Synopsis Cloudy conditions today ahead of an incoming dry
upper trough that will bring a cooling trend into Thursday. By
Friday temperatures start to rebound leading to another warming
and drying trend this weekend with some light offshore winds
possible. Dry pattern continues through the middle of next week.

Discussion As of 01:40 pm pst Wednesday... Mid and high level
clouds remained pretty solid through the day ahead of approaching
upper level trough. Latest water vapor imagery puts the trough
near 130w or about 500 miles west of san francisco. The upper
clouds definitely put a damper on any warm up this afternoon.

Additionally, the morning fog was very slow to clear with some
coastal locations not clearing much at all. All of that being
said, decided to lower MAX temps today as many locations would
have fallen short of the forecasted MAX temperatures. San
francisco downtown has remained below 60 degrees as of 1pm.

Definitely a chilly day in the city.

For tonight mid and high level clouds will remain pretty thick
with low clouds moving inland as well. Still cannot rule out
patchy drizzle late tonight early Thursday with additional lift
from the trough. Current forecast will have a mention of coastal
fog drizzle locally inland. Would not be surprised to see a few
bucket tips early Thursday. The trough combined with cloud cover
will lead to another chilly day around the bay area on Thursday.

Temperatures may warm a tad on Friday as the upper trough moves
eastward, but lingering clouds and onshore flow will keep max
temps in check. No real change to the forecast for the upcoming
weekend as high pressure rebuilds over the region. One area of
concern this weekend will be heightened fire weather concerns.

Medium range models continue to show high pressure building into
the great basin with lower pressure along the ca coast by
Saturday. Flow at 2500 feet becomes north to northeast. This set
up will allow for some drying and breezy gusty winds over the n
and E bay higher terrain. Not worthy of a red flag warning, but
something to monitor.

The ridge begins to flatten by early next week as the epac begins
to become more active. The longwave pattern shows a tight low
pressure system moving into the pac NW with a secondary pulse
moving through almost as an inside slider Monday Tuesday.

Interesting to note the ECMWF brings some rain into norcal Monday
night, but other models remain dry including some ensembles. As
the trough progresses eastward models are trending that the trough
deepens enough and becomes a cut-off low over socal by mid- week
with precip. For the bay area, this pattern could mean continued
dry weather and possibly another push of offshore northerly winds.

Aviation As of 04:00 pm pst Wednesday... For 00z tafs. Satellite
shows high clouds streaming across the bay area from the west out
ahead of the next cold front. Low stratus remains hugged along the
coastline with isolated portions in the sf and monterey bays. A
weak trough moves over central california and with it a chance for
light drizzle in the north bay with an increase in low to mid
level moisture overnight tonight into early Thursday morning. This
will bring generally sct-ovc ifr to MVFR CIGS primarily from
02-18z thu. Winds will also shift to become more southerly with
the frontal passage but remain generally light overall.

Vicinity of ksfo... Patchy low clouds are in and around the sf bay,
but shouldn't impact vis, but increasing chances for low level
clouds after 04z thru Thursday morning. By Thursday midday, the low
clouds will lift to mid levels after 16-18z Thu with impacts to
visuals possible through midday Thursday. Winds are currently out
of the northwest, but will shift to become more southerly early
Thursday morning.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Though currentlyVFR, low clouds still
linger over the bay over with fingers of stratus moving to the
salinas valley. Low clouds return by 02z which will persist
through Thursday morning. Winds remain on shore and breezy but are
expected to weaken overnight.

Marine As of 03:37 pm pst Wednesday... Light to moderate
southerly winds will persist through tonight and tomorrow across
the coastal waters. Winds will switch to northwest late on
Thursday night into Friday morning with increasing winds through
the day Friday. A light northwest swell will continue through
Thursday morning. A larger, longer period northwest swell will
arrive Thursday evening and continue through Friday and Saturday.
