area forecast discussion

854 pm pdt Sat aug 19 2017

Synopsis
Low pressure parked off the socal coast will keep the weather
cool for mid-summer, and support considerable marine cloud
development nights and mornings through Monday. Temperatures will
remain below average into midweek, with modest warming expected
during the latter half of the week as the low dissolves and the
marine layer thins. A few showers and thunderstorms are possible for
the mountains and high desert about Monday, otherwise fair and dry
weather will prevail.

Discussion For extreme southwestern california including orange...

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

at 8 pm pdt... Marine stratus was spreading inland along the coast,
with clear skies inland. The 00z miramar sounding had a 6 degree c
inversion based near 2100 ft msl. Except for near-sfc, winds in the
column were south 5-15 kts up through 12k ft and the profile was
exceptionally stable with dcape values over 4000 j k. Sfc pressure
gradients were around 8 mbs onshore to the local deserts. This is
supporting local winds of 15 to 25 mph with peak gusts through the
passes of 35-40 mph.

The forecast appears to be on track so no updates are expected this
evening.

From previous discussion...

coastal clouds took time to clear from the coast today and some
cumulus have developed over the mountains. Otherwise, skies are
beautifully blue and temperatures are mild. A weak low pressure
trough off the coast will sit and spin for a few days. On Sunday
and Monday the southeast flow in front of the trough will draw
monsoon moisture out of sonora and arizona into southeast
california, specifically nosing into san bernardino county. The
moisture and instability are barely sufficient on Monday to
forecast a slight chance of showers and thunderstorms in the
mountains and high desert, mainly in san bernardino county. This
morning's guidance supports a light touch on this forecast. The
low pressure trough will also deepen the marine layer and extend
coastal clouds a little farther inland Sunday and Monday mornings,
filling most of the coastal basin. Temperatures will be mild for
mid-august through most of next week. The low pressure trough
weakens Tuesday and Wednesday before dissolving Thursday and
Friday. The resulting higher pressure aloft will bring a warming
trend Friday and Saturday along with a shallower marine layer.

Aviation
200330z... Coast valleys... Low clouds with bases around 1500 ft msl
and tops near 3000 ft msl will continue to spread inland through
14z. Look for visibility to fall to 3 sm or less in the vicinity
higher valley terrain. Slow clearing is anticipated Sunday morning
with low clouds not retreating to the coast until sometime between
17z and 20z. Areas of low clouds will linger along the coast and
over the coastal waters between 20z Sunday and 00z Monday. Light
westerly sea breezes and skc will prevail over inland areas for the
same time period.

Mountains deserts... Mostly clear skies and unrestricted visibility
through Sunday night.

Marine
No hazardous marine weather is expected through Thursday evening.

Beaches
A 2-3 ft 14-15 sec period swell from 200 degrees will continue
through the weekend, producing surf of 4 to 5 ft north of carlsbad.

Strong rip currents will accompany the surf. High tides each evening
will peak around 6.5-6.8 feet, possibly leading to minor tidal
overflow. A beach hazards statement remains in effect through Sunday
evening.

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

Sgx watches warnings advisories

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.
