AREA FORECAST DISCUSSION
National Weather Service Eureka CA
503 AM PDT Tue Mar 25 2025

.SYNOPSIS...A warm, dry pattern continues as high pressure builds in
to the region. A sneaker wave threat will be prevalent today into
Wednesday with a long period swell. Precipitation and breezy to
strong winds are likely Wednesday through the end of the week as
a more active pattern sets in.

&&

.DISCUSSION...Some patchy to dense areas of fog are back this
morning, mainly for coastal Humboldt and Del Norte. This thin and
shallow fog layer should pull pack over the ocean later this
morning. The strong ridge of high pressure will be of highest
amplitude today, and this will aid in the warmest temperatures of
the week. Please see the Beach Hazard statement regarding the
sneaker wave risk today if beach plans are being made. Today will
also mark the final day of warm and pleasant weather before an
abrupt shift back to cooler temperatures and active pattern.

To begin, a NE Pacific trough and quickly strengthening surface low
will drive in a front Wednesday. Anomalous CAPE has continued to be
flagged with this first system on Wednesday. Thunderstorms are
forecast for the far interior mountains of Trinity County and
possible into interior Del Norte on Wednesday. The Storm Prediction
Center is forecasting a Marginal Risk for severe thunderstorms for
interior southern Oregon, so the ingredients are there for some
stronger end storms to form over our area.

Southerly winds will strengthen Wednesday as a southerly 925mb jet
up to around 45kts forms. Given the forecast instability with this
front, there is a greater chance for some of these stronger winds
mixing closer to the surface. A Wind Advisory is out starting
Wednesday morning. NBM confidence for wind gusts of 45 mph are
moderate to high for the interior ridges of Del Norte and Humboldt
counties (66 to 81%) for Wednesday. Wind gusts up to or over 35
mph can be expected closer to the coast around Humboldt Bay (48%
chance of exceeding 35 mph). Wind gusts over 45 mph are forecast
and probable for coastal Del Norte (61%). Rainfall amounts will be
on the lighter side with this first front, around 0.5 to 1.5
inch. Snow levels will not be low, at around 4000 ft and a couple
inches of snow are forecast for Scott Mountain pass in NE Trinity
County.

Winds will remain breezy Wednesday night as the 977mb low pivots
eastward off the OR and WA coast. Winds from a stronger coastal
southerly jet will further increase Thursday as a result. Rainfall
will be moderate to locally heavy along the North Coast and in Del
Norte Thursday. There has been, and remains uncertainty on the wind
strength for Thursday as global models are struggling with how fast
the cyclone weakens. The deterministic ECMWF is more of an outlier
with its forecast of a weakened low and much weaker 925 mb winds.
Confidence is relatively good on a 925mb jet up around 65 kts on
Thursday, with breezy to strong winds to the lower elevations of Del
Norte and Humboldt. The highest probabilities from NBM are in Del
Norte, with modest chances for gusts of 50 mph for the interior
ridges. Looking at the grand ensemble spread, and ECMWF ensembles,
wind gusts of 45 mph around Humboldt Bay and over 55 mph gusts for
coastal Del Norte are possible (25% chance). Interestingly, NBM 90th
percentile wind gusts are highest for Wednesday afternoon, given the
anomalous CAPE, it cannot be ruled out, and also highlights to
continued uncertainty with the wind forecast.

There will be lingering precipitation and gusty southerly winds on
Friday. Snow levels look to hold at 3500 to 4000 ft, but impacts
to the passes look minimal at this time. Scott mountain pass may
receive and additional few inches of snow. There looks to be a
pause in precipitation Saturday, followed by a potential strong
and compact system Sunday. There are big questions as to where
this low ends up (possibly farther south). As expected, there is
a large spread in ensemble forecast winds, but there is a low
chance for high impact winds Sunday. Day 8-14 Climate Prediction
Center precipitation stands at above normal for the Western
United States, and there are indications (supported by the
clusters) for some late season atmospheric river activity for
early April. /JJW

.AVIATION...Very shallow stratus and fog has slowly formed along
shore overnight, bringing patchy and inconsistent IFR and LIFR
conditions to coastal terminals. High resolution ensemble guidance
suggests fog will continue to thicken through around 10 AM before
burning off and clearing to VFR by about 3 PM. As always, however,
there is high uncertainty with how the stratus will behave. Given
the thin and isolated nature of the current stratus layer, should
the forecast deviate, it is most likely to deviate by clearing out
sooner. The exception would be Crescent City where the HREF places a
40% chance of it never clearing out at all! There is one more night
of possible LIFR and IFR fog tonight, though an approach storm
system will make the fog forecast tonight very uncertain. /JHW

&&

.MARINE...Wind have generally calmed overnight and will remain
gentle through the day today, with gusts generally below 15 kts
through early Wednesday. Though calm, winds will gradually turn
southerly as an intensifying Pacific cyclone approaches shore. A
moderate, lone long period westerly swell around 7 feet will control
the sea state today with little wind waves to speak of.

Much more unsettled conditions will quickly build during the day
Wednesday. A strong Pacific cyclone is forecast to skirt from south
to north across the waters. This will bring strong gale conditions,
especially to the northern waters with southerly gusts in excess of
40 kts. Guts sin the southern waters will be weaker with only
isolated gale conditions. There remains larger uncertainty about
exactly how close to shore the cyclone will get. While gale
conditions are still most likely (70% chance) fir the inner northern
waters, there is more uncertainty regarding the strength and
duration near shore.

Regardless, gale winds will steepen short period seas to over 10
feet in all waters by early Thursday, with seas over 17 feet in the
northern waters. Gale conditions will most likely begin to ease by
late Thursday afternoon, but a very steep mid period westerly swell
in excess of 20 feet will build behind the cyclone, maintaining
steep and hazardous seas through the end of the week. /JHW

&&

.BEACH HAZARDS...A a lone long period westerly swell up to 7 feet
will dominate the sea state through the day today. With little short
period seas to speak of, this swell will create a moderate  sneaker
wave risk today into early Wednesday. These long period waves can
generate sporadic, deceptively calm lulls in wave activity ending
with a large set of breaking waves unexpectedly washing far up
beaches.

Stormy weather will build in Wednesday and Thursday. On the tail end
of the storm, a large westerly swell is currently forecast to build
in in excess of 22 feet ft which will generate dangerously large
surf of  24 to 28 ft on area beaches through the end of the week.
