Synopsis
A deepening trough will bring cooling, with more widespread
marine layer clouds, and breezy conditions in the mountains and
deserts through Friday. Santa ana winds and a building ridge of
high pressure will bring significant warming and drying to the
region Saturday through Tuesday.

Discussion For extreme southwestern california including orange...

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

coastal low clouds are back with a vengeance this morning, having
already filled into the western valleys. Otherwise there were a
few high clouds moving in from the west. Low clouds should clear
inland by mid-morning, but may linger along parts of the coast
through the day.

A long wave trough currently around 500 mi off the pac NW coast
will gradually progress eastward today and Friday, bringing
continued cooling, a deepening marine layer, and breezy conditions
in the mountains and deserts. Another 5-10 degrees of cooling is
expected each day through Friday. As the southern fringes of the
trough axis moves through so cal, the marine layer will be
sufficiently deep to produce some drizzle or light rain from the
coastal mountain slopes westward late Thursday night through
Friday morning.

The weather changes dramatically on Saturday behind the departing
trough. Surface high pressure building over the great basin will
bring another round of offshore flows. Low clouds should be gone
by Saturday morning, and gusty northeast winds will develop
through and below the passes and canyons. Some warming will occur
west of the mountains due to downsloping winds, but cold air
advection from the north will keep temperatures in the mountains
and deserts a few degrees below normal.

For Sunday through Tuesday... An upper level high amplifying over
california will bring significant warming with highs as much as
15-25 degrees above normal Monday and Tuesday. Surface pressure
gradients relax slightly on Sunday for weaker winds, but
strengthen again Monday into Tuesday. Wind gusts of 35 to 50 mph
are possible below the favored passes and canyons in san
bernardino riverside orange counties, and around 25-40 mph along
the coastal slopes and foothills of san diego county. Both the
upper ridge and offshore flow begin to weaken on Wednesday, though
high temps will remain well above normal.

Aviation
190945z... Coast valleys... Low clouds will increase in coverage
through 15z, spreading up to 20 miles inland. Cloud bases are around
1000 ft msl and tops around 1600 ft msl. Reduced visibility of 1 sm
or less is possible near higher terrain. Clearing is expected
between 16z and 18z, with sct clouds AOA 20000 ft msl and light
winds between 18z today and 00z Friday. Low clouds will return to
the coast after 00z Friday, with bases near 2000 ft msl. Forecast
confidence is moderate for timing.

Mountains deserts... Sct clouds AOA 20000 ft msl, unrestricted
visibility, and light winds will continue through 22z. West winds
will increase after 22z, resulting in areas of llws and moderate
up downdrafts over and east of the mtns. Patchy bldu is also
possible in the desert areas. Kpsp and ktrm will see increasing nw
winds after 22z. Forecast confidence is high.

Marine
Northwest winds will increase to 15-25 kt this evening through
Friday, accompanied by combined seas of 5-9 ft. Highest seas and
strongest winds can be expected near and south of san clemente
island. Conditions will slowly improve on Saturday, with light winds
and calmer seas expected early next week.

Beaches
A 2-3 ft 14-16 second south southwest swell will continue to impact
beaches north of solana beach through today. This will produce
elevated surf of 3-5 ft with sets to 6 ft, along with strong rip and
longshore currents. A beach hazard statement remains in effect
through this afternoon. The south southwest swell will diminish
tonight, and be replaced by an elevated short period northwest swell
Friday and Saturday.

Fire weather
Santa ana winds are forecast to develop Saturday through at least
Wednesday, likely peaking Monday and Tuesday. Gusty northeast
winds of 15-25 mph gusting 30-40 mph are possible Saturday, then
weaken slightly for Sunday. For Monday and Tuesday, northeast
winds will be about 15-25 mph with gusts 35-50 mph. High
temperatures 15-25 degrees above normal and offshore flow will
result in daytime humidity at or below 10 percent Sunday through
Tuesday with little to no overnight recovery in the wind prone
areas. This will lead to critical fire weather conditions through
and below the mountain passes and canyons and along the coastal
slopes and foothills Saturday through at least Tuesday, with the
greatest and most widespread threat Monday and Tuesday.

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

Sgx watches warnings advisories
Ca... Beach hazards statement through this evening for orange county
coastal areas-san diego county coastal areas.

Pz... Small craft advisory for winds from 8 pm this evening to 1 am
pdt Saturday for coastal waters from san mateo point to the

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
