Marine Weather and Tides
Little River, 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.

Synopsis Interior valley temperatures will warm into the 80s
this afternoon, with cooler 70s expected Wednesday afternoon
through the weekend. Near the coast, a persistent marine airmass
will favor temperatures in the 50s to near 60. Otherwise, isolated
thunderstorm development will be possible Tuesday and Wednesday
afternoon over the interior mountains. Widespread showers will
become probable Thursday through Saturday.

Discussion An upper low was centered over far southern nevada
early Tuesday morning, and an amplified ridge was present over the
west coast. At the surface, northerly winds were occurring over
the coastal waters of wa, or, and ca, and were accompanied by
widespread marine stratus. Latest model guidance indicates the
stratus (along with possible drizzle) will persist through at
least midweek, and perhaps beyond. In addition, the stratus will
continue to penetrate the adjacent coast, and will subsequently
inhibit strong daytime heating resulting in highs in the mid upper
50s to around 60. Farther inland, plentiful sunshine will aid in
Tuesday afternoon highs in the 80s. Surface heating will also
yield strong boundary layer destabilization favorable for isolated
shower and thunderstorm development over the trinity alps and
yolla bolly mountains Tuesday afternoon, and again Wednesday
afternoon.

During Thursday, an upper low is forecast to approach the ca
coast. Lobes of ascent will spread downstream from the low and
increase the probability of area-wide shower development. Cloud
cover will also thicken and increase in areal coverage resulting
in noticeably cooler afternoon highs over the interior. Model
guidance shows the upper low passing south and exiting east of
nwrn ca Friday night into Saturday. The atmosphere will experience
drying in the wake of the low resulting in shower dissipation and
clearing skies by late weekend over much of the interior.

Thereafter, weak upper ridging will prevail across the area
through early next week, which will favor moderating temperatures
across interior valleys.

Aviation The marine stratus is back! During the evening hours,
the breaks in the coastal marine stratus were all filled back up.

Conditions were bouncing between MVFR ifr for kacv and kcec
during the overnight hours. Meanwhile, kuki remainedVFR
overnight. Do expect kuki to remain cloud free through the
forecast period.

Not really good news for aviation in kcec and kacv. Models are
hinting on conditions to worsen during the day today as marine
stratus deepens. Do expect conditions to mostly stay as ifr MVFR
for both kcec and kacf during the day. Conditions will drop to
ifr lifr during the overnight hours tonight.

Marine We are still dealing with some gusty north winds and
steep seas over NW california waters for today. Small craft
advisory in effect through this afternoon for the inner waters,
and through tonight for the outer waters. Do expect conditions to
improve by tomorrow.

Do expect light north winds on Wednesday. Winds will flip to the
south on Thursday as a weak low remains offshore. Winds will shift
back to the north on Friday. Do expect moderate north winds for
the first part of the memorial day weekend. Models are hinting on
further increase in north winds for the second half of the
memorial day weekend.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory until
5 pm pdt this afternoon for pzz450- 455.

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.
