....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated thunderstorms are possible across parts of central and
southern California on Friday.

....Discussion...
As a mid-level trough departs the East Coast early Friday, a
clipper-type system will advance quickly east-southeastward across
the Great Lakes, reinforcing eastern U.S. cyclonic flow.  In the
West, a disturbance over the Desert Southwest is progged to shift
eastward with time, downstream of a much strong upper cyclone
approaching -- and eventually reaching -- the southern half of
California.

As the upper low gradually moves inland, cold air/steep lase rates
aloft will support an increase in shower convection.  A few
low-topped thunderstorms will be possible overnight, and thus will
maintain 10% thunder potential, though with somewhat of a northward
areal shift from the prior forecast.
