Synopsis A few early morning showers can be expected today,
otherwise mostly dry through early Sunday. Rain chances will
return by Sunday afternoon and continue through Sunday night with
a few showers lingering into early Monday. Otherwise, dry and
mild weather is expected from Monday through the remainder of next
week.

Discussion As of 2:25 am pdt Saturday... Latest radar scans
continue to show light showers moving across monterey and san
benito counties, with another batch of showers forming just off
the san mateo county coast an moving to the east-southeast. Expect
this shower activity to gradually taper off as the system exits
to the east, with only a chance of showers into the morning. The
rest of the day should be mostly dry with highs in the upper 50s
to mid 60s.

The dry weather will persist into early Sunday. Then, a
relatively weak weather system is forecast to move across northern
california bringing more light rain to portions of the district
late Sunday and Sunday night. The 00z GFS brings rain into the
north bay counties by late afternoon, then down to northern
monterey county before midnight. The system is progged to quickly
move through to the east and be gone by dawn. The ECMWF lingers
precip over the southern counties a little longer into Monday, but
for the most part, most of Monday should be dry.

High pressure is then forecast to build in over the west by
Tuesday keeping the district dry through the remainder of the
forecast period. There is a slight possibility of a weak system
brushing extreme northern california by Wednesday night/early
Thursday that may bring a slight chance of precipitation, but for
now most of the rainfall should remain to the north.

Aviation As of 05:10 am pdt Saturday... Final residual
scattered showers are moving through the southern half of the
district, and resulting in temporary reductions in ceilings and
visibilities to MVFR and ifr. Development of haze and patches of
fog in the valleys is also now occurring across the forecast area,
in the residual moist boundary layer air mass.VFR conditions look
to return to all but possibly monterey bay area terminals by late
morning. Lower than average confidence.

Vicinity of ksfo... PresentVFR conditions considered likely to
continue throughout the day, but can't completely rule out
possible diminishment of CIGS to MVFR during the morning. Onshore
winds increasing to 15-20 knots latter part of the afternoon.

Sfo bridge approach... Same as ksfo.

Monterey bay terminals... Conditions presently varying rapidly
through the range fromVFR to lifr as final area of showers moves
through. Project MVFR ceilings to generally prevail by around
sunrise, then improving toVFR by late morning to early
afternoon.

Marine As of 03:10 am pdt Saturday... Light winds will prevail
across the waters through tonight, aside from south of pt sur and
over northern monterey bay where they are expected to moderately
strengthen as the day progresses. Then on Sunday, winds over the
northern waters will turn southerly and become somewhat stronger
as a weak cold front approaches.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
