What forecasters said that day

The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Missoula, MT wrote its last area forecast discussion before this winter storm warning went out at Feb 11, 4:12 AM MST, 6 hours 56 minutes earlier.

Area forecast discussion, Feb 11, 4:12 AM MST, 6 hours 56 minutes before
Area Forecast Discussion
National Weather Service Missoula MT
412 AM MST Mon Feb 11 2019

...PROLONGED SNOW WITH PERIODS OF MODERATE SNOW THROUGH THE MIDDLE
OF THE WEEK...

.DISCUSSION...

A surge of Pacific moisture over the Northern Rockies today will
quickly moderate temperatures well above zero, as well as produce
widespread light snowfall. Most locations will experience a quick
few inches of snow, further exacerbating hazardous winter driving
conditions throughout the region.

A period of overrunning (warm, moist air riding over the top of
cold air at the surface) will produce moderate to heavy snow
tonight into Wednesday. While snow will initially impact most all
of central Idaho and western Montana tonight, forecast models show
the main surge of moisture will focus through the Idaho panhandle
into northwest Montana during the day Tuesday. Hefty snow amounts
of 6 to 9 inches will be possible in these areas, with over a
foot of snow in the higher terrain near the Idaho/Montana border.
Locations from Missoula south and east will see much lower
snowfall, generally in the 1 to 3 inch range. In addition, a
southerly pressure gradient will set up tonight into Tuesday,
bringing some increasing wind through the Camas Prairie in Idaho
and southwest Montana. The wind coupled with snowfall could make
for a period of lowered visibility due to blowing snow, mainly
tonight into early Tuesday morning, before the focus of
precipitation shifts further north. Travel could become difficult
during this timeframe, especially near the Idaho/Montana border,
including over Lookout and Lolo Passes.

As a low pressure system dives southward along the Pacific
northwest coastline on Wednesday, the moisture focus will begin to
trend further south with time. This low will also help pull cold
Canadian air back along the Continental Divide. This colder air could
provide a focus for another period of moderate to heavy snowfall
for the Wednesday into Thursday morning time frame. Forecast
models continue to struggle a bit with the details around this
system, thus confidence is somewhat diminished. However, the
overall trend over the last few models runs is towards another
period of potentially significant snowfall, this time focused
generally along and south of the Highway 12 corridor.

Beyond Thursday, forecast models show little change in the
overall pattern, with continued surges of moisture capable of
producing widespread snow into the weekend, and possibly even into
early next week!

&&

.AVIATION...

A surge of Pacific moisture will move over the Northern Rockies
today, bringing widespread light snow and obscuring much of the
high terrain. All area terminals, including KBTM, KGPI, KMSO, and
KSMN, will experience high variability in ceilings and visibility
due to snowfall. Much of the snow activity will shift northward
after 12/1200Z and continue to impact primarily KGPI and KMSO with
lowered visibility and ceilings at times.
