area forecast discussion
national weather service san diego ca
930 pm pdt Mon mar 18 2019

Synopsis
A cooling trend will occur through mid week as high pressure aloft
shifts to the east and a pacific trough approaches from the
northwest. Some low clouds and patchy dense fog will occur
overnight near the coast. A pacific trough will arrive late 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 Wednesday through
Wednesday evening. Gusty southwesterly winds will occur in the
mountains to the desert slopes. Snow will fall in the mountains and
above 5500 feet. A much weaker system could bring a few showers
Saturday. Fair weather will likely occur early next week.

Discussion For extreme southwestern california including orange...

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

stratus and fog had formed along the orange county coast, but most
of the san diego county coast was still clear at mid-evening. Some
dense fog could still develop overnight, based on the san clemente
island observation showing 1 4 mile vis and amdar soundings showing
a weak inversion just above the surface. Fog should mostly dissipate
by mid-morning Tuesday. The Wednesday Thursday storm system still
looks on track, but should not be a big precipitation
producer, mostly under 1 2 inch west of the mountains. No changes
were made to the forecast this evening.

From previous discussion...

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
190400z... Coast valleys... Areas of low stratus fog will occur along
the coast and up to 10 sm inland overnight. Timing is somewhat
uncertain at coastal airports, but bkn ovc cloud bases below 700 ft
msl and areas of vis below 3 miles, locally below 1 mile, are likely
at times. Most areas should clear by 17z with some clouds at above
15000 ft msl Tue afternoon. Stratus will likely redevelop by early
tue evening along the coast and spread inland.

Mountains deserts... Mostly clear skies with unlimited vis will
continue through Tuesday evening. Areas of west to southwest surface
winds 15-25 knots with gusts 30-40 knots will develop late Tuesday
afternoon and continue Tuesday evening from the mountain crests
to the desert foothills along with strong up downdrafts.

Marine
Patchy dense fog will likely continue overnight, with vis 1 nm 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
High surf of 5-9 ft in portions of san diego county will be possible
Wednesday through Thursday due to a building west swell of 6-9 ft in
the coastal waters at 15-17 sec from 280 degrees. Elevated surf of 4-
6 ft is possible in orange county, with strong rip currents both in
oc and san diego county. Swell and surf will subside on Friday. A
high surf advisory will likely be needed for san diego county.

Sgx watches warnings advisories
Ca... None.

Pz... None.

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.
