Area Forecast Discussion
National Weather Service Spokane WA
232 PM PST Sun Feb 24 2019
.SYNOPSIS...
A moist frontal system will bring continued snow to southeast
Washington into the Central Panhandle Mountains of Idaho this
evening and again on Monday. Moderate snow accumulations are
likely in this area with a chance of light snow elsewhere. Another
system arrives Wednesday or Thursday with a chance of snow.
Temperatures will remain well below normal through the week.
&&
.DISCUSSION...
Tonight through Monday: A positively-tilted trough is dropping
down from British Columbia into the Pacific Northwest today. Of
particular note is an W-E oriented jet streak on the south side of
this trough that is carrying considerable atmospheric moisture
inland. This system's surface low is quickly tracking eastward
across central Oregon, with a relatively narrow plume of snow
slowly drifting northward. As of this writing, the northern fringe
is nearing the Interstate 90 corridor. All told with this system,
a few inches of snow were evident along the east slopes of the
Cascades, and a couple of inches possible along the Palouse
southward toward the Lewis-Clark Valley, Blue Mountains, and Camas
Prairie. Additionally, breezy northeast winds with gusts of 20-30
mph are expected across the northern ID Panhandle, Palouse, and
Columbia Basin with reports of localized blowing and drifting snow
this afternoon.
A brief respite is expected tonight in between storm systems.
With clearing skies and cold advection winds, much of the forecast
area is projected to drop down into the single digits and lower
teens tonight.
The next wave then reloads, first impacting SE Washington and the
central ID Panhandle early Monday morning and slowly lifting
northward through the day. This feature looks to be a bit stronger
and wetter than today's, and winter weather highlights have been
issued to address this. This system's northward track will again
be limited by drier, gusty northeast winds across the northern
portions of our forecast area. These gusty northeast winds will
likely cause some patchy blowing and drifting snow Monday
afternoon and night in similar wind-prone areas. Energy with this
system will begin to move eastward Monday night into Tuesday
morning.
Dang
Tuesday through Thursday night...The cold pattern continues with
continued upper ridging in the eastern Pacific and a cold upper
trough over the Inland NW. On Tuesday one system exits with
lingering show showers mainly over the Idaho Panhandle. The next
system in the form of a closed low off the WA/OR coast will send
another shot of moisture into the area but models showing
significant timing differences as well as placement of highest
snowfall. The GFS and the GEFS once again favor SE Washington into
the Central Panhandle Mountains both Wednesday and Thursday while
the ECMWF and Canadian show a more widespread light to moderate
snow over the region Wednesday shifting into the Idaho Panhandle
Thursday. With the National Blend of Models supporting more of a
ECMWF/Canadian solution the forecast leans this way but confidence
is low. Given the uncertainty mainly chance POP's were utilized
for Wednesday and Thursday. With the low off the coast and cold
arctic air over southern BC and along the Rocky Mountain Divide
north to northeast winds will continue with breezy conditions at
times. These winds will continue to usher cold air into the region
with highs in the mid 20s to lower 30s for most towns with lows
in the single digits and teens. These values are about 15 to 20
degrees below normal. JW
Friday through Sunday...
It looks like the tail end of snow will be moving through the
Idaho Panhandle by the end of the day Friday. Following, we may
get a break from the snow this weekend with drier weather.
However, it doesn't look like it's going to be warming up soon.
The below-normal temperatures will continue into the weekend with
the north- northwesterly flow bringing the cold air from Alaska.
The highs will remain in the mid-20s to mid-30s & lows in the
teens.

.AVIATION...
18Z TAFS: An east-west oriented storm system is currently moving
through the region. At this hour, snow is bringing IFR conditions
to KPUW-KLWS-KEAT, and will likely continue through around 00z
before dissipating. KGEG-KSFF-KCOE-KMWH will be on the northern
fringe of this system, and VFR conditions may briefly deteriorate
to MVFR this afternoon. The next round of snow will likely start
impacting KPUW-KLWS around or after 12z tonight. Anything which
falls will be quite light and fluffy and subject to some blowing
as N-NE winds increase through the day.
