Area Forecast Discussion
National Weather Service San Francisco Bay Area
936 PM PDT SAT SEP 10 2016

.SYNOPSIS...An upper level low will develop over northern
California early next week, resulting in a cooling trend from
Sunday through Tuesday. Warming is then expected during the second
half of next week.

&&

.DISCUSSION...As of 9:00 PM PDT Saturday..A weak upper low
currently centered near the San Luis Obispo County Coast is
drifting slowly to the north this evening. Cyclonic circulation
around this low is drawing mid level moisture westward across the
southern Sierra Nevada and San Joaquin Valley. Isolated thunderstorms
have developed over the southern Sierra near Yosemite this evening
but radar indicates this convective activity is dissipating as it
moves west off the Sierra. Mid level moisture is forecast to
increase over our area overnight, particularly across the southern
San Francisco Bay Area. However, it does not appear that mid level
instability will be sufficient to initiate high-based convection
and so thunderstorm chances are not currently mentioned in the
forecast. In any case, thunderstorms chances are not completely
nil so will continue to monitor radar and lightning detection
networks overnight in the outside chance that convection develops.

Evening water vapor satellite imagery shows an upper trough over
British Columbia, dropping south. The models agree that this upper
trough will continue to dig south over the next few days and form
an upper low over northern California by Monday Night. This
process will begin to affect our weather beginning tomorrow in two
ways. First, it will turn the upper winds over our area from east
to west, which will push the incoming mid-level moisture off to
our east. Second, the deepening trough will trigger an increase in
onshore flow by Sunday afternoon and result in the start of a
cooling trend. That cooling trend will become more robust on
Monday as a much cooler airmass descends south and across our
area. Inland high temperatures by Monday will be as much as 15
degrees cooler compared to Saturday's highs. Initially, the upper
trough will deepen our marine layer and result in more widespread
night and morning clouds. But by late Monday we should see enough
cooling aloft to wipe out the marine inversion and mix out coastal
low clouds. Thus, more sunshine is likely in coastal areas by
Tuesday. The result will be relatively isothermal conditions
across our area on Tuesday with inland temperatures not expected
to be that much warmer than coastal temps.

The cooling trend will end by midweek as the upper low moves off
to our east. Warming is then forecast for the second half of the
week as an upper ridge builds near the West Coast.

&&

.AVIATION...as of 9:36 PM PDT Saturday...Stratus and patchy fog
along the coast with minor inland intrusion this evening, clear
inland. The SFO-SAC pressure gradient is 3.6 mb while the ACV-SFO
is 0.9 mb, thus onshore winds prevailing will usher in stratus and
patchy fog overnight into Sunday morning. Lower level cooling
Sunday will be followed by robust lower level cooling later Sunday
night and Monday and quite likely eroding the marine inversion
early next week.

Vicinity of KSFO...W-NW winds have decreased. IFR cig 11z-17z then
MVFR cig til 21z Sunday. VFR is a good possibility Sunday evening
into Monday.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...IFR tonight and Sunday morning. VFR returning
by late Sunday morning. SCT-BKN MVFR cigs Sunday afternoon with VFR
possible Sunday night into Monday.

&&

.FIRE WEATHER...As of 2:35 PM PDT Saturday...First and foremost,
removed the mention of thunderstorms( see above for details).
Despite the lack of thunderstorms the airmass is unstable and will
remain unstable through early Sunday. As a result, pyro cu will be
possible as seen today on the visible satellite. Mild and dry
conditions will remain above the marine layer until the second
upper low arrives Monday/Tuesday. The second low will bring a
noticeable cooling trend to the Soberanes Fire. Temperatures will
likely be some of the coldest seen in sometime, especially Monday
night through Tuesday night.

&&

.MARINE...as of 9:00 PM PDT Saturday...A weak northerly pressure
gradient will maintain relatively light northwest winds across the
coastal waters. Gusty onshore winds will continue north of the
Bay Bridge and through the Delta this evening with gusty onshore
winds resuming Sunday. Northwest winds will strengthen over the
northern outer waters early next week. A shorter period northwest
swell will mix with a longer period southwest swell through the
weekend.

     .Tngt...SCA...SF Bay until 3 AM
