.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...

Evening update...
Marine layer low clouds have redeveloped along the coast with
clear skies elsewhere. The marine layer inversion was based near
1900 ft MSL on the 00Z KNKX sounding, down from about 2300 ft MSL
this morning. A weak trough moving inland across California into
Saturday will help deepen the marine layer with low clouds
spreading into the inland valleys by sunrise Saturday. Otherwise
breezy west winds will continue in the mountains and deserts through
late tonight, then strengthening again Saturday afternoon and
evening. Wind gusts will generally be around 25-35 mph, locally
around 50 mph through the San Gorgonio Pass. High temperatures
Saturday will be as much as 10-15 degrees below normal away from
the coast, and around 4-7 degrees below normal near the coast.
Even the inland valleys will barely reach the mid 80s. Only other
thing to note this evening is that ensembles have dried out for
the middle to latter part of next week, with only a few members of
each global ensemble showing an uptick in precipitable water. At
this point chances of monsoon moisture returning are extremely
minimal with southwest flow aloft dominating the pattern.

Previous discussion...
The low will weaken and combine with the mean flow aloft by
Sunday and Monday as a large area of low pressure moves closer to
the Pacific Northwest. As this occurs, high pressure over the
Southern Plains of Texas will expand westward into the Desert
Southwest. This will bring a warming trend to our region by the
early part of next week. By Tuesday into the latter part of next
week, temperatures will plateau near average across the region.
Widespread 90s will return to the Inland Empire/High Desert, near
110 degrees in the lower deserts, with 70s/80s for the mountains,
coastal valleys and beaches. Ensemble models show the weak
troughing pattern continuing into later next week keeping
temperatures near normal. Model differences become more apparent
by the following weekend, some showing higher pressure moving into
the area which would lead to a slow warming trend.

inland valleys. Low clouds to scatter out Saturday 15-18Z. Low
clouds Saturday evening should develop a little later (after 04Z)
