Synopsis Slightly cooler temperatures are expected once again
on Thursday. Winds shift to the north on Friday and Saturday which
will allow for slightly warmer temperatures leading into the
weekend. These northerly winds have the potential to be gusty
particularly in the north bay hills Friday and Saturday mornings.

Discussion As of 08:03 pm pdt Wednesday... The marine layer is
trickling into low lying valleys this evening as it compresses
down to a modest 1000ft agl. It will retreat once again to the
coastline tomorrow afternoon. The eastern pacific ridge is
expected to continue to erode as a trough descends from the
pacific northwest tomorrow and into Friday. The bay area will
remain on the west side of the trough which will keep skies mostly
clear, providing plenty of sunshine and drier conditions. This
trough will bring northerly winds that will be gusty, 30 mph or
more, particularly in higher elevations of the north bay on
Friday and Saturday morning. These downsloping winds will help
bring warmer temperatures to the bay area Friday and into the
weekend. Extended models are showing the return of onshore flow
and a deeper marine layer early next week which will in turn bring
cooler temperatures.

Prev discussion As of 1:48 pm pdt Wednesday... Satellite imagery
shows low clouds have mostly cleared to the coast across the
district. There is still some stratus around the monterey bay,
near half moon bay, over portions of san francisco, and along the
sonoma county coast. Current temperature readings are running
cooler than yesterday at this time with 60s to lower 80s being
reported at area airports. Locations in the southern interior have
warmed into the upper 80s and lower 90s. The marine layer has
increased to around 2000 feet as of noon, and the onshore surface
pressure gradient is a healthy 2.9 mb, so expect low clouds to
spread inland again overnight.

An upper level low dropping south from western canada into the
pacific northwest will aid in continued cooling over the next
couple of days. Thursday will be the coolest day as an upper level
disturbance moves south across nevada with the trough axis moving
through our district. This disturbance will tighten an offshore
surface pressure gradient with north to northeast winds increasing
Thursday night as this trough moves through. The latest run of
the nam12 model still shows 925 mb winds in the 25 to 35 kt
range... Strongest over the higher terrain in napa county. After
weakening during the day Friday the north to northeast winds will
ramp up once again Friday night, although weaker than Thursday
night. Currently there are no watches or advisories for the north
and east bay hills but will continue to monitor.

Longer range models indicate a long-wave upper trough over the
eastern pacific, with high pressure over the rocky mountain
states. This will maintain cool to near seasonally normal temps
next week.

Aviation As of 04:32 pm pdt Wednesday... For 00z tafs. The
marine layer remains at around 2000 ft agl per the fort ord
profiler. Satellite imagery shows stratus along the coast and
beginning to move inland. MVFR to ifr conditions forecast to
prevail for most sites by this evening with earlier return times
forecast for kmry and ksns. All TAF sites are expected to see MVFR
to ifr conditions by sunrise tomorrow. Low confidence on exact
timing of returns. Breezy onshore winds will continue this
afternoon at around 10-15 kt with higher gusts around the sf bay
area TAF sites. Winds will diminish overnight before onshore winds
increase once again tomorrow afternoon.

Vicinity of ksfo...VFR conditions this afternoon before stratus
moves in this evening. Low clouds may move in tonight earlier than
was observed yesterday evening. Low confidence on timing of return
and tomorrow's clearing. MVFR ifr CIGS to prevail overnight and
tomorrow morning. Onshore winds around 15 kt with gusts to around
20 kt will continue into the early evening before winds diminish
overnight.

Sfo bridge approach... Similar to sfo.

Monterey bay terminals... Thus far, it looks like similar
conditions as yesterday with satellite showing stratus beginning
to move inland towards ksns before eventually wrapping around to
kmry. MVFR to ifr conditions expected over the next few hours.

MVFR ifr CIGS overnight with lifr possible late tonight at kmry.

Right now looks like another late clearing for tomorrow with some
guidance showing low clouds sticking around all day.

Marine As of 02:46 pm pdt Wednesday... Light southerly winds
will continue along the coast south of point reyes through
Thursday, while gusty northerly winds increase over the northern
outer waters tonight. Winds will reach gale force at times in the
outer waters north of point reyes from this evening through at
least Thursday night. Gusty northerly winds will become more
widespread across the coastal waters Thursday through Friday. This
will result in steep fresh swell creating hazardous seas
conditions, particularly for smaller vessels.
