AREA FORECAST DISCUSSION
National Weather Service Eureka CA
430 AM PST Tue Dec 18 2018

.SYNOPSIS...Another Pacific front will bring more rain and gusty
winds to the area this morning. A brief break in the weather will
occur on Wednesday followed by yet another weather system arriving
to the area on Thursday.

&&

.DISCUSSION...Light warm frontal precip is arriving to areas just
north of the Del Norte/Curry county boarder this morning. This
will continue until the cold front sags south and rainfall rates
increase beginning around sunrise.  Rainfall totals will be
highest across Del Norte County, where as much as 2.5 to 3 inches
will be possible over interior areas. Amounts will be lower
farther to the south, ranging generally from 0.5 to 1.00 inch over
most areas of Humboldt and then more on the order of 0.25 inches
towards Mendocino County. Rain will quickly taper off to showers
overnight and then come to an end by Wednesday morning. The other
primary impact from this system will be another round of gusty
winds from now through early this afternoon. Latest guidance
continues to indicate 925mb winds hitting 50kt over coastal Del
Norte county this morning and that has verified at buoy 27
already. The main cold frontal boundary will start to reach the
coast right around sunrise and last through at least noon on
Tuesday. A break in the active weather pattern is in store for
Wednesday as a shortwave ridge briefly amplifies over the west
coast. This will yield at least partial clearing and some sunshine,
particularly over interior areas where colder temperatures and
maybe even some patchy frost in the colder valleys of Trinity
County will be possible by Thursday morning. The break will be
short lived however, as the ridge is quickly displaced eastward by
an approaching trough and another cold front on Thursday. There
is still some uncertainty regarding the timing of this system, but
another round of wind and rain appears to be in store some time
on Thursday, whether in the afternoon or later in the evening. The
progressive pattern then continues for the remainder of the week,
with another relative lull in onshore zonal flow Friday and
Saturday in advance of the next system on Sunday.

&&

.AVIATION...Another feed of moisture from an approaching front
will likely bring deteriorating conditions to all terminals
through the day. The other issue will be another round of gusty
southerlies. The potential for low level wind shear will once
again be on the rise as S winds aloft increase. Although the winds
just above 3000 ft agl do not look as strong as the last previous
fronts. Moderate to heavy rain will accompany frontal passage
later this morning thus mvfr to brief ifr conditions are possible
at the coastal terminals late this morning.

&&

.MARINE...South winds will continue to increase this morning as
another frontal system impacts the waters with strong southerly
winds and large steep wind waves. The models indicate the surface
boundary weakening with time as it heads southward but gusts
across the northern waters but buoy reports are already well
into the mid 30s while buoy 27 has gusted to 49. A huge ground
swell will continue to subside today but the hazardous seas will
persist through the afternoon as short period wind waves combine
with the tail end of the decaying westerly swell. Another
reinforcing west swell will generate spike on Wednesday. Expect
seas will to remain hazardous through much of the week as this
next swell slowly decays. The models were in better agreement with
another frontal passage across the waters on Thursday. Confidence
is still not high on the magnitude of the winds and seas,
however. GFS, GEFS and ECMWF indicate offshore ridging by the end
of the week behind this front for perhaps a day or so of N-NW
winds and lower seas. The ECMWF has another system quickly busting
down the ridge on Saturday with winds switching back to the south
again.
