AREA FORECAST DISCUSSION
National Weather Service Eureka CA
1203 AM PDT Mon Jun 22 2026

.SYNOPSIS...High pressure builds in this week. Warmer and drier
conditions will persist through Thursday. Coastal drizzle and
breezier winds are possible Friday night into Saturday.


&&

.KEY MESSAGES...

- Warming trend for the interior will continue through this week.

- Troughing to the north of the area on Tuesday and Wednesday could
bring chances of interior thunderstorms.

- Cooler temperatures, breezy winds, and a slight chance of rain or
coastal drizzle are possible Friday into Saturday.

.DISCUSSION...High pressure continues over Northwest California
today. Temperatures continue to rise early this week with triple
digits possible for the warmest valleys by Monday. This warming
trend is likely to continue through at least mid week.

Troughing to the north of the area on Tuesday could bring additional
chances of interior thunderstorms. Confidence is not high as
instability and moisture currently look meager, but this will need
to be watched. Otherwise, dry and warm interior conditions are
likely for much of this coming week week.

Ensembles are showing fairly high confidence in a upper-level trough
moving north of the area late Friday into Saturday. NBM is showing
low, but nonzero chances for wetting rain (over 0.1 inches) in Del
Norte. The most likely scenario would be coastal drizzle. What is
slightly more certain is enhanced westerly wind Friday night into
Saturday. There are high chances of gusts over 30 mph in southern
Mendocino and Lake Counties, with breezy winds likely across the
area. Additionally, Cooler air and cloud cover with this trough will
drop interior high temperatures into the 80s. JB


&&

.AVIATION...With high pressure building back into Northwest
California, shallow coastal stratus is expected along the coast with
more clear conditions inland. IFR to LIFR ceiling conditions are
expected for coastal terminals with potential for fog as well.
Coastal stratus could linger into late morning. Stratus could travel
partially up coastal river valleys; however, VFR conditions are more
than likely anticipated for most interior terminals, such as KUKI.


&&

.MARINE...Northerly winds gradually increase today with isolated
gale force gusts likely in the lee of Cape Mendocino and Cape
Blanco. Seas that are currently dominated by a diminishing mid
period NW swell of around 5 to 7 ft will become more dominated by
steep wind waves. Steep wind waves may propagate into the inner
waters too, even as winds nearshore remain lighter. Winds diminish
Monday into Tuesday, especially nearshore, but stronger winds return
mid to late next week. JB
