Marine Weather and Tides
Laguna Niguel, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

845 pm pdt Mon jul 16 2018

Synopsis
Increasing monsoonal moisture combined with an upper level
disturbance from the east will bring chances of showers and
thunderstorms to the mountains and deserts Tuesday through Thursday.

A few storms may drift into the valleys or coastal areas Tuesday
night. The weekend will be dry with seasonal summer weather. This
will be followed by hotter weather next week as strong high pressure
builds over the southwest.

Discussion For extreme southwestern california including orange...

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

the 00z nkx sounding had a higher pwat (1.63") than the 12z sounding
(1.52"), but was more stable with a CAPE of 0 j kg at 00z compared
to a 269 j kg at 12z. So the few light showers that drifted over the
san diego county deserts early this afternoon were vaporized as they
moved into a more stable airmass. Low clouds returned to the coast
this evening and will spread about 10 miles inland again tonight.

On Tuesday the atmosphere becomes a little more unstable from the
combined effects of a further increase in moisture and an easterly
wave moving in from the southeast. Desert pwats rise to 2.00"
Tuesday afternoon and peak at 2.25" Tuesday evening. Thunderstorm
chances will be higher tomorrow in the mountains and deserts,
especially in the afternoon and evening. Any storms that form may
drift into the valleys or coastal areas Tuesday night in the deep
layer mid level easterly flow in 600-300 mb layer.

The easterly flow between the upper ridge over the great basin and
the upper low over central baja will continue into Wednesday. A
second easterly wave tracks across socal northern baja Wednesday,
and even though the pwats decrease slightly, there will still be
sufficient moisture for continued chances of afternoon t-storms over
the mountains and deserts.

On Thursday the ridge drifts over the four corners region, and the
easterly wave moves northwest out over the pacific and up the coast
about 300 miles offshore. Thunderstorms chances over the mountains
and deserts decrease Thursday as the atmosphere continues to dry out
and become more stable due to the closer proximity of the upper
ridge. This trend continues Friday through Sunday when the ridge
becomes the dominant player and eliminates the thunderstorm threat.

A shallow marine layer will continue near the coast.

Next week will be hotter. A 596 dm high is forecast over arizona
next Monday through Thursday, and temperatures will be 3-6 degrees
above average most of next week.

Aviation
170250z... Coast valleys... Areas of low clouds with bases 1200-1500
ft msl and tops to 1800 ft msl beginning to spread inland and
impacting coastal TAF sites at this hour. Low clouds expected to
spread up to 10 miles inland by 15z with areas of reduced vis on
elevated coastal terrain. Expect clearing to the coast between 15z
and 17z tue.

Mountains deserts... Sct-bkn clouds at above 10000 feet msl with
unrestricted visibility will prevail through tue. Better chances for
tstm on Tue with mountain obscurations possible in any shwr tstm
activity along with locally gusty and erratic winds.

Marine
No hazardous marine weather is expected through Saturday.

Skywarn
Skywarn activation may be requested Tuesday and Wednesday.

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.
