.DISCUSSION...
Rest of Today through Wednesday Night...

Benign weather continues with east winds keeping temperatures
around a modest upper 40s to low 50s will persist through the
afternoon. Upslope flow and weak mid-level moisture will still
allow a very small chance for snow showers to occur in the
foothills west of Billings this afternoon, but for now it
continues to occur as virga.

Tonight, a cold front will swing across eastern Montana, bringing
with it a few inches of snow to the mountains, especially on south
to west facing slopes, and a small chance for light snow across
south- central Montana. For the lower elevations, no major
accumulations are expected, amounts will generally be under an
inch if snow even occurs in the first place. Despite the cold
front passing through, low will stay similar to last night and
only get down to the upper 20s. Northwest to downslope flow
persists throughout Tuesday as a surface low moves east across
the Dakotas. Good mixing looks to occur to mix down winds that
look to gust 30-35 mph across much of southeast Montana, and light
snow will continue to occur in the mountains.

Tuesday night through Wednesday, a shortwave moving through Wyoming
will bring more snow to the mountains, especially the Bighorns.
The bighorns look to get 3-6 inches throughout the day, with maybe
a couple inches in the foothills in far southern Sheridan County.
Most snow should be retreating from the area throughout the
afternoon.

Thursday through Monday...

Cyclonic flow over the region on Thursday will give way to a rex
block by Friday, as ridging builds over the Northern Rockies, and
a cut off low moves underneath into the four corners region.
Cooler temps and showers over portions of the area on Thursday
will be followed by above normal temperatures and drier
conditions for Friday through the weekend. More unsettled weather
is possible for early next week with the cut off low lifting off
to the north and east, opening the door for additional weather
systems to move through the region.

High temperatures on Thursday are forecast to range from the
upper 30s to 40s, warming into the 40s and 50s Friday through
Sunday. 30s and 40s for Highs are possible early next week. Low
temperatures in the 20s can be expected most nights through the
extended. STP

.AVIATION...

VFR conditions will prevail into the evening as mid and high
clouds increase ahead of an incoming disturbance and associated
cold front. Rain/snow showers will increase over the
Absarokee/Beartooth Mountains by this evening, with scattered
showers spreading out onto portions of the plains overnight into
Tuesday. VFR to MVFR conditions are possible with the showers,
with MVFR cigs possible behind the front. Mountain obscurations
are likely. STP
