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 Great Falls, MT wrote its last area forecast discussion before this winter storm warning went out at Feb 5, 3:46 AM MST, 1 minute earlier.

Area forecast discussion, Feb 5, 3:46 AM MST, 1 minute before
Area Forecast Discussion
National Weather Service Great Falls MT
346 AM MST Wed Feb 5 2020

.SYNOPSIS...

Snow will redevelop over the southern and western Montana today,
and spreading into parts of central montana by this afternoon.
Expect the snow to continue over these regions Thursday into
Friday morning. A second storm system will affect the region this
weekend, with another round of snow and colder temperatures.

&&

.DISCUSSION...
A fairly strong upper level disturbance moves southward into the
region today, along with moist northwesterly flow, bringing
widespread snow to parts of Southwest and Central Montana today
through friday morning. The heaviest snow amounts will occur over
the southwest Mountains, causing difficult travel into winter
recreation areas and increasing avalanche potential. There is
slightly better confidence overall, however, there remains some
uncertainty in storm total snow accumulations in the Southwest
valleys, particularly with regard to snow levels and valley
temperatures. The Winter Storm Watches have been upgraded to a
Winter Storm Warning for Gallatin County, and Winter Weather
Advisories for the remaining southwest and central counties. -TP

Saturday through Tuesday...A second storm system is progged to
move through the region on Saturday and exit the area on Sunday.
Snow amounts of several inches look possible with this system.
Additionally, some convective snowfall is possible with the second
system, resulting in some high snowfall rates. Winter weather
highlights will likely be needed for portions of the region for
this event as well. Monday looks to be mostly dry, with increasing
chances for snow again by next Tuesday. Overall NBM guidance
looked a bit on the warm side, so afternoon temperatures were
adjusted down a few degrees from Sunday through Tuesday.

&&

.AVIATION...
Updated 1055 PM MST Tue Feb 4 2020 (05/06Z TAF Period)

A disturbance moving southeast through central and southwest Montana
(including terminals from KGTF and KLWT south) will continue the
MVFR/IFR conditions in light to moderate snow showers with mountain
obscuration; conditions there will gradually improve to VFR from the
north with partially clearing skies through 13Z. The Hi-Line
(including KCTB and KHVR) will remain VFR with mostly clear skies.
However, westerly winds along the Rocky Mountain Front will continue
to be strong with gusts exceeding 35 kt through at least 12Z.
Increasing Pacific moisture in the northwest flow aloft will bring
increasing clouds with mountain-obscuring snow once again after 18Z,
as well as MVFR/IFR conditions in the southwest valleys.  Coulston
