from 7 PM this evening to 5 am MST Monday. The Winter Storm Watch
is no longer in effect.

* * Impacts/timing: heavy wet snow will impact area passes this
evening through late Sunday. Heavy snow followed by rain could
make mountain roads very difficult or dangerous to travel on at
times. Lolo and lost trail passes will most likely be
impacted... with impacts also possible at Homestake...
McDonald... and marias passes. Many higher elevation locations
such as Georgetown Lake and Seeley Lake may receive several
inches of snow also.

* Snow accumulations: Lolo and lost trail passes will be most
impacted with expected snow accumulations of 6-12 inches in 24
hours. Homestake... McDonald... and marias passes should see 2-8
inches in 24 hours.

* Locations impacted include... bad Rock Canyon... Essex... Highway
83 Bigfork to Swan Lake... Marias Pass... Polebridge... Highway

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
1046 am MST Sat Dec 20 2014 


Update...Winter Storm Watch is now winter weather advisories 
beginning this afternoon lasting through early Monday. 




&& 


Discussion...12z model runs show similar trends to earlier runs 
regarding the atmospheric river event over this weekend. Periods 
of light snow (mainly over the mountains) are expected to 
continue into this afternoon as moisture overspreads the region. 
There is growing confidence that most mountain passes will see an 
initial period of heavy wet snow later this evening with snow 
levels beginning around 3000ft. Snow levels will then gradually 
rise overnight with some lower elevation passes seeing a rain/snow 
mix or all rain by Sunday morning but passes such as lost trail 
will likely continue as all snow on Sunday. Overall, hazardous 
driving conditions due to snow packed and slick roads are expected 
tonight into Sunday over area passes thus winter weather 
advisories have been issued. 




&& 


Aviation...dense fog will persist at kmso through 20/1500z. Fog 
will gradually lift and clear out at kmso by 20/2000z. Otherwise 
expect cloudy skies with mountain obscurations at times today. The 
next storm system will enter the region this evening and persist 
through Sunday morning. Valley rain will occur at all terminals, 
limiting visibilities and lowering ceilings at times. 








&& 


Previous discussion... /issued 320 am MST Sat Dec 20 2014/ 


.Difficult travel over mountain passes expected tonight and 
Sunday... 
.Possible snow impacts over Christmas evening and Christmas day... 


Discussion...widespread dense freezing fog with 1/4 mile 
visibility or less in the Missoula and central to northern 
Bitterroot valleys will persist through the mid morning hours. The 
fog will slowly begin to lift and scour out by mid afternoon. 


An anomalous moisture plume is still expected to bring heavy 
precipitation to the region by tonight. The first slug of 
moderately heavy rain will arrive across central Idaho by this 
afternoon. Snow levels will gradually rise this evening into the 
overnight. 


* Lookout Pass on Interstate 90 will experience heavy and 
relatively wet snow from after midnight tonight changing to 
either a mixture of rain/snow or just plain rain by daybreak 
Sunday. Lolo Pass will see a similar change to a mixture with 
rain but the timing for that may be a little later Sunday 
morning and then change back to snow by the afternoon. 


* Another area of concern could be the Glacier park area, but with 
strong westerlies aloft, downsloping affects could limit the 
intensity of snowfall and total snow amounts. Nonetheless, Road 
surfaces will be slick at times with snowfall. 


* Models continue to paint a bull-eys of over an inch of 
precipitation along Montana Highway 83 between Swan Lake and Seeley 
Lake...elevations above 4000 feet could see 4 to 6 inches of 
total snowfall through Sunday evening. 


* As the plume of moisture shifts south, Lost Trail Pass will see 
heavy snow for much of the day Sunday and could see a brief 
period of rain/snow. 


Monday and early Tuesday a ridge of high pressure will put a 
brief rest to precip over the region. Valley fog is a possibility 
Mon and Tue morning under this ridge. 


Late Tuesday through Christmas...all models continue to show a 
rather strong and wet weather disturbance moving through the 
northern rockies. The common denominator is that this period will 
be wet but there continues to be a lot of discrepancy on the 
details on where exactly this system moves through the region. 
This is a pattern favorable for significant precipitation or snow 
in a band just north of the surface low pressure. The problem is 
now each model shows a different placement of this low (band of 
precip) anywhere from northwest Montana to central Idaho. 
Models should begin to come into some sort of consistency in the 
next 3 days for confidence to increase enough for details of 
placement and rain/snow amounts potential over the region. 


Stay tuned to subsequent forecasts for this may be a significant 
system and confidence will increase for exact placement of 
potential snow during the critical peak travel over the Christmas 
Holiday. 


Aviation...dense fog will persist at kmso through 20/1500z. Fog 
will gradually lift and clear out at kmso by 20/2000z. Otherwise 
expect cloudy skies with mountain obscurations at times today. The 
next storm system will enter the region this evening and persist 
through Sunday morning. Valley rain will occur at all terminals, 
limiting visibilities and lowering ceilings at times.
