Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0655 AM CST Thu Dec 21 2023

Valid 211300Z - 221200Z


Isolated thunderstorms are possible today across parts of southern
California, southern Arizona and from north Texas into southeast
Kansas. Severe thunderstorms are not expected.

An eastern Pacific upper-level low, to the southwest of California,
will move eastward today towards the northwestern coast of Baja
California. Isolated thunderstorms, aided by large-scale ascent and
steep mid-level lapse rates, will be possible across parts of
southern California, along the northern periphery of the system.

Further east into the southern and central Plains, a shortwave
trough will move eastward through the region. Moisture advection
will take place ahead of the shortwave trough across the southern
Plains, as a surface low deepens in the northwestern Texas
Panhandle. As weak instability develops near the moist axis,
isolated thunderstorms will be possible late this afternoon from
north Texas into southeast Kansas.

No severe threat is expected across the continental United States
today or tonight.
