Area Forecast Discussion
National Weather Service San Francisco Bay Area
1142 AM PDT Tue Jun 30 2020
.SYNOPSIS...Today's temperatures are expected to be similar to
Monday. Cooling is forecast for Wednesday and Thursday, followed
by warming over the Independence Day weekend. Light to moderate
onshore flow will prevail through the period, along with areas of
night and morning coastal low clouds and fog.
&&
.DISCUSSION...as of 08:29 AM PDT Tuesday...Morning satellite
imagery shows a few remaining patches of stratus just outside the
Golden Gate, but they're thinning rapidly. More widespread
stratus is impacting the Monterey Bay region and points southward
to Pt Conception. The Ft Ord Profiler reveals the stratus layer
is very shallow in nature - only a few hundred feet. The
compressed marine layer is contributing to patchy dense fog.
Automated sensors at Monterey Airport have been as low as 1/8 of
a mile. A quick peek out the window shows the fog is thinning and
sunshine is emerging. For the rest of the morning stratus will
hug portions of the Monterey Peninsula southward through Big Sur.
Elsewhere sunny skies will prevail. If you like yesterday's
weather you'll like today's. Temperatures will be very similar
with highs in the 60/70s at the coast and 80/90s inland or
seasonably cool at the coast and a few above normal inland.
No update is needed...

.PREV DISCUSSION...As of 2:45 AM PDT Tuesday...Winds in the North Bay
Mountains are much lighter earlier this morning compared to
yesterday morning, which is fortunate since relative humidity
values are lower. Although northerly winds in the hills have
diminished, onshore surface pressure gradients remain relatively
weak. Thus we can expect another day of seasonably warm
temperatures inland - similar to yesterday or perhaps a few
degrees warmer in some spots. Little change is forecast near the
coast. Fort Ord profiler data shows the marine layer has
redeveloped, with a depth of about 800 feet. Patchy coastal low
clouds and fog have formed from San Francisco southward and patchy
dense fog is likely near the ocean through at least mid morning.
An upper trough currently centered over the northern Rockies and
Great Basin is forecast to retrograde over the next couple of
days. This will result in a deepening of the marine layer through
Thursday, allowing night and morning low clouds to develop farther
inland, which in turn will bring about a general cooling trend.
Cooling will be enhanced on Thursday by the development of
southerly low level flow. Inland temperatures are forecast to be
about 7 to 10 degrees cooler by Thursday, while coastal temps will
likely cool by only a few degrees.
Models agree that the upper trough will lift northward late in the
work week and into the weekend while an upper ridge over the
Southern Plains and Desert Southwest expands westward. These
synoptic-scale changes will bring about slight warming on Friday,
with more significant warming forecast for Saturday the 4th. Most
warming on Saturday will be confined to inland areas as
persistent onshore flow will keep coastal areas seasonably cool.
Night and morning low clouds and fog will persist in coastal areas
into the holiday weekend. The models diverge slightly on the
temperature forecast by Sunday, with the GFS forecasting a few
more degrees of inland warming while the ECMWF holds temps steady
or cools them by a degree or two. The upshot is that our area can
expect typical summertime weather conditions over the holiday
weekend.

.AVIATION...As of 11:42 AM PDT Tuesday...for 18z TAFs.VFR for all
terminals around the Bay Area and Monterey Bay regions. Some
breezy westerly winds are likely this afternoon, otherwise look
for generally fair conditions through the day. The marine layer
will be back early tonight, but an upper trough dropping into the
region overnight will help to lift the cigs pre sunrise and allow
for better vsby. Regardless, cigs won't fully burn off until mod
morning.
Vicinity of KSFO...VFR through the day. Marine layer to return
overnight with possible low cigs around 800 feet. Any cigs will
return early tonight and should lift early, then scour out by mid
morning.
SFO Bridge Approach...Similar to KSFO.
Monterey Bay Terminals...VFR through the day, but look for the
marine layer to return early tonight. High pressure nosing in from
the south will cause this marine layer to drop cigs low again
tonight, along with vsby. However, an upper trough trying to reach
into the MoCo overnight could help to scour out the marine layer
earlier. Confidence is low on any early scour, but we're watching.
&&
.MARINE...as of 11:32 AM PDT Tuesday...Northwest winds remain
breezy over the waters and will strengthen across the northern and
outer waters on Tuesday. These winds will generate steep fresh
swell resulting in hazardous seas conditions, particularly for
smaller vessels. A shorter period northwest swell and a longer
period southwest swell will keep seas mixed.
