Synopsis
A trough moving inland today will be replaced by higher pressure for
warmer days Wednesday and Thursday. Mountain and desert winds will
be lighter and the marine layer will be shallower. A low pressure
system moving across the great basin will bring minor cooling Friday
and Saturday along with gusty northwest winds to the mountains and
deserts. Warmer again Sunday and Monday with high pressure aloft off
the california coast.

Discussion For extreme southwestern california including orange...

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

the marine layer deepened to around 5000 feet last night, and a weak
trough generated just enough lift to generate a few light showers
this morning. Most of the precip fell across san diego county with
0.01" reported at julian, bonita, campo, mission valley, san diego
and fallbrook. The statocu deck will mix out this morning, but
scattered to broken clouds will linger into the afternoon due to the
deep marine layer. The cloud coverage will be greatest over san
diego county.

A vort MAX and associated speed MAX on the west side of a 546 dm low
in wyoming will race across nevada this morning and into northern az
this afternoon. Gusty NW winds will affect the mountains and deserts
again today, but they won't be quite as strong as yesterday.

The trough slides farther east tonight and an expansive eastern
pacific ridge will edge close enough to bring warmer days and
lighter winds Wednesday and Thursday. The marine layer will be a
little shallower, and night and morning coastal low clouds will be
less widespread.

*from previous discussion*
another trough of low pressure moving through the
great basin will bring slight cooling for Friday and Saturday with
gusty north to northwest winds for the mountains and deserts. High
pressure aloft off the california coast will bring weaker winds and
warming for Sunday and Monday with high temperatures warming to 5 to
10 degrees above average.

Aviation

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
