Synopsis
High pressure building over the great basin will bring warm, dry
weather through Saturday. This santa ana pattern will also bring
gusty offshore winds to the mountains, foothills and inland valleys.

On Sunday and Monday an upper level trough moving inland through
central california will bring some clouds to the mountains and
deserts. It will also bring back night and morning low clouds and
fog to the coastal and valleys areas.

Discussion For extreme southwestern california including orange...

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

the current santa ana weather pattern will bring clear skies and
warm days Friday and Saturday. Downslope adiabatic warming will push
high temperatures into the low to mid 90s in the inland empire and
inland orange county. Coastal zone highs will be in the 80s as will
the san diego valleys. Mountain highs will range from the 50s-70s,
depending on elevation, the high deserts will be in the upper 70s,
and the low deserts from 88-93. This is one of those scenarios where
the highest temperature in our region will be in the ie or orange
county instead of the lower deserts on Friday.

The warm, dry weather combined with the gusty northeast santa ana
winds from 15-30 mph with gusts to 45 mph in the mountain passes,
foothills and valleys will elevate fire weather concerns. A red flag
warning will be in effect from 3 am to 10 pm Friday. Somewhat
lighter winds and better humidity recovery is expected on Saturday.

On Sunday the synoptic pattern changes. A trough of low pressure
will move inland across california bringing some cooling, onshore
flow and the return of marine layer clouds to the coast. Low clouds
will first arrive Saturday night at the coast, initially low enough
for possible pockets of dense fog in a few places. But a coastal
eddy spins up Sunday morning that will lift the cloud bases and
allow the low clouds to move several miles inland across the coastal
zones.

The trough will draw modest amounts of moisture in from the
southeast, primarily over the mountain and desert areas where the
precipitable water increases to 0.75". Most of the precipitation
will likely remain over the eastern san bernardino and riverside
county deserts.

Monday through Friday: the trough drifts east and is replaced by
weak ridging aloft for dry, mild weather next week. Temperatures
will be a little above average for the fourth week of october.

Aviation
182030z... Clear skies, unrestricted visibility and generally light
winds through tonight. Winds will begin to pick up in the mountains,
foothills and valleys Friday morning with N to NE winds 30-40 mph
and gusts to 50 mph. Llws likely Friday at kont and ksbd 07-11z and
at ksna 09-13z as winds begin to surface. Mod-stg uddfs on coastal-
facing mountain slopes. Winds will begin diminish around 02z
Saturday.

Marine
No hazardous marine weather is expected through Wednesday.

Fire weather
A red flag warning will be in effect from 3 am to 10 pm Friday.

Northeast winds will be strongest in the passes, foothills and in
the inland empire below the cajon pass. Lowest daytime humidity will
be from 10 to 15 percent.

On Saturday there will be slightly better humidity recovery with
lowest rh around 20 percent. The winds will also be a little
lighter.

Onshore flow will return Sunday into early next week with a cooling
trend for coastal and valley areas and a further recovery in
humidity.

Skywarn
Skywarn activation will not be needed today.

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.
