Synopsis An area of low pressure off of the northern california
coast will maintain seasonably cool temperatures with widespread
night and morning low clouds through Tuesday. Warmer conditions
return for the second half of the week as the upper level ridge
builds back over california. Above averages temperatures are
forecast late in the week and will likely continue into the upcoming
weekend.

Discussion As of 12:58 pm pdt Monday... Temperatures across the
region this afternoon are running a few to as much as 15 degrees
cooler (at the santa rosa asos) compared to yesterday as a
mid upper level trough and associated low pressure system remains
off of the northern california coast. While the fort ord profiler
shows the depth of the marine layer still around 2000 feet, low
clouds have mostly retreated to the coast with sunny conditions
inland and over san francisco. Given the depth of the marine
layer, low clouds will likely push back inland late this evening
and into the valleys overnight, similar to this morning. In
addition, patchy drizzle mist will again be likely along the coast
Tuesday morning. Overall conditions on Tuesday will be similar
today as the weak short-wave trough continues to influence the
region.

The ridge of high pressure over the southwestern portion of the
country is then forecast to build back toward the west coast late in
the week. This will result in a gradual warming trend beginning on
Wednesday and continuing through at least Friday. Inland
temperatures as well as those in the higher elevations will warm
back to above seasonal averages. The marine layer will also likely
become compressed as the ridge aloft builds. Thus, look for less
inland coverage of overnight morning low clouds later in the week.

At this time, the warmest day appears to be on Friday when
widespread 90s are likely during the afternoon hours for inland
areas while weak onshore flow keeps conditions closer to average
near the coast. Cannot rule out a few of the warmest inland spots
briefing exceeding the 100 degree mark on Friday afternoon.

The forecast models put a hold on the warming trend over the weekend
as a mid upper level trough pushes inland across the pacific
northwest. However, still look for temperatures to be above seasonal
averages for most inland areas through the weekend. While there are
some difference in the model solutions late in the period, a further
warming trend looks possible early next week as the ridge
strengthens over the region. With that said, the GFS shows the ridge
a bit further inland with moisture associated with now hurricane
hillary advecting northward toward the california coast early next
week. Thus, still a great deal of uncertainty with regards to the
overall pattern heading into next week. This is still 6 to 7 days
out and will have time to monitor the forecast models in the coming
days.

Aviation As of 10:51 am pdt Monday... Clearing of stratus and fog
is accelerating while the marine layer depth continues to increase.

The marine layer is nearing 2,200 feet deep at the bodega bay and
fort ord profilers.

The 2.6 mb smx-sfo and 2.9 mb sns-sjc pressure gradients are a little
more robust than the NAM is forecasting thus ongoing southerly flow
may hold on a bit longer into this afternoon before the sea-breeze
circulation sets up. A deep, nearly vertically stacked closed low
west of the bay area will remain quasi-stationary through Tuesday,
possibly undergoing a little strengthening and amplification at the
mid-upper levels tonight and Tuesday.

Vicinity of ksfo...VFR through this evening. MVFR cig possibly
returning by 10z Tuesday. Light e-ne wind has developed, and it
may hang on til 21z time-frame before onshore wind returns, low
confidence.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR through this afternoon. CIGS probably
returning this evening though low confidence on timing at this time.

Marine As of 9:33 am pdt Monday... A weak low pressure system
off the california coast will result in light to moderate southerly
flow along the coast. Northerly winds will return midweek as low
pressure moves inland and high pressure builds over the eastern
pacific.

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.
