NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
418 am MST sun Dec 21 2014 


..difficult travel over mountain passes expected today... 
..Possible winter storm Christmas evening day into Christmas... 




Discussion...the moist weather system continues to bring a 
variety of impacts today. So far several locations have kept 
enough cold air in place to keep the precipitation type as all 
snow...Highway 83 from Seeley Lake south to Highway 200 including 
Greenough hill all the way to Bonner have experienced at least 4 
inches early this morning. Snow has also been observed near Bull 
Lake, along US-2 from Libby to Marion and also 2 to 4" has fallen 
near Olney north of Whitefish. It's difficult to tell, but 
Lookout Pass has probably seen at least 6" of snow so far with 
snow- covered roads. 


The Camas Prairie and Grangeville area has been experiencing 
strong gusty winds to 50 mph this morning and winds there are 
expected to weaken somewhat towards daybreak. 


Expect the steady precipitation to transition to showers today. 
Strong mid- level winds near 50 mph may be able to mix down 
across portions of southwest Montana especially along Montana-141 north 
of Avon, MacDonald Pass on US-12 this afternoon. These dangerous 
cross-winds could impact high profile vehicles in these areas. 


High pressure will build over the region Monday and Tuesday. 
A few snow showers are expected each day. The biggest impact from 
this ridge will be the potential for fog Monday morning and more 
likely Tuesday morning. 


The ridge will be short lived as a long advertised low pressure 
system will move through the region Christmas eve and much of 
Christmas day. For several days there has been considerable 
uncertainty for timing and strength of this system. It appears 
that models are coming into some agreement regarding timing of 
this storm. This system will first impact northwest Montana 
Wednesday afternoon then slide southward impacting central Idaho, 
west central and southwest Montana Wednesday evening through 
Christmas afternoon. Timing for the best potential for heaviest 
precipitation will be Wednesday evening through midday Christmas. 


How much snow will fall over the area?? much of this question 
depends on snow levels and where the heaviest boundary of precip 
forms. Snow levels will start off fairly low impacting all 
mountains and passes with travel concerns. The big question is 
when will snow levels fall to the valley floors. Models are coming 
into agreement that snow levels will crash to the valley floors 
late Wednesday evening and overnight. Most valley locations should 
wake up to snowfall on Christmas morning. 


Conservative snowfall amounts show anywhere from 4-8 inches in 
the mountains and 2-4 inches in the valleys. This could change 
considerably depending on where the precip boundary sets up, when 
snow levels lower (for valleys) and how long it lingers over an 
area. It would not be surprising if amounts are higher increasing 
travel impacts for Christmas eve and day. Stay tuned to subsequent 
forecast for better timing and location for this system. 


Late this week and next weekend high pressure develops off the 
West Coast leaving the region in a northerly flow aloft. Expect 
scattered snow showers each day with slightly below normal 
temperatures. 


&& 


Aviation...as the steady precipitation turns to showers by late 
this morning there will be some improvement with ceilings and 
visibility. Gusty winds will develop as the atmosphere becomes 
unstable today. Strong gusts near 40 knots are possible near the 
Continental Divide especially from between Helmville and Avon 
south to kbtm this afternoon. Numerous snow showers will be 
expected through Monday across the Clearwater, Bitterroot, Flint 
to Anaconda ranges and from the mission mtns. To Glacier National 
Park...so expect lower ceilings and visibility reductions.
