Area Forecast Discussion
National Weather Service Missoula MT
320 PM MST Sat Feb 4 2017

...ANOTHER ROUND OF SIGNIFICANT SNOWFALL TO IMPACT NORTHWEST
MONTANA SUNDAY THRU MONDAY...

.DISCUSSION...Periods of light snow will continue to fall across
much of the Northern Rockies through the rest of today and
overnight. Total accumulations will be generally light, being on
the order of 1 to 3 inches. However some locations near the Idaho
and Canadian border may see up to 5 inches by Sunday morning. And
that's when things get really interesting.

Forecast models are coming into much better focus regarding a
potentially significant period of very heavy snow that will
develop across NW Montana beginning Sunday afternoon. The synoptic
set up is, quite frankly, textbook to support heavy snowfall. The
combination of:

1. Strengthening low pressure at the surface over Eastern
Washington,
2. Deepening southwest mid-level flow responsible for transporting
relatively warm, moist air into the region,
3. An approaching dry, arctic cold front crossing the Continental
Divide,

This will all result in what could be some of the most impressive
single storm snowfall amounts thus far this winter. Snowfall
rates of 1 to 3 inches per hour for several hours are quite
possible in places like Libby, Kalispell and West Glacier with
travel significantly affected along US-2 and US-93. Valleys
throughout the Glacier region could see upwards of 3 feet with
Marias Pass tipping the scale at around 4 feet of snow! All of
this in a matter of 36 hours. Needless to say, the snowfall from
this storm will be very significant. Add in the possible
combination of wind from the arctic air mass and we may even see
blizzard like conditions for a time on Monday morning in parts of
Kalispell, US-2 and especially thru Bad Rock Canyon.

Farther to the south snowfall amounts will be much less (1 to 4
inches) as the more favorable forcing will not be present. However
this could change should the boundary between warm/moist and
arctic/dry air shift south. So please stay tuned for additional
updates.

Snowfall intensity will significantly decrease Monday night, but
not end. Persistent NW flow will keep moisture and a favorable
environment for snow showers in place thru Wednesday. The next
storm of significance is forecast to impact the Northern Rockies
on Thursday with more snowfall. However the absence of an arctic
boundary will focus the heaviest snowfall to be due to warm air
advection (warm front) followed by a more traditional cold front.
In fact, snow banding could come into play adding additional
enhancement to the snowfall potential. Thereafter cooler, showery
conditions seem to stay in the forecast leading into next weekend
with a possible drying trend by Sunday.

&&

.AVIATION...Snow will impact flight operations at KGPI for the
next several days. KMSO will see periods of mixed wintry
precipitation, transitioning back to snow overnight. KBTM will
largely be down sloped through this evening with occasional
showers developing Sunday morning. KSMN has recently begun
experiencing light freezing rain and will likely see occasional
mixed wintry precipitation overnight.
