area forecast discussion
national weather service san diego ca
818 pm pdt Sun sep 23 2018

Synopsis
The tail end of an upper level trough will bring warm days and
comfortable nights with low humidity through Tuesday. A ridge of
high pressure building over the southwest will bring inland heat
Wednesday and Thursday before slight cooling occurs to close out
the week, though temps remain above normal.

Discussion For extreme southwestern california including orange...

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

the marine stratus was expanding over the coastal waters and locally
inland over coastal san diego county. Some was even spreading
northward across coastal orange county at 8 pm pdt. The 00z miramar
sounding had a 7c inversion based near 1850 ft msl. That's about 450
ft higher than yesterday evening, but cloud bases remain lower. The
sfc pressure gradient was up to 8 mbs onshore ksan to the lower
deserts but only slightly onshore to the ne. Peak wind gusts were
westerly at 28-38 mph, mainly through the desert passes. No forecast
changes this evening.

From previous discussion...

an upper level trough over the northern rockies will move to the
upper midwest through Tuesday. The tail end of this feature will
move across the SW states late Tuesday. The only consequence will
be slightly cooler temperatures than were felt yesterday. Dry
weather will continue. Gusty westerly winds will occur on the
desert mountain slopes and through the passes, especially this
evening with gusts of 30-40 mph.

The marine layer stratus will move quickly into the inland valleys
tonight. It cleared to the coast, but has since come back to some
of the sd beaches this afternoon and will spread and move inland
this evening... Some 15-25 miles. This will be the trend the next
few nights.

Upper level ridging will build along the west coast mid week and
become fully centered over southern california by Thursday. H5
heights rise to about 590 dm and h85 temps increase by a couple
degrees. This will allow temperatures to rise Wednesday-Thursday.

Given a cool bias of late inland and the height rises, have added
a few degrees to the warmest guidance, especially for the
typically hotter inland locales. Heat risk increases, but doesn't
quite hit issuance criteria, but will monitor trends.

The ridge breaks down late in the week as an upper level low cuts
off and spins off the california coast. Dry weather will continue
on prevailing southwesterly flow aloft and temperatures will
remain above normal, though not quite as hot as mid week.

Global models show the aforementioned upper low finally moving
east over norcal next weekend, possibly delivering the first fall
rains up that way, though nothing substantial. Socal stays dry.

Aviation
240300z... Coast valleys... Stratus continues to spread inland along
the coast of san diego and southern parts of orange county. Bkn ovc
stratus with bases 1000-1500 ft msl and tops to 2000 ft msl will
spread 15-25 miles inland, and briefly into areas of the inland
empire after 12z. Local vis 1-3sm in br will occur in the valleys
10z-16z mon. Stratus expected to clear most areas 16z-19z Monday.

Some stratus may persist Monday afternoon along the immediate coast,
especially in san diego county.

Mountains deserts... Few cirrus above fl150. Otherwise, mostly clear
with unrestricted vis through Monday.

Marine
No hazardous marine weather is expected through Friday.

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.
