Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... A large northwest swell has arrived with seas in excess of 15 feet along with larger near shore breaking waves. Low pressure will move inland into the great basin and the central valley on Wednesday. This will result in increasing northwest winds with gale force gusts expected over the northern and outer waters. Gale force winds and large northwest swell will create hazardous conditions through midweek. Moderate wind and seas will persist through the end of the week, particularly in the northern outer waters.

Synopsis Isolated to scattered showers will linger through the
early morning before drier conditions develop this afternoon.

Temperatures will be on the warming trend through the remainder of
the week, yet will remain below seasonal averages. Unseasonably cool
and unsettled conditions continue into the upcoming weekend with a
renewed chance of rain showers as another system drops southward
across the region.

Discussion As of 03:16 am pdt Wednesday... Another active
morning with isolated to scattered showers, especially over the
central coast and coastal waters, as a short-wave disturbance
associated with the mid upper level trough digs southward across
the region. Rainfall amounts during the past 6 hours or so range
from a few hundredths to a tenth of an inch for most areas while
some inland portions of the bay area have remained dry. Meanwhile,
locally heavier rainfall has been reported within heavier showers
with totals during the same period of around one- quarter to one-
half of an inch. While these showers are likely to taper off from
north to south through the early morning, we cannot rule out an
isolated thunderstorm or two over the waters or along the central
coast before completely diminishing. Also of note, profiler data
at point sur indicates a snow level of around 5,200 feet with
chew's ridge surface temperature hold around 33-34 deg f. Thus,
cannot rule out the region's highest peaks seeing some snowfall
early this morning. For the remainder of the day, conditions will
dry out with temperatures warming about 4 to 8 degrees across the
interior compared to yesterday.

In wake of the departing mid upper level low, broad troughing will
persist over much of the western portion of the country through late
week. Being on the west side of the trough, temperatures will warm
slightly yet generally remain below seasonal averages with 60s at
the coast to lower middle 70s inland. May get enough daytime heating
on Thursday for a few showers to develop over interior portions of
the central coast based on short-range guidance. However, widespread
rainfall is unlikely through the remainder of the workweek.

Medium and longer range models indicate additional disturbances
rotating through the western periphery of the through this upcoming
weekend. Thus, look for increased chances of rain showers from late
Saturday into Sunday. With this said, confidence in widespread
rainfall occurring over the region remains low at this time.

Something worth keeping an eye on in the coming days if you have
outdoor plans this upcoming weekend. Regardless, cool and unsettled
conditions are likely to persist heading into early next week given
the unseasonably "troughy" pattern over the region.

Aviation As of 04:57 am pdt Wednesday... Upper low is tracking
to the southeast with showers decreasing in coverage from north to
south. A few showers will be possible at sjc mry and sns early
this morning. Clearing is occurring in the wake of the low but
residual low-level moisture is preventing skies from completely
clearing. Most terminals are expected to experience prevailingVFR
conditions through the morning but occasional MVFR will likely
occur through mid to late morning due to the residual moisture.

Generally west-northwest winds this morning at 5-10 kt will
increase this afternoon to 10-15 kt at most sites. MainlyVFR
conditions expected through the evening hours, with mry most
likely to develop MVFR CIGS by mid evening.

Vicinity of ksfo...VFR expected to prevail with sct at 2000-3000
feet this morning but occasional MVFR CIGS possible through late
morning. Breezy west- northwest winds with gusts to 20 kt expected
to decrease early this morning and then increase once again early
this afternoon with gusts 20-25 kt possible.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Scattered showers near mry possible
through 18z, with decreasing showers near sns through mid
morning. A mix of MVFRVFR expected this morning with clearing
late morning. A return to MVFR CIGS expected around mid evening.

Northwesterly winds of 10-15 kt this afternoon.

Marine As of 03:16 am pdt Wednesday... A large northwest swell
has arrived with seas in excess of 15 feet along with larger near
shore breaking waves. Low pressure will move inland into the great
basin and the central valley on Wednesday. This will result in
increasing northwest winds with gale force gusts expected over the
northern and outer waters. Gale force winds and large northwest
swell will create hazardous conditions through midweek. Moderate
wind and seas will persist through the end of the week,
