Area Forecast Discussion
National Weather Service San Diego CA
847 AM PDT Sat Jul 26 2025

.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...

.Morning Update...

Low clouds will continue to retreat off the beaches by later this
morning and into the early afternoon with the northern parts of
the Inland Empire last to clear. Taking a look out our window, we
have a nice array of higher level clouds out there from cirrus to
altocumulus that will continue moving in from the subtropics from
our southwest. Today will feel like the beginning of June instead
of late July as highs will be 5 to 15 degrees below normal thanks
to the low pressure system over Northern California. Inland areas
will warm up a few degrees by Sunday, but overall a wonderful
weekend out there with no major forecast updates the rest of the
week. Enjoy!

.Previous Discussion (250 AM Saturday)...

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.
