Valid 031630Z - 041200Z


Isolated thunderstorms are possible this afternoon over parts of
Florida and near-coastal southern California, and tonight over
northern Arizona.

A weak cold front continues to sag southward across the FL
peninsula, accompanied by a line of showers.  Sufficient CAPE is
present to support occasional lightning flashes with this activity,
but none have been recently noted and the overall threat is
diminishing rapidly.

...Southern CA...
A progressive upper low is approaching the coast of southern CA,
with a cluster of showers and isolated thunderstorms noted off the
coast of San Diego and Orange counties.  As this activity moves
inland this afternoon, a few lightning flashes are possible.  

...Northern AZ tonight...
As the aforementioned upper low moves inland tonight, strengthening
low-level warm advection and lift will promote the develop of a few
thunderstorms across northern AZ.  No severe storms are expected.
