...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.
