...NO SEVERE THUNDERSTORM AREAS FORECAST...



...SUMMARY...

Isolated thunderstorms are possible during the early morning of New

Year's Day along coastal southern California.



...Coastal southern CA...

An initially slow-moving upper low is forecast to eject

northeastward as a shortwave trough and approach coastal southern CA

by the end of the period. The primary midlevel cold core is forecast

to still be offshore at the end of the period (12Z Thursday).

However, some moistening beneath modest cooling aloft could support

isolated thunderstorm potential late in the period across the

Channel Islands and eventually coastal areas of southern CA. Some

enlargement of low-level hodographs is expected as this system

approaches, but with scant buoyancy and only modest effective shear,

organized severe potential appears low.
