Synopsis 20 930 am.

It will be partly cloudy today with a few mountain showers. Partly
to mostly cloudy conditions are expected this week with a slight
chance of showers over the mountains and interior valleys. High
temperatures will remain well below normal through the period.

Short term (tdy-wed) 20 905 am.

***update***
cool and breezy throughout the area this morning. It is raining to
our southeast over san diego county, but our precip should be
confined to a few north slope showers that end by mid-morning.

Biggest impact of the day will likely be the northerly winds this
evening, but they will only be at weak advisory-strength, if that
much.

***from previous discussion***
yesterdays upper low has exited the state and is now in nv. A few
showers are continuing in the NW flow around the backside of the
low. Most of the showers will end by dawn except over the north
slopes of the mtns near the kern county line. Some low clouds have
formed in eastern ventura county and the western san fernando
vly. Patchy low clouds have also formed across the central coast
as well. Hgts are a much blo normal 552 dm and MAX temps will come
in 3 to 6 degrees blo normal across the coasts... 5 to 10 degrees
blo normal for the vlys and 10 to 20 degrees blo normal for the
antelope valley.

There will be a decent north push tonight and wind advisories may
be needed for the i-5 corridor and the sba south coast.

Another cold upper low will move down the ca nv border Tuesday
settle over the las vegas area and then spin through Wednesday.

This system will bring partly ocnl mostly cloudy skies to the area
and a chance of light showers to the mtns the interior vlys and
the antelope through the period. MAX temps will remain similar to
today's with most non mtn sites seeing readings in the mid to
upper 60s.

Long term (thu-sun) 20 329 am.

Wednesday's upper low will eject to the ne. But in a somewhat
unusual twist a pos tilted upper level trof well retrograde into
the state. This trof will last until Friday when yet another cool
upper level low will rotate out of the pac NW into and then over
the state.

The weather will really not change skies will be generally partly
cloudy with a few periods of either mostly cloudy or mostly clear
conds. A low chc of mtn showers will persist through the period
focused on the north slopes.

Temps will not change much at all and will remain many degrees blo
normal through the period.

Gusty west to northwest winds will affect the mountains and
antelope valley through Tuesday. Gusty west to northwest winds
will affect coastal areas this afternoon and evening. There will
be some gusty northwest to north winds through and below passes

chance of gale force winds tonight in zones pzz673-676, and a
40% chance over the same areas late Tue afternoon into Tue night.

Large hazardous seas are expected through Wednesday due to a
combination of moderate period w-nw swell and steep wind waves.

be at or above small craft advisory (sca) levels through wed
night. Winds will likely reach SCA levels during the afternoon and
evening hours through wed.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
