300 pm pdt Mon mar 18 2019

Synopsis
Conditions will gradually cool through mid week. Some low clouds
and patchy fog will continue to impact the coast. A pacific
trough will arrive Tuesday night and impact the area through
Thursday. This will bring showery conditions to the area, along
with a slight chance of thunderstorms with the most widespread
precipitation occurring late Tuesday night through Wednesday
evening. Gusty southerly winds will occur in the mountains to the
desert slopes. Snow will fall in the mountains and accumulate
above 5500 feet. A much weaker system could bring a few showers in
on Saturday. Tranquil weather will return Sunday through Tuesday
with another storm system possibly arriving by next Wednesday.

Discussion For extreme southwestern california including orange...

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

tranquil weather will prevail across southern california tonight
through Tuesday. Onshore wind flow is taking over and this has
brought in patchy fog to parts of the beaches as a coastal eddy is
developing. This layer is forecast to lift a tad, so widespread
dense fog is not expected tonight. Patchy dense fog will continue
with low stratus likely dominating and spreading into the coastal
valleys overnight.

The next weather systems will arrive Tuesday night. Integrated
vapor transport weakens as this system moves into socal, but this
system will still bring a round of showers to the area beginning
Tuesday night and lasting through Thursday as a closed low moves
towards and possibly over socal by Thursday. The main brunt of
precip looks to occur late Tuesday night through Wednesday when
cape maximizes especially near the coast, but did continue a
slight chance of thunderstorms all areas on Wednesday. MAX hourly
rainfall rates could reach up to 0.40" hr in heavier showers or
isolated tstorms, but not anticipating anything heavier than that.

Scattered showers will continue Wed night-thu then fade thu
evening as the upper low moves to the east.

Rainfall amounts forecast Tue night-Thursday:
coast valleys: 0.25-0.50" most areas
coastal mountain slopes: 0.50-1.00"
deserts: 0.10" or less
snowfall amounts forecast:
5500-6500 ft: 1-4"
6500-7500 ft: 4-6"
7500+ ft: 6"+
an upper level ridge will build weakly in on Friday, then another
storm system will move into central norcal on Saturday. Socal will
just be clipped by this with just a few light showers anticipated
on Saturday with dry weather returning Sunday-Tuesday (march
24-26) as an upper level ridge builds back in. However, gfs
ensembles and ECMWF show the potential of a pacific storm next
wed-thu (march 27-28) with more precipitation possible then.

Aviation
182030z... Coast valleys... Fg will continue along portions of the
immediate coast through this afternoon, with vis 1 2 sm or less at
times. A coastal eddy should help raise ceilings a few hundred feet
tonight, with low clouds bases around 500 ft msl and tops near 1000
ft msl, and push into the coastal valleys by late tonight. Vis will
lower to 1-3 sm br where low clouds near higher terrain, with
isolated areas of 1 2 sm fg. Conditions will improve by mid-tue
morning.

Mountains deserts... Few cumulus this afternoon, then few high
clouds overnight with p6sm vis through Tue morning.

Marine
Areas of fog will continue through tonight, with vis 1 sm or less. A
weak pacific storm will create showers with a slight chance of
thunderstorms, along with an increase in winds and seas Wednesday
through Thursday. Winds and seas may be hazardous at this times
Wednesday and Thursday.

Beaches
A building swell this week will generate surf up to 4-8 feet
Wednesday into Thursday along westerly-facing beaches and strong rip
currents. A high surf advisory may be needed through the period.

Sgx watches warnings advisories

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.
