Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1002 AM CST Sat Dec 30 2023

Valid 301630Z - 311200Z


Thunderstorm potential appears low through tonight.

A mid/upper-level shortwave trough is moving eastward across
central/southern CA this morning. An extensive precipitation band
associated with this shortwave is expected to weaken later this
morning, as stronger ascent becomes increasingly displaced eastward
of available moisture. In the wake of the early-morning
precipitation, showers may develop across near-coastal regions of
central/southern CA by midday into early afternoon. However, with
instability expected to remain quite weak and convection likely to
be rather shallow and low-topped, lightning potential appears low.  

Elsewhere, persistent dry/stable conditions will limit thunderstorm
potential across the rest of the CONUS.
