AREA FORECAST DISCUSSION
National Weather Service Eureka CA
1200 AM PDT Tue May 19 2026

.SYNOPSIS...Northerly winds have diminished considerably, but 
will be breezy each afternoon. Clear and dry conditions will remain 
through the week with a warming trend through Thursday. Temperatures 
will trend lower this weekend weekend. 

&&


.KEY MESSAGES...

-Northerly winds are much lighter, but will be breezy in the 
afternoons. 

-Generally clear skies and dry conditions, even along shore, through 
the week. 

-Conditions will warm through Thursday with highs in the interior 
peaking near 90.

.DISCUSSION...Consistently strong northerly winds have diminished 
early this week for Northwest California as the pressure gradient 
eases. Winds will die down over night and then become generally 
breezy in the afternoons throughout this week. Overnight lows will 
be on the chilly side again tonight, but will begin moderating this 
week with building high pressure. Some areas of localized frost will 
be possible in the Hayfork and Larabee Valley this morning.

Conditions will remain very dry with warming temperatures through 
the week. Highs will most likely top out around 90 for the interior 
on Thursday. This will constitute only a minor HeatRisk for this 
time of year. Hotter temperatures will help reform a marine 
inversion and will increase chances for coastal stratus and fog this 
week


&&

.AVIATION...Northerly winds have, for the most part, moved
offshore, except at Point Saint George and Cape Mendocino where
winds will remain elevated overnight. Gusts up to 20 knots can be
expected around KCEC very early this morning before dying down
before sunrise. Other terminals in Northwest California will
experience generally calm winds before sunrise. This pattern of
diminished winds overnight and higher winds during the afternoon 
will continue through the work week. Widespread VFR conditions are
anticipated with a slight probability of coastal stratus forming 
around Humboldt Bay early this morning. Throughout this week, 
coastal stratus is likely to form each night and burn off after 
sunrise as high pressure continues for the region. /JLW


&&

.MARINE...The pressure gradient relaxes slightly and the strongest
winds move farther off the coast as the high pressure builds in. 
However, a large area of gale force gusts around 34-45 kts are 
expected across all zones, with the strongest winds downwind of 
Cape Mendocino. Steep to very steep, hazardous seas will continue 
with the elevated winds. Conditions will remain hazardous across 
the waters for much of the work week with strong to gale force 
northerly gusts and steep to very steep seas. Gale force winds and
very steep seas are forecast to persists across the outer waters 
through Friday. /ZVS
