Synopsis
The tail end of an upper level trough will bring warm days and
comfortable nights with low humidity through Tuesday. A ridge of
high pressure building over the southwest will bring inland heat
Wednesday and Thursday before slight cooling occurs to close out
the week, though temps remain above normal.

Discussion For extreme southwestern california including orange...

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

an upper level trough over the northern rockies will move to the
upper midwest through Tuesday. The tail end of this feature will
move across the SW states late Tuesday. The only consequence will
be slightly cooler temperatures than were felt yesterday. Dry
weather will continue. Gusty westerly winds will occur on the
desert mountain slopes and through the passes, especially this
evening with gusts of 30-40 mph.

The marine layer stratus will move quickly into the inland valleys
tonight. It cleared to the coast, but has since come back to some
of the sd beaches this afternoon and will spread and move inland
this evening... Some 15-25 miles. This will be the trend the next
few nights.

Upper level ridging will build along the west coast mid week and
become fully centered over southern california by Thursday. H5
heights rise to about 590 dm and h85 temps increase by a couple
degrees. This will allow temperatures to rise Wednesday-Thursday.

Given a cool bias of late inland and the height rises, have added
a few degrees to the warmest guidance, especially for the
typically hotter inland locales. Heat risk increases, but doesn't
quite hit issuance criteria, but will monitor trends.

The ridge breaks down late in the week as an upper level low cuts
off and spins off the california coast. Dry weather will continue
on prevailing southwesterly flow aloft and temperatures will
remain above normal, though not quite as hot as mid week.

Global models show the aforementioned upper low finally moving
east over norcal next weekend, possibly delivering the first fall
rains up that way, though nothing substantial. Socal stays dry.

Aviation
232000z... Coast valleys... Local bkn stratus will occur along the
beaches this afternoon. Bkn ovc stratus with bases 1300-1600 ft msl
and tops to 2000 ft msl will start spreading along the coast 04z-08z
and eventually up to 25 miles inland by 12z. Areas of higher terrain
will be obscured, and local vis 1-3 miles will occur in the valleys
10z-16z mon. Stratus will clear most areas 16z-19z mon, though local
stratus could persist along the beaches Mon afternoon.

Mountains deserts... Sct-local bkn clouds at above 7000 ft msl will
continue this afternoon over the mountains. Otherwise, mostly clear
with unrestricted vis through Monday.

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.
