Area Forecast Discussion
National Weather Service San Francisco Bay Area
954 AM PST Mon Dec 26 2016

.SYNOPSIS...Mostly sunny conditions will prevail across the
district today, with afternoon highs around the bays in the lower
to mid 50s. Dry conditions are expected to continue through
Thursday, along with a modest warming trend in daytime temperatures.
It will be chilly again tonight, especially in the valleys, then
nighttime temperatures should begin to moderate. Rain chances
start to return around Thursday night.

&&

.DISCUSSION...As of 9:15 AM PST Monday...Skies are mostly clear
across the district, aside from a few thin high clouds passing
through. The upper level low responsible for yesterday's cloudiness
has progressed farther southward offshore, and is now centered
about 300 miles southwest of Pt Conception. The day again got off
to a cold and locally frosty start, with widespread temperatures
down into the upper 20s in the colder valleys. Highs this
afternoon look to be a couple of degrees warmer than yesterday,
mostly in the lower to mid 50s around the bays. Current forecasts
appear on track and no updates are presently anticipated.

Key forecast concern in the shorter term is whether temperatures
in the North Bay Valleys tonight into Tuesday morning will fall
low enough to warrant issuance of a freeze warning. Consensus of
presently available model output and statistical guidance is
right on the edge, so will hold off on deciding until the afternoon
forecast package by which time will have received the rest of this
morning's model runs.

Over the next several days, mostly clear skies will prevail along
with moderating nighttime temperatures and warmer days, as a weak
upper level ridge develops over California. Highs around the bays
are forecast to get back up into the upper 50s to mid 60s range by
midweek as the air mass aloft warms. While the 850 mb temperature
in this morning's 12Z KOAK sounding was right at 0 deg C, good
consensus in latest model output that by 12Z Thursday it will have
increased to around 13 deg C. Up in the hills, especially, this
will result in significant moderation of temperatures; and more
modestly at lower elevations as vertical mixing will be limited.

Towards the end of the week, the upper low now offshore from
southern California is forecast to lift to the northeast and move
inland over southern California. Latest longer range model
solutions differ as to whether and to what degree the northern
portion of the associated precipitation shield will spread into
our area. The new 12Z GFS keeps it just south of our southern
border while the 00Z (latest available) ECMWF brings it farther
north with light precip over the southern half of our CWA by
Friday morning. Will examine further for the afternoon forecast
package.

In the longer range, models basically agree in building a high
amplitude ridge offshore northward into the Gulf of Alaska late in
the week, but differ significantly in the details. In the 12Z GFS
and Canadian model solutions, the first in a series of cold upper
level disturbances moves southward down its eastern periphery and
through our area Friday night. On the other hand, the 00Z (latest
available) ECMWF solution keeps the coldest air to our northeast
and instead undercuts the offshore ridge and brings moist zonal
flow into our area by the beginning of January.

&&

.AVIATION...As of 9:50 AM PST Monday...For 18z tafs. Visible
satellite shows only a few high clouds over the area, as an upper
level low continues to drift southward off the southern California
coast. Expect VFR conditions to continue through the forecast
period. Only concern and question will be winds early this
afternoon. In agreement with the CWSU, current thinking is that
lower level winds may mix down to the surface for a few hours,
especially for Bay Area terminals, though model guidance keeps
winds light. This will be monitored accordingly, and amended if
necessary. East/northeast winds 10-15 kt will be possible.

Vicinity of KSFO...VFR. East/northeast winds around 10 kt,
possibly greater at times. Winds at KSJC may be more northwesterly
this afternoon, albeit light.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR with mid and high clouds with light
winds.

&&

.MARINE...as of 8:30 AM PST Monday...The gusty easterly winds
around the Golden Gate have fallen below small craft advisory
criteria and will continue to subside through the day. The vigorous
low pressure system that now resides off the southern California
coast may continue to generate moderate easterly gusts through
the day. Winds will turn northerly tonight and will remain light
through Thursday as high pressure builds. Winds and wave heights
will begin to pick up on Friday starting in the northern outer
waters as a strong trough approaches the area from the Gulf of
Alaska.

&&

     .Tday...None.
