Area Forecast Discussion
National Weather Service San Francisco Bay Area
220 PM PST Sat Jan 21 2017

.SYNOPSIS...Another potent storm system is due to arrive late
tonight into Sunday. This system will result in widespread heavy
rainfall and strong to very strong winds that will likely result
in downed trees and isolated power outages. Flooding of small
creeks and urban areas is also likely. In wake of the frontal
passage Sunday morning, lingering showers will be possible through
Tuesday before drying conditions return later in the week.

&&

.DISCUSSION...as of 2:20 PM PST Saturday...Showers are starting to
decrease across the CWA now, but the next storm system is getting
ready to bear down on the state later tonight and Sunday. The
front extending from an upper low now located west of Seattle,
will quickly approach the west coast this evening. Light rain is
expected to begin early in the evening becoming steadily heavier
with the frontal passage after midnight. In addition to the heavy
rain, winds will increase ahead of the cold front. Computer models
still project winds at the 925 mb level to reach into the 50-60
KT range, which will likely result in strong to very strong winds
with gusts in the 60-70 MPH range along the coast and in the
higher elevations. As a result, a High Wind Warning is in effect
for those areas while inland valley locations are under a Wind
Advisory from late tonight into Sunday morning. The strongest
winds will impact locations just ahead of and along with the frontal
passage. Widespread downed trees and sporadic power outages will
be likely as soils are saturated from copious rainfall over the
past few weeks and it won't take much to take trees down.

Rain will increase in coverage and intensity late tonight and
into the overnight hours. In addition, the strong southerly winds
will help enhance orographic effects along the south/southwest
facing slopes, thus these areas will likely see the greatest
rainfall accumulations from this system. Overall 2 to 5 inches
are likely in the higher terrain with upwards of 6 inches
possible in orographically favored areas, especially in the Santa
Cruz Mountains and along the coastal ranges of Monterey County
through Tuesday morning. Urban areas can expect to pick up another
1 to 2 inches total. There will likely be some rain shadowing
early due to the strong southerly flow limiting rainfall
amounts in portions of the region such as the Santa Clara Valley,
Salinas Valley and even portions of the Monterey Peninsula. The
additional rainfall and potential locally heavy rainfall at times
will result in an increased threat for flash flooding, flooding of
area streams and urban areas. Thus, a Flash Flood Watch remains in
effect through Sunday afternoon.

Winds will diminish after sunrise Sunday morning after frontal
passage, with showers likely to persist across the district.
Conditions will also become more unstable Sunday afternoon and
evening which would result in the potential for embedded
thunderstorms, with this possibility extending into Monday.
Latest thinking is that showers will persist over the region into
Monday night if not early Tuesday morning as an upper level low
slides southward down the West Coast through the unstable
environment.

By Tuesday afternoon, the broad upper level trough will move to
the east while a ridge of high pressure builds over the eastern
Pacific. This will finally allow for drying conditions to return
to the area from Tuesday through the extended forecast period. It
is worth noting that the ECMWF is still hinting at a weak system
moving into the Pacific Northwest Coast Wednesday into Thursday.
Hopefully the ridge is strong enough to keep showers to the
north, however, in a rainy pattern, it doesn't take much. For now,
left pops out for this time frame.

&&

.AVIATION...As of 9:50 AM PST Saturday...For 18z tafs. Scattered
showers today with more steady widespread rain by this
afternoon/evening. VFR/MVFR conditions expected today with
MVFR tonight and locally IFR during heavy rain. SE winds will
quickly strengthen this afternoon and overnight ahead of the
approaching front. LLWS remains in the tafs beginning at about 9
PM tonight and lasting through early tomorrow morning.

Vicinity of KSFO....VFR/MVFR and off/on showers today then steady rain
later today. Increasing winds throughout the day with strong low
level wind shear ahead of the front late tonight into tomorrow
morning. Thunderstorms in the vicinity are possible Sunday
afternoon and night.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR/MVFR and off/on showers today then
steady rain later today. IFR conditions possible during periods of
heavier rain. Increasing winds throughout the day with LLWS ahead
of the front tonight. Thunderstorms in the vicinity are possible
Sunday afternoon and night.

&&

.MARINE...as of 8:31 AM PST Saturday...Expect scattered showers
throughout the day before steady moderate to heavy rains begin
this evening as a fast moving cold front approaches from the west.
Storm force winds over much of the coastal waters are expected
tonight prior to the arrival of the cold front. Occasional storm
force gusts are also possible from San Pablo Bay to the Delta
very late tonight and Sunday morning. Showers and thunderstorms
are expected Sunday night into Monday. Very large and dangerous westerly
swell will persist through Sunday morning. ALthough swell will
begin to decrease Sunday, waves up to 20 feet are still possible
across the waters.
