DISCUSSION:

A compact storm near Catalina Island will bring showers and isolated
TSTMs to LA county today with the peak of activity in the morning.
Most of the SE portion of LA County will see an additional third to
two thirds of an inch of rain with local amounts over an inch in
locations where heavier cells pass over. Ventura county will see
much less rainfall and SLO/SBA counties will see little if any
rainfall. Rainfall rates could rfeach 1 inch per hour under heavy
showers or TSTMs this morning in LA County. Snow levels have dropped
to as low as 4,000 feet. Snow amounts of 3 to 6 inches is the most
likely outcome for elevations above 6,000 feet with 1 to 3 inched
possible from 4000-6000 ft.

Dry weather will likely follow this weekend through at least most of
next week.
