Synopsis A deep marine layer will prevail through today,
maintaining widespread morning low clouds and cooler than normal
inland temperatures. Warmer temperatures will develop by midweek
and continue through the upcoming weekend as high pressure
rebuilds.

Discussion As of 1:52 pm pdt Monday... The deep marine layer
has prevented the usual mid-day clearing across parts of the san
francisco bay area and central california coast. As of 1 pm pdt,
monterey, san francisco, and oakland airports were all still
reporting overcast skies. While the slow and gradual clearing
trend is expected to continue as the afternoon progresses, some
locations along the immediate pacific coast may not see the sun
shine at all today. The clouds are influencing temperature trends
this afternoon as most airports are running about 2 to 7 degrees
cooler than 24 hours ago. By the time the afternoon concludes,
high temperatures will reach the 60s along the immediate coast and
70s to 80s for inland locations. The low clouds are expected to
return again tonight with the chance of some light drizzle along
the pacific coast.

Synoptically, an upper level ridge presently centered over the
southern plains is forecast to build and broaden westward towards
the desert southwest and baja california over the next several
days. This will result in a gradual compression of the marine
layer by the middle of the week. Additionally, a noticeable
warming trend will take place through at least mid-week with the
most significant day-to-day warm-up occurring from Tuesday to
Wednesday. Low 90s will become increasingly more likely on
Wednesday across some of the region's typical hot spots such as
king city, gilroy, livermore, and even santa rosa. Can't rule out
some rural far-inland locations approaching the upper 90s low
100s, but at this point don't think last the MAX temperatures
achieved last week will be repeated this week for the core
population centers.

Forecast guidance shows an upper level trough approaching the
pacific northwest on Wednesday and Thursday with some
precipitation potential for parts of oregon and washington state.

While the san francisco bay area will be well south of any
precipitation chances, the positioning of this trough will help
prevent additional warming for our region. The current forecast by
late week and into the weekend calls for forecast highs to
generally fall within a several degrees of normal along the coast
with inland locations at or slightly above normal.

As mentioned in the previous overnight discussion, models are
suggesting the potential for an uptick in tropical activity well
to our south along the baja california coast by the weekend and
into early next week. There still remains plenty of uncertainty
this far out, but will have to keep tabs on any development as
northbound moisture transport to parts of the southern california
coast and possibly even the central california coast isn't
completely out of the question by early next week.

Aviation As of 4:56 am pdt Monday... For 00z tafs. The marine
layer remains deep this afternoon having risen to over 3000 ft agl
per the fort ord profiler. Stratus remains in pockets along the
coast and is expected to make an early return to area terminals
this evening. MVFR to ifr CIGS anticipated to prevail through
tonight across most terminals. Moderate and locally gusty onshore
flow will prevail through this evening then gradually ease
overnight.

Vicinity of ksfo... An early return of low clouds is expected this
evening. MVFR CIGS are forecast to return around 04z and persist
through the night. Clearing is anticipated around 18z-19z Tuesday
morning. West winds of around 15 kt with gusts 20-25 kt over ksfo
will gradually ease to under 10 kt overnight.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... MVFR CIGS will persist through the
night. Clearing is anticipated around 18z-20z Tuesday. West winds
of around 10 kt will gradually ease to under 5 kt overnight.

Marine As of 2:13 pm pdt Monday... Generally light to moderate
northwesterly winds will persist over the coastal waters through
mid-week as high pressure off the california coast weakens and a
surface low develops offshore of the pacific northwest. Locally
gusty winds are expected to develop late tonight along the big sur
coast south of point sur. Breezy winds are also forecast for
tomorrow afternoon and evening over the inner coastal waters from
pigeon point to point pinos, over the northern san francisco bay
around the golden gate and through the delta, and over the
monterey bay. Mixed seas will continue with shorter period
northwest waves at around 8 to 10 seconds, a light longer period
west swell, and a light southerly swell.
