Area forecast discussion, Dec 6, 2:59 PM PST, 12 hours 5 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
259 PM PST Thu Dec 6 2018
.SYNOPSIS...High pressure will bring mainly clear and dry
conditions though Friday afternoon. A couple of weak weather
systems will bring periods of rain and mountain snow late Friday
into early next week.
&&
.DISCUSSION...Very pleasant conditions are persisting across
Northwest California as upper level ridging develops. Another
night of primarily clear skies will lead to excellent radiational
cooling conditions yet again. Therefore patchy dense valley fog
will be possible across the interior late tonight into early this
morning. Coastal Humboldt and interior Del Norte Counties will
also see patchy frost yet again this morning with relatively light
winds and dry conditions prevailing.
Higher level clouds will be on the increase tomorrow as the next
in a series of systems approach the coast. Mainly light showers
will be possible for locations north of Cape Mendocino Friday
afternoon into early Saturday morning. Southerly winds will also
begin to increase ahead of this system leading to breezy ridge top
winds. The main system will approach the region late Saturday
night bringing wide spread rains back to the area Sunday with the
breeziest southerly winds. A secondary trough will move through
the area Monday morning which will continue the threat for light
showers. Snow levels will remain fairly high (greater than 4500
feet) for these systems. Upper level ridging will re-develop
across the area Tuesday morning bringing an end to the light
showers. Ridging will break down a bit Wednesday which may allow
more light rain to impact the northern portion of the area. /WCI
&&
.AVIATION...Northwest California was dominated by a Ridge of high pressure
today. The result was modest subsidence which caused widespread
drying and SKC conditions over most aviation sites. The exceptions
were across many inland moist valleys and along the rivers. Matter
of fact, UKI dropped into LIFR/IFR this morning. Afternoon model
data indicated brief morning fog redeveloping again along interior
river valleys. The shortwave ridge will give way to another upper
level trough Friday. The associated front will be accompanied by
light rain late Friday evening. Models also show possible LLWS at
CEC towards the later part of this afternoon's TAF period.
/TA
&&
.MARINE...Seas continue to be dominated by a long period westerly
swell. This longer period swell is peaking this afternoon with
wave heights of around 9 to 11 feet at 19 seconds and will very
gradually subside through Friday morning.
Moderate to fresh southerly breezes will develop Friday afternoon
and persist into early next week, particularly across the waters
north of Cape Mendocino. This is in response to an approaching
cold front, and while the inner waters will remain largely
dominated by the westerly swell, offshore areas will begin to see
steeper southerly waves begin to build Friday evening into
Saturday morning. Late Saturday through Sunday, southerly winds
will increase more dramatically across all waters, and may
approach Gale Force in some areas. In addition to the steep
southerly seas that these winds will produce locally, a
reinforcing long period westerly swell will also arrive in the
waters, resulting in a hazardous and chaotic sea state with
multiple wave groups emanating from different directions.
Winds will decrease late Sunday through early next week, allowing
seas to gradually subside. /BRC WCI
&&
.SURF/SNEAKER WAVES...A significant sneaker wave risk is ongoing
along area beaches today as a substantial long period swell
arrives from the west. Local buoy observations indicate that the
swell is peaking this afternoon around 9 to 11 feet at 19
seconds, and only minimal shorter period waves present. This swell
will gradually begin to diminish this evening into early Friday
morning. Swells such as these are known the exhibit substantial
set behavior, and it is this behavior that leads to the sneaker
wave phenomenon. In essence, larger sets of waves will arrive to
the beach after a relative lull than can last for 10 to 20
minutes, which can lull beachgoers into a false sense of security
when close to the surf zone. The arriving larger sets will run
much farther up the beach than expected, and can easily wash
unsuspecting people into the unforgiving waters...particularly on
beaches that have a steep slope. Be sure to exercise caution if
you're heading to the beach today and tomorrow, and be sure to
keep an eye on the ocean and maintain a safe distance from the
surf zone. /BRC WCI
