AREA FORECAST DISCUSSION
National Weather Service Eureka CA
1230 AM PDT Sun Aug 16 2026

.KEY MESSAGES...

* Smoke remains over areas outside of the marine layer due to local
  and distant wildfires.

* Temperatures close to normal remains through the first half of
  the coming week.

&&

.SYNOPSIS...An upper level troughing pattern has stalled over the
eastern Pacific. Inland areas can expect cooler temperatures with
the coast continuing to have overcast conditions and brief afternoon
clearing. Generally mild weather is expected for the next week.

&&

.DISCUSSION...An upper level trough has set up over the eastern
pacific while an upper level ridge dominates over the central US.
This pattern is forecasted to continue through the weekend and
into early next week. The decreased surface pressure has supported
a deeper marine layer with stratus reaching up the coastal river
valleys with areas further inland experiencing seasonable
temperatures in the upper 80s to lower 90s.

Higher surface pressure may briefly rebuild early to mid week, but
models are not showing a significant warm up and interior
temperatures are likely to remain near normal (with most valleys in
the 90s). Coastal areas are likely to see stratus persist through
the afternoon, and this is likely to continue so long as afternoon
winds remain light. Any clearing that does happen will most likely
be short lived before filling in again after sundown.

For the Trinity River Valley and areas in valleys of Trinity County,
smoke will continue to form each day and settle in the valley floors
each evening. Thankfully, weak inversions are likely to persist
which should offer some slight relief from any dense smoke earlier
in the day.

&&

.AVIATION...With a deep marine layer has caused MVFR to IFR ceilings
through the evening. Winds along the coast are light, yet should
lean southerly through the overnight hours. Clearing in the morning
is not expected, and if it occurs will be short lived. Inland areas
will experience VFR conditions with winds switching between nighttime
calm and daytime upvalley flow. Coastal river valleys are likely to
see stratus (KUKI included) late overnight before clearing late in
the morning.

&&

.MARINE...Northerly winds remain in the outer waters with southerly
winds in the inner waters where foggy conditions are likely. Short
period waves will continue to decrease through Sunday before slowly
growing again entering next week. A long-period southerly swell of
~3ft has built into the region as well. The overall sea state should
remain mixed with these two wave groups through the start of next
week. Light to moderately breezy (~20kt) winds are expected through
the extended forecast of this coming work week.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...
None.
NORTHWEST CALIFORNIA COASTAL WATERS...
None.
