AREA FORECAST DISCUSSION
National Weather Service Eureka CA
1251 AM PST Sat Mar 7 2026

.SYNOPSIS...A warm, dry, and summer like pattern will peak Saturday.
Very light coastal drizzle is possible Monday but otherwise
similar weather will continue next week and particularly gusty
north winds near shore around midweek.


&&

.DISCUSSION...High pressure will peak over the weekend withs
highs in the upper 70s across the interior. There remains a slight
(15%) chance of some isolated highs even over 80 on Saturday
afternoon. Some gusty north winds will remain in the afternoon,
but slight weakening may allow for coastal highs in the 60s.
Regardless clear and relatively dry conditions will persist.


A very subtle shortwave passing the early next week could bring very
light drizzle within the marine layer around Monday, most likely
just for Del Norte. Otherwise, the wave will help push strong north
wind s into the coast, where north gusts could again exceed 30 mph
in the afternoon. Overall conditions will remain dry with interior
highs right around 70. Most models have now trended towards high
pressure lasting all next week with with little more than drizzle
(20% chance) possible later in the week along the far north coast.
High pressure will continue to promote warm interior temperatures,
though weakening wind through the week will most likely encourage a
stronger but shallower marine layer near shore. /JHW

.AVIATION...(07/06z TAFS)...MVFR and IFR ceilings will be
possible (30% chance) over Humboldt Bay/Eel delta and KACV tonight
through Saturday morning. Satellite imagery showed low cloud
amassing over the Eel delta and southern Humboldt Bay Friday
evening. Mesoscale models have these clouds dissipating or pushing
offshore overnight as a thermal trough builds and northeast-
easterly flow strengthens. Some low clouds may meander in and out
of KACV into early Sat. Otherwise, VFR conditions are expected to
prevail through Saturday. Gusty northerly winds are expected again
on Sat, primarily for KCEC. Mesoscale models are starting to
converge on low ceilings and vsby obscuration for coastal
aerodromes Sat night. Detail are scant at the moment.


&&

.MARINE...Marine conditions will remain hazardous for small craft
through this weekend as steep northerly waves combine with short
period NW swell. Gale force northerlies have abated except for the
southern outer waters and near Cape Mendocino where gale gusts to 35
kt are forecast to continue into early next week. Strong to moderate
breezes with large steep northerly waves are forecast to continue
for much of the waters through the weekend as a thermal trough
meanders near the coast. Widespread northerly gales and near storm
gusts are expected early next week after the passage of a front.
