Area forecast discussion 
National Weather Service Spokane Washington 
230 PM PST Tuesday Nov 25 2014 


Synopsis... 
mild and wet conditions will continue through Thursday. Snow 
levels will be on the rise tonight...but expect some 
accumulations for the areas near the Canadian border through 
morning. Thanksgiving will be breezy...wet and continued warm. 
Then a colder weather pattern is expected for the Holiday weekend 
with the mountains receiving several rounds of snow. Snow levels 
will fall to valley floors by the weekend. 


&& 


Discussion... 
tonight and Wednesday...the ridge of high pressure that built into 
the region on Monday and overnight was pushed down by a short 
wave disturbance moving over the top of the ridge this morning. 
This did two things, first it pushed the moisture further south 
over the southern zones today and second it allowed cooler and 
drier air to filter into the northern valleys. For tonight and 
Wednesday that front will push back to the north. This will 
increase the precipitation potential across the northern zones and 
begin to dry conditions out across the southern east slopes...the 
basin and portions of the Washington Palouse. 


*Precipitation: yes and plenty of it outside the Columbia Basin 
and lower east slopes. The lower elevations will likely see .10 
to ... northern mountains from a quarter to a half 
inch...the Panhandle mountains from a half to just under an 
inch...and for the Cascades anywhere from about half inch to 
almost 2 inches. 


*Snow levels: currently snow levels are pretty high over the forecast 
area...between 4k-5k feet and with additional warm air advection 
they should remain high. So precipitation will be as rain. The 
exception will be across the northern mountains and dropping 
south along the Panhandle where the cooler and drier air moved 
in. Many of the valley locations will most likely wet-bulb 
(evaporative cooling) to right around freezing and the some of 
the valleys up near the Canadian border may see wet snow 
accumulation of 1-3 inches overnight. The mountain will locally 
pick up 5-8 additional inches. So the Winter Weather Advisory 
will be extended through Wednesday morning and issued down to the 
valley floor. A bigger challenge will be Shoshone County. For the 
most part snow levels are above 4-4.5k feet. A nose of cooler air 
has remained in the vicinity of Lookout Pass. I has been snowing 
up there all day and new guidance indicates that snow level for 
that area will not rise above pass level until after 12z so that 
advisory will also be extended...but mainly for the look out pass 
area. 


*Temperatures and winds: temperatures will remain mild through the night 
with highs on Wednesday in the 40s and 50s. Winds will increase 
through the night out of the southwest 10-20 mph with gusts to 25 
mph. Tobin 


Wednesday night through Friday night...an active and mostly wet 
rather than white period is in store for this time frame. Pacific 
satellite reveals a nearly stationary closed low way off the 
Pacific coast in the southern Gulf of Alaska with an upper level 
ridge ahead of it. Models are in good agreement and consistent 
over previous runs in keeping this low offshore...but the issue 
will be interplay between a currently ill defined short wave 
dropping down the coast of the Alaska Panhandle right now...and 
the deep fetch of subtropical moisture feeding ahead of the 
Pacific closed low. The descending wave will flatten the current 
ridge and direct the moisture feed directly into the forecast 
area beginning Wednesday night and continuing through Friday 
evening. Finally by late Friday night another shot of very dry 
modified Arctic air will be drawn into the region behind the 
passage of the northern wave. The GFS model is more aggressive 
with the evolution while the ec is slower. The European model (ecmwf) appears to be 
more consistent over a series of previous runs and this model was 
used as the basis for the forecast. 


All of this reasoning adds up to a wet forecast as the moisture 
plume feeds into the region...but there will likely be a 
perceptible rain shadow in the Cascades Lee as the mid level flow 
remains westerly...but this will also enhance precipitation into 
the Idaho Panhandle and northeast Washington mountains. Snow 
levels will stay very high in the warm advection pattern ahead of 
the swooping coastal short wave. The best chance for a back fill 
into the basin of significant rain will be on Friday as the main 
fetch is enhanced along the cold front leading edge of the the 
Arctic air. Storm total precipitation totals through this 48 hour 
period will range from upwards of 2 inches on the high Cascades 
and northeast mountains (although much of this above 6000 feet 
will be locked up as snow) to 1/2 to 1 inch of rain in the 
valleys of these regions...to 1/2 to 3/4 of and inch of rain over 
the rising terrain of the East Basin and a tenth or two in the 
deep basin. 


Persistently breezy and potentially gusty southwest winds will 
also characterize this period...with all models indicating a 
slowly drifting but strengthening surface low pressure over 
southern British Columbia promoting a tight southerly gradient 
over the forecast area with a strong potential of mixing stronger 
winds aloft down to the surface during the daylight periods. 


Snow levels will crash Friday night from north to south...but by 
this time the air mass will be aggressively drying out with the 
only significant accumulations expected in the Idaho Panhandle 
mountains above 3000 feet or so. 


So...in general a raw...windy and wet pattern with relatively mild 
temperatures is expected through Friday with a Stark cooling trend 
Friday night. /Fugazzi 


Saturday through tuesday: period looks to have a variety of 
weather including both periods of both dry and wet conditions. 
We will start the weekend off with a Continental polar front 
dropping out of Canada ushering in much colder and drier air to 
the region. This will bring an end to the precipitation chances 
quickly for the north and central portions of the area as 
dewpoints drop to the floor and skies begin to clear from north to 
south. As the colder air rushes in, we may have the chance for 
some snowfall especially in the southern portions of the forecast 
area Saturday as enough moisture remains to promote rain and/or 
snow. The set up is similar to an event we saw earlier this year 
as the cold polar air will be battling the moist Pacific air and 
along the boundary is where the best precip chances will be. For 
the weekend it looks to stay in far southern WA, the southern 
Panhandle and mainly Oregon. As the cold air advects in from the 
north we will also see our winds increase as cold air advection 
coupled with the downsloping topography of the region supports it. 
The winds are something that will have to be further examined to 
get a better idea of the magnitude we could be looking at. Usually 
with cold air intrusions such as this we see pretty good amounts 
of wind especially though the Purcell Trench, the Okanogan Valley 
and also in the West Plains and Columbia Basin. 


Now we will move to the more exciting part of the forecast as the 
moisture tap shifts from the mentioned southern areas back across 
a larger portion of the region. This shift looks to start late 
Sunday into early Monday as the Pacific moisture overpowers the 
Arctic air. Both the GFS and Euro depict the moist air overrunning 
the cold air in place allowing for what currently looks to be a 
widespread snow event. This could potentially mark the first 
significant snow event for many valley locations. Confidence is 
moderate at this point as their is good model agreement in the 
overall pattern and both would support a temperature profile for 
snow for the majority. The one thing to watch would be the amount 
of warm air that enters. Currently the GFS is quite cold at the 
surface with wetbulb zero temps are well below zero for all of the 
region. The Euro brings a good surge of warm air Monday that could 
lead to a switch to rain for the lc valley, the southern basin and 
portions of the Palouse. With models diverging at this point I 
went for a compromise leaving snow for most with a mix in the 
lowest southern valleys. How long the snow will last or how much 
each area receives is currently still in the air as models are 
wavering a bit. A lot of this will depend on the strength of a 
ridge in the central part of the country determining which areas 
see the best quantitative precipitation forecast amounts. The exact details of this will have to 
wait, but for now many areas could get a good taste of winter.

Aviation... 
18z tafs: little change to the previous forecast discussion as we 
expect a pretty steady rain today south of a line from the north 
Cascades to near or just south of Mullan Pass. Expect 
precipitation to shift back to the north this evening and 
overnight. Snow levels keep precipitation as rain at all taf 
sites. The abundance of moisture will result in stratus and some 
fog for the taf sites with conditions wildly fluctuating between 
MVFR to VFR/LIFR and back as bands of heavier precipitation moves 
through the region. Southwest winds will be on the increase 
overnight with gusts 15-25kts.Tobin
