PZZ500 314 Am Pdt Sat Aug 17 2019
Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Moderate to gusty northwesterly winds will continue over the northern and outer waters into Sunday as high pressure remains over the eastern pacific. This high pressure will begin to weaken into Sunday before a strong low pressure center develops and approaches british columbia early next week. The persistent fetch produced by these systems will generate fresh short period swell that will propagate into the california coastal waters. This short period swell in combination with gusty winds will generate hazardous seas conditions, particularly for smaller vessels.

Synopsis
Temperature will cool over the weekend with below average
temperatures by Sunday. Warming slowly through next week to a
little above average with triple digits in the valley by mid-week.

No precipitation expected over interior norcal through the
extended period.

Discussion
Relative to last night, most locations have seen a notable
decrease in overnight temperatures, generally in the 5 to 10
degree range. The erosion of the four corners ridge has allowed
mid-level heights to lower over northern california. Further
amplification in the northern stream flow this weekend will allow
temperatures to move below average by Sunday. Valley highs will
range from the mid upper 80s sacramento southward to the low 90s
over the northern sacramento valley. Such readings should continue
into Monday, thus offering some relief after multiple days in the
triple digits.

The shift in the pattern will also support a significant uptick in
the delta breeze. Through Monday morning, sustained wind speeds
around the delta region should be in the 25 to 35 mph accompanied
by higher gusts. The resultant southerly flow across the valley
will offer the noted relief from the earlier week hot
temperatures. Given the enhanced marine influence to the air mass,
there will likely be an increase in low clouds extending out of
the delta the next couple of nights mornings. This is supported by
nam model soundings as well as the href probabilities.

Looking beyond Monday, a strengthening trough off the coast will
build heights across the state by Tuesday. This ultimately brings
temperatures to near average after a multi-day cool down. ~bro

Extended discussion (Wednesday through Saturday)
Ensembles show high pressure peaking over the area around mid-
week before weakening slightly as a weak trough develops along the
west coast later next week. Temperatures will be around 5-10
degrees above average for late-august mid-week, cooling to
slightly above average toward the end of the week. &&

Aviation
Vfr conditions next 24 hours. Local southwesterly wind gusts 25-35
kts vicinity carquinez strait and west delta. Areas southerly wind
gusts 15-25 kts sacramento valley 22z-06z Sunday. Lighter winds
elsewhere.

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.
