Synopsis
A santa ana weather pattern will bring gusty winds to the mountains
and foothills tonight and Thursday. Thursday will be a warmer day in
the coastal and valley areas, and a cooler day in the mountains and
deserts. The weather will be dry and mild through the weekend,
followed by clouds and perhaps a chance of light rain Monday as a
weak trough moves inland. On Tuesday, high pressure builds over the
southwest for dry, mild weather through Friday.

Discussion For extreme southwestern california including orange...

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

Update...

patchy low clouds are seen off the coast on satellite imagery.

Offshore flow should keep these off the coast. Offshore winds will
pick up through the passes and along the coastal mountain slopes.

30 mph reported just below the cajon pass past hour. Latest wrf
is not aggressive with wind speeds, and this model usually
overdoes speed. Gusts in the most wind prone locales could reach
40+ mph, but not meeting advisory criteria and no significant
impacts are expected. See previous discussion below for further
forecast details.

Previous discussion (issued at 210 pm pst Wed dec 12 2018)...

pressure gradients from the great basin have trended offshore at a
pretty good pace since sunrise, increasing from 0.0 to -6.3 from san
diego to tonopah. A shallow marine layer kept temperatures in the
mid 60s in the coastal and valley areas early this afternoon, which
is a little below average. Mountain and desert areas will be a
little above average today.

This temperature regime flip-flops on Thursday with the onset of a
santa ana pattern that will bring warming west of the mountains and
cooling to the mountains and deserts. Coastal and valley highs will
be in the 70s, with an 80 degree high possible at some sites in
inland orange county sites where downslope warming will be the
greatest. Mountain highs will in the 50s, high desert highs in the
upper 50s, and lower desert highs in the upper 60s to low 70s.

As for the winds, a 1040 mb surface high settles over southern
idaho, strong enough to support a period of gusty offshore winds
later tonight through Thursday morning. This won't be a terribly
strong offshore wind event, but there will be gusts to 45-50 mph in
the windiest santa ana prone mountain passes and eastern valleys.

The offshore winds abate Thursday afternoon through Friday morning,
followed by weak onshore flow Friday afternoon.

On Saturday and Sunday a weak trough passes through bringing high
clouds but nothing much more than that. Temperatures will be a
little warmer than average, and winds will be fairly light.

A pacific trough moves inland Monday for cooler weather and small
chances of light rain. The ECMWF continues it's stronger, wetter
trend with a closed low traversing socal Monday. The GFS is much
weather with a more progressive wave moving inland farther north
across central california. On Tuesday a high amplitude ridges builds
in behind the trough and will bring sunny, mild days through Friday.

Aviation
130415z... A few low clouds with bases around 1500 ft msl will
continue along the coast through about 09z. CIGS at the coastal taf
sites are unlikely, though some may have a brief period of 3-5 sm
vis in br 06-10z. Otherwise a few high clouds and unrestricted vis
through Thursday evening.

Ne-e surface wind gusts of 30-40 kt are possible Thu morning along
coastal mountain slopes and below the passes and canyons. Winds will
weaken Thu afternoon.

Marine
No hazardous marine weather is expected through Sunday. A large wnw
swell arriving Monday may generate combined seas of over 10 ft.

Skywarn
Skywarn activation will not be needed through the week.

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.
