AREA FORECAST DISCUSSION
National Weather Service Eureka CA
1213 AM PDT Tue Jun 30 2026

.SYNOPSIS...Gusty north winds continue along shore through
Wednesday. Seasonably warm to below average temperatures through
Thursday before temperatures warm up Friday and through the holiday
Weekend.

&&

.KEY MESSAGES...

-Gusty north winds each afternoon along shore through late week.

-Below normal high temperatures through Thursday

-Temperatures turn hotter over the holiday weekend


.DISCUSSION...With a strong Pacific ridge of high pressure in
place, the northerly winds gusted in excess of 30 mph along the
coast Monday, with higher strength gusts along Cape Mendocino and
Point St George. Very similar conditions as described will continue
through mid week. Some weak disturbances will progress through from
the north late Tuesday through Wednesday. Summertime systems such as
these always bear watching for convective activity, but the lack of
available moisture should limit development to some enhanced
afternoon cumulus over the Yolla Bolly or far northeast Trinity
County.

The strong Pacific high begins breaking down Thursday. A weak trough
may move through late Thursday through Friday, with little impact
expected other than some potential light drizzle. This feature has
been progressively modeled father north however. Interior
temperatures look to quickly rebound through next weekend behind the
trough as a desert southwest high strengthens in advance of a
stronger Pacific trough. There are high probabilities for high
temperatures over 90 Saturday and Sunday for the interior valleys.
Probabilities quickly lower for highs over 95 outside of a couple of
the hottest valleys where upper 90s to up to 100 is possible. This
would result in some minor to locally moderate HeatRisk.


&&

.AVIATION...Northerly winds eased overnight Monday. The well-mixed
and dry environment will extend the period of VFR conditions, with
the exception of around Humboldt Bay. Some stratus may develop
around Humboldt Bay again, with mainly MVFR ceiling levels. Coverage
and duration of ceilings will be very limited from expected light
easterly winds. Winds will continue to be the main concern as they
quickly increase Monday, with gust 20 to 30 kts expected again at
the coastal terminals. Higher gusts will occur near Point St George
and CEC.


&&

.MARINE...Strong northerly winds are over the waters with steep,
large to hazardous seas are underway over all zones. Gale Warnings
remain over the outer waters, but gale conditions can be expected
around Point St George and Cape Mendocino. The proximity of gale
conditions to the inner zones will continue to allow poorly modeled
large to hazardous seas to pulsing into the inner waters at times.
Up to 12 ft seas are being observed into the near-shore inner
waters. The greatest threat for this will be over the late Monday,
Tuesday, and Wednesday after maximum afternoon winds are achieved.
Hazardous Seas Warnings remain for the inner zones to cover this
threat. The Gale and Hazardous Seas warnings are extended into
Thursday morning when conditions begin to slowly improve.
