Synopsis
Strengthening high pressure aloft across california will continue
the warming trend today with the warming continuing in the deserts
Friday. The marine layer will return late tonight with low clouds
and fog, with local dense fog possible, in coastal areas. The marine
layer will deepen through Sunday with low clouds spreading to the
coastal mountain slopes Saturday night. A low pressure system will
move across california late Saturday and early Sunday and will bring
substantial cooling over the weekend and a chance of light showers.

Stronger onshore flow will bring gusty west winds to the mountains
and deserts with strongest winds Saturday afternoon and night. High
pressure will rebuild across california next Monday through
Wednesday and bring a return to fair warm weather.

Discussion For extreme southwestern california including orange...

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

high pressure aloft will peak today and bring warm weather to the
region, including highs in the upper 90s to the lower deserts.

Otherwise, high clouds will continue to drift over. Models indicate
a shallow marine layer developing tonight, with some stratus and fog
near the immediate coast. Local dense fog could form over higher
coastal terrain, such as the mesas. Due to the developing marine
layer, Friday should be a little cooler in coastal areas, though
with 850 mb temps peaking in the deserts then despite the height
falls, the mountains and deserts should have their warmest day of
this week then.

A weak shortwave will move through the region Friday night and help
to deepen the marine layer, then a longwave trough will move through
Saturday night and Sunday. NAM and local WRF both have some light
precipitation, mainly from the valleys to the west mountain slopes,
and given the nocturnal passage of the main vorticity maximum with
the system, I will add some precipitation to the forecast in the
afternoon package. Temperatures will be lower, mostly about 5
degrees below seasonal normals over the weekend. As is typical for
low pressure troughs during the spring, strong gusty winds will
develop over the mountains and deserts, with gusts likely over 50
mph in the usual windy spots, especially Saturday afternoon and
evening. High pressure will rebuild next week and bring fair warmer
weather again, with the possibility of 100 degree temps in the
hottest parts of the lower deserts.

Aviation
181530z... Coast valleys... Sct-bkn high clouds expected today with
bases AOA 20000 ft msl. Better chances for areas of low clouds
returning to coastal areas after 03z fri, with bases 500-1000 ft
msl. Reduced vis of 3 miles or less will be possible due to fog over
higher coastal terrain. Sct conditions expected by 15z Fri at
coastal TAF sites.

Mountains deserts... Mostly clear skies and unrestricted vis expected
through Friday morning.

Marine
No hazardous marine weather through Friday. NW winds 10-15 kt
gusting 20-25 over the outer waters Saturday afternoon into Sunday.

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

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.
