AREA FORECAST DISCUSSION
National Weather Service Eureka CA
406 PM PST Sun Jan 12 2020

.SYNOPSIS...Unsettled weather will continue through Tuesday across
the region, with periods of light rain and mountain snow expected.
A stronger storm will bring heavy rain, heavy mountain snow, and
potentially coastal hail showers Wednesday and Thursday, with
additional rain possible Saturday.

&&

.DISCUSSION...A weak cold front brought another round of showers
to northwest California this afternoon, although these showers
have primarily only impacted Humboldt and Del Norte counties as of
3:30 PM. Farther inland, showers have struggled to penetrate the
mountainous terrain, with only very weak radar indications of
precipitation east of the Humboldt/Trinity County line. This can
often be misleading due to the marginal radar coverage in these
areas, but regardless it seems that precipitation has been
lighter than expected in northern Trinity County...including high
elevation snow. Still, with the cold front still pushing through
the area, it's possible that some additional precipitation
development is possible over the next few hours, and thus the
Winter Weather Advisory for today across Northern Trinity county
will remain in place for now. If radar trends continue to indicate
that additional snow is unlikely, the Advisory may need to be
cancelled early.

Overnight, precipitation will gradually wind down in most areas,
although some light showers will likely persist through the night
and Monday morning in parts of Del Norte and northern Humboldt
counties. However, a slightly stronger system will bring another
round of moderate rain and high elevation snow Monday afternoon
through at least early Tuesday. Precipitation is expected to be
slightly heavier with this system than it was today, and more
likely to penetrate farther inland. Meanwhile, snow levels are
expected to fluctuate quite a bit, likely from roughly 2000 feet
early in the morning, to 3500 or 4000 feet by mid afternoon, and
back down to 2000 feet overnight and Tuesday morning. As a result,
the heaviest snow accumulations are likely to fall in elevations
above 3500 feet, with more variable slushy accumulations between
2000 and 3500 feet. Despite this snow level uncertainty, many
interior highways will likely see accumulating snow, particularly
the summits along Highways 36 and 3, and perhaps even some of the
summits of Highway 299 and 199. Thus, a new Winter Weather
Advisory has thus been issued for Monday afternoon through Tuesday
morning to account for this threat. Meanwhile, another .50 to 1.50
inches of ran can be expected in Humboldt and Del Norte counties
in low elevations, with .10 to .50 inches elsewhere.

Once again precipitation is expected to reduce somewhat Tuesday
afternoon through Tuesday night, although some light showers may
continue to linger in Del Norte and Humboldt counties through the
night. On Wednesday, yet another storm system will impact the
region, although this storm will be much more significant than the
weekend and early week systems before it. Low pressure is expected
to deepen rapidly Wednesday morning somewhere off the coast of
Oregon as a much colder airmass dives southward from British
Columbia. While there are still some model differences regarding
just how strong this storm will become, there is a high degree of
confidence that a substantial cold front will bring heavy rain
into Northwest CA sometime during the day Wednesday, followed by a
surge in cold air and multiple waves of convective showers late
Wednesday through late Thursday. While rain rates may become
heavy at times, particularly right along the cold front, the more
significant concern will be for the potential of heavy snow. Snow
levels are likely to begin at roughly only 3000 feet on Wednesday,
and will likely drop to as low as 1500 to 2000 feet by Wednesday
night and Thursday. As a result, many interior highways will see
entirely snow during this event, particularly the higher portions
of Highways 3 and 36 where snow may be measured in feet by the end
of the event. Even the summits of Highway 299 and 199 are likely
to see several inches of new snow, with some light snow expected
in some of the higher elevations of Highway 101. Small hail will
also be likely Wednesday night through Thursday night in coastal
low elevations. Meanwhile, gusty southerly winds can also be
expected, although the strength of these winds will likely be
determined by the exact strength and track of the low pressure
system.

Showers will likely diminish Friday morning, but another cold
front may bring additional rain to the region Saturday. /BRC

&&

.AVIATION...A lousy aviation weather day across the region as
another impulse of energy has brought very moist low level flow
into the coast and coastal interior valleys. MVFR conditions have
dominated the day both in vsby and ceiling and periods of IFR have
been observed as well. Subtle improvement is expected this
evening as precipitation frequency should diminish but optimism
should not be high in thinking the cigs will rise much...at least
along the coast. Interior valleys may fair a little better this
evening before ground fog potential increases after midnight.
Another front is expected to approach the coast tomorrow morning
which may end up being very similar to Sunday's weather. /JEF

&&

.MARINE...North and northwesterlies should persist through mid
day tomorrow before another front approaches from the west. This
feature will bring small craft advisory southerlies into the
northern zones and a little lighter wind speeds across the south
zones during the afternoon. Meanwhile a moderate mid period nw
swell continues to plague the waters. Focus will then shift to
Wednesday as a stronger low pressure system and associated front
impacts the waters. Models are really struggling to latch on to
the position and strength of the low that is projected to onto the
central Oregon coast. Recent agreement shows a central pressure
of about 1007mb as it makes landfall. The front which crosses the
waters during the day on Wed should still produce some gale force
southerlies across the outer waters. Did raise the wind speeds
during frontal passage across the inner waters where a few gale
force gusts are certainly possible. Northerlies will ramp up
rapidly behind the front then on Thursday winds will diminish and
become southerly again...as yet another strong system may bring
near gales or gales late Friday night or Saturday. /JEF
