Synopsis
High pressure aloft will bring another hot summer weekend to the
region. Relief from the heat will be found at the coast and in the
higher mountains where temperatures will be closer to average.

Monsoon moisture will return early next week with chances for
afternoon thunderstorms over the mountains and deserts Tuesday
through Thursday.

Discussion For extreme southwestern california including orange...

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

thunderstorms over the mountains this afternoon were not as
widespread as yesterday, but a strong one formed over the cranston
fire burn scar and dropped about an inch of rain in 1 hour. It
resulted in flash flooding and debris flows in the burn area, and
prompted the closure of highway 74.

The storms dissipated by early evening and that should be the end of
our thunderstorm threat for a couple days as drier air associated
with strong high pressure aloft builds over southern california.

There will be downward trend of atmospheric moisture this weekend.

The pw over the mountains of 1.30" today lowers to 0.80" Saturday,
then rises slightly Sunday to 0.90". Synoptic scale subsidence with
the high aloft coupled with a drier atmosphere will limit the
cumulus growth over the mountains each afternoon.

On Monday, the upper ridge moves east over az and nm and that will
reestablish a south to southeasterly monsoon return flow into socal
next week. The pw Monday rises to 1.10", then to 1.20" Tuesday and
Wednesday, and then to 1.40" Thursday. This is reflected in the
forecast that has incrementally increasing thunderstorm coverage
over the mountains and deserts each day. The storms will drift north-
northeast off the mountains and into the deserts due to prevailing
south-southwest above 500 mb.

Night and morning coastal clouds will spread across the coastal
areas and into the western valleys each day. It'll be another very
warm hot stretch of weather through the middle of next week, but
it's august so that's not all that surprising.

Aviation
180400z... Coasts valleys... Bkn ovc stratus will gradually spread up
to 30 miles inland overnight, including far west and south parts of
the inland empire. Bases will be 1300-1700 ft msl with tops to 2000
ft msl, and higher terrain will be locally obscured. Local vis below
3 miles will occur in the valleys due to fog, 09z-15z sat. Most
areas will clear by 17z sat, except for local bkn CIGS remaining
near the beaches through Sat afternoon.

Mountains deserts... Few-sct clouds at above 10000 ft msl with
unrestricted vis will prevail through Saturday.

Marine
No hazardous marine weather is expected through Wednesday.

Beaches
Beach hazard statement will continue through Saturday for elevated
surf and strong rip currents. A 4 ft 16-17 second period swell from
180 degrees will bring surf of 3-6 ft, with isolated sets to 9 ft,
mainly along the south facing beaches of northern orange county, and
strong rip currents. Surf will lower Saturday night through Sunday.

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

Sgx watches warnings advisories

county coastal areas-san diego county coastal areas.

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.
