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

Forecast Highlights:
*Below average temperatures will prevail for most locations into
 next week.
*Chance of light showers, mainly north of northern San Diego
 County Sunday.
*An unsettled pattern next week will keep cooler, breezy, and cloudy
 conditions with the potential for precipitation at times.

Mostly cloudy skies across much of Southern California this
afternoon, with a few rays of sunshine peaking through at times.
Rainfall has mostly diminished but a few isolated showers are
possible over the San Bernardino mountains into this evening. A
rainfall summary from the rain last night and this morning has
been headlined on our weather.gov/sandiego homepage.

Saturday is expected to be dry and 5 to 10 degrees warmer than
today. Another low pressure system near the Pacific Northwest will
increase onshore flow and bring additional chances of mostly light
precipitation to areas north of northern San Diego county on Sunday.
This system looks like it could squeak out a tenth of an inch or
less for lower elevations and 0.20-0.30 inches for the San
Bernardino mountains and coastal mountain slopes. San Diego County
looks like it will again miss out on most of the precipitation, with
a few locations in coastal north county forecast to get less than a
tenth of an inch.

Global ensemble clusters are in good agreement that a troughy
pattern will prevail over the West Coast early to mid next week.
This will keep conditions cool and unsettled. Temperatures will be
several degrees below average Monday to Thursday. The timing and the
strength of the individual shortwaves rounding the base of the
trough are yet to be resolved, but we could see precipitation if
these features track farther south. Most ECMWF and GFS ensemble
members have some sort of precipitation Tuesday and Wednesday but
there is still a lot of uncertainty surrounding amounts and exact
timing.
