Synopsis Deep marine layer with nearly all areas starting the
day cloudy which will keep temperatures on the cool side of normal
today. Saturday will trend back towards seasonable temperatures as
high pressure begins to build. Dry and warmer Sunday and Monday.

Another trough begins to approach by Tuesday and Wednesday with a
modest cooling trend and continued coastal clouds.

Discussion As of 1:43 pm pdt Friday... Overcast skies blanketed
much of central california this morning and early afternoon with
the marine layer exceeding 4000 ft. Visible satellite showed the
cloud cover extending along the central coast and going as far
inland as the san joaquin valley and pushing up against the
southern sierra foothills. The clouds have been slow to erode away
again today; some areas along the coast may not see the sunshine
at all. Temperatures will be relatively cool for interior
locations where today's afternoon highs will range from about 5 to
15 degrees below late may climatological normals.

At the present a trough axis extends from the intermountain west
southwestward through central california. This trough will shift
east into the great plains over the next 24 to 36 hours. Meanwhile
a ridge will amplify off the west coast and will allow for
temperatures to begin an upward trend through the holiday weekend.

Saturday's high temperatures for the interior will range from the
upper 60s to around 80, while locations along the coast will
remain marine-influenced in the mid 50s to mid 60s. Inland areas
will warm by about 2-7 degrees from Saturday to Sunday, and
several additional degrees from Sunday to memorial day. By this
point most inland locations will be within 2-4 degrees of normal.

The exception would be the southern salinas valley and parts of
san benito county where guidance suggests temperatures will reach
the 90s by Sunday. If you have travel plans over the holiday
weekend, we encourage you to visit weather.Gov for the latest
forecast for your travel destination.

From Tuesday to Wednesday the ridge will shift eastward into the
great basin and will allow for temperatures to moderate a bit as a
weak trough moves onshore. 12z ECMWF is trying to paint some very
light QPF over parts of the area on Wednesday, but confidence is
low and will keep pops less than 10 percent at this time.

Looking ahead to the beginning of june, the climate prediction
center's 6 to 10 day temperature outlook (valid june 1 to 5) gives
much of central and northern california an increased chance of
experiencing above normal temperatures.

Aviation As of 4:45 pm pdt Friday... Low clouds have been slow
to clear on Friday afternoon and likely will not clear in some
areas. Expect widespread MVFR conditions in all areas by mid
evening and continuing through late Saturday morning. Weak low
pressure offshore will maintain light southerly winds this
evening. Winds will turn to a more typical west to northwest
direction by Saturday afternoon.

Vicinity of ksfo... MVFR ceilings likely through late Friday
morning, although low clouds may briefly scatter out early in
period.VFR conditions expected to return by 17z Saturday. Light
southwest winds overnight will turn to the west by midday Saturday
and increase Saturday afternoon.

Sfo bridge approach... Similar to terminal.

Monterey bay terminals... MVFR ceilings likely through the period,
although low clouds may scatter out on Saturday afternoon for a
few hours. Light southwest to south winds through early Saturday
morning then becoming light westerly.

Marine As of 08:48 am pdt Friday... Weak high pressure offshore
will result in relatively light winds and small seas along the
central coast. High pressure will increase over the weekend with
increasing winds on Saturday and lasting through the memorial
day.

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.
