What happened

The episode as NWS PDT wrote it up.

A winter storm lasting from the 10th to the 12th of February brought extreme snowfall to the east slopes of the Washington Cascades and Columbia River Gorge with heavy snowfall for the Columbia Basin, Simcoe Highlands and Blue Mountains. Snowfall totals at Snoqualmie Pass neared four and a half feet over 48 hours resulting in the pass being closed for over 72 hours for snow removal and avalanche mitigation. Just after the initial closure a fatal motor vehicle accident (indirect) occurred near Hyak when a tractor trailer crashed into a concrete barrier. Over 300 vehicles became stranded on the pass when the interstate was shut down. They were eventually led to safety on the 12th of February in a Washington State DOT and State Police convoy. Additional storm total snowfall accumulations of 38 inches at Trout Lake, 15 to 22 inches in the Columbia River Gorge, 8 to 12 inches in the Simcoe Highlands, 10 to 12 inches in the Northwest Blue Mountains and 4 to 6 inches in the Blue Mountain foothills were recorded.

.UPDATE...Big comma head weather system that had and is impacting
the cwa with continued accumulating snow is slowly winding down.
Wrap around moisture was persisting mainly along the wa/or state
line and eastward into the mountains. This short lived...decrease
in pcpn will only be replaced with the next winter storm that is
expected to move into the region tonight with a prolonged period
of accumulating snow. Despite a minor lull in pcpn early
Monday...significant accumulating snow is expected to return
Monday afternoon and night and will likely prompt additional
winter weather advisories and warnings with the next package.

AVIATION...18Z TAFs...Snow has ended at DLS and tapering off at YKM.
IFR/MVFR cigs and vsby in snow will taper off at PSC/ALW/PDT sites
between 18Z-20Z. Conditions will improve at most locations after
20z. The next system will start arriving after 00Z with increasing
and lowering clouds and snow showers starting after 03Z. 93

.PREV DISCUSSION... /issued 337 AM PST Sun Feb 10 2019/

SHORT TERM...Today through Monday night. Very active weather
pattern for the region the next 2 days. Satellite shows center of
upper low along the Oregon coast early this morning. Large area
of enhanced clouds and snowfall over eastern Oregon and southern
Washington. Expect this area of precipitation to continue through
the morning although likely decreasing in intensity by mid
morning. By afternoon the snow should be mostly over the northeast
Oregon mountains as the low continues to move east into Idaho and
Nevada. Strong winds over Washington have decreased and Blizzard
warnings have expired. For the moment all other warnings and
advisories remain as snow is fairly widespread. Another system is
seen on water vapor moving south along the BC coast. This low
will move quickly across the Pacific northwest this evening and
overnight with additional snowfall. A third system will be
approaching from the west. This low and frontal boundary will move
into the Pacific northwest Monday and Mon night. Additional snow
is expected. Temperatures will remain cold through the period
although slight warming is indicated by the models on Mon with a
warm advection pattern. Locally breezy conditions tonight and
Monday as surface lows moving through the area tighten up
gradients. 94

LONG TERM...Tuesday through Saturday...A series of weather systems
will move through during the extended period with cold temperatures
and periods of snow. Tuesday an offshore low pressure system will
move south with a band of moisture spreading snow from southwest
Oregon through central Washington. Wind fields show upslope flow
into central Washington so this may enhance snow amounts. Models
differ Tuesday night and Wednesday. The GFS moves the low east over
WA while the ECMWF keeps the low offshore but does move the moisture
band east over the area. I trended the forecast toward the ECMWF. A
weak upper level ridge will move through Thursday. A few showers
will linger in the mountains. Another system will move into the area
Thursday night and should keep a chance of snow over most of the
area through Sunday.  Coonfield
