Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0958 AM CST Sun Dec 31 2023

Valid 311630Z - 011200Z


Thunderstorms are unlikely through early New Year's Day.

Within a split flow regime, a series of southern stream shortwave
troughs will progress eastward from off the southern CA coast to TX.
 A modifying air mass will spread northward over the western Gulf of
Mexico to the TX coast by late tonight, where weak buoyancy will
develop.  However, thermodynamic profiles are not expected to be
particularly favorable for charge separation inland of a weak
coastal trough, with isolated showers/convection expected to remain
too shallow for lightning production.
