area forecast discussion
national weather service san francisco bay area
840 am pdt Fri oct 20 2017

Synopsis Now that shower activity has moved out of the area
dry weather will prevail through the forecast period. Cooler
temperatures and breezy onshore winds will persist today before a
warming trend begins over the weekend and into early next week.

Temperatures are forecast to be well above average through most of
next week.

Discussion As of 8:40 am pdt Friday... Last nights system
quickly moved through with rain beginning in the north bay in the
evening and reaching san francisco by around 11 pm. Rainfall
totals varied across the CWA with areas in the north bay mountains
receiving up to 0.91" at middle peak in marin county to 0.40" in
boulder creek in the santa cruz mountains down to only a few
hundredths of an inch for parts of monterey county and far
eastern inland areas.

Cool temperatures are expected again today with highs forecast in
the upper 50s and 60s for most locations. Along with cool
temperatures, breezy onshore winds will persist throughout the day
reaching 15 to 25 mph in the afternoon, with higher gusts
possible.

The main forecast concern will be the warm temperatures for the
region early next week.

Prev discussion As of 3:05 am pdt Friday... A warming trend
will begin during the weekend as an upper level ridge builds over
the state. Much warmer temperatures are then forecast early in the
work week as the upper ridge strengthens along the west coast and
light offshore flow develops. On Monday and Tuesday expect
widespread high temperatures in the 80s to around 90, with these
warm temperatures developing not only inland, but in coastal areas
as well. Slight cooling is projected late in the week as the
ridge begins to weaken.

Aviation As of 5:10 am pdt Friday... For 12z tafs. Colder and
drier air filter in on the backside of the frontal boundary has
resulted in mostly clear skies with only patches of low clouds
this morning. Temporary CIGS possible between now and sunrise with
rapid clearing expected this morning. Winds anticipated to veer
increasingly to the west with speeds increasing this afternoon to
around 10-15 kt with gusts around 20-25 kt.

Overall forecast confidence: moderate to high
vicinity of ksfo... .MVFR CIGS will scatter out relatively fast
this morning as a drier airmass settles into the region.VFR
conditions expected through the remainder of the forecast period.

West winds will gradually increase to around 15 kt this afternoon
with gust to around 25 kt possible.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR conditions anticipated to persist
through the remainder of the forecast period. Light winds will
veer increasingly to the west with speeds increasing this
afternoon to around 10-15 kt with gusts around 20 kt possible.

Fire weather As of 3:05 am pdt Friday... Rainfall which moved
across the district overnight brought wetting rains to many
locations. Highest rainfall amounts were in the north bay
mountains, but many locations at lower elevations received around
a quarter of an inch. Rainfall should end in most areas by mid
morning. Today will be a cool day with brisk northwest winds.

A warming trend will get underway during the weekend as a high
pressure ridge begins to build over california. This ridge will
strengthen into early next week and result in warm and dry
conditions districtwide from Monday through Wednesday. Will need
to be wary of possible gusty offshore winds in the hills beginning
late in the weekend and continuing into Monday night.

Marine As of 2:37 am pdt Friday... Moderate northwesterly winds
will persist in the wake of a cold front that is passing through
the coastal waters tonight. A long period northwesterly swell
will accompany this system creating hazardous seas for mariners
operating small crafts. Mariners are urged to use extreme caution
if out at sea as hazardous seas are forecast to persist over the
next few days.

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.
