Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Northwest winds will continue to diminish across the coastal waters through tonight with strongest winds remaining over the northern outer waters. Steep, short period northwesterly swells will also diminish tonight and through the weekend with period becoming 7 to 8 seconds. Southwesterly winds are forecast over the near shore coastal waters this weekend. A moderate southerly swell will arrive on Sunday and persist through early next week with light northwesterly swell continuing through the period.

Synopsis Little change is forecast through the first half of
the weekend. A modest warming trend is then expected from Sunday
into Monday as high pressure strengthens over california. The
ridge will weaken slightly by Tuesday and Wednesday as the
remnants of tropical storm ivo pass west of the golden gate. Ivo
remnants may bring increasing mid and high clouds and more
humidity to the region next week.

Discussion As of 8:55 pm pdt Friday... The combination of a
deeper marine layer and southerly low level flow resulted in
cooling across most of our region today. Today's cooling was most
pronounced in the north bay valleys where south winds enhanced the
inland transport of marine air. Highs in the north bay valleys
today were as much as 15 degrees cooler than yesterday. Similarly,
santa cruz on the north side of monterey bay cooled by 11
degrees. By contrast, today's high of 80 in monterey was 10
degrees warmer than yesterday due to downslope flow off the santa
lucia mountains to the south.

An upper level ridge currently dominates the eastern pacific
between 30 and 40 degrees north latitude, and extends eastward
across california. The models agree that the ridge will gradually
strengthen over california through the weekend and into the early
part of next week. However, warming due to the strengthening ridge
will likely be tempered over the weekend by continued southerly
low level flow. In fact, most model guidance indicates little
change in temperatures on Saturday. Modest warming is then likely
on Sunday and especially Monday as the marine layer compresses
and southerly flow tapers off and gradually veers more to the west
and northwest. Even with the expected warming on Sunday and
Monday, heat risk is projected to only rise into the moderate
category across our inland areas, with just a few pockets of high
heat risk expected in the inland hills where temperatures will
remain warm during the overnight hours. Persistent onshore flow
will keep heat risk mostly in the low category in coastal areas.

The upper ridge axis is forecast to shift to our east by Tuesday
as remnants of tropical storm ivo drift north offshore. There
remains quite a bit of uncertainty as to the exact trajectory of
ivo's moisture, but current model consensus indicates that the
bulk of the moisture will remain offshore from the bay area as it
drifts north, and then shift eastward and inland across northwest
california sometime between Tuesday afternoon and Wednesday
morning. The 12z ECMWF forecasts some of this mid upper level
moisture clipping at least the northern half of our forecast area
late Tuesday. Will need to continue to monitor this situation
closely as high-based thunderstorms and dry lightning are possible
in conjunction with this tropical moisture.

A gradual cooling trend is forecast during the second half of next
week as the upper ridge continues to drift slowly to our east.

Aviation As of 5:46 pm pdt Friday... Plenty of momentum and
kick to a southerly surge driven by a recently strong smx-sfo
pressure gradient. Visible satellite imagery of the coastal
stratus shows a turbulent flow along the boundary of south and
north winds and coastal terrain influences and lower level
turbulence is extending inland; 925 mb south winds ease tonight
but resume to gusty again Saturday, 850 mb south winds hold steady
tonight and Saturday based on WRF output. It'sVFR except areas
of coastal stratus resulting in ifr-MVFR ceilings from kwvi
northward to the sonoma county coast. Gusty onshore winds with
stratus reaching the east bay. Locally strong and gusty wind near
sausalito near 40 mph, a few reports of wind gusts nearing a
similar strength in san francisco. All in all, potential is there
for areas of low level wind shear extending into the mid evening
hours, will amend tafs as needed.

Surface winds mostly easing by late evening the exception to this
is lingering gusty winds from the golden gate and over the san
francisco bay. Stratus and fog will redevelop with some inland
extent tonight and Saturday morning. Ceilings then lift back to
vfr Saturday with potentially additional areas of low level wind
shear nearest the coast.

Vicinity of ksfo...VFR conditions will prevail with ifr MVFR cigs
likely to return after midnight tonight. Low confidence.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR then ifr ceilings tonight and Saturday
morning.VFR returning by late morning Saturday.

Marine As of 4:53 pm pdt Friday... Northwest winds will
continue to diminish across the coastal waters through tonight
with strongest winds remaining over the northern outer waters.

Steep, short period northwesterly swells will also diminish
tonight and through the weekend with period becoming 7 to 8
seconds. Southwesterly winds are forecast over the near shore
coastal waters this weekend. A moderate southerly swell will
arrive on Sunday and persist through early next week with light
northwesterly swell continuing through the period.
