AREA FORECAST DISCUSSION
National Weather Service Eureka CA
324 PM PST Tue Dec 10 2024

.SYNOPSIS...Calm and dry weather will come to an end as a cold front
approaches the area Wednesday. Moderate winds and rain will cross
the area through early Thursday morning. A stronger and longer lived
system will hit the area Friday into the weekend.

&&

.DISCUSSION...High pressure remains over the area today but is
finally showing clear signs of breaking down. Though today was yet
another cold and clear morning, even along the coast, thick high and
some midlevel clouds have streamed in across the area today. These
clouds will aid in warmer temperatures tonight with most interior
valleys expected to stay not much colder than freezing. Strong
inversions will likely remain in place at least one more night,
keeping surface conditions very dry with ridgetop dewpoints
currently in the single digits.

Conditions will continue to change as well defined cold front
approaches the area tomorrow. Southerly wind will increase ahead of
the front with most likely beak gusts of 25 to 35 mph along exposed
ridges in headlands. Southerly wind alongside currently dry air will
most likely promote promote pronounced rain shadows. Though rain may
start as soon as tomorrow afternoon in well aligned location such as
the King Range and northern Mendocino County, wetting rain is
unlikely to begin in low elevation locations until late Wednesday
night. Overall, this first round of rain will most likely be quick
hitting with 12 hour rain amounts of 1.5 to 3.0 inches. Low
elevations have less than a 30% chance of even 1.0 inch of rain.

There is some uncertainty as to maximum rain rates. While most of
the rain will most likely be light and stratiform, the rapid wind
shift to the northwest along the front may allow for a quick burst
of high rain rates as showers are pushed against the coastal
mountains. HREF is showing a 10 to 20% chance of rain rates briefly
above 0.4 inches early Thursday evening.

Despite strong warm air advection ahead of the front, cool and very
dry air is likely to be trapped in Trinity County as the system
moves in. Strong evaporative cooling is likely to allow snow levels
to drop as low as 3000 feet. Some convective models are even showing
levels as low as 2500 feet. That said, overall snow fall will be
light with 3 to 5 inches of snow most likely around Scott Mountain
Pass with 1 to 2 inches at Trinity Center. That said, there remains
high certainty with potential for a few inches of heavier snow.

This first system will be followed by an even stronger system this
weekend. Ensemble plumes are showing much high confidence in a more
sustained period of moisture transport alongside a deep trough. This
setup will help create a moderate to strong atmospheric river. This
system will be much windier. NBM is showing an 80 percent chance of
southerly gusts in excess of 50 mph on ridges with even a 40 percent
chance at low elevations in Humboldt and Del Norte. Over 48 hours,
this second event will most likely produce steady rain totaling 4
to 6 inches at high elevations and 1 to 3 inches at  lower
elevations. Snow will continue for the interior, mostly only in the
high mountains above 4000 feet. Overall rain rates do not look
strong, but sustained rain will be enough to generate increased risk
of landslides and minor small stream and urban flooding. Extended
models suggest a high chance (80%) that a series of storm systems
will continue to impact the area over the next couple of weeks. /JHW

&&

.AVIATION...VFR skies under a mostly thin canopy of high clouds,
pockets of coastal haze, and light winds prevailed today. Conditions
will begin to change Wednesday as a low pressure system and
associated cold front began to impact the coast...mainly in the
afternoon. Above grounds winds will increase in the morning and
promote the possibility of LLWS at the Coastal Taf Sites. However,
conditions expected to remain VFR with rain starting in the
afternoon. /TA

&&

.MARINE...Today and Wednesday winds turn southerly and accelerate as
a frontal system approaches, bringing winds of 15 to 20 kts with
localized gusts of 30 kts downwind of Cape Mendocino. Gusts may
reach Gale Force in the northern outers as the boundary itself
approaches Wednesday evening, primarily directly downwind of the
Cape. The northern inners remain fairly sheltered from these winds,
where gusts peak around 10 to 15 kts Wednesday afternoon. A westerly
swell will fill in early Wednesday morning and will combine with
steep wind waves, bringing significant wave heights above 10 ft. A
compact jet of NW winds tracking SW of the approaching low center
may move over the waters Thursday morning, possibly bringing an
abrupt wind shift and Gale Force westerlies behind the frontal
boundary. However a significant amount of model spread still exists
in the exact placement of this low, with these stronger winds
possibly moving onshore near the Cape, or diving southward further
offshore. Have hoisted a Gale Watch for relevant timing should these
move through our waters, and this potential will continue to be
watched. A stronger system is forecast to arrive Friday into
Saturday, which has the potential to bring sustained Gale Force
southerly winds and large, confused seas this weekend.

&&

.BEACH HAZARDS...A long period westerly swell has filled in today,
peaking around 6-7 ft at 16 seconds. This wave groups in conjunction
with the rising tide in the afternoon presents a moderate risk of
sneaker waves through early Wednesday. Be cautious visiting beaches
and jetties today, as relatively large and unexpected waves could
sweep in without warning. Stay much farther back from the water and
never turn your back on the ocean. JB

&&

.COASTAL FLOODING...High astronomical tides are predicted from
mid-week through early next week for Northwest California. Southerly
winds may increase water levels above already high tides. Depending
on the strength and duration of these winds, this may cause some
minor to moderate coastal flooding in low areas around Humboldt Bay.
Elevated surf may exacerbate the coastal flooding on the open coast
over the weekend and waves could potentially wash over some of the
low lying areas of Hwy 1 in Mendocino county and Hwy 101 near
Crescent City. Coastal flood advisories or warning will be issued if
flooding is expected. Stay tuned! MKK/ZVS
