What forecasters said that day

The local office's own words before this winter storm warning 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 winter storm warning went out at Feb 16, 9:58 AM PST, 45 minutes earlier.

Area forecast discussion, Feb 16, 9:58 AM PST, 45 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
958 AM PST Fri Feb 16 2018

.SYNOPSIS...A broad trough of low pressure will pass southeast
through Western Washington today. Windy conditions and heavy
mountain snow are expected Saturday as a deepening surface low
tracks southeast down Vancouver Island and then across to
northeast Washington. On Sunday, a modified arctic cold front will
move southward through the area, bringing the possibility of
lowland snow, as well as strong wind. It will be followed from
late Sunday through Tuesday with dry weather but some of the
coldest air so far this winter.

&&

.SHORT TERM...Active and potentially impactful weather coming up
this weekend, first on Saturday in the form of wind and heavy
mountain snow, then on Sunday with the potential for lowland snow
and strong northeast-north Fraser Outflow wind. Coldest air mass
of the winter is expected from Sunday night through Monday night.

Though today's weather is not insignificant, it is the lesser
concern compared with Saturday, Sunday, and beyond. The current
round of Winter Weather Advisories in the Cascades is verifying
well. Precip and wind will generally be on a decreasing trend for
the rest of today, as a broad trough of low pressure in northwest
flow aloft exits.

On Saturday, a deepening low pressure center will move southeast
down Vancouver Island, then track east near Vancouver B.C. and
continue deepening as it moves to northeast Washington. At it
closest approach, the central pressure of the low will be near 998
mb. Strengthening or deepening lows typically come with more lift
and greater impact. The low will be preceded by a large swath of
warm advection lift, while northwest flow aloft is a great
direction for enhancing orographic lift and snowfall totals over
the Cascades, including the main highway passes. Some of the
heaviest snow totals in the passes come in this type of pattern.
Will be issuing a Winter Storm Warning for the mountains for
Saturday in the next hour or so. One to two feet or more of snow
seem likely. Avalanche danger will be elevated given the heavy
snow and wind.

Southwest gradients will really pick up as the low makes it
closest approach around mid-day Saturday. Models bring the HQM-SEA
gradient to around +4 to +4.5 mb, and the UIL-BLI gradient should
reach near +5 mb around mid-day Saturday. GFS MOS peaks the
sustained wind at Shelton, Tacoma Narrows, Tacoma McChord, Sea-
Tac, and West Point (Discovery Park) at 34, 28, 31, 27, and 34
knots respectively in the southwest wind mid-day Saturday. With
925 mb winds of 40-50 knots and cold advection during this period,
wind gusts of 45-50 mph are totally reasonable for the South and
Central Sound regions. Further north, a strong westerly surge is
expected through the Strait during the afternoon. NW flow aloft
favors such surges impinging on land areas on the U.S. side of the
Strait and the Admiralty Inlet area. Given all these things, have
gone with a round of Wind Advisories for tomorrow. Would not be
surprised if one or two zones pick up a few stronger gusts.

After the low exits east on Saturday night, a cold front will
spread out of B.C. into Western Washington on Sunday morning,
aided by strong Fraser Outflow wind. The Bellingham to Williams
Lake gradient could exceed -20 mb on Sunday morning, making this a
strong outflow event. May eventually need a High Wind Warning for
Western Whatcom County on Sunday. This pattern will cause a sharp
modified arctic cold front to slip southward. The air aloft will
be cold, so low-level convergence near the frontal boundary and
some instability could support snow showers as the front moves
south. The Port Angeles area is most likely to get snow, given
northeast wind upsloping along the north-facing side of the
Olympic Mtns. The Puget Sound lowlands should get spotty
accumulations of an inch or two. Emphasis on "spotty", meaning
some places will miss out altogether. The latest UW-WRF model
paints the more widespread areas of snow from Tacoma and Shelton
on south through Lewis County. Haner

.LONG TERM...From Previous Discussion: Monday and Tuesday will be
dry but chilly with northerly flow aloft. Fraser outflow will
ease but modified arctic air will linger over the area. Highs will
be mostly in the mid to upper 30s and lows will be in the 20s
with some teens in spots. Some of this will depend on if there is
any snow on the ground from Sunday. A weather system will drop
down from the north later Wednesday or Wednesday night for another
chance of rain or snow. Schneider

&&

.AVIATION...Strong northwest flow aloft will continue into the
weekend. A cold front moving through the interior this morning
will push east of the area midday. Rain out ahead of the next
much stronger system will reach the area overnight.

Ceilings are on the edge of IFR and low end MVFR this morning.
Expect ceilings to improve into the higher end of MVFR this
afternoon as onshore southwest flow increases. Showers along the
coast and in the interior from KSHN-KOLM southward, in the
interior from around KBLI to KAWO, and snow in the mountains will
diminish as the front moves off to the east this afternoon.

Widespread MVFR conditions will continue later tonight into
Saturday morning as rain ahead of a low pressure system that will
move eastward across northern portions of the area Saturday
afternoon. Albrecht

KSEA...Low end MVFR ceilings through midday. Slight improvement in
the ceilings this afternoon and evening into the 2000-3000 foot
range. Southerly winds 12-15 knots with gusts to 25 knots through
early this evening. Winds easing back down to 5 to 10 knots later this
evening. Southwest sustained 20-30 knots with gusts to 40 knots
will develop about 18Z Saturday and continue into Saturday
afternoon. Albrecht

&&

.MARINE...A cold front moving southeast through the inland waters
this morning will push well east of the area this afternoon. Small
craft advisory west winds are occurring in the Strait of Juan de
Fuca and will develop over Puget Sound and Hood Canal midday.

Winds will diminish this evening between systems. Then a 996 mb
low will move southeast across northern portions of the area
Saturday afternoon. Expect widespread gales to develop from the
west starting early Saturday morning. Gale watches are in effect
for all waters except Puget Sound and may be upgraded to warnings
this afternoon. There is a chance that a gale warning may need to
be issued for Puget Sound and Hood Canal after evaluating more
data.

Strong northeast Fraser outflow wind will spread out across the
waters starting late Saturday night and continuing into Sunday
night. Expect gales over the northern inland waters, the strait,
and the coastal waters with the outflow. Near gale conditions are
expected Sunday afternoon and evening through Admiralty Inlet and
in the northern portions of the Puget Sound waters.

Gradients will ease Sunday night and become light by later Monday
into Tuesday. Albrecht

&&

.HYDROLOGY...River flooding is not expected for the next 7 days.
