NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
315 PM MST Sat Dec 20 2014 


..difficult travel over mountain passes expected tonight and 
Sunday... 
..possible winter storm Christmas evening day into Christmas... 


Discussion...a deep moisture plume will bring heavy precipitation 
to the region tonight lasting into Sunday. Areas of light 
precipitation will continue the rest of this afternoon and early 
this evening, ahead of the main surge of moisture set to arrive 
mid evening lasting well into Sunday. Snow levels will gradually 
rise this evening through Sunday with a burst of heavy mountain 
snow initially overnight followed by a change over to a rain/snow 
mix or all rain for many mountain passes below 5500 feet on 
Sunday. Many lower valleys will see a rain/snow mix change over to 
all rain during the early morning hours on Sunday, but a few 
pockets of light freezing rain are possible across the lower 
valleys of northwest Montana this evening...certainly something to 
watch out for. Here are a few specific impacts: 


* Lookout Pass on Interstate 90 will experience heavy and 
relatively wet snow by late evening 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-eyes of over an inch of 
precipitation along Montana Highway 83 between Swan Lake and Seeley 
Lake...elevations above 4000 feet look to receive 3 to 5 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. 


The bulk of the system exits the region by Sunday afternoon, but 
showers will continue through early Monday with unstable northwest 
flow over the region. Models are hinting at the possibility of 
snow bands setting up Sunday night and early Monday, and colder 
air should bring snow levels back to valley floors. This could 
mean a couple quick inches for the morning commute Monday. One 
factor working against snow bands is drying out of the airmass. 
Still, it remains a possibility, and is something we will keep an 
eye on. 


Most of the region will dry out Monday afternoon into early 
Tuesday as weak ridging moves in, giving a window with a good 
chance of improved travel conditions. 


For Christmas eve day into Christmas, we're still looking at a 
possible winter storm which could bring accumulating snow to much 
of western Montana and central Idaho. The problem is large 
discrepancies continue in model forecasts of the center of low 
pressure, and as a result the possible outcomes are anything from 
pass-level only snow event with valley rain to widespread snow at 
nearly all elevations. 


Stay tuned to subsequent forecasts as this system may have 
significant travel impacts for the holidays. Confidence should 
increase in the near future for the actual placement of potential 
snow. 


For Friday and into next weekend, colder and generally drier 
conditions can be expected for the northern rockies, although a 
few waves of energy moving through may be able to create snow 
showers at times, especially over the mountains. 


&& 


Aviation...a very wet system is expected to move in this evening 
and will bring a mixture of rain and snow to area terminals. Most 
terminals should start off as snow or rain/snow mixture but is 
expected to become all rain by Sunday morning. There is also a 
slight chance of freezing rain early Sunday morning at kmso and 
kgpi so temperatures should be monitored closely as it transitions 
to rain. The heaviest bands of precipitation is expected to be 
between midnight tonight and noon on Sunday. During this time 
ceilings will lower and visibilities should be reduced. Rain 
showers are expected to linger through Sunday afternoon.
