AREA FORECAST DISCUSSION
National Weather Service Eureka CA
420 PM PST Mon Dec 12 2016

.SYNOPSIS...
Widespread heavy rainfall will return to all of Northwestern
California over the next few days, as a series of storm systems and
associated surface fronts cross the region. Additionally, some
higher elevation snowfall is likely, especially in the Thursday
through Friday time frame. Dry weather will return for the area by
Sunday.

&&

.DISCUSSION...

.SHORT TERM...
(Today and Tonight)

The calm before the storm is one way to describe the next 18 hours.
Some interior valley fog, similar to what we seen this morning, may
develop once again. Confidence in it being as widespread wasn't high
enough to include in the zones at this time, but this is something
we'll take another look at this evening with the next set of the
numerical model runs. Otherwise, expect light winds and another
seasonably cool night overnight.

.LONG TERM...
(Tuesday through next Monday)

The models remain consistent, as they show an atmospheric river
setup developing for the next few days. Precipital water values
nearing 1.5 inches, which are near the 95th percentile from a
climatology standpoint for this time of year, will bring very heavy
rainfall to the area. The models continue to show a pair of storm
systems with a few surface fronts crossing the region during this
time. The first surface low looks to affect us in the Tuesday
through Wednesday time frame, as a strengthening surface low passes
by to our northwest, before making landfall along the central Oregon
coast. A warm front with very good surface convergence and 850mb
Theta-e advection also show a heavy rain signature in the model
forecasts and soundings. Overall, we can expect to see rainfall
totals of 1 to 3 inches (locally higher) with this first system.

As the first system passes by, yet another surface low and attendant
warm and cold front will cross the region, riding along a stalled
front that looks to reside just offshore. This next surface low
looks to move from Humboldt Bay to Orleans early Thursday afternoon.
A warm front ahead of this low and a cold front following its
passage will both focus widespread heavy rainfall, with this next
round looking to drop 3 to 5 inches in Thursday afternoon through
early Friday morning. This system will be moisture laden as well,
with PWATs running in the 1.2 to 1.4 inch range. Given the moist
soil conditions from recent rainfall, and after coordinating with
all surrounding forecast offices and our national Weather Prediction
Center, we hoisted an Areal Flood Watch for the entire forecast area.

As for any higher elevation snowfall, snow levels running in the
3000 to 4500 feet range north of highway 299 may allow some minor
accumulations to develop Tuesday into Wednesday. The more
significant snowfall potential looks to be in the Thursday through
Friday time frame,a s colder air filtering into the region drops
snow levels into the 1500 to 3000 feet range. Sufficient moisture
will linger for a few inches of snowfall to develop, and a Winter
Weather Advisory may need to be issued over the next few days. /PD

&&

.AVIATION...
Airfields across Northwest California will experience brief drying-
out and VFR cigs/vis through the rest of today/tonight. A few
pockets of patchy fog may form at the coast...but will not be
pervasive. After a sufficient amount of rain...inland valleys &
river valleys had widespread IFR conditions this morning...Ukiah
even reported cigs as low as OVC001 and vis less than 1/4 mile.
Lower cigs/vis possible again in the A.M. across interior valleys
but not expected to be as widespread. Across the entire region:
Increasing clouds and rain chances starting early Tuesday, mainly in
the southern areas as a warm front moves into the region and slowly
drifts northward through the day. By late afternoon/early evening to
mid evening, Most airports/airfields across the area will be
inundated with at least light rain. Light snow will be possible at
the much higher terrain landing strips. /TAA

&&

.MARINE...
Light winds will continue through Tuesday afternoon
across the coastal waters. A deepening surface low will approach the
area Tuesday night and move just N of the area on Wednesday. Ahead
of this surface low, a winds in the lower levels of the atmosphere
will rapidly increase with southerly gales developing Wednesday
afternoon and evening. Wind gusts to near storm force are possible
over the extreme N portion of the area Wednesday evening. Short
period seas will increase in kind. Moderate to heavy rains will
spread across the marine zones Tuesday night and continue into
Thursday.

Winds will shift to the NW and diminish behind the front, but likely
remain near small craft advisory criteria. Winds will likely remain
gusty in the NW flow due to cold air advection and turbulent mixing.
/SEC

.COASTAL ZONES...
Perigean spring tides will continue through
Thursday. High tides will be between 8.5 to 8.7 feet each morning
near North Spit in Humboldt Bay. When the tide reaches 8.8 feet or
higher, there is the potential for coastal flooding. Lately, tidal
anomalies have been running around 0.3 to 0.6 feet above normal.
These deviations added to the forecast tide yield a potential tide
in excess of 8.8 feet during the late morning hours through
Thursday. Another coastal flood advisory has been issued for
Humboldt Bay from 8 am until 12 pm on Tuesday.

More significant coastal flooding is possible on Wednesday as S
winds and waves increase and rainfall from the land runs off into
the adjacent bays. A coastal flood watch/warning may be needed for
this period. /SEC

&&

.HYDROLOGY...
Given the rainfall forecast described above, it's no surprise the
latest guidance from the River Forecast Center shows several rivers
going into the monitor or flood stage. At this point, the Eel River
and Navarro river look to be at highest risk for flooding. Some rock
or land slides will be at least a moderate potential as well, should
these forecasted rainfall amounts /intensities verify. /PD

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...Flood Watch from Tuesday afternoon through late Thursday night
     for CAZ101>113.

     Coastal Flood Advisory from 9 AM to 1 PM PST Tuesday for CAZ103.

NORTHWEST CALIFORNIA COASTAL WATERS...Coastal Flood Advisory from 9 AM to 1 PM PST Tuesday for PZZ410.
