Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1121 PM CST Wed Feb 22 2023

Valid 241200Z - 251200Z

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

....SUMMARY...
A few low-topped thunderstorms may occur on Friday over parts of
coastal and central California.

....Synopsis...
Strong southwest flow aloft will exist over much of the CONUS on
Friday, with an upper trough over the West and an upper high
centered over FL. The western trough will amplify into Saturday
morning, as an embedded closed low drops south just off the CA
coast. At the surface, high pressure will maintain stable conditions
from the Plains into the East, while a front stalls over the Gulf
coast states. Lift north of this boundary will remain weak, with
generally non-convective rain showers expected.

To the west, cold air aloft may lead to weak instability along the
CA coast, and isolated lightning flashes may occur as a cold front
intersects the coast and translates south during the day.
Instability will be very weak, and therefore severe storms appear
unlikely.
