851 am pdt Thu oct 17 2019

Synopsis A weakening frontal boundary pushing through the
central coast this morning brought light rain or coastal drizzle
to areas. Expect cooler, breezy conditions to develop in wake of
the frontal passage this afternoon and continue through Saturday.

A warming and drying trend will begin over the weekend and
continue into next week.

Discussion As of 8:51 am pdt Thursday... Satellite imagery
shows the frontal boundary now has moved through much of the bay
area, and clouds are decreasing from north to south. Rainfall
amounts were light, generally a few hundredths at a handful of
places. Mt. Diablo checked in with 0.08" which was the most noted.

Look for northwest winds to increase by this afternoon and become
locally gusty at times along the coast and in the hills.

Temperatures will also be slightly cooler this afternoon,
especially in the hills and higher elevations where 50s and 60s
will be common. More widespread 60s are likely near the coast with
lower 70s possible in the interior valleys. Very little change is
anticipated on Friday, however it should be less windy.

Another quick-moving weather system will clip the north bay late
Friday night into Saturday morning. This system may produce a brief
period of light rain across mainly the north bay, leaving most of
the remainder of the region dry. As this system moves to the east,
a brief period of dry offshore winds will be possible over the
north bay by late Sunday night into early Monday. However, these
winds are not forecast to be strong. A subtle warming trend is
also expected through the upcoming weekend as high pressure builds
over the eastern pacific.

This high pressure ridge is then progged to rebuild into
california by the middle of next week. This will bring a warming
and drying trend, along with periods of offshore flow. Dry
conditions will also persist through the extended forecast period.

Thus, will need to continue to monitor the potential for fire
weather concerns.

Aviation As of 4:45 am pdt Thursday... Weak frontal passage
currently is bringing a spectrum of MVFR to ifr CIGS across the
bay area. Clearing will be strongly dependent on the movement of
the front, but it should transition toVFR conditions from north
to south through the morning hours. Breezy northwest winds will
develop by midday, lasting through the afternoon.

Vicinity of ksfo... Borderline MVFR ifr CIGS for the morning hours,
becomingVFR by the late morning. Winds will be onshore,
increasing through the day with gusts approaching 25 kt in the
afternoon.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Ifr MVFR CIGS and or vis due to frontal
cloud passage currently. Transition toVFR conditions around
midday. Increasing, breezy onshore winds through the afternoon.

Marine As of 2:33 am pdt Thursday... Moderate northwest winds
will continue over the waters through Friday. A large, northwest
swell will arrive this afternoon with the largest waves occurring
Thursday night and Friday. The northwest swell will persist as the
dominant wave through the weekend, waves will slowly reduce from
their peak heights but will remain at hazard levels for small craft.

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.
