.DISCUSSION...

Today through Wednesday night...

An active weather pattern is expected for the short term forecast.
The front is expected to move east through the morning hours,
which will shift wind to the northwest and allow cold air to be
filtered in. The lower elevations could see rain initially
before switching to snow as the temperatures drop. The heaviest
snow has shifted north of Musselshell county but a few models are
hanging onto a heavy band of snow from Yellowstone through Rosebud
Counties. The forecast may need to be adjusted this afternoon as
the snow moves into the area to account for heavier banding. At
this time, the plains will see 1 to 2 inches of snow through
tonight. A Winter Weather Advisory has been issued for the
Paradise Valley and Beartooth Foothills as those areas are
expected to see 3 to 4 inches with the Tuesday night system due to
a southwest flow. A Winter Weather Advisory was also issued for
Judith Gap as that zone will likely see 3 to 4 inches of snow
combined with gusty winds up to 35 mph tonight.

As we move into Wednesday, expect the area to dry out during the
day before another chance of snow moves into the area Wednesday
night. Recent model trends have shifted the location of the low
southeast from what have been seeing the last couple days which
shifts the heaviest snow into South Dakota. Areas south of a line
from Big Timber to Billings to Ekalaka will see 2 to 3 inches of
snow with localized heavier amounts. Areas north will see less
than 2 inches. The only highlights out for this system are the
continuation of the Winter Weather Advisory along the Paradise
Valley and the Winter Storm Warning for the Beartooth Mountains.
This may need to be adjusted as we move into Wednesday.

High temperatures today will be ahead of the front with cooling
expected behind. High temps will be in the low 40s near
Livingston, warming to the upper 50s along the ND/SD border.
Wednesdays highs will struggle to reach the 30s. Expect low temps
to drop into the teens and 20s tonight with single digits and
teens expected Wednesday night.

Carrothers

Thursday through Monday...

Snow will be ongoing Thursday morning across southern and eastern
zones, decreasing through the afternoon as the system shifts east
of the area. Expect an inch or two of accumulation along and south
of a Fort Smith to Ekalaka line. Area remains under the influence
of a broad trof across the western U.S. through the weekend. This
will keep temperatures below normal along with a chance for
precipitation in the forecast. Chambers

.AVIATION...

An area of scattered rain/snow showers will move across the
forecast area this morning with associated MVFR/IFR conditions.
Mountains will see snow showers and obscurations. A better chance
for precipitation (rain/snow->snow) develops late this afternoon
along and mainly west of a Red Lodge to Billings to Miles City
line, and continues into tonight. IFR conditions will become
predominant with precipitation areas late this afternoon into
tonight. BT
