AREA FORECAST DISCUSSION
National Weather Service Eureka CA
357 AM PDT Wed May 2 2018

.SYNOPSIS...Temperatures over much of interior northwest
California will reside in the 70s to low 80s during the next 7
days, while temperatures in the upper 50s to low 60s are expected
along the coast due to the influence of a marine airmass.
Otherwise, dry weather is probable through the forecast period,
with the exception of possible shower development over the
interior during portions of Saturday and Sunday.

&&

.DISCUSSION...An amplified upper ridge was gradually shifting east
toward the west coast early Wednesday morning. Short term model
guidance brings this feature across the region Wednesday night
into Thursday. As that occurs, temperatures will warm aloft and an
inversion will form above the surface. The marine boundary layer
will deepen and moisten as that happens and aid in the development
of widespread stratus over the coastal waters that will spread
inland across portions of Del Norte, Humboldt, and Mendocino
Counties. Coastal temperatures during Thursday afternoon will
subsequently reside in the upper 50s to low 60s, while inland
valleys experience highs in the 70s.

Otherwise, dry weather is expected across the area through Friday.
Shower probabilities increase slightly over Trinity County
Saturday afternoon into Sunday as an upper wave approaches/passes
from the west. A more substantial upper trough may impact the
region Tuesday resulting in a better chance of more widely
spread, albeit light, rain chances.

&&

.AVIATION...MVFR stratus continues to plague ACV early this
morning, and this is expected to continue through mid to late
morning. Clouds are expected to dissipate late morning through the
remainder of the afternoon hours, resulting in VFR conditions at
ACV and at all other major terminals. A few low clouds may linger
into the afternoon across some interior hills and coastal valleys,
possibly affecting smaller airports like Kneeland and
Fortuna/Rohnerville at times. Winds are not expected to be nearly
as windy at coastal terminals as they have been the past couple of
days as well. MVFR to IFR stratus is likely to return to all
coastal terminals overnight tonight. /BRC

&&

.MARINE...While strong north winds are slowly weakening early
this morning, local buoys indicate that seas remain very large and
steep as of 3 AM...generally ranging between 10 and 15 feet at a
steep 9 seconds. As such, Hazardous Seas Warnings will remain
valid across all waters through at least 9 AM. Winds and seas are
expected to gradually improve through the day and into tomorrow,
and this trend will continue through the end of the week. North
winds ranging from just 5 to 15 kt will be the norm for the
remainder of the week, and with only a small lingering northwest
swell expected to move through the waters, seas are expected to
fall below 5 feet by tomorrow and remain there through at least
Sunday.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...Hazardous Seas Warning
     until 9 AM PDT this morning for PZZ450- 455-470-475.
