Synopsis An inland cooling trend will persist through Saturday
with periods of night and morning low clouds. A warming trend will
begin on Sunday and continue through next week as high pressure
centered over the four corners area builds westward over
california.

Discussion As of 02:00 pm pdt Friday... Models indicate a weak
upper trough overhead, bringing another day of near to slightly
below temperatures and benign weather. A surface trough with axis
just offshore remains in place, creating southerly winds along the
coast and northwesterly winds offshore. This has resulted in a
well-defined circulation about 40 miles offshore from pt reyes,
evident in the stratus and visible from satellite this afternoon.

Clouds have retreated back to the coast in most locations, with
the exception being around monterey bay where stratus is still
retreating from the coastal plain. Temperatures have warmed into
the 60s to low 70s along the coast, and into the 70s and 80s in
the inland valleys. For tonight, expect clouds to fill back in
across much of the inland valleys. Much of the sf bay shoreline
may see less cloud coverage as southerly flow continues.

An upper ridge centered over the four corners will begin to
strengthen this weekend and will expand northwestward over
california next week. A trough will also move into the eastern
pacific, with onshore flow continuing. The building ridge will
begin a warming trend over inland areas on Sunday which will
continue through next week. Highs by early next week in the inland
valleys will return to the 90s. Temperatures along the coast will
remain moderate due to the persistent sea breeze.

Moisture from the subtropics will begin to rotate around the upper
high next week, especially in the mid levels. At this time the
best chance of any instability and thunderstorms looks to remain
east of our area over the sierra. However, this will need to be
monitored in later forecasts as a shift to the west could increase
the chance of elevated convection and thunderstorms by the middle
of next week.

Aviation As of 10:34 am pdt Friday... For 18z tafs. The marine
layer has deepened to just over 2000 ft agl per the fort ord
profiler as satellite imagery shows stratus slowly eroding over
land.VFR conditions to prevail this afternoon and early evening
before MVFR ifr CIGS are expected to return tonight. At this time
similar coverage is forecast for tonight as was seen into this
morning. Southerly winds this morning will turn onshore by the
afternoon at around 10-15 kt.

Vicinity of ksfo...VFR with southerly winds this morning 10 kt or
less increasing and becoming more west to southwest at around 15
kt after 21z. Patchy low CIGS expected again overnight.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... A deeper marine layer has allowed stratus
to remain around the peninsula and over salinas longer this
morning than yesterday. Expecting stratus to erode over the next
hour or so.VFR conditions to prevail this afternoon before
another early return is forecast for this evening. Ifr to possibly
lifr CIGS overnight. Onshore winds into this evening 10-15 kt with
locally higher gusts down the salinas valley.

Marine As of 08:54 am pdt Friday... Split flow will continue
today and tomorrow with light to moderate northwest winds over the
northern and outer waters and southerly winds along the coast.

Locally gusty northwesterly winds over the northern outer waters
will persist into this evening. Winds along the coast will
gradually shift back out of the west to northwest into Sunday.

Steeper short period wind generated waves continue to dominate the
sea state along with a lighter long period southwest swell.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
