Synopsis Shower chances will continue across the north bay on
Friday and Saturday as the storm track shifts north. A weak
boundary will move into the sf bay on Saturday morning, bringing
a chance of showers for parts of the bay area. Dry conditions are
anticipated from san jose and points south through Saturday. More
widespread light rain is forecast for Sunday as a pacific storm
system moves through the area, bringing along with it the
potential for more strong winds. Dry and mild weather is expected
to develop later on Monday and continue through the remainder of next
week.

Discussion As of 2:27 pm pst Friday... A mixture of clouds and
sun have been observed across the san francisco bay area and
central california coast this Friday afternoon. The bay area and
points north have been generally blanketed by broken overcast
mid high cloud decks, while cirrus cirrostratus clouds have passed
over the skies from monterey southward. As the afternoon
progresses, do expect the cloud coverage to gradually increase
from north to south, but a pleasant january day overall. As of 2
pm, temperatures have already cracked 60 at san jose, oakland
monterey, and salinas, while other major airports are in the
middle to upper 50s.

A surface warm front extending from a low about 500 miles west of
the oregon coast will lift northward through northern california
over the next 24 hours, accompanied by warm air advection in the
mid-levels. This is producing a solid stratiform deck from sonoma
county northward, along with warm frontal precipitation impacting the
humboldt coast. At the present, a rather flat upper level ridge
on top of us is helping to hold down rain chances over our
area... For now. As this ridge shifts eastward over the next 6 to
12 hours, we'll see light rain chances nudge upward across our
area. The latest NAM and hrrr runs introduce scattered showers to
sonoma county after sunset this evening, gradually spreading south
toward the golden gate through the night and into Saturday. Rain
amounts are forecast to remain light with perhaps up to several
tenths of an inch for the north bay mountains. San jose and
locations southward will likely remain dry with less than 15
percent pops over the next day.

By late Sunday, rain chances will become more widespread across
the bay area and central coast as upper level trough and surface
cold front approaches the area. Rain amounts at this point look to
be in the 0.5 to 1 inch range for the north bay mountains, up to
0.5 inch in the north bay valleys and santa cruz mountains, and
less than 0.5 inch elsewhere. Can't rule out some localized areas
in the north bay mountains exceeding an inch. The the primary
impact with this system will be another round of strong gusty
winds that will arrive behind the cold front overnight Sunday and
into Monday morning. The hills as well as coastal locations could
see west to northwest winds in the 20 to 30 mph range with higher
gusts with this event. Will have to closely monitor over the next
day to determine if wind headlines will need to be issued.

Around Tuesday, models begin to advertise a building and highly
amplified upper level ridge over the eastern pacific. This will
allow for several days of dry weather to commence for much of the
golden state through the end of next week.

Aviation As of 9:53 am pst Friday... For 18z tafs. Showers have
ended, but mid-high CIGS remain. A few weak disturbances will pass
through norcal bringing a chance for some showers, but most likely
for the north bay and oak sfo. Winds will be generally light.

Vicinity of ksfo... Light winds and mid level CIGS through this
evening. A few showers may impact the terminals overnight.

Sfo bridge approach... Similar to sfo.

Monterey bay terminals...VFR conditions expected through the
period. Light winds.

Beaches As of 9:57 am pst Friday... Buoys continue to show
moderate-large swell with a moderate period. Breaking waves of 20
to 30 feet are possible today. A high surf warning remains in
effect until 5 pm today. These large breaking waves will lead to
increased wave run- up on beaches with waves topping and washing
over large rocks and jetties. These conditions may also produce
localized coastal flooding of vulnerable locations, especially
early this morning during high tide. Use extreme caution near the
surf zone as these large waves will be capable of sweeping people
into the frigid and turbulent ocean water. Cold water shock may
cause cardiac arrest, and it also can cause an involuntary gasp
reflex causing drowning, even for a good swimmer. The surf zone
will be very dangerous due to strong currents and powerful
breaking waves.

Marine As of 09:51 am pst Friday... Swells will continue
gradually diminish through the day, but still remain hazardous
through this evening. Of greatest concern will be near the
immediate coastline, harbor entrances and the san francisco bar.

Conditions will improve tonight and into the weekend as the
swells continue to diminish.
