Synopsis A shallow marine layer along the coast with onshore
winds will bring seasonable temperatures to the bay area today.
High pressure begins to strengthen and rebuild over the state this
weekend allowing for inland areas to warm back into the 90s.
Milder conditions will persist near the coast with a shallow
marine layer. The ridge will weaken slightly by Tuesday and
Wednesday as the remnants of tropical storm ivo pass west of the
golden gate. This may bring some increasing clouds and more
humidity to the region.
Discussion As of 1:25 pm pdt Friday... This morning's low
clouds that blanketed coastal portions of the san francisco bay
area and much of the monterey bay area continue to mix-out this
afternoon. With the exception of some stubborn low clouds
lingering around monterey, half moon bay, and around the golden
gate, much of the population across the region can expect mostly
clear skies through the rest of the afternoon. Forecast highs this
afternoon will reach the 60s to 70s along the coast with interior
locations warming to the 80s and 90s, generally falling within
several degrees of late august climatological normals.
Upper level ridge is forecast to build over the next several days,
allowing for a gradual warming trend through the weekend and into
next week for interior locations. High temperatures by Sunday and
Monday will reach the upper 80s to middle 90s for the north bay
mountains and valleys, interior east bay, south bay, as well as
interior monterey and san benito counties. Overall, heat risk for
inland areas will be low to locally moderate, mainly impacting
those sensitive to the heat. Coastal communities can expect to
see continued onshore flow that will keep temperatures in check.
Additionally, the ridge is expected to keep the marine layer
rather shallow, so morning low cloud potential will generally be
limited to the immediate coast and exposed coastal valleys.
Tropical storm ivo, presently positioned several hundred miles sw
of the tip of the baja peninsula, is forecast to move north over
the next several days and weaken as it encounters cooler waters.
Remnant mid high level moisture is expected to advect north to
the golden state by the early to middle part of next week, though|
there remains plenty of uncertainty as to the track. The latest
run of the ECMWF tracks the bulk of the remnant moisture in the
700-500 mb layer offshore. The GFS brings the moisture a bit
closer to our area with increased rhs values as far east as the
sierra. Will have to continue to keep a close eye on the track of
this remnant moisture as this could introduce the possibility of
some isolated thunderstorms for higher elevations in parts of the
state. At a minimum, much of the region can expect increased
mid high clouds, as well as an increase in surface dewpoints with
Aviation As of 10:56 am pdt Friday... Low clouds are quickly
clearing to the coast as a southerly surge of stratus makes a run
northward. Anticipate a return of stratus this evening and tonight
to coastal terminals as the onshore gradient increases. Confidence
is low as to the extent of the stratus intrusion overnight as the
marine layer is expected to remain shallow. Therefore have limited
cigs to mainly coastal terminals. Light onshore winds will ramp
up this afternoon to around 10 to 15 kt.
Vicinity of ksfo...VFR conditions will prevail with ifr MVFR cigs
likely to return after midnight tonight. Low confidence. Light
winds this morning becoming westerly around 15kt after 21z.
Sfo bridge approach... Similar to ksfo.
Monterey bay terminals... Ifr CIGS over kmry will scatter out
between 19z and 20z this afternoon with an early return expected
between 03z-05z this evening. Light winds this morning becoming
westerly 5 to 10kt this afternoon.
Marine As of 9:00 am pdt Friday... Northwest winds will
decrease across the area today but remain breezy over the northern
outer waters. Steep northwesterly swell at 8 to 10 seconds will
decrease today through the weekend with period becoming 7 to 8
seconds. Southwesterly winds are forecast over the near shore
coastal waters this weekend. A moderate southerly swell will
arrive on Sunday and persist through early next week with light
northwesterly swell continuing through the period.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
