Area Forecast Discussion
National Weather Service San Francisco Bay Area
820 PM PST Thu Jan 19 2017

.SYNOPSIS...Light rain beginning ahead of the next frontal system
due to move in late tonight and Friday morning. This will bring
another round of wind and rain. Lingering showers Saturday before
the final front brings more wind and rain Sunday. Some residual
showers to persist Sunday night into Monday and possibly Tuesday.

&&

.DISCUSSION...as of 8:20 PM PST Thursday...KMUX radar currently
showing weak echoes moving over the area from the west. Some light
rain is being picked up along the coast. This light rain is in
advance of the next frontal system progged to affect the district
later tonight through Friday morning. Rain is expected to become
moderate to heavy at times overnight and the heavier rain will
gradually diminish from north to south through the day and become
more showery. Thunderstorms will be possible as well with the
increasingly unstable airmass. Rainfall amounts of 1.5-3" for the
North Bay and coastal mountains can be expected, and the lower
elevations and urban areas 0.5-1" is possible. Given all the
recent rains local rivers and streams will be quick to respond,
especially in areas of locally heavy showers or if thunderstorms
develop.

Snow levels are around 4k feet, which isn't expected to change
much through the weekend. Thus, accumulating snow will be possible
over the higher peaks of Monterey/San Benito counties through
Sunday morning. Several inches are possible over the highest peaks
in those counties.

In addition to the rain, southerly winds will ramp up ahead of and
with the frontal passage. Southerly winds of 20 to 30 mph with
gusts 40 to 50 mph possible, with the strongest winds expected
along the coast and in the higher terrain. A wind advisory has
been issued for those areas for late tonight through Friday
morning.

Showers to decrease by Friday night, and scattered showers are
possible on Saturday with a brief break in the shower activity by
Saturday afternoon. The next in a series of storms is then forecast
to move in Saturday night into Sunday. This third system appears
to have the most moisture associated with it...and will likely
have the most rainfall and stronger winds as well. Rainfall
amounts Saturday night into Sunday will be a little higher than
tonight's storm system, especially over the higher terrain of
Santa Cruz and Monterey counties. Hydro concerns are expected to
be greatest with this third system.

Residual showers are expected Monday and possibly Tuesday, then
high pressure is forecast build in over the west to bring a
drying trend to the state.

&&

.AVIATION...As of 3:55 PM PST Thursday...Scattered showers and
isolated thunderstorms with possible lightning and gusty south
winds will continue to impact the region through this evening.
Decreased vsbys possible with moderate to heavy showers. The next
system is anticipated to move in late tonight bringing with it
widespread rain and strong and gusty southerly winds. Wind gusts
are expected to reach 30 to 40 kt overnight. As this system moves
across the region cigs will lower to MVFR around 1500 ft after
06z tonight. The main frontal band is forecast to move through after
12z. Moderate to brief heavy rain showers expected Friday during
the morning rush. IFR cigs/vsbys possible with heaviest showers.
Isolated thunderstorms with small hail possible with this next
system as well. However confidence is low therefore it is not
included in the TAF.

Vicinity of KSFO....Isolated showers will persist through the
evening with mainly MVFR cigs expected. An isolated thunderstorm
cannot be ruled out. South to southwest winds around 10 kt
expected through this evening. Winds will increase late tonight
(around 06z)becoming southeasterly ahead of a cold front.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Isolated showers will persist through the
evening with mainly MVFR/VFR cigs expected. An isolated
thunderstorm cannot be ruled out. South to southwest winds around
10 kt expected through this evening. Winds will increase late
tonight (around 07z-08z)becoming southeasterly ahead of a cold
front.

&&

.MARINE...as of 2:12 PM PST Thursday...Rough and hazardous seas
are forecast to continue through tonight. winds will increase and
turn southerly by late tonight. gale force wind gusts up to 45 kt
are possible ahead of a cold front that will pass through the
waters early tomorrow morning. winds will shift westerly but
remain moderate to gusty...even behind the front. winds will
increase again saturday night as another frontal system
approaches. very large swells arrive friday afternoon with swell
heights building to 25 to 30 feet friday night and saturday. rouge
waves of 30 feet or greater are possible during this timeframe.
