.DISCUSSION...

 - Meteorological Overview:

Snowfall across Central and Southwestern Montana will come to an
end early this morning as the upper level trough that moved
through the area yesterday weakens and moves eastward. After a
mostly dry rest of the day across the area, our next round of
snowfall will push into the area overnight tonight as a cold front
begins to move in from the north. As this front pushes through
the area, most of the snow (and lower elevation rain) will be
focused mainly along the immediate Rocky Mountain Front though a
few heavier snow showers could form on the plains. Behind this
front, high pressure will build in at the surface followed by
ridging aloft for the weekend, which will result in a warmer and
drier weekend. Our next weather system will move into the area
early next week, bringing increased chances for rain and windy
conditions to the area.

 - Forecast Confidence & Scenarios:

Snow Tonight and Thursday: Light snow is expected to develop
along the Rocky Mountain Front and Plains overnight tonight and
tomorrow as a cold front pushes into the area from Canada. For the
most part, expect snow to be light and accumulations to be
minimal (and generally limited to grassy and elevated surfaces at
that), though a few opportunities do exist for some more impactful
snowfall. The main area will be along the Rocky Mountain Front,
where some easterly winds will result in upsloping, which will
yield a 40% or higher chance of 6 inches of snow in the higher
terrain (with an 80% chance in Glacier National Park). The other
opportunity for snow to be a bit more impactful will be if
convective snow showers are able to develop along and ahead of the
cold front, as these would result in brief periods of reduced
visibility and may be able to overcome melting on the roads and
result in briefly slick travel.

Early next week: As a cold front pushes into the area next week,
expect precipitation to be mainly rain across the lower elevations
with some snow over the passes. As colder air moves back into the
area, some gusty winds may be possible, particularly in the wind
prone areas near the Rocky Mountain Front. Ludwig

.AVIATION...
02/06Z TAF Period

The widespread snowfall over Central Montana associated with a
weak low pressure area will continue to shift more so into
Southwest Montana through 09Z, bringing widespread mountain
obscuring MVFR/IFR conditions through around 17Z. However, areas
of low clouds and fog are forecast to continue in the KLWT area
and develop across the remainder of the plains of Central and
North Central Montana through 11Z and persist until around 16Z,
causing terrain/mountain obscuring MVFR/IFR/LIFR conditions. Most
areas will improve to low VFR/MVFR ceilings after 16Z, but weak
instability may bring scattered rain and snow showers to much of
the area between 19Z and 01Z. After 00Z, more widespread MVFR/IFR
ceilings, possibly with some light snow, are forecast to spread
southeast out of Canada over the plains.
