Area Forecast Discussion
National Weather Service San Francisco Bay Area
855 AM PDT Mon Jun 19 2017

...Very warm to hot conditions to continue inland through
Thursday...

.SYNOPSIS...Slight cooling is expected over the next few days,
mainly in coastal areas and around San Francisco Bay, but cooling
won't be sufficient to mitigate heat risks for areas away from the
coast. In general, very warm to hot conditions will continue
through Thursday. A heat advisory continues in effect for most
inland areas through Thursday. Cooling is then expected from
Friday into the upcoming weekend.

&&

.DISCUSSION...As of 8:55 AM PDT Monday...Although another very
warm to hot day can be expected for inland locations today, in
general temperatures will be 2 to 5 degrees cooler compared to
yesterday. 24 hour change product verifies that with almost all
spots starting out a little lower than yesterday. Last night did
feature some overnight convection, however instability has now
shifted out of the CWA, so no additional cells are forecast.

Latest guidance in is very close to previous run, so will likely
make very little adjustment to forecast high today unless clouds
advance past the coast or winds shift quicker leading to a more
substantial drop in temps.

Will take a close look at Wednesday into Thursday due to current
model disagreement which will have implications on temperatures
and winds.

.PREVIOUS DISCUSSION...Southeast flow aloft late yesterday
carried moisture from afternoon thunderstorms over the southern
Sierra to the northwest and across the East Bay. Meanwhile, a
disturbance rotating around a weak upper level low off the central
California coast interacted with this moisture, resulting in the
development of isolated showers and thunderstorms over the East
Bay around midnight. These showers and thunderstorms then tracked
quickly to the northwest and over the North Bay in the early
morning hours. Several reports of lightning, thunder, and brief
heavy rain were reported between midnight and 2 AM, mainly in the
East Bay. Radar currently shows that convective activity has since
subsided with just a few showers currently located over the North
Bay. The instability and moisture that has triggered this
convective precipitation is expected to move to the north of our
area by sunrise and all shower/thunderstorm activity should end by
then.

Surface high pressure to our north and east has weakened since
early yesterday and pressure gradients have trended from offshore
towards onshore. Satellite reveals that low clouds and fog
offshore are gradually approaching the coast. Also, the upper
ridge that dominates the southwestern portion of the country will
weaken a bit over California the next few days as an upper trough
moves through the Pacific Northwest. These trends point towards
slightly cooler temperatures today and Tuesday, especially near
the coast and around San Francisco Bay. However, the airmass aloft
is forecast to warm a bit further today and the marine layer will
remain too shallow to have much impact beyond the coastal
valleys. Thus, inland areas will remain hot with little, if any,
cooling expected in the valleys and hills away from the coast. The
heat advisory for our inland areas remains in effect through
Thursday.

By Wednesday look for temperatures to begin to trend higher once
again as the upper ridge begins to strengthen just offshore and
onshore flow weakens. The GFS forecasts the development of
offshore flow by Thursday which would mean not only continued
warming inland, but increases in temperatures near the coast as
well. In fact, the GFS solution may mean temperatures on Thursday
may be similar to the widespread hot temperatures our area saw on
Sunday. However, the ECMWF does not develop offshore flow on
Thursday and instead shows a trend towards slightly cooler
temperatures. Have elected to go with a compromise between these
two models and have forecast warming for Thursday, but not by as
much as the GFS indicates. In any case, it appears likely that
very warm to hot conditions will continue inland through Thursday.
If subsequent model runs show offshore flow developing by
Thursday, then we may need to consider expanding the heat advisory
into coastal areas for that day.

One other item for concern is the possibility of locally gusty
northerly winds in the hills on Wednesday night and Thursday if
offshore flow develops according to the GFS. May need to consider
a fire weather watch for the North Bay Mountains starting
Wednesday night if it continues to look as though these offshore
winds may develop.

The models are in general agreement in forecasting a cooling trend
from Friday into next weekend, with temperatures cooling back to
near normal by late in the weekend.

&&

.AVIATION...As of 4:55 AM PDT Monday...For 12Z TAFs. Mostly clear
skies will continue through the forecast period. Coastal stratus
just off the coast will stay confined to the coast due to a
shallow marine layer. Patchy low clouds may bring cigs to Monterey
Bay terminals around sunrise. Confidence is low.

Vicinity of KSFO...VFR conditions expected through the forecast
period. Light winds.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR expected through early morning with a
chance of LIFR conditions between 12z-16z this morning.
Confidence is low. Light winds.
