A trough along the west coast will result in cooler than average
temperatures through Saturday along with a deeper marine layer.
A ridge will build into Southern California early next week,
leading to warmer conditions. No rain is in the forecast as
monsoonal moisture looks to keep its distance from the area
through next week.



Tranquil weather will be the rule through next week across
Southern California. Monsoonal moisture looks to remain off to our
east through next week, though will have to see if some of it may
sneak into our deserts ahead of the next trough moving in during
the middle part of next week. Right now the thinking is no rain
for the foreseeable future.

A trough over the west coast of the U.S. will be the dominant
weather feature through Saturday. This will result in temps
running below average and a deeper marine layer with
nighttime/morning low clouds spreading further inland.

A ridge will build into the area early next week. GFS continues
stronger with the ridge compared to the ECMWF, but has lessened
its strength a tad. Excessive heat is not anticipated. Have used
a blended approach for temps during this period. Yet another
trough is poised to move in during the middle and latter part of
next week per model consensus. This will result in a cooling trend
for the 2nd half of next week after a hotter early part of the


250900Z...Low clouds will continue to develop along the coast and
into far western valleys, but not into inland valleys this morning.
Bases will be around 1200 feet msl with tops to 1600 feet. Local vis
3-5sm along inland extent of clouds. Clearing is expected by 16Z
this morning. Low clouds will return this evening to coastal
airports between 03-07Z with bases closer to 1500 feet msl. Outside
the marine layer, skies will be mostly clear today and tonight.


No hazardous marine weather is expected through Monday.


Skywarn activation will not be needed today.
