Area Forecast Discussion
National Weather Service San Francisco Bay Area
1258 PM PDT Sun May 7 2017

.SYNOPSIS...Aside from a slight chance of showers over interior
portions of the Central Coast this afternoon, dry weather conditions
will prevail region-wide. A warming trend will then continue into
Tuesday as high pressure builds off of the coast. Temperatures cool
by midweek as an upper level trough approaches the Pacific Northwest
and replaces the ridge aloft.

&&

.DISCUSSION...as of 12:57 PM PDT Sunday...Temperatures at this
hour are generally a few to as much as 10 degrees warmer compared
to 24 hours ago under mostly sunny skies. A few/sct clouds persist
over the souther portion of the region however as a mid/upper
level low continues to be centered over southern California. This
system is forecast to gradually shift a bit further south and then
inland during the next 24 to 36 hours as high pressure builds
over the eastern Pacific. Meanwhile, cannot rule out an isolated
shower or two over the hills/mountains of San Benito County
through this afternoon with the proximity of the mid/upper level
low. Overall though, rain chances remain low and the remainder of
the region will continue to experience dry conditions.

As the ridge off shore builds toward the coast, a warming trend will
continue into the start of the work week with inland areas warming
back into the 70s to lower 80s by Monday and more widespread 80s
inland by Tuesday afternoon. With this pattern, boundary layer
moisture will also begin to deepen off the coast and start to spread
inland during the overnight/early morning hours. This will result in
an increased potential for stratus and potentially some patchy fog
the next few nights. By late Tuesday night into Wednesday morning,
the models are hinting at a possible southerly surge that will bring
low clouds and fog up from the southern California coast. With this
and return of a more predominate onshore flow, conditions will cool
region-wide on Wednesday by a few degrees at the coast to around 10
degrees inland. May even see places around the northern Monterey Bay
(Santa Cruz area) be under cloud cover much of the day on Wednesday.

Late in the week, the ridge will continue to flatten and be pushed
southward by and approaching mid/upper level trough. This system is
forecast to approach the Pacific Northwest Thursday into Friday and
drive a weak frontal system southward into northern and central
California. As a result, cannot rule out a slight chance of showers
across the North Bay on Thursday, yet confidence remains low given
limited upper level support and available moisture. Thus, only have a
slight chance mentioned in the official forecast at this time.
Otherwise, the trough aloft is forecast to lingering into late week
and potentially into next weekend which will help keep temperatures
generally below seasonal averages.

&&

.AVIATION...As of 10:56 AM PDT Sunday...Morning satellite shows
the majority of the forecast area clearing as low pressure over
southern Cal slips off to the east-southeast. There remain a few
clouds across the far southern terminals with some developing over
the east Bay hills. For the most part VFR skies and vsby are
expected today. Winds will be the main factor to contend with this
afternoon as the NW flow develops. While not nearly as strong as
Saturday, winds will be gusty this afternoon. With this onshore
push, look for the marine layer to redevelop tonight and in the
early morning hours of Monday. This will bring cigs down in the
typical locations with vsby nudging downward too. With high
pressure building over the area on Monday, any cig and vsby issues
should burn off quickly, by mid morning. Onshore flow will again
bring a pulse of winds on Monday afternoon.

Vicinity of KSFO...VFR. Weak easterly flow will become westerly 15
kt with gusts to about 20 kt after 20Z. A marine layer will
descend upon SFO overnight with limited impacts expected.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...Mix of VFR/MVFR will give way to all VFR
midday. Expect moderate to fresh onshore flow through the
afternoon followed by an increasing marine layer overnight.

&&

.MARINE...as of 09:15 AM PDT Sunday...Conditions will slowly
subside through the day and night as low pressure off the southern
California coast shifts eastward. Despite easing conditions,
steep seas will remain into Monday morning. High pressure will
build off the coast through the first part of the week causing a
resurgence of northerly winds and associated seas.
