AREA FORECAST DISCUSSION
National Weather Service Eureka CA
1228 PM PDT Tue Jun 23 2026

.SYNOPSIS...High pressure continues to build over the area, bringing
warm and dry conditions. Isolated thunderstorms are possible in
northern Trinity County Wednesday afternoon. Rain is possible for
the North Coast Friday.

&&

.KEY MESSAGES...

- Warming trend for the interior will continue through Thursday.

- Very slight chance for thunderstorms in northeast Trinity
  County Wednesday.

- Chance of rain for the North Coast Friday.

- Cooler temperatures & breezy winds likely late week into the
  weekend.

&&

.DISCUSSION...High pressure continues to build over Northwest
California. Warm interior conditions with high temperatures for most
valleys reaching the 90s. The warmest areas, along the Trinity and
Klamath River Valleys, could see triple digits. This warming trend
is likely to continue through Thursday. Coastal areas continue to
see stratus continuing into the afternoon with only brief and
partial clearing. Clearer skies are possible Wednesday with breezier
winds off the coast.

Troughing to the north of the area today and Wednesday could bring
additional chances of showers and thunderstorms to northeast Trinity
County. This afternoon, confidence is very low as both moisture and
instability remain meager, but an isolated rain shower may be
possible. Confidence is very slightly higher Wednesday with a modest
increase in moisture, but still chances remain at around 10%.

There is high confidence in a upper-level trough moving through the
area Friday. Measurable rain is very likely in northern Humboldt and
Del Norte, while chances of wetting rain (over 0.1") are around 60%
in coastal Del Norte and 30% over coastal Humboldt. Outside a few
sprinkles, the rest of the area is likely to remain dry. Despite the
lack of rain in the interior, increased cloud cover and breezy winds
will drop high temperatures 15 to 20 degrees in the interior with
most areas in the 70s by Saturday. Saturday night, chilly
temperatures are possible, especially for June. Frost may be
possible in Hayfork and surrounding valleys with NBM showing around
a 30% chance for low temperatures of 36 or lower.

Gusty westerly wind in Lake and southern Mendocino Friday is highly
likely behind the frontal passage. NBM shows over 70% chance for
gusts over 30 mph for much of Lake County, while the higher terrain
and wind prone areas can see gusts over 40 mph. Similarly breezy
winds are possible Saturday afternoon and evening, with around 50%
chances for the lower elevations to see gusts over 30 mph. Sunday,
widespread gusts ease, but the east side of Lake County could see
gusty northeasterly winds. These conditions will need to be watched
for a potential fire weather threat. Coastal areas are also likely
to be breezy with gusts of 20 to 30 mph possible in the afternoons
this weekend into early next week. JB

&&

.AVIATION...(18Z TAFs)...LIFR to IFR ceilings are likely to persist
along the coast today. Some brief scattering and lifting is possible
this afternoon, but stratus will likely be back by sunset. Building
high pressure is likely to bring a shallower marine layer, bringing
a higher potential for fog overnight. LIFR ceilings and visibilities
are both possible along the coast. Most interior areas will likely
see VFR conditions through the night outside of the near-coast river
valleys. JB

&&

.MARINE...Northerly winds remain light to moderate today with the
strongest winds in the lee of Cape Mendocino. Steep seas have been
slow to subside in the outer waters, but wave heights are likely to
drop below 8 ft this afternoon and evening. Much milder seas are
found nearshore. Winds increase tonight into Wednesday with near-
gale force gusts possible in the lee of Cape Blanco and Cape
Mendocino. Winds nearshore will be much lighter, but steep seas of 5
to 8 feet are likely to propagate into the inner waters. Seas
generally remain dominated by wind waves this week, with only minor
mid to long period southerly and northwesterly swells. Winds ease
again Thursday night into Friday as a cold front approaches the
area. Seas will likely remain elevated as a steep northwesterly
swell of around 6 to 8 ft at 9 seconds arrives Friday night into
Saturday. Strong northerly winds are likely to return late Saturday
into Sunday. JB

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...
None.
NORTHWEST CALIFORNIA COASTAL WATERS...
     Small Craft Advisory until 3 PM PDT this afternoon for
     PZZ470-475.
