Synopsis
The strong high pressure ridge over the eastern pacific will
remain in place through next week. A disturbance will drop south
along the eastern side of the ridge on Saturday, briefly drawing
moist, marine air back over the region and setting up a cooler
weekend. As it passes to the southeast, the dry offshore winds will
return on Sunday. Not quite as warm next week, but continued fair
and dry with above average temperatures.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

at 1 pm pst, water vapor satellite imagery displayed an upper-
level ridge off the west coast nudging into southern california,
and an upper-level trough off the pacific northwest. The highest
wind gust this morning was 69 mph at sill hill. Check out our
highest wind gust summary headlined on our webpage. Winds will
continue to diminish through the afternoon as offshore pressure
gradients weaken. Highs 5-15 degrees above normal will continue
today with ridging aloft.

The aforementioned trough will quickly swing across southern
california Saturday, which will help lower high temperatures to near
seasonal normals, return onshore, westerly flow across most of the
area and somewhat increase humidity. Instability and moisture
may be sufficient enough to generate a shower or two over the
coastal waters. Once the trough moves to our south, northerly flow
will set up across the region. This, along with building high
pressure over the great basin, will create yet another round of
gusty santa ana winds across portions of san bernardino, riverside
and orange counties Saturday night through Sunday. Due to the
direction of the winds, san diego county should avoid the higher
gusts. North to northeast winds of 20-30 mph, with gusts to 55
mph are possible along coastal mountain slopes, canyons and
through the cajon pass. Isolated gusts could reach near 70 mph in
the usual windiest locations. Mountain waves are possible, and
could help gusty winds surface over portions of the inland empire
and coastal orange county. Winds will diminish overnight Sunday
night, but remain weak and offshore through Tuesday. A cold
airmass will help low temperatures dip into the 20s for a good
portion of the high desert Sunday and Monday mornings.

The upper-level ridge will remain strong and anchored to our west
through next week, which will allow for another trough to swing
across the great basin. This will help switch our flow back to
onshore and westerly on Wednesday, but then could generate another
round of santa ana winds late Thursday through Friday once it
exits the region. Highs will remain above seasonal normals next
week, but not be as high as they have been this week.

Unfortunately, no sign of precipitation is on our horizon for the
next week.

Aviation
152000z... Mostly skc with p6sm vis through 16 0900 utc. 16 0900-
1800 utc, patchy stratus with bases 1000-2000 ft msl and tops to
2500 ft msl developing at the coast and possibly spreading into the
valleys.

Marine
No hazardous marine weather is expected through Wednesday.

Fire weather
Westerly winds will develop across most areas Saturday, along with
higher relative humidity, as an upper-level trough moves across
the region.

Gusty northeasterly winds will redevelop late Saturday night
through Sunday evening across portions of san bernardino,
riverside and orange counties, with low relative humidity pushing
in Sunday morning. Gusts around 55 mph are expected in the usual
windy locations with possible isolated gusts near 70 mph. A red
flag warning has been issued for 8 am through 8 pm Sunday for
those locations. San diego county may not see as strong of winds
or very low humidity with this event, however there is still time
for them to increase over the next day or so for Sunday.

Therefore, san diego valleys and mountains remain in a fire
weather watch from 8 am to 8 pm Sunday.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.
