Area Forecast Discussion
National Weather Service Great Falls MT
1145 AM MDT Thu Oct 3 2024

Aviation Section Updated

.UPDATE...

Except for a few mid-level clouds streaming east across central MT
beneath the right entrance region of an exiting upper level jet
maximum, skies are mainly clear across the region this morning.
Dry westerly flow aloft and surface high pressure shifting east
across the Canadian Prairies and MT today will bring quiet
weather conditions through this evening with seasonable
temperatures, relatively light winds and mainly clear skies.
Hoenisch

&&

.SYNOPSIS...

Upper level ridging will allow for benign conditions today across
the region, with temperature near average. Temperatures rise well
above average tomorrow before a Pacific cold front sweeps across
the area Friday night into Saturday, bringing another period of
stronger winds. Benign conditions return late weekend through much
of next week as upper level ridging builds back in.

&&

.AVIATION...
03/18Z TAF Period

VFR conditions expected with some high clouds rolling in from the
west this afternoon. Winds will generally stay light through late
tomorrow morning, where winds (out of the south/southwest) will
begin an increasing trend towards the end of the TAF period. -Wilson

Refer to weather.gov/zlc for more detailed regional aviation
weather and hazard information.

&&

.FIRE WEATHER...

Gusty southwest winds ahead of an approaching upper level
disturbance will result in increased fire weather concerns during
the day Friday in the corridor between Bozeman and Helena. The gusty
southwest winds will bring warm temperatures and low relative
humidity to the area, which combined with drying fuels (Driest
in the aforementioned area) will result in at least elevated fire
weather concerns through the afternoon and early evening Friday.
Additionally, a cold front will sweep across the region Friday
evening into Friday night, which will result in another period of
gusty winds. Although relative humidity will be on the increase
behind the front, the wind shift and associated strong gusts after
a day of dry and windy conditions will also raise concerns for
containment should any fire starts occur. -AM

&&

.PREV DISCUSSION...
/ISSUED 450 AM MDT Thu Oct 3 2024/

Through Saturday... Impactful weather will be confined to this
portion of the forecast, largely in the form of gusty winds Friday
into Saturday. In the meantime, ever so slightly cyclonic
northwesterly flow aloft will become increasingly anti-cyclonic
through the day today. A few showers remain across the eastern
plains early this morning, but will slide eastward and diminish as
upper level ridging builds in today. Overall today will be benign,
with light winds and a bit of upper level cloudiness by late day.
Temperatures will remain close to average today.

The period of greatest concern begins late Friday morning and early
afternoon, initially across Southwest Montana. A sharp upper level
trough will slide quickly eastward from the Pacific Northwest toward
the Northern Rockies during the day Friday. Southwesterly flow ahead
of this system increases during the morning Friday, which will help
push temperatures well above average across the entire region. As
daytime mixing ensues, the stronger winds aloft will begin to mix
down to the surface, mostly across Southwest Montana late morning
into the afternoon. The chance for a 55 mph gusts across Southwest
and portions of Central Montana continues to increase, hence a High
Wind Watch was issued for these areas, which goes through the
overnight Friday night for reasons to be discussed further below.
See the Fire Weather Section for details regarding fire weather
concerns from windy and dry conditions Friday.

The second round of strong wind gusts will arrive by way of a cold
front Friday evening into the overnight. The aforementioned upper
trough and developing cross barrier flow will result in a surface
trough across far southern AB which will kick off eastward
towards SK Friday evening. The result is for a cold front to sweep
across the region. Winds aloft just behind the front are rather
strong and although the front largely passes across the region at
night, these winds should still be able to mix to the surface for
at least a couple hours behind the front. Additionally, although
the winds will be downslope in nature, the overall strength of the
upper trough will still allow for at least an outside shot for a
shower with the front which may also help mix strong gusts to the
surface. The chance for a 55 mph gust has increased over the
plains and into Central Montana Friday evening and Friday night,
hence the High Wind Watch was expanded to cover remaining areas
across the region.

Winds slowly diminish through the day Saturday as the system quickly
exits eastward. Temperatures look to fall much closer to average,
though stay a touch above average across Southwest Montana.

Sunday into much of next week... Ensemble guidance is unanimous sin
building an upper level ridge in from the west Sunday. Benign
conditions will move back in for the region into much of next week,
with the only uncertainty in cluster analysis stemming from when the
ridging eventually slides east of the area late next week. The
chance for daytime highs at lower elevations to reach or exceed 70F
Monday through Wednesday next week is greater than 70%, and is much
closer to 90% in most areas. -AM
