What forecasters said that day

The local office's own words before this wind chill 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 wind chill warning went out at Mar 2, 1:44 PM MST, 8 minutes earlier.

Area forecast discussion, Mar 2, 1:44 PM MST, 8 minutes before
Area Forecast Discussion
National Weather Service Great Falls MT
144 PM MST Sat Mar 2 2019

.SYNOPSIS...

Cold temperatures and dangerously cold wind chills will impact the
region through the remainder of the weekend and potentially into
early next week.  High pressure settles in over the Northern part of
the state tonight, with some gusty winds increasing over parts of
north and central Montana. Otherwise, some drier conditions are
expected for much of the region over the next day or two.

&&

.DISCUSSION...

Tonight through Tuesday night...Cold temperatures will persist
over much of the region through the early part of next week,
along with drier conditions and some gusty winds causing
dangerously cold wind chills over parts of North and Central
Montana. There is potential for some valley locations to see
ambient temperatures as low as -40F tonight. Issued a Wind Chill
Advisory for parts of Central Montana through Sunday morning,
and a Wind Chill Warning for Blaine, Hill, and Ferguson Counties
for this evening through early Sunday afternoon. Coldest wind
chills will likely be during the overnight period tonight and
tomorrow night, especially when gusty winds increase tonight over
our eastern most counties. The temperatures and accompanying wind
chill values will likely increase during the day tomorrow,
depending on how much sunlight we receive. However, once the sun
sets and starts transitioning to night, the very cold temperatures
and wind chills are likely to return. Tuesday will see an upper
level ridge build across the area. Dry conditons are still
expected. We will however see a shift to a more west to southwest
flow. This will bring some warming, although still below normal
temperatures. -TP

Wednesday through Saturday...A shift to a slightly more active
pattern may then be found in the long term forecast. Two large
upper level lows across the Pacific NW will send waves of energy
and moisture over the region as early as Wednesday and continuing
through the end of the week. Chances for snow will be found for
most areas, although widespread and long periods of precipitation
does not look prevalent with these more progressive moving
disturbances. One concern will be the potential for freezing rain,
mainly across the southwest, for Wednesday into Thursday.
Confidence is low at this point and will be something to watch
over the coming days. With this Pac NW air mass warming
temperatures are also expected for mid to late week. With all the
snow on the ground it may still be tough to see normal
temperatures. Although some areas could see temperatures warm into
the 20s to perhaps low 30s. With cold temperatures at night and
warming during the day, the threat of ice jams will continue.

.AVIATION...
Updated 1030 AM MST Sat Mar 2 2019

Some lingering MVFR/IFR conditons under persistent snow showers
continue over parts of Southwest Montana, including KBZN and KHLN
terminals.  These conditions are expected to taper off quickly over
the next few hours to VFR conditions, as higher pressure builds into
the area from the north.  VFR conditions along with very cold
temperatures are expected to persist through the remainder of the
TAF period. Mountain obscuration is possible through this
afternoon. -TP

&&

.HYDROLOGY...

In the Ennis area, emergency management reports flood waters from
ice jams on the Madison River and O'Dell Creek are spilling over
portions of U.S. Highway 287. A flood warning has been issued for
this area until further notice.

A flood warning is also in effect for an ice jam on the Gallatin
River near Logan.

Ice jamming on the Missouri River south of the City of Cascade has
caused minor flooding to develop across portions of Southwest
Cascade County. This minor flooding has led to the closure of Sheep
Creek Road. With continued cold temperatures in the forecast, a
flood advisory is in effect for the this region until further notice.
