Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Northwest winds are forecast to prevail over the coastal waters today. Winds will increase this evening and tomorrow as surface high pressure builds over the eastern pacific. Moderate to strong winds are expected over the weekend. These winds will generate steep fresh swell resulting in hazardous seas conditions, particularly for smaller vessels. A long-period southerly swell train will arrive today and persist through the weekend. This will cause occasional breaking waves over nearshore shoals and strong currents along the coast, especially near points and headlands.

Area Forecast Discussion National Weather Service Sacramento CA 241 PM PDT Fri Jul 3 2020

SYNOPSIS. Dry weather with seasonable temperatures for the next week.

DISCUSSION. Long wave troughing is going to continue over the PacNW as we head into the holiday weekend but we will see the SW high push back west a bit. This will bring rising heights to much of NorCal and slightly warmer temperatures. Highs today will be within a few degrees of seasonal normals. Highs tomorrow will warm another 3-7 degrees compared to today.

With the ridge moving back west we will see weaker Delta flow and we are already seeing that this afternoon. Winds will pick up through the Delta this evening but they will not be as strong as yesterday. On Sunday the SW ridge will begin to push back to the east as the PacNW trough slowly begins to push south. This will increase Delta flow on Sunday but when it comes to temperatures they will be similar to Saturday.

-CJM

EXTENDED DISCUSSION (Tuesday THROUGH Friday). Ensembles support general troughing over the PacNW, with some weak embedded waves moving through early next week. This pattern will result in slightly below normal highs and increased onshore flow. Little change in high temperatures is expected next week, with low to mid 90s in the Valley. A few Valley locations might hover around the upper 80s. There are some indications that temperatures might warm up late in the period as the Four Corners high expands. A dry weather pattern will continue.

AVIATION. VFR conditions next 24 hours. Surface winds generally below 12 kts, except for local southwesterly gusts up to 20-25 kts vicinity Delta.

STO WATCHES/WARNINGS/ADVISORIES. None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. 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.
