.SYNOPSIS...
A trough of low pressure will continue cooler than normal weather
through the weekend. High pressure will have greater influence on
the area from the east, leading to near average temperatures by
next week. Breezy west winds will continue this weekend across
mountains and deserts, while the marine layer covers areas west of
the mountains with low clouds each evening into the morning
hours.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
Today through tomorrow...
High pressure conditions dominate the region, although there is
troughing upstream, which has been influencing SOCAL and
providing us with relatively cooler temperatures and below the
seasonal average for this time of year. This will allow for highs
today to be the coolest for the week. Low clouds will begin to
scatter out by later this morning from east to west, and there
could be some of these clouds sticking around along portions of
the coastal areas and periodically going broken throughout the
afternoon. The unseasonably cooler temperatures may also allow for
some record lows for today and tonight. Tomorrow will be slightly
warmer as the trough begins to fill an become absorbed back into
the longwave trough to the north.
Monday through Friday...
By this period in the forecast, there will be a very slow and
gradual amplification and shift in the ridge axis over the desert
southwest, which will begin to edge ever so slightly toward the
region throughout the week and also allow for temperatures to return
to being closer to the seasonal average by the middle of the
week. the marine layer will also begin to thin and lower during
this time. Conditions will remain dry as the monsoonal moisture
plume remains confined far enough east that the mountains and
deserts will remain storm- free through then.
&&
.AVIATION...
260930Z....Coasts/Valleys...Low clouds have filled inland through
about 15-20 miles this morning, with some now stretching into the
southern and western Inland Empire. Bases have lifted to about 2200-
2500ft MSL. 90% chance for CIGs to reach KONT between 10-16z with a
80% chance for KSBD for the same period. These clouds will scatter
back out at 15-16z for inland valleys and eventually 17-18z for the
coast.
Mostly clear skies and VFR conditions prevail through the afternoon
until low clouds redevelop this evening after about 01z Sunday. The
low clouds will have bases around 2000-2500ft, initially favoring San
Diego County when they first develop, but will spread northward into
Orange County by 09z and into inland valleys by 12z.

Sunday morning.
