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 Spokane, WA wrote its last area forecast discussion before this winter storm warning went out at Apr 10, 4:00 PM PDT, 5 hours 32 minutes earlier.

Area forecast discussion, Apr 10, 4:00 PM PDT, 5 hours 32 minutes before
Area Forecast Discussion
National Weather Service Spokane WA
400 PM PDT Sun Apr 10 2022

.SYNOPSIS...
The Inland Northwest will be under the influence of a cold upper
level weather system into next week. Blustery and windy
conditions are expected Monday and Tuesday. Cold temperatures
will result in snow accumulations on grassy surface at times
through the week. Mountain passes will likely be impacted by snow
at times with winter travel conditions. Temperatures will trend
much cooler next week with several nights of widespread below
freezing temperatures. Lowland snow will be possible across the
Inland Northwest Monday and again Monday night into Tuesday.

&&

.DISCUSSION...

Sunday and Monday: The cold airmass remains unstable this
afternoon and taking a look at the radar that can be concluded
with ongoing scattered snow showers. Temperatures have warmed into
the upper 30s and some low 40s across the region. This morning's
snow band across the Palouse and L-C Valley performed well with
many 4-6" snow reports. Winds generally have been out of the
west-southwest and should begin to see some increases in gusts
into this evening.

As we head into Sunday night and begin looking ahead at the
workweek, here is what we're looking at:

* Wind
* Snow
* Cold Temps

For Monday, winds will begin turning out of the northeast late
Sunday night and by Monday mid-morning winds will become gusty.
Areas of concern with northeast winds will be the far northern
Idaho Panhandle and northeast Washington where the greatest
population of trees pose potential damage and power outage
threats. Sustained winds of 20 to 25 mph and gusts creeping up to
40-45+ mph seem most likely. Probabilities for wind gusts greater
than 40-45 mph are lowest in the valley areas where most of the
population of people live, however the best wind gusts will be
along the higher terrain and the concern I have is for tree damage
and power outages, which in turn affect people. A wind advisory
seems appropriate and therefore will be issued this this forecast
package.

Along with winds, the cold upper level pattern remains in place
with another round of snow possible. Most of the best snow
accumulations will be focused on elevations above 2500 feet. The
area in the eastern Cascades sloping to the southwest (Blewett
Pass, Mission Ridge) towards the southern Cascade mountain range
will see the heaviest snow amounts under a northeast flow. The
Camas Prairie and Blue Mountains will also be an area that sees
additional snow accumulations. And we can't forget the lower
elevations of eastern WA and central ID; some light measurements
on grassy surfaces will be possible.

Temperatures will be chilly this week as we're under the influence
of a northwest flow with an open trough extending into the Gulf of
Alaska. Temperatures will be below/at freezing overnight for
several nights and daytime temperatures will be below seasonal
normal-- don't get too antsy and plant those veggies just yet!
-Dewey

Tuesday through Saturday: The upper level trough will remain across
the region for the remainder of the week. An unstable atmosphere,
with very cold air aloft, will enable the opportunity for spotty
showers throughout the week. Model guidance is indicating an
offshore upper level low approaching mid-week. However, the future
and details of the low is varying between models. With this push of
moisture, the Inland Northwest has the potential for a cold, showery
event to the week. Snow levels will be near surface overnight, so
depending on time of arrival, this could be a widespread snow
event. Many details to be determined with future model runs.

With the stationary trough, temperatures will remain below normal
through the end of the week. An average 5 to 10 degrees below
seasonal, highs will be in the 40s to low 50s with lows in the 20s
to low 30s. JS

AVIATION...
00z TAFs: Snow showers are dotting the eastern WA/northern ID
region this afternoon and will continue through early this
evening. Conditions are fluctuating between VFR and MVFR and will
continue for a few more hours through 04Z. Winds will begin to
increase this evening before shifting out of the northeast
overnight closer to 12-18z Monday. Northeast winds will be
strongest from Bonner's Ferry to Lewiston and into Moses Lake
through the rest of Monday. /Dewey
