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 Feb 28, 8:43 PM MST, 3 hours 31 minutes earlier.

Area forecast discussion, Feb 28, 8:43 PM MST, 3 hours 31 minutes before
Area Forecast Discussion
National Weather Service Great Falls MT
843 PM MST Tue Feb 28 2023

.SYNOPSIS...

Snow and snow showers will persist through the evening and early
morning hours on Wednesday across the Northern Rockies, with the
most persistent light snow expected across northeastern portions
North Central Montana. South and west winds will begin to increase
across Southwest through North Central Montana on Wednesday,
becoming particularly strong along the Rocky Mountain Front
Wednesday night and through the day on Thursday.

&&

.UPDATE...
/843 PM MST Tue Feb 28 2023/

The NWS Great Falls forecast area includes north central, central
and southwest Montana.

The Winter Weather Advisory for Hill and Blaine Counties and The
Bears Paw Mountains is cancelled. Some areas of lingering light
snowfall are expected.

Updates to the forecast include, adjusting wind speed values down,
a bit, for north central and central Montana, and up, a bit, for
the southwest portion of the state. Additionally, with moisture
ending earlier than originally forecast, have reduced Probability
of Precipitation (POP) values across some areas. Areas of fog are
forecast; however, with broken to overcast skies forecast to
continue throughout the night, dense fog is not forecast. Area of
greatest concern will be the Milk River Valley. Will pass this
onto the oncoming midnight shift.
- Fogleman

&&

.UPDATE...
/553 PM MST Tue Feb 28 2023/

The Winter Weather Advisory for the East Glacier Park, Kiowa,
Marias Pass, Logan Pass, Saint Mary and Babb, has been allowed to
expire. Some lingering light snow is expected, in that area.
- Fogleman

.AVIATION...
520 PM MST Tue Feb 28 2023 (01/00Z TAF Period)

The NWS Great Falls Airfields include: KCTB, KHVR, KGTF, KLWT, KHLN,
KBZN and KEKS.

KCTB begins this TAF period in IFR conditions due to low ceiling.
From 01/03Z conditions at KCTB improve into the MVFR range.
Conditions at KBZN are forecast to remain VFR throughout this
period. MVFR conditions are forecast to occur during this TAF period
at all other airfields due to low ceiling. PROB30s are included in
the KEKS TAF adding the probability of IFR conditions in light snow
and mist and with low ceiling. Conditions at all airfields improve
with time. Mountain obscuration is forecast. KLWT to KHLN, along
with our southwest Montana airfields, include gusty winds up to 26KT
at the onset of this TAF period. Winds gradually decrease, and by
01/06Z, generally light winds are forecast at all airfields.

.PREV DISCUSSION...
/ISSUED 520 PM MST Tue Feb 28 2023/

Rest of today through tonight...primary concern will be light
accumulating snow across northeastern portions of North Central
Montana, in addition to convective snow showers capable of producing
gusty and erratic winds and even an occasional lightning
strike/flash across Central Montana. Open H500 shortwave sliding east
from over the Northern and Central Rockies to the Northern High
Plains through this evening will continue to promote scattered snow
showers across portions of Southwest through North Central Montana.
These snow showers have been the most "intense" between the Montana
Hwy 200 and US Hwy 12 corridor across Central Montana where earlier
clearing has led to steep lapse rates amongst semi-unstable LI's.
Expect coverage of the snow showers to decrease through the early
evening hours tonight with the loss of solar insolation, with the
primary area of snow residing across northeast portions of North
Central Montana where low level frontogenesis will promote a more
stratiform type of precipitation. This light stratiform snow is
expected to lead to 1-3" of snow through early Wednesday morning
across Hill, North Blaine, and the Bears Paw Mountains; thus the
Winter Weather Advisory will remain in effect until 12z Wednesday
here.

Wednesday through Thursday...primary concern throughout the period
will be increasing south to west winds, most notably along the Rocky
Mountain Front and the plains east to the I-15 corridor across
Central and North Central Montana. Strengthening pressure gradient
due to a sharpening lee-side surface trough will lead to increasing
winds during the afternoon and evening hours on Wednesday across the
CWA, with the pressure gradient expected to peak along the Rocky
Mountain Front (17-22mb/km), Montana Hwy 200 corridor (7-12mb/km),
and south of the I-90 corridor in Southwest Montana (5-10mb/km)
between 09-18z Thursday. This peak in the pressure gradient is when
wind speeds/gusts are also expected to peak. While the pressure
gradient alone will lead to widespread sustained wind speeds of 15-
30kts across the aforementioned regions, further enhancement to
surface winds are expected along the Rocky Mountain Front due to
increasing cross barrier flow to 40-60kts and the mountain wave
activity. NBM probabilistic data suggest an 85% chance that wind
gusts will exceed 48kts and a 50% chance of exceeding 56kts at Cut
Bank. Further west there exists a 100% chance of exceeding 48kts,
90% chance of exceeding 56kts, and 55% chance of exceeding 64kts at
Browning. Additionally, both Browning and Cut Bank have between a 90-
100% chance of seeing sustained wind speeds of 34kts or higher. This
high probabilistic support combined with the aforementioned support
for mountain wave activity has increased confidence to the point
where a High Wind Watch has been issued for the Eastern Glacier Park
Region, Southern Rocky Mountain Front, and Northern and Southern
High Plains from 21z Wednesday through 01z Friday, and Eastern
Glacier, Western Toole, and Central Pondera Counties from 07z
Thursday through 01z Friday. In addition to the strong winds across
the High Wind Watch area, blowing and drifting snow will also be of
concern, which could lead to additional travel impacts. - Moldan

Friday through next Tuesday...Below normal temperatures continue
for Friday and Saturday, but it will be a bit warmer than earlier
in the week. The weather pattern will start to change to a cold
and snowy weather pattern once again from Sunday through Tuesday,
as a deep upper level trof tries to develop over the western U.S.
Much below temperatures are expected by early next week, along
with periods of snow. Brusda
