NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
225 PM PST Sat Jan 31 2015 


Synopsis... 
a frontal system will bring light snow to much of the region on 
Sunday. Another front is expected on Monday, and it should bring 
rain and mountain snow. More warm and wet weather disturbances are 
expected next Thursday through Saturday to end the nest work 
week. 


&& 


Discussion... 
tonight through Sunday night... 


..light to moderate snow accumulations for northeast Washington 
and north Idaho on Sunday... 


A large low parked in the Gulf of Alaska will send a moist frontal 
system across the inland northwest on Sunday. Precip looks to 
begin in central and eastern Washington early to mid 
morning...reaching the Idaho Panhandle late morning. This system 
has a subtropical moisture tap...which combined with increased 
isentropic lift will result in widespread rain and snow...except 
for possibly Wenatchee and Moses Lake where the lift will not be 
as strong with westerly flow resulting in downslope off the 
Cascades. With widespread stratus over most valleys holding temps 
in the lower to mid 30s this afternoon...this will help keep snow 
levels low initially. Then in the afternoon with no strong 
surface development with this system...winds look to remain light 
with little to no rise in snow levels as steady precipitation 
helps keep the column cool. Wet bulb zero heights would suggest 
the snow from the Waterville Plateau to Spokane to Kellogg north 
to the Canadian border as well as the higher portions of the 
Palouse...with Rain/Mountain snow south of these areas. Low level 
upslope flow into the higher terrain of NE Washington and north 
Idaho will result in the highest accumulations around Deer Park, 
Elk, Sandpoint, Coeur D'Alene and the central Panhandle mountains 
with valleys receiving 1 to 3 inches with as much as 4 to 8 inches 
in the mountains. However with afternoon temperatures in the lower 
30s roads will probably become slushy...but may become slick again 
Sunday evening after sunset. While amounts are marginal for an 
advisory...we will issue one to heighten the winter weather 
potential for those traveling for the "big game." Jw 


..more warm and wet weather is expected through the work week... 


Monday through Tuesday...the models are in pretty good agreement 
that weak ridging will be over the region. The resultant 
southwest flow will allow another frontal passage to move through 
the forecast area Monday morning with the following weak warm cold 
front following Monday afternoon/evening. This will be a near 
repeat of the Sunday/Sunday night event. Forcing will not be 
overly impressive, but moisture will with pwat's over 200% of 
normal. The big difference will be that the warm advection is 
slightly stronger and snow levels are expected to rise. Snow 
levels Monday morning will be around 4k feet across the southern 
zones and 2-2.5k feet across the north, but should rise through 
the day to near 5k feet south and near 3k feet across the north. 
As such we expect mainly rain across the southern zones. North of 
the Columbia/Spokane rivers the valleys may begin as a rain snow 
mix but should turn over to rain through the morning. Snow will 
prevail for the mountains above 3-3.5k feet. 24 hour snow amounts 
for the northeast and Panhandle mountains will be 3-6 inches and 
locally higher. For the Cascades 4-8 inches will be possible with 
more possible near the crest. Drying from the west is expected 
behind the cold front Monday evening for break in the weather 
action. The exception will be for the crest of the Cascades and 
the Panhandle mountains where up-slope flow will keep higher pops 
in the forecast. 


Wednesday through Saturday...the models begin to diverge at this 
point. All the medium range models show high pressure building 
along the coast Wednesday and moving inland Thursday and Friday. 
This keeps a warm and very moist southwesterly flow pointed at the 
pac northwest. Differences show up in timing of any individual wave 
moving through the flow Wednesday and Thursday and generally broad 
brushed chance for precipitation through this period. Guidance is 
in better agreement showing a better of precipitation Thursday 
night through Saturday. Precipitation amounts to end the week 
could be quite impressive. Moderate warm air advection will not 
only result in warming temperatures but also big rises in snow 
levels. By Friday snow levels will be 5-6k feet with snow only at 
the highest elevations and rain for all of the valleys. One thing 
we will have to keep an eye is the potential for freezing rain 
Thursday night and early Friday as the precipitation type 
transitions form frozen to liquid. At this time the greatest 
potential will be for the valleys of the east slopes of the 
Cascades and to a lesser degree portions of the Okanogan Valley 
and the Okanogan Highlands. We will have a better idea as we get 
closer to the event so stay tuned. 


Temperatures in the mid 30s to mid 40s on Thursday are expected 
to warm into the mid 40s to mid 50s. Tobin

Aviation... 
18z tafs: light snow or flurries should be on the decrease by 20z 
around Spokane as low pressure system dives into Montana and 
Wyoming by this afternoon. With the upper level ridge rebounding 
this afternoon following the passage of the Montana system, look 
for the stratus deck to persist through the taf period. The 
inversion layer may lift and drop today and tonight causing 
ceilings to rise and lower. In general, ceilings at most sites are 
expected to be in the 800-2000 ft range. The next system will move 
into the area on Sunday...with -sn expected to develop in the 
Cascades late tonight or early Sunday morning with -sn or -rasn 
possibly developing at the taf sites between 15-18z. Jw
