Stronger onshore flow will bring a cooling trend through Thursday
with high temperatures returning to near average for Wednesday and
Thursday. Low clouds and fog will return to coastal areas tonight,
and spread into some valleys into Thursday morning. Slightly warmer
Friday under weak high pressure, then seasonal summer weather
prevailing through the holiday weekend.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
satellite imagery this evening showed clear skies prevailing over
socal once again, but marine clouds were gathering over the bight
and spreading toward the coast. The 00z miramar sounding had a weak
inversion based near 1500 ft msl and weak west winds below 3k ft.
The inversion was about 300 ft higher than last night, and the
inversion top was 5 degrees c lower than yesterday at 00z. Surface
pressure gradients showed good onshore trends, continuing to support
westerly winds of 15-25 mph with peak gusts of 35-45 mph through
wind-prone mtn pass desert areas.
A red flag warning remains in effect from the mtn crests, east into
the deserts of riverside and san diego counties. No forecast changes
this evening, cooling is on track.
From previous discussion...
temperatures are a few degrees lower at 1 pm today than they were
yesterday at this time, except for the lower desert. A brand new
marine layer has come off the factory floor (along the central
coast), and this shiny new marine layer will drive into the southern
california showroom tonight. This appears to be in response to a
shortwave moving by to our north, which has also flattened out the
monster ridge responsible for our recent heat. The relaxed intensity
of the high will help the intense heat take a chill pill in the
interior away from the marine layer, and the marine layer cruising
into southern california will take care of the cooling west of the
mountains. Daytime temperatures will be noticeably lower Wednesday
and Thursday, especially west of the mountains. This new low cloud
deck is not a dense fog deck as was its predecessor at the coast
this morning. As the new coastal clouds move ashore, there might be
dense fog briefly on coastal mesas and hills, but true fog with low
visibility will not be an issue at the coast itself. As it moves
ashore this evening it should deepen overnight enough to spread into
western valleys. For the coming week, the stagnant summertime|
pattern will have only very minor fluctuations between the influence
of a weak ridge or a weak trough over southern california. Right now
we see relatively cool Wednesday and Thursday followed by a slightly
warmer Friday and Saturday, a cooler Sunday and Monday, and a warmer
fourth of july. The coastal clouds will make it into some of the
westernmost inland valleys during the nights.
280400z... Coast valleys... Stratus will gradually develop tonight
over coastal areas, spreading into some valleys, to 15-25 miles
inland by 12z wed. Bases will be 800-1100 ft msl with tops to 1500
ft msl. Kcrq will have a cig very soon with ksan likely by 06z and
ksna around 08z. Local vis below 1 mile will occur in some coastal
valleys, including vcnty krnm mainly 10z-15z. Most areas will clear
15z-18z wed, with stratus returning early Wed night.
Mountains deserts... Clear skies with unrestricted vis will prevail
through Wed evening. West winds gusting 30-40 kt will occur over and
east of the mountains through 12z wed, producing llws and mdt
up downdrafts over and east of the mountains.
No hazardous marine conditions are expected through Sunday.
Very low rh will continue over the deserts and desert slopes of the
mountains through Wednesday with slight recovery Thursday. Winds
will become more localized however, limiting the areas and periods
of critical fire weather conditions, and confining them largely to
the deserts where fuel is limited. So the red flag will be allowed
to expire late tonight.
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
