Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... A long period southerly swell will enter the coastal waters this morning and mix with a northwesterly swell into Wednesday morning. Gusty northwesterly winds will be mainly confined to the southern coastal waters early this week and gusty onshore winds will also redevelop over the bays today and again Tuesday afternoon and evening. As high pressure builds over the offshore waters this will result in a general increase in northwesterly winds over all coastal waters from mid to late week.

Synopsis A gradual warming trend is forecast through midweek
with very warm to hot temperatures expected across the interior.

Meanwhile, onshore flow and shallow marine layer will maintain
mild temperatures near the coast. Inland areas are expected to
cool slightly during the second half of the week.

Discussion As of 3:15 am pdt Monday... Marine stratus has been
slow to develop overnight along the coast south of san mateo
county, and low clouds have been even slower to develop inland.

Latest fort ord profiler indicates that the marine layer depth
decreased from about 1500 feet last evening to just over 1000 feet
at the present time. Low clouds will likely become more
widespread along our southern coast prior to sunrise. But given
the decreased depth of the marine layer, there will likely be less
low cloud cover across inland areas this morning compared to
yesterday morning. This should result in slightly warmer
temperatures for most inland areas today. A gradual warming trend
is then expected to continue through midweek, especially inland,
as the center of the upper ridge that dominates the southwestern
u.S. Shifts from new mexico westward towards southern california.

Most model guidance indicate that the warmest days this week will
be Tuesday and Wednesday. Widespread highs in the 90s are
expected for the inland valleys and hills of the san francisco bay
area on those two days, and some of the warmest locations may
reach triple digits. However, the warmest airmass is expected to
be across the southern portion of our forecast area. Specifically,
inland monterey county and much of san benito county are expected
to see highs ranging from the upper 90s to 110. These hot
temperatures will result in increased heat risk, especially in the
hills where overnight temperatures will only cool into the 70s. A
heat advisory remains in effect for the mountains and inland
valleys of monterey and san benito counties from noon Tuesday
through 9 pm Wednesday. Isolated locations in the north bay near
lake berryessa may see high levels of heat risk, but most
locations outside of monterey and san benito counties are not
expected to see heat risks rise above the moderate category.

Model guidance indicates gradual cooling during the second half
of the week as the upper ridge weakens slightly. However, based on
latest forecast temperatures, there may be a need to extend the
heat advisory for inland monterey and san benito counties into
Thursday. Some relief from the heat is expected in all areas by
Friday and Saturday.

Throughout the week, onshore flow is expected to persist, along
with at least a shallow marine layer at the coast. These factors
will keep coastal temperatures mild compared to inland areas. In
transition areas between the coast and the inland valleys hills,
in locations such as the coastal valleys, temperatures will be
sensitive to the depth of the marine layer. A relatively shallow
marine layer during the first half of the week will mean warm
conditions in the coastal valleys. But these areas will likely
cool the most during the second half of the week as the marine
layer deepens.

Aviation As of 4:59 am pdt Monday... Marine stratus and fog are
making a return this morning spreading southward along the coast
and extending into the bay area. Diurnal mixing will help lift
cigs this morning, onshore winds will increase later today likely
bringing stratus and fog back inland this evening. Increasing
700-300 mb layer humidity may cause some mid to high level
cloudiness today and tonight.

Vicinity of ksfo... Stratus patches are nearby, MVFR cig possible
til 17z today. Gusty west winds in the afternoon and early evening.

Sfo bridge approach... Similar to sfo.

Monterey bay terminals... Ifr CIGS until late morning,VFR this
afternoon. Stratus likely returning this evening.

Marine As of 3:04 am pdt Monday... A long period southerly
swell will enter the coastal waters this morning and mix with a
northwesterly swell into Wednesday morning. Gusty northwesterly
winds will be mainly confined to the southern coastal waters early
this week and gusty onshore winds will also redevelop over the
bays today and again Tuesday afternoon and evening. As high
pressure builds over the offshore waters this will result in a
general increase in northwesterly winds over all coastal waters
from mid to late week.
