Synopsis
A low pressure system from the north will bring cooling today,
strong and gusty west winds for the mountains and deserts into
tonight, and occasional showers along and west of the mountains
with the snow level lowering to 5500 to 6000 feet for late tonight
into Monday morning. For late Monday into next weekend, low
pressure will weaken across southern california with a gradual
warming trend which will return high temperatures to near average
by next weekend.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

early this morning, a closed upper level low pressure system is
centered near the northern california coast. The center is
expected to be nearing las vegas in 24 hours, then moving to
southeastern utah by late Monday afternoon. This track is slightly
to the north of the forecast track from 24 hours ago. Satellite
imagery shows widespread coastal low clouds extending inland and
onto the coastal mountain slopes.

Higher resolution models continue to show an initial band of
light showers developing near the coast and moving inland along
the orange county coast after daybreak and inland along the san
diego county coast after 8 am, reaching the mountains by around
noon. This is slightly slower than the forecast from 24 hours ago.

The showers will linger near the mountains and inland valleys
through the afternoon. Another area of more widespread showers
will spread inland during the late afternoon and evening. Showers
will decrease from the northwest late tonight into Monday morning.

Rainfall is expected to range from around two tenths of an inch
near the coast to one half to one inch in the mountains, except
locally to two inches on the south slopes of the san bernardino
county mountains. The snow level will mostly be 6500 to 7000 feet
today, then fall to around 5500 feet tonight. Snowfall of one to
two inches is possible above 6000 feet with local amounts around 6
inches above 7500 feet.

This low pressure system will also strengthen the onshore flow
bringing periods of strong and gusty west winds in the mountains
and deserts into tonight with strongest gusts to around 65 mph for
this afternoon and evening. High temperatures will also be cooler
today, a few degrees cooler near the coast, and 10 to 15 degrees
cooler in the mountains, deserts, and inland valleys. This will be
more than 20 degrees below average for the mountains, deserts, and
inland valleys.

Residual showers are expected to end from the northwest Monday
morning with high temperatures around 5 degrees warmer than today,
but still well below average.

For Tuesday into next weekend, there remain differences in the
details of low pressure troughing over the southwest states. In
general, the trend is for weakening of the low pressure with a
slow warming trend into next weekend which will warm high
temperatures to near average for next weekend.
