.SYNOPSIS...An extended period of wet and colder weather that will
span through next week will begin over the weekend. Significant
mountain travel impacts begin from these systems by early next week
and continue through much of the week.
&&
.DISCUSSION...Shortwave ridging nosing in from the west maintains
dry weather Friday. The pattern begins to change Saturday as a
closed low begins forming off the CA coast. Potent surface impulses
will form and increase rain and winds through the weekend. Models
still struggle with the placement of these surface lows. They may
initially remain quasi stationary, but chances for breezy to
locally strong winds are increasing. The higher end potential
wind forecast from NBM show widespread wind gusts of 30 to 40 mph,
with higher gusts over the ridges and some prominent coastal
headlands.
A stronger and much colder trough will then dive down from the north
Monday. The approaching trough will kick a previously mentioned
surface low eastward into the CA coast Monday. The southern and
eastern periphery of this feature will contain strong winds. Models
have been somewhat consistent with landing it south of Mendocino
County. Even so, enhanced wind will likely span through Mendocino
and Lake counties where wind gusts up to 45 mph will be possible
over the ridges and some coastal headlands Monday.
Winds will increase again over a broader area Monday night and
Tuesday as the cold trough from the north moves in. At the same
time, precipitation rates increase as snow levels quickly lower. Snow
levels are forecast to drop to 2000 to 1500 ft Monday night through
Tuesday morning. There is moderate to high confidence for snow these
snow levels (65% chance for less than 2000ft and 45% chance for
levels less than 1500 ft Tuesday and particularly Wednesday).
Probabilities for levels less than 1000 ft have even increased
(25%), particularly Wednesday. Heavy snow across the higher ridges
above 4000 feet could accumulate from 1 to 3 feet from Saturday
evening through mid next week. Snow totals over the region have
continued to trend higher, so the forecast should be followed
closely. A Winter Storm Watch issuance is anticipated, with advisory
level conditions likely also to be met. Snowfall may continue
through late next week.
Instability will increase Tuesday. Convectively enhanced
precipitation rates may temporarily drive down colder air, lowering
snow levels. This will not be difficult to achieve with 850 mb
temperatures dropping as low as -5C Tuesday. The cold air aloft,
instability, and convective showers will also bring a likely
threat for accumulating small hail Tuesday. Accumulating small
hail over roadways would also pose a significant threat to
motorists.
That said, major travel impacts are likely over much of Trinity
County, and major impacts will also be possible into Humboldt and
Del Norte counties. Travel impacts will also reach the passes of
Del Norte, Humboldt and Mendocino counties, particularly if the
less than 1500 ft elevation snow levels are maintained. Currently,
significant snow accumulations are forecast for highway passes at
locations such as Collier Tunnel, Berry Summit and a good portion
of Highway 36 through Humboldt County. Higher summits on 101 such
as the Laytonville area/Rattlesnake Summit and perhaps even
Prairie Creek Summit will also need to be closely watched for
travel impacts from snow.
Regarding lower elevation rainfall accumulation, NBM probabilities
are predicting a high likelihood for 1.5" to 3" in 72 hours from
early Sunday to early Wednesday morning for most of the CWA, with 3
to 5" in the windward facing terrain. Minor flooding of smaller
river, creeks and streams, urban areas with poor drainage will be
possible, along with sharp rises in some mainstem rivers. JJW

.AVIATION...Stratus has moved inland along the coast bringing IFR to
MVFR ceilings that will last through the morning. Interior valleys
could see fog again this morning as moisture remains available. UKI
has around a 40% chance to see fog this morning. Any stratus and fog
is likely to lift and scatter by late in the morning. High clouds
will also move through the area.
&&
.MARINE...Northerly winds continue to diminish today. Steep
northerly wind waves will continue to diminish as well, but
conditions could still be hazardous to small crafts. A large long
period northwest swell continues to build into the coastal waters,
peaking early today at around 12 ft at 16 seconds. Combined seas
up to 14 ft are possible today.
North winds continue to subside and turn southerly by this afternoon
as low pressure approaches the area. The center of the low pressure
is likely to be off the northern California coast, and the exact
location of the strongest winds is currently uncertain. Strong
northerlies are possible on the western edge of this low with
moderate to strong southerlies possible on the eastern edge. Winds
are likely to remain elevated through the week as the pattern
remains active. There is at least a 30% chance for gales in the
outer waters each day through Friday of next week. JB
&&
.BEACH HAZARDS...A steep, northwest long period swell is building
in, bringing a sneaker wave threat Friday. This swell will peak
around 12 to 13 feet at 16 seconds during the daytime Friday. This
swell will align with beaches in Humboldt, Del Norte, and
Mendocino counties, increasing the threat of sneaker waves. The
wave is expected to produce set behavior with breakers leading to
rapid and unexpected beach run ups of over 18 feet. Calmer winds
and few short period seas along the coastline Friday will further
enhance this danger making waves more sneaky, especially on
steeper beaches. Take care if going to the beach late in the week.
Choose flatter beaches if possible. Stay off of rocks, logs, and
jetties. Never turn your back to the ocean! DS
