Area Forecast Discussion
National Weather Service San Francisco Bay Area
243 AM PST Mon Jan 9 2017

.SYNOPSIS...A few showers will remains across our area today.
However, the break will be short as rain returns to the North Bay
this evening and then to our entire region on Tuesday as another
system moves through. Rain will change over to showers on
Wednesday with drier weather likely by the end of the week.

&&

.DISCUSSION...as of 3:00 AM PST Monday...The storm that brought
widespread rainfall to our region over the weekend plus strong
southerly winds has mostly exited. Right now KMUX radar shows the
remaining showers over the southern half of our CWA and the trend
over the past 90 minutes has been for lowering DBZs. Models all
remain in good agreement that the southerly progression will
continue with this band out of our area by mid-morning. However,
guidance does show some residuals showers popping up throughout
the day. Those amount will be light, but could catch people off
guard.

The break in the action will be very short as a system moves to
the coast by Tuesday evening or night. In advance of the system precipitation
will stream into the North Bay by this afternoon or early evening
and progress to the south tonight. Rainfall amounts from this
initial push will range from up to 1" in the North Bay down to
1/10" - 1/4" for most urban spots around San Francisco Bay.

As the system nears the coast later tomorrow rainfall will
increase both in coverage and intensity along with southerly
winds. Compared to the storm that just went through, the one on
Tuesday has lower PW and IVT values which will help to lessen the
potential for excess rainfall. However, models bring moderate to
locally heavy precipitation through Tuesday afternoon through the
evening suggesting the evening commute could be quite
challenging. Rainfall amounts are forecast to range from 2 to 4
inches for the North Bay and coastal ranges, 1 to 2 inches for
most urban locations around San Francisco Bay with lesser amounts
for most other spots. Convective parameters also become more
favorable for Tuesday evening/night so added a slight chance for
thunder to the forecast. Rain will change over to showers going
into Wednesday evening with drier conditions forecast by late
Wednesday night.

At the same time, 925 MB speeds look very impressive with 45 to
55 KTs noted. Therefore, a high wind watch will be issued
centered around the North Bay and San Francisco Bay highlighting
local wind gusts in the 40 to 60 mph range. Due to very wet soils
downed trees and power lines can be expected.

Drier weather will return for our entire CWA Thursday through the
weekend giving our region several heavily needed days to let local
creeks/streams/rivers time to recede.

&&

.AVIATION...As of 10:30 PM PST Sunday... Abundant low level
moisture will keep the chance for MVFR cigs tonight. Otherwise
the rain is quieting down with just a few showers passing through
tonight. Winds remain south to southwest.

Vicinity of KSFO....MVFR cigs with a few showers through 10Z.
Cigs rising into VFR category after 10Z with showers gradually
ending. Southwest winds around 15 kt with gusts to 20 kt through
Monday.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...Shower activity has moved out of the
area. Abundant low level moisture will keep MVFR cigs through 15Z
overnight. Cigs lifting into VFR category after 15Z.

&&

.MARINE...as of 10:30 PM PST Sunday...Low pressure off the
pacific northwest and high pressure off the southern California
coast will keep moderate southwesterly winds through most of the
week. Winds will increase tuesday as another low deepens off the
northern California coast.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .Tday...Flash Flood Watch...Big Sur and Santa Lucia area.
             SCA...Pt Arena to Pigeon Pt 10-60 nm from 9 AM
