Area forecast discussion, Feb 23, 10:55 PM MST, 4 hours 17 minutes before
Area Forecast Discussion
National Weather Service Great Falls MT
1055 PM MST Thu Feb 23 2023

Aviation Section Updated

.UPDATE...
Made some minor updates to the overnight period into Friday morning.
The more significant adjustment was to lower low temperatures on the
Rocky Mountain Front. Temperatures there had already fallen into the
20 to 30 below zero F range, so mostly lowered low temperatures
there about up to 10 degrees over the original forecast into the 30
to 35 below zero range. Mid level cloudiness is already starting to
move into that area with an approaching disturbance, so that should
help prevent most areas from falling to around or below 40 below
zero.

Speaking of the disturbance, the other adjustment was to make the
chance for light snow or flurries cover most of Southwest and
North Central Montana. Am not expecting much as far as additional
accumulation (mainly a trace at lower elevations and up to one
inch in the mountains), but there is a good chance that at least
flurries will occur across much of the area.

The Wind Chill Warnings and Advisories continue to handle the
situation well, so no adjustments there.

.SYNOPSIS...
Dangerously cold conditions will persist into Friday and Saturday
before ending, generally from southwest to northeast across the
region. Westerly winds increase Friday into Saturday with blowing
and drifting snow expected for some areas until temperatures rise
above freezing. The most significant impacts will be along the Rocky
Mountain Front and the adjacent plains. More passing disturbances
bring more gusty winds and mostly mountain snow Sunday into early
next week as temperatures trend closer to average.

&&

.AVIATION...
1055 PM MST Thu Feb 23 2023 (24/06Z TAF Period)

An area of light snow will move from south to north through the CWA
overnight. Some low ceilings will accompany the light snow. Patchy
fog is also possible before mid day Friday. Blowing snow could start
to have impacts by mid day Friday over the western half of the CWA.
Mountains/passes could be obscured at times over the CWA. Brusda

weather and hazard information.

.PREV DISCUSSION...
/ISSUED 625 PM MST Thu Feb 23 2023/

Rest of this Afternoon through Saturday Night...

We reissued Wind Chill Warnings for all of north-central Montana
and parts of southwest Montana given colder forecast low
temperatures more within the NBM probabilistic range, which is
considerably colder for some areas than the NBM deterministic
values. We also upgraded the Winter Storm Watch to a Winter Storm
Warning for significant blowing and drifting snow concerns for
the Rocky Mountain Front beginning late Friday morning and
lasting into Saturday. We did contemplate issuing a Blizzard
Warning for ground blizzard conditions but we are not quite
confident in how severe visibility will be. However, we do expect
significant infrastructure issues with severe drifting of snow
across roads.

West winds will begin along the Rocky Mountain Front as early as
the late morning hours Friday as a disturbance passes and a
cross- barrier gradient flow increases. The isallobaric pressure
rises may cause a sudden deterioration of intense blowing and
drifting snow along the immediate Rocky Mountain Front, with
winds gradually expanding out across the adjacent plains through
the afternoon and evening hours. NBM probabilistic guidance
indicates a greater than 80 percent chance of wind gusts
exceeding 55 mph for these areas by Friday night into Saturday.

The difficult aspect of issuing hazards in these types of events
is trying to determine when snow stops becoming transportable. In
this case, temperatures should rise to near or above freezing by
late Saturday afternoon across much of this area, which should
allow for an improvement in blowing and drifting snow. However,
gusty winds will continue into Saturday night.

Winter Weather Advisories for blowing and drifting snow are
likely to be needed along the eastern slopes of the remainder of
the central Montana mountains for Friday night into Saturday. In
these locations, wind gusts are more likely to be in the 40 to 50
mph range.

Temperatures will moderate significantly across the region Friday
through Saturday, reaching well above zero by Saturday night
everywhere except for perhaps the more sheltered portions of the
Milk River Valley in Hill and Blaine Counties.

Sunday through next Thursday...

Breezy conditions will continue into the day on Sunday as
moderate upper level flow continues over the region. That said,
blowing snow will not be as big of a concern on Sunday thanks to
a combination of above freezing temperatures, weaker winds, and
snow already being drifted. That said, there may still be some
blowing snow across the plains later in the afternoon as winds
pick up across the plains, but the warmer temperatures during the
day should put a damper on this.

As we head through the first half of the week, a series of minor
weather systems will roll through the Pacific Northwest, which
will bring some opportunities for some light mountain snowfall
across Southwestern Montana, as well as colder temperatures and
some elevated winds across the plains. Impacts from these systems
should be localized to mountain passes and higher elevation
communities, though some minor impacts could occur across the
plains Tuesday night/Wednesday morning as some snow attempts to
sneak into the area. A weak upper level ridge will move across
the area around midweek, which will bring briefly quieter and
warmer weather to the region for midweek. Ludwig
