What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Seattle, WA wrote its last area forecast discussion before this small craft advisory went out at Jan 15, 4:03 PM PST, 4 hours 58 minutes earlier.

Area forecast discussion, Jan 15, 4:03 PM PST, 4 hours 58 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
403 PM PST Wed Jan 15 2020

.SYNOPSIS...Active weather to continue over the next week. A
strong area of low pressure will continue to bring snow to the
Olympic Peninsula and western Kitsap County locations into the
evening. Scattered snow elsewhere will being to taper tonight.
Strong east winds will peak this evening and gradually ease into
Thursday. Scattered rain and snow showers will continue Thursday
and Friday before the next frontal system affects the area on
Saturday. Saturday will mark the transition back to the typical
winter pattern of periods of lowland rain and mountain snow.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY/...A water vapor analysis
this afternoon continues to reveal a very well organized (and
picturesque!) extratropical cyclone just off the coast of
Washington and Oregon. A sfc low accompanies this system, with 21z
WPC analysis showing a 980mb low center with associated frontal
boundaries extending to its E/SE and S. This area of deep low
pressure has been largely responsible for the sensible weather
impacts today.

Looping MRMS radar imagery reveals a broad swath of precipitation
across the area-mostly stratiform across Washington, with more
convective activity across the offshore waters. Precip (in the
form of mostly snow) initially spread onto the coast during the
late morning hours, where some snowfall accumulation was reported.
Precip (mostly snow) then spread further inland towards Puget
Sound and areas eastward. This would normally point towards a
concerning widespread lowland snowfall event, but there has been
a specific caveat in the forecast. A strong pressure gradient
exists between the offshore area of low pressure and the arctic
high pressure system to the north and east of the region. Pressure
gradient points east to west, leading to the development of
easterly/downslope winds off the Cascades. Downslope winds dry and
warm the lower levels of the atmosphere, which has had several
implications this afternoon. First, drier air, evidenced by
noticeably low dewpoints, caused much of the snow to evaporate
across the lowlands before reaching the sfc- at best some light
snow showers and flurries were able to make it to the sfc.
Stronger snow bands have caused some to panic this afternoon, as
quick bursts of wind-driven snow showers have been reported-but
given the nature of the atmospheric column this afternoon, not
much in the way of accumulation is expected. Continued downslope
winds will lead to the decrease in coverage of the snow showers
through the evening. The large exception to this type of event is
western Kitsap County, especially near Hood Canal. This setup is
favorable for heavy snowfall through the afternoon, with coverage
tapering through the evening. Areas across eastern Clallam and
Jefferson County-and to some extend Port Angeles, have been in a
similar situation this afternoon. Will keep Winter Storm Warning
going for these areas through 6PM this evening to cover much of
the evening commute with continued snowfall. Will likely need an
advisory through the remainder of the evening as this headline
expires.

The winds have been a story themselves this afternoon. Breezy
easterlies have been experienced by nearly all locations in W WA
this afternoon, with the highest sustained speeds and gusts across
the east Puget Sound lowlands and adjacent foothills. Also getting
storm force winds across some of the waters (see marine section).
Gusty winds will cause trees to fall as well as power outages.
Wind gusts within snow showers will also reduce visibility at
times, something to keep in mind for the evening commute. Winds
will peak this evening into the first half of the overnight hours,
before gradually diminishing. All High Wind Warnings and Wind
Advisories remain in effect.

As if wind and snow was not enough, have seen quite the handful of
lightning strikes near the low pressure center and along the cold
front this afternoon, across the offshore waters. Mid level lapse
rates in the vicinity of the cold core low have contributed to
enough instability for isolated thunder. Will keep this going for
the offshore waters and near the WA Coast thru the evening.

Overnight tonight, the strong cyclone will lift north and rapidly
weaken as it becomes absorbed in much larger scale cyclonic flow
across the NE Pacific. Loss of the parent system should lead to
the overall demise of the frontal system and open the door to a
somewhat benign weather day on Thursday. Conditions will remain
unsettled given the disturbed mid level flow, so off and on
rain/snow showers will be possible. Temps will rebound a little on
Thursday, and snow levels will rise a tad. Best chance for a
lowland rain/snow mix or brief changeover to snow showers will be
in the stronger, convective showers.

Yet another weather system is on tap for late Friday into
Saturday. Some details remain uncertain. Temps look to fall a
degree or two and snow levels fall back below 500 feet. If precip
moves in as early as Friday evening/Friday night, could see a
round of at least light lowland snow. Additional accumulation
looks light at the moment. The good news (well, for those tired
of the snow), is that snow levels rise significantly through the
day Saturday. This will mark our return to the more typical PacNW
winter weather characterized by lowland rain and mountain snow.
No river flooding is expected on Saturday, though it's worth an
extra eye on rainfall totals and snowmelt over the Olympics.

Kovacik

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...A fairly active long term
period looks to be in store. Broad scale cyclonic flow will
continue to dominate across the NE Pacific. This will help to
bring weather systems into the area periodically through at least
mid week. The first of which on Sunday may miss us to the north as
a ridge tries to build north from the desert SW. This ridge will
likely be pushed east rather quickly by Monday as a shortwave kick
east across the Pacific. Additional frontal boundaries may bring
rain to the area from Tuesday onwards.

Kovacik

&&

.AVIATION...A strong low pressure system moving over the offshore
waters will support strong southwesterly flow aloft this evening.
Low level offshore flow has increased substantially this afternoon
and could continue to lead to some localized low level wind shear
this evening. The next round of precipitation will continue
through 3Z and will continue as a rain/snow mix. Precipitation
should transition to rain for most terminals by 6Z, with the
exception being KPWT and KBLI. Ceilings will remain VFR to MVFR
with precipitation expected overnight into tomorrow. Some isolated
areas of IFR ceilings and visibility will be possible in snow.

KSEA...VFR ceilings with additional rounds of mixed rain/snow
expected by 6Z. Precipitation should transition to all rain by 6Z.
Surface winds easterly to southeasterly 10 to 20 knots, gusting
to 25 knots at times through the evening hours. SB

&&

.MARINE...A strong surface low and its associated frontal system
will continue to move over the western Washington offshore waters
this afternoon and evening, bringing storm and gale force winds
to the region. Have upgraded the gale warning for the Strait of
Juan de Fuca to a Storm Warning with the afternoon forecast
package to line up with recent wind observations and gradients in
the area. In addition, have upgraded the Gale Watch to a Gale
Warning for the waters of Puget Sound and Hood Canal this evening.
Gale warnings remain in effect for the Northern Inland Waters and
Admiralty Inlet.

Seas will briefly build to near 20 feet tonight and Thursday over
the Coastal Waters. In addition, a coastal flood advisory has been
issued for areas along the inland Puget Sound waters as the
combination of high astronomical tides, low pressure, and wind
waves could produce minor tidal overflow on Thursday morning.

Winds will gradually start to ease as the low weakens and moves
onshore over Vancouver Island on Thursday. Another strong frontal
system will then move through the area Friday night and Saturday.
SB

&&

.HYDROLOGY...An organized frontal system is expected to affect the
Olympic Peninsula Friday night and much of Saturday. With
estimated rainfall totals between 2 and 3 inches, rivers in the
area to expected to rise, particularly the Skokomish. Will also
monitor snow levels during this time period for the possibility
of snow melt. Refer to ESFSEW for further details and continue to
monitor the latest forecast information as the details of the
event evolve.
