Synopsis A gradual warming trend will continue through
Wednesday as high pressure builds over the region. Cooler and
breezy conditions return on Thursday as a cold front sweeps
through the region. While a few light rain showers will be
possible, most locations will remain dry. The ridge will then
rebuild back over the region late in the week resulting in another
warming trend heading into the upcoming weekend.

Discussion As of 01:48 pm pdt Tuesday... High pressure building
over the region has resulted in mostly sunny skies and an uptick
in daytime temperatures compared to yesterday. The ridge aloft
will continue to build and bring even warmer temperatures on
Wednesday with inland areas reaching into the 70s to lower 80s.

Dry weather conditions will also prevail.

By late Wednesday night, the forecast models continue to indicate
a mid/upper level trough will push into the pacific northwest. As
the trough pushes inland, a cold front will drop southward into
northern california and bring the potential for light
precipitation. While the best chances for measurable rainfall will
be to our north, cannot rule out some light rain showers across
the north bay Wednesday night into early Thursday morning. Light
precipitation in the form of showers or sprinkles may drop as far
south as the central coast just before sunrise Thursday morning.

With that said, most locations will remain dry or only see trace
amounts of rainfall from this passing system. Temperatures cool in
wake of the frontal passage with only 60s and lower 70s expected
for Thursday afternoon. Northerly winds will also increase as the
main mid/upper level low slides down into the desert southwest and
the surface pressure gradient tightens along the coast. Breezy
conditions then persist into Friday before the mid/upper level
trough pushes further to the east. May see a few degrees of
warming by Friday afternoon, yet conditions will feel cool given
the breezy northerly winds.

High pressure is forecast to rebuild back across the region late
Friday into the upcoming weekend. As a result, inland areas will
rebound back into the 70s and lower 80s with mostly sunny skies.

Medium range guidance suggest dry weather and seasonably mild
temperatures will persist into early next week as well with the
ridge aloft. While confidence this far out remains low, the models
do hint at the potential return to a wetter pattern late next
week.

Aviation As of 10:33 am pdt Tuesday for 18z tafs. Current vsbl
satellite imagery shows few-sct high clouds over the region.

Expect this to be the case through the day. Biggest story will be
the winds today. West/northwest winds will pick up and become
gusty in the next hour or two. Winds won't be quite as gusty today
as yesterday, but will still gust 20-25 kt, locally higher,
through roughly about 03z (8pm pdt) at most terminals. Threw in a
chance of low clouds for the monterey bay terminals for Wednesday
morning. There could be a couple of hours of stratus around
sunrise, but confidence is low at this time. Overall, moderate to
high confidence with this forecast.

Vicinity of ksfo...VFR conditions anticipated. West to northwest
winds exceeding 20 to 25 kt possible through the evening, possibly
higher at ksfo.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR through the rest of the day. Tafs
reflect MVFR CIGS around sunrise Wednesday morning, but should
lift by 16z, if CIGS develop at all. Gusty west/northwest winds by
21z (2pm pdt) this afternoon, around 20 kt, diminishing around
03z.

Marine As of 08:25 am pdt Tuesday... A long period northwest
swell... 17 to 18 seconds... Will move through the coastal waters
today. Moderate and gusty northwest winds will continue for the
next several days as a strong surface pressure gradient builds
over the region.
