Area Forecast Discussion
National Weather Service San Francisco Bay Area
155 PM PDT Wed Jun 7 2017

.SYNOPSIS...A system to the north will move through our region on
Thursday. Look for rain to accompany the system especially over
the North Bay. The biggest impact around the Bay Area will be mid
to late morning with the main band of rain forecast to be
overhead. Temperatures remain below normal this weekend, then
gradual warming early next week.

&&

.DISCUSSION...as of 2:00 PM PDT Wednesday...All signs still
pointing to a late-season rain event as a system dives down and
moves through our region on Thursday. Today, high level clouds in
advance of it have been streaming into our CWA which has helped to
limit sunshine and also drop temperatures 4 to 8 degrees over the
North and East Bay. Clouds will continue to be on the increase
tonight with the cold front forecast to almost be in Sonoma
County by midnight.

Recent models have been in fairly good agreement and bring the
front into the North Bay tomorrow before sunrise along with much
higher than normal PW values (near 1.3"), then down into the SF
Bay region starting mid to late in the morning. The front will
continue to track to the southeast before falling apart near
Monterey Bay. Although rainfall amounts will be fairly light, for
this time of year decent values can be expected. North Bay
locations will generally range from 2/10" to 1/2" with .05" to
.20" around SF Bay and the Santa Cruz Mountains plus the East Bay
and Santa Clara Valley. For spots farther to the south
accumulations should be less than 0.05". Despite the small
numbers, due to the long stretch of dry weather oils have
collected on the roads conditions could be quite slippery during
the onset of precipitation. Winds will pick up overnight with
breezy southerly winds forecast for the morning. Speeds will
slowly dissipate after the frontal passage.

Behind the front cooler air will work its way into our entire
region with inland spots likely seeing the biggest drops. Highs
both on Thursday and Friday will mostly be in the mid 60s to the
mid 70s. Even locations that are often well into the 80s this time
of year will struggle to get into the 70s. Coastal locations will
likely see minimal if any drops in temperatures and will likely
see much more sunshine due to post-frontal mixing.

An upper level low will then dive down into Eastern
California/Western Nevada on Sunday which will help to bring
another reinforcing shot of cool conditions. Temperatures will
remain cooler than normal through at least Monday. Unlike many
summer days with large temperature gradients, most locations will
be in the mid 60s to the mid 70s.

Temperatures will warm by the middle of week as a weak ridge of
high pressure builds into our region. No signs of additional
systems after tomorrow.

&&

.AVIATION...As of 11:10 AM PDT Wednesday...Gradually improving
ceilings around the area through the morning as marine layer mixes
out/retreats offshore. High clouds will gradually thicken and
lower through the next 24 hours as a cold front approaches the
region. The frontal passage will bring breezy southerly winds,
light rain (especially north of the Golden Gate), and MVFR cigs to
the region. Further south, a return of the marine layer in the
Monterey Bay will bring IFR cigs tonight.

Vicinity of KSFO...VFR through the day. West to southwest winds
to 15 kt with gusts to 22 kt after 20Z. MVFR late tonight with
some early morning light rain possible.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR through midday. Low ceilings return
by 03Z with IFR to LIFR expected overnight. Several cloud decks
expected by sunrise tomorrow as marine layer mixes out ahead of
approaching frontal boundary.

&&

.MARINE...as of 11:05 AM PDT Wednesday...Breezy west winds along
the immediate coast today with lighter winds further offshore. An
approaching frontal boundary will bring increasing south-southwest
winds tonight through early tomorrow morning before weakening by
tomorrow afternoon. Generally light northwest to west seas.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .Tday...SCA...SF Bay from 2 PM
