.DISCUSSION...

Temperatures had warmed into the 40s and 50s over the area today
with downslope flow in place and ridging overhead. Ridge axis will
slide east tonight with a weak wave moving into the region
increasing snow chances over the western mountains. A few inches
of snow are possible over the western mountains. As the shortwave
slides east through the area overnight, a few isolated showers
are possible. While they look to be mainly a mix of rain and snow,
there is a very small chance that there could be some freezing
rain over northeastern areas if a shallow layer of colder air near
the surface develops. Will continue to monitor the potential.

Low pressure system over northeast Montana slides east into North
Dakota on Saturday with mainly dry conditions for most places,
outside of continued snow chances over the southwest mountains.
Breezy west to northwest winds can be expected over the area on
Saturday. High temperatures on Saturday will range from the 40s
to lower 50s. Low temperatures tonight and Saturday night will
range from the 20s to lower 30s. STP

Sunday through Friday...

Unseasonably warm temperatures will persist through next week,
with periods of light rain and snow throughout, and a windy end to
the week.

Gap winds near Livingston will continue to decrease through
Sunday as a shortwave moves through western Montana. As the
shortwave reaches eastern Montana later in the day, a round of
light rain and snow, coinciding with the brief shift to
northwesterly low-level winds, will occur Sunday night into
Monday morning. No major accumulations expected. Beginning with
this shortwave and persisting periodically through the week will
be mountain snow, with southern and western facing slopes
containing the best potential for moderate accumulations.

GEFS and the GFS are indicating a weak clipper-like shortwave
passing through on Wednesday and bringing another round of light
precipitation. Although confidence is low on the possibility of
precip (and a slight dip in temperatures), little to no
accumulations would be expected.

Confidence is slowly increasing for a gap wind event occurring by
Friday in the Livingston-Big Timber vicinities and persisting
through the weekend, with a brief shot of high winds across much
of SE Montana on Friday as well. However, more specific details
are still unknown at this time.

Temperature will remain mild, with highs in the 40s to low 50s
most of next week. A dip in temperatures is still indicated for
the following week in early February, so for all of you cold
weather enthusiasts out there, don`t give up just yet.

.AVIATION...

Mountains will be obscured at times in snow showers through the
period. Otherwise, VFR conditions will prevail across the lower
elevations with passing mid and high clouds. Some isolated showers
may spread east across the area overnight as a weak disturbance
moves through the region. Breezy SW to W surface winds will
continue along the western foothills. STP
