816 FNUS55 KTFX 010708 FWFTFX Fire Weather Planning Forecast for North-Central Montana National Weather Service Great Falls MT 108 AM MDT Sat Aug 1 2026 ...RED FLAG WARNING IN EFFECT FROM NOON TODAY TO 9 PM MDT SUNDAY... .DISCUSSION... Critical fire weather conditions are forecast this weekend across all fire weather districts. Gusty winds developing this afternoon ahead of a dry cold front will combine with relative humidities approaching single digits to result in critical fire weather conditions in most areas. Winds shift to a more northwesterly direction this afternoon and evening behind the cold front. While gusty winds diminish somewhat out over the plains tonight, strong winds will develop along the Rocky Mountain Front this evening, slowly expanding over the plains through the night and into the day Sunday. Overnight humidity recovery is forecast to be nearly non-existent where these winds are persistent overnight near the Rocky Mountain Front. Although cooler temperatures will be moving in behind the cold front for Sunday, very low relative humidity will persist (Approaching single digits once again). Combine this with forecast breezy winds, and critical fire weather conditions will be around once again for Sunday. Winds diminish Sunday evening, leading to a less active beginning to the week from a fire weather perspective. After a briefly cool stretch Monday and Tuesday, temperatures trend warmer once again mid- week, with minimum relative humidity dropping into the teens once again. -AM MTZ112-012215- Eastern Glacier/Toole/Central/Eastern Pondera/Liberty- 108 AM MDT Sat Aug 1 2026 ...RED FLAG WARNING IN EFFECT FROM NOON TODAY TO 9 PM MDT SUNDAY... .TODAY... * Sky/Weather...........Mostly sunny.

.KEY MESSAGES...
- After a hot day today, temperatures trend cooler into Sunday
behind a cold front.
- Critical fire weather conditions develop this afternoon,
persisting into Sunday.
- After a briefly cooler stretch behind the cold front,
temperatures trend back warmer mid-week.
&&
.DISCUSSION...
- Meteorological Overview:
Strong upper level ridging in place across the region will quickly
be ushered eastward through the day today as an upper level trough
slides east near the International Border. Ahead of the approaching
trough temperatures rise well into the 90s across the region,
reaching as high as 110F or so in typically heat prone areas. The
ongoing Extreme Heat Warnings and Heat Advisories are unchanged
with this update. Those with plans outside today should plan for
numerous breaks and for plenty of hydration.
A dry cold front arrives as the upper level troughing moves eastward
this afternoon. Ahead of the front, breezy southwesterly winds
look to develop in many areas, transitioning to a more
northwesterly direction behind the front late afternoon and into
the evening. The strongest cross barrier flow aloft holds off til
this evening and tonight, peaking in excess of 60 kts along the
Northern Rocky Mountain Front. The combination of cooling
temperatures near the surface behind the front and still mild
temperatures aloft will result in some ridgetop stability tonight
along the Rocky Mountain Front. This will aid in translating the
aforementioned stronger winds aloft to the surface in these areas
via mountain wave activity. The strongest winds aloft fade quickly
after sunrise Sunday, though the continued brisk westerly flow
aloft will keep gusty winds around through the day Sunday.
A quick moving trough in wake of the initial troughing that will be
exiting eastward by Sunday afternoon moves across the area Sunday
night. This trough looks to have enough moisture associated with
it to result in a brief stretch of light precipitation along the
Northern Rocky Mountain Front Sunday evening and overnight.
Temperatures aloft look to be quite cool, which will yield the
risk for some light snow near mountain peaks in Glacier NP over
this timeframe.
A cooler northwesterly flow aloft persists into the early week across
the region, resulting in a below average temperatures across the
region for a couple days. This trend looks to be short-lived however,
as temperatures begin to trend warmer by mid-week. -AM
- Forecast Confidence & Scenarios:
Strong winds tonight:
Ridgetop stability will yield a good setup for translating stronger
winds to the surface tonight near the Rocky Mountain Front. Given
the strongest winds aloft continue to take aim at the Northern Rocky
Mountain Front, and largely only nick the Southern Rocky Mountain
Front, no changes are being made to the ongoing High Wind Warning.
Should the stronger winds aloft trend much further southward,
additional High Wind Warnings may become necessary near the Southern
Rocky Mountain Front. -AM
&&
.AVIATION...
01/06Z TAF Period
VFR conditions will prevail across all terminals during this TAF
Period. However, smoke from wildfires has been periodically reducing
visibility at the KCTB and KHVR terminals this evening and will
continue to do so through at least 01/10Z. Across all terminals
after 01/18Z winds will begin to increase with the strongest winds
being at the KCTB terminal. At the KCTB terminal by the end of this
TAF Period winds will gust in excess of 40 kt. Across most of the
TAF sites smoke from wildfires will reduce slantwise visibility
during this TAF Period. At the KCTB terminal there will be
isolated instances of low-level wind shear at the very end of
this TAF Period. -IG
For KGTF: Winds will be light through 18Z. Between 18Z and 23Z
winds will increase and shift from the southwest to the west.
Between 21Z and 00Z there is a 70% chance for a 15 kt crosswind.
-IG
&&
.FIRE WEATHER...
Critical fire weather conditions are forecast this weekend across
all fire weather districts.
Gusty winds developing this afternoon ahead of a dry cold front will
combine with relative humidities approaching single digits to result
in critical fire weather conditions in most areas. Winds shift to a
more northwesterly direction this afternoon and evening behind the
cold front. While gusty winds diminish somewhat out over the plains
tonight, strong winds will develop along the Rocky Mountain Front
this evening, slowly expanding over the plains through the night and
into the day Sunday. Overnight humidity recovery is forecast to be
nearly non-existent where these winds are persistent overnight near
the Rocky Mountain Front.
Although cooler temperatures will be moving in behind the cold front
for Sunday, very low relative humidity will persist (Approaching
single digits once again). Combine this with forecast breezy
winds, and critical fire weather conditions will be around once
again for Sunday. -AM
