AREA FORECAST DISCUSSION
National Weather Service Eureka CA
251 PM PST Mon Feb 2 2026

.SYNOPSIS...Dry weather is expected through the work week. Warm days
and chilly mornings likely for much of the area. Rain possibly
returns this weekend.


&&

.DISCUSSION...High pressure has started to rebuild over the area,
bringing mostly clear skies and dry weather. Some areas of valley
fog have been observed in some of the river valleys with chilly
overnight conditions also being observed with low temperatures in
the 20s and 30s. This pattern is likely to continue for much of this
week as high pressure remains overhead. High temperatures will
likely trend upwards over the week, with mid 70s possible in some of
the warmest valleys mid this week. The low sun angle and colder
nights will prevent some of the valleys, like most in Trinity
County, from seeing as warm of temperatures, with low to mid 60s
forecast. Coastal stratus will keep temperatures moderated today and
perhaps tomorrow, though once stratus scatters out in the afternoon,
temperatures of high 50s to low 60s are likely. Offshore flow and a
shallow marine layer will likely reduce coastal stratus by mid to
late week, which could bring temperatures into the mid 60s, but also
chilly temperatures in the mid to high 30s overnight.

Long term ensembles are suggesting the ridge finally starting to
break down by the weekend. Uncertainty is high with how this will
develop. NBM is showing around 50% probabilities for over an inch of
rain this weekend into early next week with higher probabilities in
the higher terrain. However, NBM does show about a 20% chance for
Mendocino and Lake Counties to remain dry. More detail will become
clearer in the coming days. Stay tuned! JB

.AVIATION...VFR conditions prevail over most terminals in
Northwest California through this afternoon. Another round of low
clouds for coastal terminals may be possible tonight, but light
offshore flow could reduce the coastal coverage. However, interior
valleys will most likely see low clouds and fog overnight. KUKI
could even see visibility reductions very early Tuesday morning.


&&

.MARINE...A westerly swell will continue to move through the waters
this morning with seas above 10 feet for most locations through
late this afternoon. High pressure will build over the west coast
this week with light winds expected over the coastal waters. Seas
will subside on Tuesday into Wednesday with conditions likely to
remain below small craft. Another large westerly swell will build
into the waters Thursday into Friday with heights expected to be
around 11-13 feet at 15 seconds. With winds remaining light to
moderate, short period seas will remain small and westerly swells
should be the dominating wave through the forecast period. /RPA


&&

.BEACH HAZARDS...A long period westerly swell train continues
today with heights between 10 and 13 feet with periods near 15
seconds. This swell may be too large for sneaker waves, though it
could still pose a threat to beachgoers. Breakers up to 16 feet for
west and northwest facing beaches are forecast based on average
beach slope profiles today. Beachgoers venturing near or in the
surf zone should remain vigilant. Avoid rocks, jetties and steep
beaches. Another large swell may bring slight sneaker wave threat
Thursday into Friday. /RPA
