AREA FORECAST DISCUSSION
National Weather Service Eureka CA
228 PM PDT Thu Mar 26 2026

.SYNOPSIS...Breezy to strong north and northeast winds are expected
through tonight. Dry weather and interior high temperatures well
above normal are expected Friday through Sunday. Significant cooling
and potential for widespread precipitation will arrive next week.

&&

.DISCUSSION...Gusty northerlies will continue through this evening
and then ease up overnight into Friday morning. E-NE winds develop
tonight and persist into Friday morning over the interior with
strongest gusts up to 30-40 mph over the higher elevations/ridges
and along the southern/eastern periphery of Lake County.

The airmass will remain dry tonight under offshore flow. Adiabatic
warming from the large scale subsidence will likely result in a
wide range of overnight low temperatures. With a warmer airmass
building tonight and winds generally diminishing, wind sheltered
valleys and coastal areas will stand the best chance for frost and
freezing/subfreezing temperature. Some wind sheltered valleys
will dip down into the lower to mid 30`s while breezier wind prone
areas exposed to adiabatic warming may not even dip below 60F
(mostly in the thermal belts and ridges). Frost advisories have
been issued for the interior valleys of Mendocino County as well
as coastal areas of Del Norte and Humboldt again. Interior portions
of Humboldt and Del Norte are 6 days from the start of the growing
season (Apr 1) while Trinity County is 21 days away (Apr 15). That
is why frost/freeze products have not been issued for these zones.

Otherwise, dry and stable weather is expected for the remainder
of this week and into the weekend. Generally above normal high
temperatures and areas of minor heat risk are forecast for mostly
the interior as a broad flat ridge aloft dominates. The warmest
locations will continue to be in Lake, Trinity and interior
Mendocino Counties where max temps are projected to peak into the
upper 70s to mid 80s Fri-Sun. This is 10-20F above late March
averages. Overnight low temps will remain seasonably chilly with
perhaps some valley sites cooling into the lower to mid 30`s,
especially in the valleys of Trinity. Overnight temperatures will
remain elevated (50s and 60s) within the thermal belts and over
the ridges exposed to breezy E-NE winds through the night. No
huge changes are anticipated this weekend except for an increase
in coastal stratus and perhaps a ramp up in onshore or NW winds.

National blend of models continue to trend much cooler and wetter
next week, Monday March 30 to Thu, April 2nd. Our long stretch of
above normal warmth in the interior will finally come to an end
next week with highs trending near or just under early April
normals (upper 50s to mid 60s) by mid week (Wed). Moreover,
precipitation chances will be on the rise throughout the forecast
area next week. How much precipitation and the exact timing
remains uncertain. Highest WPC/NBM 6-hourly rates appear to
arrive on Wed, but this could easily speed up or slow down by
12-24 hours. NBM 3-day totals 5 AM Mon-5AM Thu range from over 2
to 5 inches on the higher end (90th percentile) to not much more
than half an inch on the lower end (10th percentile). Most of the
precip is concentrated in the usual wet spots of Del Norte, SW
Humboldt and NW Mendocino, while southern Lake and southern
Mendocino may end up with much less. There is a 60-80% chance for
over 6-8 inches snowfall for the high mountains over 3-days too.
National blend still has 6-hr and 12-hr thunderstorm chances less
than 15%. If the cold core aloft dips far enough south we could
definitely see some low top thunderstorms and small hail. March is
usually the max on average for small hail. The wet season is not
over just yet and the weather could get quite active by mid next
week. Stay tuned for updates and more details.

.AVIATION...Besides some high clouds streaming over the region,
skies have remained clear today. A few valleys will likely see
fog develop tonight with lighter winds across the interior.
Additionally, some coastal clouds may develop south of Cape
Mendocino, but otherwise clear conditions and VFR are expected at
all the TAF sites through the forecast period. Northerly gusty
winds along the coast today will decrease through the evening,
becoming light easterly during the overnight hours. Winds will
again increase during the late morning and afternoon on Friday but
should be lighter than what has been occurring today. /RPA

&&

.MARINE...Northerly winds are peaking this afternoon with surface high
pressure situated a little west of the waters. A building thermal
trough will attempt to push toward the coast tonight allowing the
tightest pressure gradient to shift west and north of the waters.
Thus, the near gale to gale force northerly winds will decrease
Friday morning leaving steep seas, especially in the outer waters.
Small craft conditions will most definitely persist through Friday
night with the potential for hazardous seas warnings following the
gales in the outer water zones.

Winds will decrease over the weekend as an area of low pressure
begins to develop off the California coast. This will significantly
reduce the pressure gradient across the waters. A weak front is
forecast to move through the waters on Monday allowing the northerly
winds to increase slightly in its wake. The next chance for strong
winds will be mid next week as a more potent frontal system moves
into the region. /RPA
