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 Dec 7, 10:37 PM MST, 4 hours 51 minutes earlier. Its key messages:

  • It will be windy tonight along the Rocky Mountain Front and Monday afternoon/evening through Tuesday it will be windy across North-central, Central, and Southwestern Montana.
  • There will be daily rounds of snowfall in the mountains during this work week with snowfall returning to the lower-elevations to end the work week.
  • It will be warm through the middle of the work week with cold temperatures to end the work week.

Aviation Section Updated.

.KEY MESSAGES...

 - It will be windy tonight along the Rocky Mountain Front and
   Monday afternoon/evening through Tuesday it will be windy
   across North-central, Central, and Southwestern Montana.

 - There will be daily rounds of snowfall in the mountains during
   this work week with snowfall returning to the lower-elevations
   to end the work week.

 - It will be warm through the middle of the work week with cold
   temperatures to end the work week.

&&

.UPDATE...
/Issued 751 PM MST Sun Dec 7 2025/

A weak wave traversing northwesterly flow aloft has combined with
sufficient moisture to result in a brief period of lower
elevation rain and mountain snow this evening. Snow accumulation
has generally been less than an inch at pass level, though
isolated locations have seen a bit more. The precipitation moves
off to the east later tonight, transitioning the greatest concern
to wind, mostly over the plains through the night.

Winds at 700 mb increase through the remainder of the evening into
the overnight, exceeding 50 kts along the Rocky Mountain Front.
Although a building pressure gradient and weak ridgetop stability
will help translate a few stronger gusts to the surface, the
orientation of winds aloft (More northwesterly) do not align with
the surface winds (More westerly to southwesterly). This results
in a lesser confidence in any widespread gusts in excess of 65 mph
along the Rocky Mountain Front through the night. Hence, no High
Wind Warnings are being considered at this time for the overnight
into early Monday.

Only minor tweaks were made to the near-term portion of the
forecast to account for latest trends and guidance. -AM

&&

.DISCUSSION...
/Issued 751 PM MST Sun Dec 7 2025/

 - Meteorological Overview:

This afternoon there is an upper-lever ridge over North-central,
Central, and Southwestern Montana. This will allow temperatures to
be warm with mostly dry weather. However Hill and Northern Blaine
Counties will be slow to warm up. This afternoon through tonight
there will be light precipitation primarily confined to the
Continental Divide. This evening through tomorrow morning due to
strong low and mid-level winds and a strong pressure gradient it
will get windy across North-central Montana with the strongest winds
along the Rocky Mountain Front. The upper-level ridge will remain
over North-central, Central, and Southwestern Montana on Monday
which will allow temperatures to warm up some more with dry weather
at lower-elevations and mountain snow. Due to an increasing pressure
gradient combined with strong low and mid-level winds, winds will
begin to increase Monday afternoon and evening. On Tuesday the upper-
level ridge flattens before another upper-level ridge builds in
Tuesday afternoon. This will bring precipitation chances to the
mountains of North-central, Central, and Southwestern Montana
Tuesday. Due to a strong pressure gradient combined with strong low
and mid-level winds it will be windy across North-central,
Central, and Southwestern Montana on Tuesday.

On Wednesday the upper-level ridge remains over North-central,
Central, and Southwestern Montana this will allow the warm
temperatures to continue. Wednesday evening an upper-level shortwave
associated with an Arctic Cold Front will move through and bring
precipitation chances to the area with windy conditions. On Thursday
there is northwest flow aloft over North-central, Central, and
Southwestern Montana. This combined with the Arctic Cold Front will
bring cooler temperatures, precipitation chances, and windy
conditions to the area on Thursday. The coldest temperatures will be
in North-central Montana particularly along the Hi-Line. On Friday
northwest flow aloft remains over North-central, Central, and
Southwestern Montana. This will keep the cool/cold temperatures over
the area with precipitation chances. On Saturday an upper-level
ridge will build in over North-central, Central, and Southwestern
Montana. This will allow temperatures to slowly warm back up with
mostly dry weather. -IG

 - Forecast Confidence & Scenarios:

Tonight through Monday morning there is greater than a 60% chance
for wind gusts of 75 mph or greater along the Rocky Mountain
Front. Due to this probability being a little on the low side for
a warning plus low confidence in a mountain wave to bring the wind
gusts down, a High Wind Warning was not issued for this area from
tonight through Monday morning but there is a high likelihood of
wind gusts in excess of 60 mph along the Rocky Mountain Front
tonight through Monday morning.

On Monday there is greater than a 70% chance for wind gusts of 55
mph or greater along the plains west of I-15. On Monday and Tuesday
along the Rocky Mountain Front there is greater than a 80% chance
for wind gusts of 75 mph or greater. On Tuesday there is greater
than a 50% chance for wind gusts of 55 mph or greater across most of
North-central, Central, and Southwestern Montana. There is greater
than a 70% chance for sustained winds of 40 mph or greater along the
plains west of I-15, in the Madison River Valley, and in the Geyser
vicinity. High wind watches remain in effect for North-central and
Central Montana and the Madison River Valley for Monday
afternoon/evening through Tuesday morning.

On Monday there is a 20 - 40% chance for high temperatures of 45
degrees or greater across most of the lower-elevations of North-
central, Central, and Southwestern Montana. On Tuesday and Wednesday
there is greater than a 50% chance for high temperatures of 45
degrees or greater across most of the lower-elevations of North-
central, Central, and Southwestern Montana. From now through Monday
morning there is greater than a 75% chance for 2 inches of snow or
greater along the Rocky Mountain Front. From Monday morning to
Tuesday morning there is greater than a 60% chance for 4 inches of
snow or greater along much of the Rocky Mountain Front. From Tuesday
morning through Wednesday morning there is greater than a 50% chance
for 4 inches of snowfall or greater along the Continental Divide. -IG

&&

.AVIATION...
08/06Z TAF Period

The primary concern this TAF period will be for increasing surface
winds and gusts, initially across the plains through the remainder
of the night. In areas where surface winds are slow to increase,
LLWS will be a concern into Monday morning. Mountain wave turbulence
will become increasingly common through the TAF period.

Another round of precipitation develops along the Continental Divide
Monday morning into the afternoon, which will obscure mountains. -AM
