AREA FORECAST DISCUSSION
National Weather Service Eureka CA
509 AM PDT TUE OCT 11 2016

.SYNOPSIS...Generally dry weather will continue through Wednesday.
A series of strong pacific fronts will bring periods of gusty winds
and heavy rain to the region from Thursday through Sunday with a
brief break in the weather on Friday.

&&

.DISCUSSION...Low cloudiness blankets most of the coastal waters
this morning and extends well inland up adjacent river valleys.
ACV profiler data reveals that the marine layer has deepened to
over 3000 feet. As a result, ceiling heights are generally
several hundred feet higher than the past few days, and, as a
result, visibilities are higher and more variable. An upper
trough and an associated surface front produced a bit of light
rain across the extreme N portion of the area a few hours ago.
Support for additional rain is waning the in near term, and the
front will lift back to the N later today ahead of an approaching
storm system.

The first in a pair of strong, early season storm systems will
approach the area from the NW late Wednesday and early Thursday.
Multiple surface lows are forecast to rapidly deepen well N of the
area. Deep moisture will enter the base of the upper trough and spread
S along the Pacific NW coast, leading to a period of moderate to
heavy rainfall from Thursday afternoon through Friday morning.
Favored areas for the heaviest rainfall will be across S facing
terrain, particularly across inland Del Norte and N Humboldt
counties and the King Range of SW Humboldt county. Rainfall during
this event may top 3 to 5 inches in orographically favored areas.
Increasing S winds will lead to a rain shadow effect along
portions of the Redwood Coast, particularly around Humboldt Bay.
However, even there, rainfall totals will likely exceed 1 to 2
inches. Winds will ramp up quickly during the day Thursday with
gusts to 60 mph possible over higher terrain near and N of Cape
Mendocino. Wind advisories may be needed for portions of the
area. There is the possibility of isolated thunderstorms over our
N coastal waters Thursday night, possibly impacting adjacent land
areas of Del Norte county as well. Due to high uncertainty and
expected low coverage, have left out of the forecast for now, but
these may need to be added with later packages.

After a brief respite on Friday, another storm system will bomb
offshore the Pacific NW coast Friday night and Saturday. The GFS
drops the central pressure of the surface low to 955 mb Saturday
afternoon just W of Vancouver, Canada. Another slug of heavy
rainfall will accompany the attendant surface front. Additionally,
a very strong low-level jet will bring stronger winds to the area,
particularly at higher elevations and along coastal headlands.
Wind advisories and high wind watches/warnings for Saturday
afternoon and evening will likely be needed. Wind gusts in excess
of 70 to 80 mph are possible over the highest elevations near and
N of Cape Mendocino. Rainfall amounts with this 2nd system may be
similar to the 1st. Later shifts will need to monitor the area
river response to the 1st rains for possible impacts during the
2nd event. /SEC

&&

.AVIATION...Not a good night for aviation in the area. Crescent City
was in LIFR since 6Z, with ceiling around 200 to 400 feet and
visibility around 2 statue miles. Condition was slightly better
in Arcata, as it was bouncing between IFR and MVFR. For Ukiah,
some marine stratus sneaked into the area from the south, lowering
to ceiling to 500 feet and thus leading to IFR conditions.

Do expect LIFR condition in Crescent City should improve this
morning, and they may be getting to VFR/MVFR. However, do expect the
marine stratus to return this evening dropping conditions back down
to IFR/LIFR.

For Arcata, do expect IFR/MVFR conditions to improve by the morning,
getting to VFR for most of the day. However, do expect marine
stratus to return this evening dropping conditions back down to IFR
or lower.

For Ukiah, do expect VFR through today, some marine stratus may
sneak in from the south late tonight, dropping conditions to around
MVFR. /RCL

&&

.MARINE...Forecast is still on track, with little or no change to
previous forecast package. The biggest change is the issuance of
Storm Watch for the northern outside waters, and Gale Watch for the
northern inside water for Thursday morning through late Thursday
night.

For Tuesday, we will still be seeing N to NW winds off the NW
California coast. Wave height will be around 4 to 5 feet, mainly
from southwest swell. The low winds and seas are courtesy of a weak
high pressure off the NW California coast. This weather feature will
gradually be squeezed out by a strong weather front pushing east
towards the West Coast on Wednesday. Winds on Wednesday daytime will
be switching from north to south, then increase during the overnight
hours on Wednesday. Do expect storm force wind gusts to develop by
Thursday morning for the northern outside waters, while there will
be gale force wind gusts for the northern inside waters. Wave height
in excess of 20 feet in store for the northern outside waters on
Thursday. Do expect the winds to taper off for Friday.

Another strong weather front will push through the area on Saturday.
Do expect another round of strong winds and high seas on Saturday.
Looks like winds will drop off on Sunday. /RCL
