AREA FORECAST DISCUSSION
National Weather Service Eureka CA
304 PM PDT Mon Jun 29 2026

.KEY MESSAGES...
* Gusty north winds each afternoon along shore through midweek.
* Gradual warming and drying trend inland.
* Temperatures turn hotter over the holiday weekend, resulting in
  minor HeatRisk.

&&

.SYNOPSIS... Seasonably warm and dry conditions will build through
midweek with gusty north wind along shore each afternoon.

&&

.DISCUSSION...Temperatures warmed today behind a dry, southward
passing shortwave disturbance. If there was available moisture
with this passing perturbation, nocturnal thunderstorms would be
possible. However, the environment is dry and stable, keeping
skies mostly clear across most areas today. Interior valleys warm
to the mid-80s to around 90 degrees Monday afternoon. Very similar
conditions will continue through midweek.

The strong Pacific high responsible for this pattern begins breaking
down Thursday. A weak trough may move through late Thursday through
Friday, with little impact expected other than some potential light
drizzle and slightly more mild conditions. Interior temperatures
look to quickly rebound through next weekend behind the trough as a
desert southwest high strengthens. There are high probabilities for
high temperatures over 90 degrees Saturday and Sunday for the
interior valleys. Probabilities quickly lower for highs over 95
degrees outside of a couple of the hottest valleys, which will keep
the HeatRisk categorized as minor over the holiday weekend.

&&

.AVIATION... Northerly winds eased overnight Sunday. The well-mixed,
dry, and stable environment will extend the period of VFR conditions
for most areas, with the exception of around Humboldt Bay. Some
stratus formed around Humboldt Bay again, with MVFR to IFR 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 gusts 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 while steep
seas build in response. 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
favor hazardous seas to pulse into the inner waters at times, as
is being observed. The greatest threat for this will be over late
Monday, Tuesday, and Wednesday after maximum afternoon winds are
achieved. A Hazardous Seas Warning has been issued to cover this
threat given what was observed Sunday night.
