Marine Weather and Tides
Plymouth, 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
Dry with warm daytime temperatures this week, becoming hot Friday
through Sunday.

Discussion
Large upper low centered over SW idaho with associated troughing
extending over norcal. Visible satellite imagery showing extensive
stratus along the coast extending into western portions of the
delta. Widespread stratus and fog also evident over plumas county
which will gradually burn off. Sunny skies expected across the
cwa today with some afternoon CU tcu developing over the eastern
mountains. Higher resolutions models suggest a slight chance of
an afternoon shower or thunderstorms over the mountains of eastern
shasta and plumas counties. Moderate delta breeze at this time
will trend down through late morning. Heights and thicknesses
increase today as upper low to the east fills and short wave
ridging off the coast approaches. Above normal high temperatures
forecast today with mid to upper 90s expected in the central
valley.

Offshore upper ridging progged to build and progress inland
through midweek with dry weather and continued above normal
temperatures. Short wave upper troughing skirts through northern
portions of the CWA Wednesday night into Thursday morning. Gfs-20
generates some convective precip over the shasta mountains during
this time frame, while nam12 and ecmwf-hires keep precip threats
north of the forecast area. Mid to upper 90s continue to be
forecast in the central valley through Thursday.

Pch
.Extended discussion (Friday through Monday)
dry and very warm weather is expected through the end of the week
as pacific upper level ridging expands eastward into the region
and builds. Widespread triple digits are expected across the
valley by Friday, with even hotter temperatures expected on
Saturday. This will bring the potential for moderate heat risk for
sensitive groups including the elderly and the very young for
Friday, potentially areas with areas of high risk on Saturday.

Breezy north winds will bring lower humidity levels and increasing
fire danger. Sunday may be slightly less hot, as a trough moving
through the pacific northwest flattens the ridge and shifts the
axis eastward. Cooler weather returns on Monday, with valley highs
dropping to around 90. Ek &&

Aviation
Vfr conditions continue over the next 24 hours. Dry weather is
expected except for isolated showers or thunderstorms possible
over the lassen park area this afternoon. Winds at TAF sites will
generally less than 10kt. Ek

Sto watches warnings advisories
None.

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.
