.SYNOPSIS...
Cool and cloudy weather will continue through today, with isolated light
showers bringing periods of rain and mountain snow. There will also
be gusty southwest to west winds in the mountain passes and
adjacent desert areas, weakening this evening. Fair and warmer
weather will follow for most of next week, with the usual marine
layer low clouds during the nights and mornings. Temperatures will
then cool off again as we approach next weekend.

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

This morning...Isolated light showers continue across the region, bringing
localized small accumulations through this evening. The closed upper
low is now over NV with a series of weak disturbances rotating around
it. High-resolution models indicate that these disturbances will continue
to trigger isolated showers through this evening. Additional accumulations
will range from a trace in the coastal areas to about two tenths on
the coastal mtn slopes. A dusting to about 1 inch of additional snow
is expected above 5,500 ft. Locally gusty winds will continue
through this evening in the mountain passes and adjacent desert
areas where gusts of 35-45 mph will be possible.

A warming trend will begin on Monday and continue through the
work-week even though low pressure will continue to dominate the
pattern over southern California. After the current low pressure
system moves into the Rockies on Tuesday, a weak ridge of high
pressure will transit the region on Wednesday immediately followed
by another weaker low pressure system. Temperatures will rise into
the 60s and 70s for areas west of the mountains but will still be
near or slightly below seasonal averages. A persistent, deep
marine layer will bring low clouds to the coastal areas and
valleys during the nights and mornings, with day-to-day variations
in coverage.

For next weekend, a growing number of solutions are indicating the
potential for another round of windy conditions and showers along
with lower temperatures as another strong low pressure system
moves in from the northwest. There is still significant spread
among the ensemble members so confidence in the details remains
relatively low.

through the desert mountain slopes and locally into the deserts,
including below mountain passes. SCT -SHRA/-SHSN will occur in the
