Synopsis
Cooler weather is in the forecast through Friday as a weak trough
of low pressure moves through the region. Low clouds west of the
mountains this morning may only partially clear today and then
move farther inland into the coastal slopes and passes tonight.

Strong and gusty winds will occur in the mountains and deserts
through early Friday. The trough may create scattered light
showers over and west of the mountains late tonight through early
Friday morning. High pressure aloft will rebuild over the west
this holiday weekend for warmer weather and a shallower marine
layer. Another cooling trend may begin next Tuesday as another
trough develops near southern california.

Discussion For extreme southwestern california including orange...

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

morning visible satellite shows widespread marine layer stratus
over the coastal waters, coast, and valleys, with mountain wave
clouds over the southeast san diego deserts and imperial county.

Elsewhere, skies were clear. Water vapor satellite shows a short-
wave trough offshore of point conception and a deeper, stronger
trough over the inter-mountain west. The 12z miramar sounding
showed significant deepening of the marine layer, with a 10 deg c
inversion noted at around 3500 feet msl. Onshore flow continues to
strengthen as well, with onshore pressure gradients from san
diego to las vegas up to 14.6 mb, compared to 7.1 mb at this time
yesterday. Winds in the mountain ridges, desert slopes and passes
are gusting around 30-40 mph, with the highest gusts of 57 mph in
the san gorgonio pass area. Although hi-res models show winds
weakening slightly today, they should increase again tonight as
the short-wave moves through southern california tonight into
Friday morning. A wind advisory continues for the san gorgonio
pass area and the san diego county deserts through 8 am Friday,
with gusts of 55 mph and locally 65 mph likely. Also, with the
strong onshore flow and deep marine layer, typically this results
in only partial clearing of marine layer clouds at best during the
day. The marine layer will deepen further tonight, up to around
5000 feet msl. The short-wave moving through the region will
likely bring scattered light showers over and west of the
mountains tonight into early Friday morning, with scattered
amounts of 0.01-0.05 inches. Many places may only see a trace. The
colder air mass will result in highs 5-10 degrees below normal
today and up to 15 degrees below normal on Friday.

A ridge to the west will start to strengthen and build over the
region Saturday through Monday, resulting in increasingly warmer
days and a shallower marine layer. By Sunday, highs will reach
back above normal, and then perhaps 5-10 degrees above normal on
Monday. Night and morning stratus will likely only affect the
coastal and western valley areas.

A trough will develop over southern california baja Tuesday
through Thursday, with a closed low perhaps developing. This may
result in another cooling trend and perhaps some deepening of the
marine layer.

Aviation
251415z... Coast valleys coastal mountain slopes... Low clouds with
bases generally 2500-3500 feet msl. Conditions likely to remain bkn-
ovc through much of the afternoon. Tops near 4000 feet increasing to
4500-5500 ft msl by Friday morning. Coastal mountain slopes mostly
obscured below 5500 feet msl through Fri morning. Risk of bkn-ovc
all day low clouds at ksan is moderate-high. Confidence in ksan taf
cloud coverage and base height is moderate-high. Isolated showers
Friday morning around 25 12z-25 18z.

Mountains deserts... Southwest to west winds with surface gusts 35-45
kt along the desert slopes foothills and through the passes
continuing through Fri morning with moderate to strong up and
downdrafts along with pockets of wind shear over and NE E of the
mountains.

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.
