..difficult travel over mountain passes expected Saturday night 
and Sunday... 
..possible snow impacts over Christmas evening and Christmas day... 


Discussion...snow and rain have started falling lightly across 
the northern rockies already today, and will continue 
intermittently through the day Saturday. 


Saturday evening the precipitation really starts to increase as 
an atmospheric river of warm, moist air streams into the region. 
Snow levels will start around 3,500 feet and start to rise 
Saturday night to around 6,000 feet in some locations by Sunday 
afternoon. This is expected to cause very difficult travel 
conditions over mountain passes with heavy wet snow followed by 
rain at times. The ample moisture from the atmospheric river will 
cause high precipitation rates at times, which in turn may cause 
heavy snow. There is still considerable uncertainty with the 
timing of snow level changes, and this coupled with the high rate 
of precipitation could cause very big errors in the snowfall 
forecasts near the pass levels. As a result, a winter weather 
watch has been issued that includes all the area passes for 
Saturday night through Sunday. As the storm approaches and we 
become more confident of snow levels, the watches may transition 
to warnings for the high impact areas and advisories elsewhere. 


Meanwhile, confidence is high that there will be a lot of snow at 
the highest elevations. Above 6,000-7000 feet, snow amounts in 
the Bitterroot, Clearwater, and portions of the mission and Swan 
ranges will be measured in feet. 


Sunday night into Monday, snow showers will linger behind a weak 
cold front associated with the system, with snow levels falling. 
Due to the warm nature of the atmospheric river, very little snow 
is expected in the valleys. 


Looking ahead to the Christmas Holiday, forecast models are 
showing a potent storm tracking through the northern rockies 
Christmas eve and into Christmas day. This storm will have the 
potential to bring accumulating snow impacting travel. There is 
still a great deal of uncertainty however as various models are 
tracking the surface low pressure center hundreds of miles apart, 
and they are also varying from run to run. These different tracks 
could result in anything from snow at valley floors to only at the 
higher elevations. We will be keeping a close eye on this storm, 
and should be able to provide better information as we get closer 
and forecast certainty increases. For now, be aware that Holiday 
travel may be impacted. 


Colder air will move into the area behind the Christmas storm, 
pulling temperatures across the northern rockies below freezing. 
Temperatures will be cold, but not exceptionally so (mostly just 
colder than what we've seen recently). 


&& 


Aviation...intermittent showers will continue through the evening 
and tomorrow. Expect mountain obscurations with variable ceilings 
and moderate visibility restrictions. Precipitation will be mixed 
this afternoon becoming mostly snow tonight. Kgpi will be most 
impacted by visibility and low ceilings at times, though all area 
terminals will be affected.
