AREA FORECAST DISCUSSION
National Weather Service Eureka CA
510 AM PST Fri Feb 14 2025

.SYNOPSIS...Shower activity is expected to dissipate this afternoon.
Lingering cold air will promote colder temperature tonight, with
freezing temperatures across the interior valleys. Dry and calm
weather is forecast for Saturday, followed by more rain and mountain
Sunday through early next week.

&&

.DISCUSSION...Satellite imagery shows the Thursday's storm system
continuing to eject eastward away of Northwest California. Doppler
radar depicts isolated to scattered showers across the area early
this morning. Rain amounts over the last 24 hours (3AM Thursday to
3AM Friday) ranged from 1.5 to 3 inches, with localized higher
amounts up to 5 inch over the west-southwest facing windward
terrain in Southwest Humboldt and Mendocino County. The Russian
River at Hopland remain exceeding flood stage (15 feet) early this
morning. This main stem river will continue to receding and fall
below stage this morning. Shower activity is expected to gradually
taper off late this morning as a shortwave ridge will builds in
quickly downstream of the departing trough Friday afternoon. Dry
airmass will begin to filter across the area this afternoon
through late tonight. Lingering cold airmass, clear skies and
strong radiational cooling will promote colder temperatures
tonight, with freezing temperatures across the interior valleys.
For areas where skies clear out quickly, areas of valley fog are
expected to develop tonight into Saturday. Pretty quiet weather
conditions is expected for much of Saturday, before another
system approaches the area Saturday evening.

A broad upper level trough will move across the NEPAC on Saturday.
This feature will gradually weaken as it approaches the Pacific
Northwest, while a decay frontal system approaches Northwest
California. A low-level jet in advance will bring WAA in from the
west and aiding in snow levels rise about 4500 feet Saturday
evening and night. Modest pressure gradient tighten late Saturday
along the North Coast. Gusts from 25 to 35 mph will be likely over
the coastal headlands and exposed ridges. Light to locally
moderate rainfall rates is forecast to arrives Saturday night for
the northern portion of the forecast area, then continuing into
Sunday with rain chance increasing for areas east and south. These
front will be progressive and have less moisture flux compared to
Thursday storm. Total rainfall amounts from this system is
forecast to range from 0.5 to 1.5 inches along the North Coast
from Saturday evening through Monday afternoon. The highest
amounts are forecast to the farther northern portion of Humboldt
and Del Norte counties. Less amounts are forecast for Mendocino
and Lake counties with total rainfall from few hundredths to 0.30
inches.

Ensemble and deterministic models continue to suggest another
system approaching the area by mid next week, with little
potential (20% chance) of even moderate rainfall. Light rain is
most likely, again focused on the North Coast. /ZVS

&&

.AVIATION...Winds have turned northwesterly overnight as the low
center moves onshore into southern OR and weakens. Gusts 20 to 30
knots expected to continue at all terminals through early this
afternoon. Wind shear is likely in UKI until around sunrise before
winds diminish aloft. MFVR ceilings and reduced visibility's with
scattered rain showers will gradually diminish through this evening.
Light offshore winds will develop overnight in anticipation of
another frontal boundary approaching the area Saturday.

&&

.MARINE...NW winds are still gusting 20 to 30 knots this morning as a
large nearshore westerly swell fills into the waters. This swell is
still on track to peak at 15 to 16 feet at 15 seconds, enhancing
already elevated wave heights and generating high surf conditions.
Significant wave heights approaching 18 to 20 feet are possible this
morning before quickly diminishing along with winds by late this
evening. A brief period of sub-advisory conditions will be short
lived before another fast moving system brings another round of
gusty southerly winds Saturday into Sunday.

&&

.BEACH HAZARDS...A large westerly swell will peak this morning at 15
to 16 feet at 15 seconds, producing significant wave heights 18 to
20 feet. This swell will be enhanced by elevated NW winds developing
on the backside of a strong low pressure system. Max surf heights 20
to 22 feet are possible during through early afternoon, especially
on NW oriented beaches. Large breaking waves along the coast will
lead to increased wave run-up on beaches. Avoid large rocks,
jetties, steep beaches, and never turn your back on the ocean.

&&
