What forecasters said that day

The local office's own words before this high wind 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 high wind warning went out at Oct 17, 11:50 AM MDT, 59 minutes earlier.

Area forecast discussion, Oct 17, 11:50 AM MDT, 59 minutes before
Area Forecast Discussion
National Weather Service Great Falls MT
1150 AM MDT Thu Oct 17 2024

.SYNOPSIS...

Temperatures today will be much cooler, with highs mostly in the
40s and 50s. Expect morning rain showers around Havre and
Lewistown, while rain and snow will occur throughout the day over
Kings Hill and across Southwest MT. The precipitation moves
eastward on Friday morning, with a mostly dry weekend, along with
a return to above normal temperatures.

&&

.Update...

Morning update has been published, with the main adjustment being
to update update hourly PoPs to incorporate latest short-term
guidance. Otherwise the remainder of the forecast remains on
track, with the expected brief lull in precipitation across
Southwest Montana now occurring ahead of the next push (of
precipitation) which will move in from late this morning and
persist through the late evening hours tonight or early morning
hours on Friday. Most of the focus of this next push of
precipitation will be along and south of the I-90 corridor, with
the heaviest precipitation falling in and near the Tobacco Root
Mountains, Gravelly, Gallatin, and Madison Ranges. Main concern
with this second push of precipitation given its timing to the
evening commute will be how much snow accumulates in the Madison
River Valley, Beaverhead and Western Madison valleys below
6000 feet, and Gallatin Valley as snow levels will be falling
through the day. Latest Hi-Res Ensemble Forecast (HREF) probabilistic
information gives a 40-70% chance for at least 1" of snow in the
Dillon, Ennis, and Bozeman areas through the evening hours
tonight, with a 30-40% chance of 2" in the Dillon and Bozeman
areas. Will consider a Winter Weather Advisory for these areas
through the remainder of the morning, but will hold-off for now
given the fact that despite falling snow levels road surface
temperatures will only be marginally cold enough to allow for
accumulating snow (i.e. most accumulations will likely only occur
on grassy surfaces). - Moldan

.AVIATION...
17/18Z TAF Period

After a lull in the mountain snow/valley rain across Southwestern
Montana, mountain snow and a mix of valley rain and snow will return
to portions of Southwestern Montana this afternoon and evening,
particularly around KEKS, KBZN, and KWYS. Expect a mix of MVFR to
IFR conditions at these airports as vis and cigs fluctuate with the
return of precipitation. Elsewhere, expect VFR conditions to prevail
with just some VFR cigs along and north of a line from KHLN to KGTF
to KLWT.  Ludwig

and hazard information.

.PREV DISCUSSION...
/ISSUED 602 AM MDT Thu Oct 17 2024/
Key Points
1. Much cooler today
2. Snow levels lowering throughout the day over Southwest MT
3. A period of heavier snowfall late this afternoon through this
   evening around Big Sky/Bozeman/Bozeman Pass
4. Turns windy over the weekend
5. Afternoon temperatures near 20 degrees above normal by Sunday
   over North Central MT

Today through Friday...The main Pacific cold front has pushed
through the CWA. Colder air is slowly moving down from aloft. Snow
levels are running around 7000 feet this morning, and continue to
slowly fall. The first wave of precipitation should end by late
morning. Then an upper level disturbance will move across
Southwest MT late this afternoon/evening. This will result in
another period of heavier precipitation. Snow levels will
continue to fall this evening. The snow could be briefly heavy in
the city of Bozeman around 5 PM, should the band of heavier
snowfall this afternoon develop over the city. Overall, no changes
to the current winter highlights, expect that the end time for
the advisory areas on Friday have been pushed up to 6 AM Friday
morning. Most of the snow on Friday morning will be confined to
mountain areas in zone 330, thus no change to that end time.
Current storm total snowfall amounts still look on track from
previous forecasts. Do expect cooler afternoon temperatures today
and Friday across the CWA.

Saturday through Sunday...A brisk westerly flow aloft will develop
over the CWA this weekend. This will allow for the potential for
strong winds to develop over the Northern Rockies by Saturday
morning. There is an 80 percent chance of some of the windier
locations having wind gusts over 75 mph on Saturday. Thus a high
wind watch has been issued for this area. Elsewhere, it will be
windy along with much above normal temperatures by Sunday.

Monday through Thursday...A fast moving upper level trof moves
over the CWA Monday into Tuesday, for a small chance of passing
showers and slight cooler temperatures. However, this disturbance
will be quick and short lived, as a small upper level ridge starts
to rebuild over MT by Wednesday. This will result in another few
days of dry conditions and above normal temperatures for Wed/Thu.
