950 pm pst Tue nov 12 2019

Synopsis High clouds spilling over the ridge of high pressure
that is currently in place will continue to increase overnight.

The ridge will weaken slightly Wednesday with a few degrees of
cooling. Further cooling is expected Thursday as an upper trough
passes through with a return of cooler onshore breezes and some
drizzle for the coastal slopes. The ridge will rebuild over the
weekend with a return of seasonably warm and dry weather. Some
hints for a more active pattern in the extended but no clear
signal for when rain will return to the forecast.

Discussion As of 9:15 pm pst Tuesday... Temperatures finished
off similar to or slightly cooler than yesterday across the region
today. Mainly upper 60s along the coast, low to mid 70s inland
and upper 70s to low 80s across the warmer interior valley
locations. A handful of locations reached into the mid to upper
80s in the warmest southern interior valleys. Temperatures today
were running 5 to 15 degrees above seasonal normals. Oakland
international airport tied its one day record of 72 degrees this
afternoon, a record that was previously set back in 2016. This is
the second day in a row that oakland international airport has
tied it record.

High clouds moving in ahead of the approaching upper trough will
continue to stream across the region tonight. At the surface low
clouds and fog are once again hugging the coast. The slight
difference tonight is a slightly deeper marine layer. The fort ord
profiler is currently displaying a 1500 ft marine layer. Coastal
stratus visible on satellite imagery has already infiltrated down
the length of the salinas valley. Patchy dense fog will remain
possible along the coast. Half moon bay, watsonville and the monterey
airport is currently reporting less than 1 mile of visibility.

Forecast remains on track... No updates at this time.

From previous discussion... The ridge of high pressure currently
overhead will slowly move eastward over the next 12-24 hours
leading to increased onshore flow and a cooler airmass. Forecast
high temperatures on Wednesday will drop 3 to 5 degrees from
today. As the ridge moves east an upstream upper trough will
continue to advance eastward as well. The trough passage is still
on track for Thursday into Friday. The passing trough will bring
widespread cooling the region on Thursday continuing into Friday.

Temperatures by Thursday will be close to or slightly below climo
for this time of year. As noted on the previous discussion the
lingering low level moisture combine with added lift from the
trough may be enough to cause some light drizzle early Thursday.

Some of the 12z models even generate some light precip during this
timeframe with possibly a hundredth or two.

As the trough exits on Friday high pressure begins to rebuild
over the region for the upcoming weekend. Medium range models
even develop another round of offshore flow - similar to what we
just experienced.

The following snippet from the previous discussion still holds
though. Increasing confidence that more jet energy will break the
ridge down with the pattern showing signs of becoming more
progressive by the middle of next week and towards the second half
of the month.

Aviation As of 9:49 pm pst Tuesday... For 06z tafs. Low clouds
have returned to the vicinity of monterey bay while the rest of
the bay area sees a continual streaming of northwesterly high
clouds withVFR conditions. Broadly speaking, winds remain light.

Cigs will lower around the bay area overnight, but not expecting
major impacts.VFR conditions will be expected during the day
Wednesday with locally breezier winds in the afternoon.

Vicinity of ksfo... Winds remain out of the northwest and breezy,
but that is forecast to taper off in the next few hours. High
clouds will remain overnight with few clouds around 500 ft
possible tomorrow morning, though not expecting to impact vis.

Vfr Wednesday afternoon as winds become NW and breezy.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Patchy low clouds remain near the
monterey bay and are forecast to continue through the night,
especially between 04-08z. Winds will remain light overnight
before picking up Wednesday during the day and returning to the
west-northwest.

Marine As of 09:35 pm pst Tuesday... Moderately light winds
shift toward the south by mid morning. By the afternoon, locally
breezy southerly winds are forecast along the coast. Winds switch
back to a wnw pattern late on Thursday night into Friday morning.

Swells out of the northwest continue Wednesday, before a moderate
to locally large longer period northwest swell arrives late on
Thursday.

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.
