Synopsis
The offshore flow will weaken into Wednesday with some moderation in
temperature and humidity expected as winds turn briefly onshore.

Stronger offshore flow returns again late Wednesday night through
Friday morning, with more hot and very dry conditions. The winds
should drop off late Friday and turn back onshore on Saturday but it
will still be warm and quite dry inland. A large trough developing
over the west will bring cooling for Sunday into early next week.

Discussion For extreme southwestern california including orange...

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

it was clear over the forecast area at midday. Easterly winds have
dropped off some but there were still a few peak gusts in wind-prone
areas of around 35 mph. Temperatures were soaring into the 90s west
of the mountains. A heat advisory remains in effect for the
coast valley areas this afternoon.

A strong ridge off the coast will drift east over california as a
trough deepens over the great plains. Winds will weaken and turn
briefly onshore into Wednesday, then back offshore again Thursday
and Friday as the high builds overhead. The stronger offshore winds
will be confined mostly to the inland valleys, mountains and coastal
foothill areas but some wind and very low relative humidity will be
felt all the way to the coast. There is a potential for some strong
wind gusts to break (over 60 mph) in favored spots on below the
western slopes of the san diego county mts later Thu Fri morning but
not expected to be widespread or damaging based on current model
data.

The pattern breaks down fairly quickly over the weekend as the high
weakens, and another trough digs south over the rockies, forcing
winds back onshore. This will bring cooling and higher humidity
inland through early next week.

Temperatures are well above average today, and will be again on
thu Fri with some slight cooling on Wednesday. Heat advisories may
be needed again Thu fri.

Aviation
222000z... Local northeast wind gusts to 25 kt will develop tonight
into Wed morning, mainly in foothills, below passes and canyons in
orange and san bernardino counties, and locally into the inland
empire. Llws and moderate up downdrafts are possible over and
west southwest of the mountains. Otherwise, clear skies will
continue through wed.

Marine
No hazardous marine weather is expected through Sunday.

Fire weather
Red flag warning Thursday morning through late Friday...

weak to locally moderate offshore flow will weaken this evening
below the coastal slopes of the mountains passes. Rh values of
10-15% will trend up into the 25-30% range overnight, but quickly
fall again inland to around 10% on Wednesday. Weaker winds on
Wednesday will turn back onshore west of the mountains in the
afternoon, continuing the modest rh recovery over coastal and
western valley areas.

Another round of stronger offshore flow is expected late Wednesday
night through Friday. Northeast winds 20-30 mph with gusts around
50 mph should be underway over northern, wind-prone areas areas like
the cajon pass early Thursday morning, developing rapidly south over
slope foothill areas and passes around sunup. Peak gusts in wind-
prone areas may reach 60-65 mph but should be isolated. Minimum rh
of 5-10% looks likely over most of the area. The greater area of
higher wind speeds and lower rh should result in extended periods of
red flag conditions both Thu fri, prompting a red flag warning all
mtn and valley areas Thu through Fri including o.C. Inland.

The winds will weaken Friday afternoon but very low, single-digit rh
is likely to continue into Saturday in many areas. By Saturday
afternoon the recovery will begin as onshore flow increases,
spreading higher rh inland through Sunday.

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

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.
