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1052 AM CST Sat Feb 04 2023

Valid 051200Z - 061200Z

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

....SUMMARY...
Severe thunderstorms appear unlikely on Sunday.

....Synopsis...
An upper trough will move across the western states on Sunday,
taking on a positive tilt overnight across the Four Corners states.
Strong cooling aloft will occur north of the midlevel jet max during
the day over northern CA and NV, and heating may lead to weak
instability. Scattered convective showers and a few thunderstorms
are anticipated over coastal northern CA, and from the central
valleys into the Sierra where westerly upslope may aid lift. Severe
weather is unlikely due to weak low-level wind fields, however, cold
air aloft may support graupel.

Elsewhere, rain showers and a few thunderstorms may occur over parts
of the FL Peninsula, where weak lift may develop in association with
an upper trough extending south into the northern Gulf of Mexico.
Mid 60s F dewpoints and heating will lead to weak instability, but
midlevel lapse rates will remain poor, limiting storm strength. The
veering low-level jet will likely focus most of the convection over
the Atlantic Ocean as well.
