943 am pdt Mon sep 24 2018

Synopsis
High pressure aloft will build in from the west and eventually
overhead southern california by Thursday. This will lead to
building heat inland Wednesday through Thursday. For Friday into
next weekend, an upper level low off the west coast will move
inland into northern california, bringing stronger onshore flow
and a cooling trend for southern california.

Discussion For extreme southwestern california including orange...

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

Update...

the marine layer is locked in place from the coast extending
inland some 25 miles. Cloud thickness has increased and WRF run
shows some high surface rh along the immediate coast this
afternoon, indicative of the possibility of some cloudiness
remaining at the beaches this afternoon. However, slow clearing
will occur elsewhere. Temperatures will cool a few degrees from
yesterday. No changes were made to the forecast. See previous
discussion below for further forecast details.

Previous discussion (issued at 444 am pdt Mon sep 24 2018)...

high pressure to the south will bring a warming trend through
Thursday. Weak offshore flow will bring some locally gusty east to
northeast winds, mostly 25 mph or less, near the coastal slopes of
the mountains into the inland valleys at times for Tuesday into
Thursday, mainly nights and mornings, with the greatest warming
for the valleys and some inland coastal areas on Wednesday.

Through Tuesday, the marine layer and weak onshore flow will
bring areas of night and morning low clouds and fog, spreading
into portions of the inland valleys. For Wednesday through Friday,
the marine layer will become shallower with the coastal low clouds
not spreading as far inland.

Across the eastern pacific into the western states, the global
models are in good agreement into Friday, and in decent agreement
into Sunday with more significant spread beyond Sunday morning
into early next week. A closed low pressure system over the
eastern pacific is forecast to move towards the california coast
on Friday and into northern california on Saturday. This would
bring stronger onshore flow for southern california with a cooling
trend for Friday into next weekend.

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.
