Area Forecast Discussion
National Weather Service San Francisco Bay Area
144 PM PDT FRI MAY 27 2016

.SYNOPSIS...Warmer temperatures will continue into Saturday as
warm north winds move into the Bay Area. A brief cooling trend is
expected on Sunday as the marine layer pushes well inland again,
then significant warming Memorial Day and Tuesday as warm high
pressure builds. A dry upper level trough may approach later next
week with a cooling trend but no rain in the forecast for the next
7 days.

&& of 1:44 PM PDT Friday...Except for some stratus
over the southern coastal waters, skies have cleared across the
CWA. The Fort Ord profiler indicates that the marine layer depth
has compressed to around 1600 feet. The surface pressure gradients
remain strong northerly with 6.3 mb from ACV to SFO, and 6.8 mb
from SFO to LAS. There is still an onshore gradient as indicated
by 1.4 mb between SFO and SAC. Temperatures across the area are
warmer than yesterday at this time with readings ranging from the
60s at the coast to the 70s and 80s inland. Expect a few more
degrees of warming this afternoon with a few of the warmest inland
locations reaching the lower 90s.

Mainly similar conditions are expected through the weekend with
warmer temperatures on Saturday followed by slight coastal cooling
on Sunday as low clouds spread along the coast and locally inland
once again. Medium range models build an upper level ridge over
the Eastern Pacific by Monday. This ridge is forecast to move
inland by Tuesday bringing warmer temperatures to the area through
at least the middle of next week. Another upper level trough is
forecast to approach the coast late in the week bringing cooler
temperatures and onshore flow, but no rain is expected.

&& of 10:30 AM PDT Friday...Strong NW gradient helped
to clear out the CWA this morning with VFR now at all spots.
Should remain VFR through the forecast period outside of Monterey
Bay. Winds will generally be 260 to 280 with afternoon gusts. High

Vicinity of KSFO...VFR through the period. Winds of 260 to 280
will increase to around 25 kt by 22z. Return of stratus looks
unlikely tonight. High confidence.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR through at least 04Z before MVFR CIGS
likely to move back into KMRY. Return should be a bit later at
KSNS. Winds generally 270 to 290 today with speeds over 10 kt for
the afternoon hours. Moderate to high confidence.

&& of 10:30 AM PDT Friday...A moderate pressure
gradient will lead to continued gusty northwesterly winds through
tonight. Over the memorial day weekend this high pressure center
will gradually weaken. Northwest winds will continue early next
week but are not expected to be quite as gusty.
