AREA FORECAST DISCUSSION
National Weather Service Eureka CA
334 PM PST Mon Jan 23 2017

.SYNOPSIS...Low pressure will slide south along the coast tonight,
which will then be followed by a weak front moving east toward the
region Tuesday night and Wednesday. High pressure and mainly dry
weather is then expected to develop during the remainder of the
week.

&&

.DISCUSSION...Things are winding down throughout the area today as
the last remnants of this week's storm system pass through the area.
The center of this low pressure system remains offshore to our
northwest, and is slowly sliding towards the southeast. Shower
coverage has diminished this afternoon across our more interior
areas, and snow levels have risen enough to greatly improve road
conditions in many areas. However, waves of showers will continue to
move through the area, particularly this evening across Mendocino,
southern Humboldt and southern Trinity counties. Bursts of snow will
be possible with this activity, potentially to as low as 2000 feet
as convection tends to drive snow levels down. Couple that with
cooling that will occur after sunset, and some light accumulations
will continue to be possible through the remainder of the day. As a
result, the Winter Weather Advisory for Southern Humboldt, Southern
Trinity and Northern Mendocino counties has been extended until 10
PM. The advisories in northern portions of the area have been
cancelled as any remaining snow will likely fail to accumulate on
roads. Showers will diminish overnight tonight, but some icy
patches will be possible along interior roads due to below
freezing temperatures. Some valley fog may also develop across
interior valleys.

Weather conditions will be pleasant if not a bit cool tomorrow as an
upper level ridge builds overhead. Another brief period of rain is
expected Wednesday afternoon through potentially Thursday morning,
with minimal impacts aside from potentially some night mountain snow
showers. Conditions will improve dramatically late Thursday through
the end of the weekend as the upper level ridge regains control of
the West Coast, resulting in a warming and drying trend that will
carry through the weekend.

&&

.AVIATION...A deep layer cyclone is forecast to weaken as it moves
south along the NWRN CA coast tonight. This will cause showers to
dissipate across the region, with breaks in cloud cover possible
late tonight. Thus, the probability for enhanced radiational cooling
and fog development will be increased (particularly at Ukiah).

&&

.MARINE...A deep layer cyclone will weaken as it moves south along
the NWRN CA coast tonight. As that occurs, winds will back to
easterly by midnight, and then northerly by noon Tuesday. This
change in direction will be accompanied by a decrease in speeds.
Otherwise, a long period swell (around 15 seconds) with wave heights
to 20 feet will spread east across the waters tonight, with seas
then falling to around 10 feet during Tuesday afternoon. A hazardous
seas warning remains in effect for this swell episode.

Winds will generally remain light through the remainder of the
forecast period. However, another long period westerly swell near 15
feet at 15-20 seconds is forecast to enter the offshore waters
Wednesday night and Thursday.

&&

.BEACH HAZARDS/SURF...Hazardous high surf is still on track through
tonight as a significant swell moves east across the waters. Max
surf heights from 22 to 25 feet will be probable. Another
significant long period swell is forecast to arrive Wednesday
night and Thursday. The threat for hazardous surf and sneaker
waves will increase with this swell.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...High Surf Advisory until 4 AM PST Tuesday for CAZ101-103-104-109.

     Winter Weather Advisory until 10 PM PST this evening for CAZ106-
