Area Forecast Discussion
National Weather Service Eureka CA
455 AM PDT THU MAY 26 2016

.SYNOPSIS...A few showers are possible over the Yolla Bollys this
afternoon, otherwise dry weather will stretch through early next
week. Coastal areas will see a mix of clouds and sun through the
period.

&&

.SHORT TERM (Today through Sunday)...Low clouds have expanded
across the Redwood Coast this morning as well as in many inland
valley locations. Expect clouds to thin over land with daytime
heating. Clouds will linger once again over coastal Humboldt
County N of Cape Mendocino as N winds piles up low-level moisture
against the terrain. Indications are that inland cloudiness will
thin faster than on Wednesday and that there may be more eventual
breaks in the clouds closer to the coast. Convective cumulus will
develop once again over the interior mountains, but this will be
less expansive than on Wednesday as well. A bit of drizzle is
possible along the Redwood Coast early this morning, and isolated,
generally light showers are possible late in the afternoon over
the Yolla Bollys. However, the bulk of the area will remain dry
today.

Dry weather is expected into the weekend with skies becoming
partly cloudy to mostly sunny across most of the area. Patchy
coastal lowland and valley fog will be possible each night and
early morning.

Near normal temperatures today will warm to above normal levels
over the interior by Friday through Sunday. Near normal temperatures
are expected to continue near the coast. /SEC

.LONG TERM (Sunday night through Thursday)...Mostly dry weather is
expected to persist into the middle of next week as an upper high
pressure ridge over the E Pacific gradually shifts E. Generally
weak disturbances will impact the Pacific NW and remain N of our
county warning area. Seasonable weather is expected along the
coast with warm weather inland. Early indications are that an
upper trough will dig over the E Pacific by Wednesday, bringing
more seasonable temperatures later in the upcoming week. /SEC

&&

.AVIATION...Stratus brought MVFR conditions to interior valleys and
coastal areas once again this morning. Expect the valleys to scatter
out similar to yesterday with clouds eroding away by the late
morning hours. Areas along the coast will be a little different.
Models suggests that clouds will linger around Humboldt Bay and
southern Mendocino but coastal eddies could cause ceilings to bounce
between overcast and scattered periodically through the day. Expect
KCEC to scatter out earlier in the day but KACV will more or less be
variable with broken blue skies possible through the afternoon. The
best chance for scattered skies for KACV will be late in the
afternoon/early evening. MVFR ceilings should return to Humboldt Bay
and parts of the Mendocino coast tonight. Offshore flow late tonight
will help restrict the stratus from spreading and potentially help
improve conditions at KCEC overnight. KUKI should remain VFR through
the TAF period. /KML

&&

.MARINE...North winds will continue to increase today as building
high pressure offshore pinches the pressure gradient across the
coastal waters. Wind gusts will reach 35 to 40 kt by later this
afternoon across the outer waters and near coastal points and great
capes. Strong north winds will continue through Friday. The gale
watch has been upgraded to a warning to account for these stronger
wind gusts offshore. Steep waves will build in response to the winds
with seas approaching 10 to 13 ft offshore. Steep waves will propagate
nearshore making for large steep conditions across the inner waters.
A hazardous seas warning may be needed for the inner waters this
evening but it looks to be on the marginal side as of now. Stay
tuned.

Winds will subtly diminish from north to south over the weekend as a
passing wave disrupts the pressure gradient. Fresh north winds will
persist early next week before the gradient relaxes more significantly
by the latter half of the week. Steep waves will diminish with the
winds and a myriad of smaller scale NW and S swells will propagate
the waters through next week. /KML
