Synopsis
High pressure aloft near the west coast will bring an inland
warming trend through memorial day with high temperatures warming
to a little above average. The marine layer will become not quite
as deep... But with night and morning low clouds and patchy fog
still extending into portions of the inland valleys for Sunday
and Monday mornings. A trough of low pressure near the west coast
will bring cooling and a deeper marine layer for the middle part
of next week. Slow inland warming and a slightly shallower marine
layer are possible towards the end of next week.

Discussion For extreme southwestern california including orange...

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

Short term (today through Monday)
High pressure aloft near the west coast today... Will move slowly
inland on Sunday... Then begin to weaken on memorial day as a
trough of low pressure over the eastern pacific moves toward the
west coast. Inland high temperatures will slowly warming through
Monday with high temperatures near average on Sunday and a little
above average on Monday.

Early this morning the marine layer is still near 3500 to 4000
feet deep with widespread stratus coverage over land areas from
the coast inland to the lower coastal mountain slopes. Some gaps
in the stratus coverage over the coastal waters are continuing to
close. The marine layer is expected to become a little less deep
through Monday... But still deep enough for night and morning
coastal low clouds and patchy fog to extend into portions of the
inland valleys for Sunday and Monday mornings.

Long term (Tuesday through Friday)
A trough of low pressure will move inland along the west coast on
Wednesday with some spread among the global models with the
details. Greater spread develops from Thursday into next weekend
with periods of weak high pressure or weak low pressure aloft that
may spread across southern california. Inland cooling and
deepening of the marine is expected for the middle part of next
week. Some slow inland warming and slightly shallower marine layer
are possible towards the end of next week.

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.
