Area Forecast Discussion
National Weather Service San Francisco Bay Area
453 AM PDT SAT JUL 2 2016

.SYNOPSIS...A minor cooling trend will continue through the first
half of next week especially for inland locations. Late night and
morning low clouds will give way to mostly sunny conditions each
afternoon.

&&

.DISCUSSION...as of 3:00 AM PDT Saturday...Moderate onshore
gradient combines with a marine layer between 1500 and 2000 feet
has lead to widespread clouds along the coast plus some of the adjacent
valleys. Would expect the coverage of clouds to expand until
sunrise although models keep most of it north of the bay bridge.
Could see a sunny start in southeastern SF with clouds and patchy
fog toward western and northern coastal sections. Temperatures are
forecast to show some cooling inland with values at the coast very
similar to Friday. Look for 60s at the coast with 70s and 80s
inland. May see some lower 90s in northern Napa and Sonoma
counties.

Additional cooling is forecast for inland spots for Sunday
through Tuesday as a persistent onshore flow sets up at the
surface while an upper level low and shortwave trof progress
west-to-east from the PacNW to the Northern Rockies. Highs for the
Fourth (Monday) will drop an additional 3 to 5 degrees for the
North Bay compared to today. That translates to a 12 to 18 degree
drop for many spots in that area from the hot readings we had
earlier in the week.

Right now the rest of next week appears very quiet with
comfortable temperatures and no chance of showers in the San
Francisco and Monterey Bay Region.

&&

.AVIATION...as of 4:45 AM PDT Saturday...Latest satellite image
shows low clouds are starting to spread out over the SFO Bay
Area. Fort Ord Profiler showing a deeper marine layer of near 2000
feet. As a result MVFR/IFR cigs are expected at SFO between 13Z
and 17Z.

Vicinity of KSFO...MVFR/IFR cigs expected 13-17z with bkn-ovc008-010.
West wind to15-18 kt after 20z.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...IFR cigs through 19z.

&&

.MARINE...as of 4:45 AM PDT Saturday...High pressure centered 700
miles west of Point Arena will drift slowly northward. This will
confine the strong northwest winds to the northern outer waters
through the holiday weekend. Winds will be lighter over the
southern and inner waters.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .Tday...SCA...Pt Arena to Pigeon Pt 10-60 nm
             SCA...SF Bay from 11 AM
             SCA...Pigeon Pt to Pt Piedras Blancas 10-60 nm
