1027 pm pdt Fri apr 20 2018

Synopsis A warming trend and dry weather are forecast through
the upcoming weekend. A weak low pressure system may impact the
region with increased clouds and showers late next week.

Discussion As of 9:00 pm pdt Friday... An upper level ridge
moving over the area brought 5 to 10 degrees of warming over
yesterday. The exception was along the coast south where onshore
flow and patchy low clouds kept temperatures cooler.

Surface high over the eastern pacific will build into the pacific
northwest coast tonight and Saturday bringing a dry light
northerly flow over the area. This will result in a few degrees
of warming in all areas Saturday. High temperatures will
generally be in the mid 60s to low 70s coast and upper 70s to
upper 80s inland.

The ridge will weaken as an upper level trough passes to the
north of the district. This will put a halt to the warming into
early next week.

Medium range models show a cutoff low forming off the california
coast the middle of next week bringing cooler weather and possibly
a few showers.

Aviation As of 10:27 pm pdt Friday...VFR, with mainly clear skies,
will prevail through the overnight with exception of MVFR ifr along
the immediate coastline.

Vicinity of ksfo...VFR. Winds are forecast to diminish after sunset.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Low clouds developing again tonight, but
confidence low regarding timing and coverage. Light onshore winds
overnight.

Marine As of 10:23 pm pdt Friday... Gusty northwest winds will
prevail through the weekend over the coastal waters as high pressure
remains over the eastern pacific. Steep wind waves and fresh swell
will result in hazardous seas likely through the weekend and into
early next week.

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.
