125 pm pdt Fri oct 18 2019
synopsis... Fair, dry, and warm weather is expected through much of
next week. Stronger offshore flow will generate locally gusty
northeast winds to 35 mph late Saturday night into Sunday afternoon.

A warming trend is expected Sunday through Tuesday.

Discussion For extreme southwestern california including orange...

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

Short term (today through Monday)...

northwest flow aloft will be present through Sunday with high
pressure aloft off the california coast and a trough of low pressure
over the rockies. Patchy low clouds over the coastal waters and
immediate coast still a possibility tonight as a brief coastal eddy
may spin up with weak southerly flow through the evening. Breezy
west winds are expected in the high desert Saturday evening with
gusts to 30 mph. Winds look to calm briefly before picking back up
turning on the switch for our next offshore wind event. Winds will
start to increase Sunday morning and afternoon from the north
impacting all mountain areas into the inland empire, though looking
fairly light in parts of san diego county. Monday has trended with
weaker offshore flow per WRF guidance. Dew point temps will lower,
creating drier conditions. A large area of high pressure off the
coast will begin to move eastward and plant itself over california.

This will bring a significant bump in the high temperatures, ranging
from mid 80s at the coast to mid 90s inland.

Long term (Tuesday through Friday)
The aforementioned high pressure system will continue the fair,
warm, and dry weather, which will peak on Tuesday. The offshore
pattern will weaken leading to a cooling trend, but temperatures
will remain a touch above average.

Another shortwave trough will dig into the rockies by Thursday and
lead to offshore flow with the possibility of gusty winds in the
mountains Thursday and Friday, though confidence is low at this time.

Aviation
182000z... Coast... Mostly clear skies for rest of today. Patchy low
clouds with bases below 1000 ft msl and fog may develop after 08z
sat along the immediate coast, especially in san diego county.

Confidence in CIGS and vis restrictions at the coastal airports is
low. Any low clouds that do form will scatter out by 16z sat.

Valleys mountains deserts... Mostly clear with unrestricted vis
through Sat morning.

Marine
No hazardous marine conditions expected through Wednesday.

Fire weather
Seasonal temperatures are expected through Saturday evening with
prevailing onshore flow and moderate rh most areas.

On Sunday... Northerly winds will increase through the cajon pass and
spread south over the santa ana mountains at 15 to 25 mph with peak
gusts near 35 mph in the wind-prone areas. Increased northeast to
east winds are possible through the morongo and san gorgonio passes
as well. This will be accompanied by 10-15% rh and higher
temperatures, resulting in elevated fire weather conditions.

On Monday, conditions are expected to deteriorate further as
temperatures rise into the 90s with areas of east to northeast winds
of 15 to locally 30 mph along all the coastal foothills and through
the passes. Minimum rh of 10-15%, along with gusty winds near the
foothills may result in critical fire weather conditions at times,
but duration will be limited most areas.

It will remain very warm and dry on Tuesday with elevated fire
weather conditions due to very low rh, but winds will be light.

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

Sgx watches warnings advisories

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.
