Area forecast discussion 
National Weather Service Spokane Washington 
414 am PST Friday Dec 19 2014 


Synopsis... 
a more active weather pattern will continue into early next week. 
Another weather system will bring snow to the mountains with 
mainly rain for the valleys tonight into Friday. A stronger storm 
Saturday into Sunday will bring mainly rain for the valleys...as 
well as mountain snow with rising snow levels. Temperatures are 
expected to remain above average through early next week...before 
dropping down towards normal values by Christmas day. 


&& 


Discussion... 
today through Saturday night...this will be an active and very wet 
period as a pair of storm systems move through the forecast area. 
The first today followed by the second Saturday. This will result 
in measurable precipitation for all locations, with valley rain 
and mountain snow. 


For today and tonight a vigorous frontal system will move through 
the forecast. The warm over-running precipitation moved into the 
region last evening and satellite imagery shows the cold front 
moving onto the Cascades early this morning. This front will cross 
the Cascades around 12z and should be east into Montana by this 
afternoon. So expect drying from the west beginning near sunrise 
then traversing the forecast area through the day. Temperatures 
will be on the warm side with highs around 10 degrees above normal 


* precipitation: yes and for just about all locations. With an 
upper level jet paralleling the front and southerly low level 
flow early this morning even the normally shadowed out lower 
east slopes and deep basin will see measurable precipitation. As 
the cold front moves through the region later this morning the 
flow will shift the focus of the heaviest precipitation across 
the northern mountains and finally the Panhandle mountains this 
afternoon and this evening. Precipitation amounts will range 
from .10-.20 for the low lands with anywhere from .25-.50 for 
the mountains, and possibly as much as .75 near the crest of the 
Cascades. Some showers will linger across the Panhandle 
mountains this evening, otherwise there will be a brief break in 
the wet weather. 


* Precipitation type: warm air advection and southerly flow will 
result in snow levels at or above 3-4k feet for valley rain and 
mountain snow. The area of concern will be for the Methow Valley 
where the cooler air remains trapped, but even there 
temperatures are around freezing or a little more and any snow 
that falls will be wet. So a couple of inches for the Methow 
Valley this morning and 3-6 inches for the mountains above 3-4k 
feet. 


..a strong winter storm expected to result in heavy rain and 
mountain snow across the northwest this weekend... 


Moving on to Saturday and Saturday night...this storm system is 
shaping up to be much wetter as the westerly flow will tap into 
an atmospheric river of very deep moisture. Model guidance has 
been pretty consistent the past several runs showing this moisture 
reaching the Cascades early Saturday morning and over-running the 
remainder of the region during the day Saturday. Isentropic up- 
Glide will be quite impressive and combined with the deep moisture 
means that everyone will get pretty wet. 


* Precipitation: yes and quite a bit. Through the entire event 
the Cascades can expect anywhere from 1-3 inches of liquid and 
perhaps more near the crest. The northern and Panhandle 
mountains .50-1.5 inches and for the low lands around a half 
inch from Saturday morning through Sunday morning. 


* Precipitation type: behind the first cold front temperatures 
will cool down with snow levels dropping down to 2.5-3.0k feet 
across the south and 1.5-2k feet across the north. Strong warm 
air advection will result in snow levels increasing through the 
day Saturday and finally rising above 6-7k feet across the 
south, but still only around 3.5-4k feet across the north. The 
challenge will again be the Methow Valley where the cooler air 
will be tougher to scour out. The models continue to be a little 
too cold for the Methow and I chose to go above guidance in 
these areas, and secondly with this much precipitation and warm 
air advection I would think these areas should mix out pretty 
well. Still there should be an extended period of snow 
accumulation for the Methow Valley with moderate snow 
accumulations possible. For the remainder of the mountain 
valleys it looks like they might start out with a snow/rain mix 
but quickly transition over the rain. Snow amounts in the 
Cascades could be in the 1-2 foot range above 4k feet and up to 
a foot or maybe slightly more for the northeast and Panhandle 
mountains by Sunday morning. The Methow could see as much as 5-7 
inches. 


* Winds: 850 mb winds will climb up to around 40-45kt. The 
question will be if these winds can mix to the surface. Without 
a robust cold front this will be tough. So winds breezy to even 
windy in locations but likely not advisory speed. 


* Temps: very warm for the season with highs in the 40s on 
Saturday and 40-50 on Sunday. This will be 10-20 degrees above 
seasonal normals. Tobin 




Sunday and Sunday night...a cold front plows across the inland 
northwest on Sunday, helping to shunt the bulk of the moisture 
from the atmospheric river south and east of the region. Gusty 
westerly winds will develop by Sunday afternoon and evening with 
gusts to 30 kts. Under the west to northwest flow, precipitation 
will still be confined to the orographic favored areas like the 
Cascades crest, the Blue Mountains and the central Idaho Panhandle. 
Snow levels will be relatively high with mainly valley rain and 
mountain snow. The only exception would be some High Valley snow 
in the far northern valleys Sunday morning, but it looks the 
combination of the winds from the frontal passage and arrival of 
the drier air, will help mix out that colder air and help shut off 
the additional low elevation snow accumulations in the northern 
valleys. Also temperatures look to be warmest of the week on 
Sunday. 


Monday and Monday night..cooler and drier air to filter in from 
the north, giving the region a break from the precipitation. An 
upper level ridge will slowly migrate across the region. A few 
lingering showers are possible by early Monday morning across the 
northern mountains. Expect temperatures to cool late Monday 
night. 


Tuesday through the Christmas Holiday...the ridge aloft flattens 
allowing for a more active period. One weather disturbance will 
drop down from the northwest with a frontal band pushing through 
the region on Tuesday, skipping across the Columbia Basin but 
targeting the mountains. Chances for snow look good for Tuesday 
morning across the northern valleys and mountains, then snow 
levels will jump giving way to valley rain and mountain snow again 
for Tuesday afternoon and evening. This frontal band will slide 
south and stall across the Blue Mountains and southern Idaho 
Panhandle. Meanwhile the models show more energy dropping down 
from the Gulf of Alaska and strengthening the northern jet stream, 
but what they show happens to the frontal band are two differing 
scenarios. The GFS continues the trend that this northern 
disturbance will carve out a deeper trough which digs further 
south and pushes the boundary further into Oregon, and leaving 
much of the inland northwest drier. The 00z European model (ecmwf) bounced back its 
solution and shows the frontal band lifting northward and bringing 
a return of precipitation, mostly in the form of snow, back into 
the inland northwest. To avoid bouncing forecasts around, opted to 
lean more toward climatology gives most areas a chance of snow for 
Christmas eve day, then tapering off by Christmas eve night, 
although confidence is marginally poor. A drier northwest flow 
aloft will move into the region with cooler, more seasonal 
temperatures into the end of the week. /Rfox.

Aviation... 
12z tafs: a frontal system is moving through the eastern portions 
of the area this morning. Light to moderate precipitation will 
effect the eastern taf sites for a few more hours...otherwise 
expect drying from the west. Current VFR/MVFR conditions for the 
eastern zones will begin to decrease MVFR/IFR after 15z as the 
rain comes to an end and fog/stratus develops. Improvement to VFR is 
expected after 22z. Stratus/fog will reform after 06z lowering 
conditions back to IFR. Current IFR/LIFR conditions for kmwh/keat 
may not see as much improvement. Cigs/vsby may increase to MVFR 
at keat after 21z...but the fog/stratus is expected to reform 
around 06z again tonight. Tobin
