.DISCUSSION...

Today through Thursday...

Current analysis is showing broad troughing over the region. This
has brought some cold air advection into the western foothills as
well as some precipitation ahead of the main frontal passage.
With this cooler air moving into the west, this has allowed for
winds to decrease for the Livingston area through the morning.
Isolated to scattered showers will continue through this
afternoon with the front bringing breezy conditions with
northwest wind gusts ranging from 20-40 mph. Lingering showers are
possible (10-30% chance) for eastern MT through Saturday morning
as jet energy exits the state. Accumulations will be minimal
across the lower elevations with snow totals in the
Beartooth/Absarokas around 4-8 inches at the highest elevations
(above 8000 ft) through Friday evening. Ridging will build back
in late Saturday and Sunday. Temperatures will stay in the low 60s
to upper 40s for the weekend. Into late Sunday and Monday a
disturbance is expected to move up into Colorado and Wyoming,
clipping the MT/WY border. A 15-30% chance exists for lower
elevations to get at least a quarter inch of precipitation with
the mountains at a 40-60% chance. Ensembles are differing on how
long this system will stick around as well as the timing on the
next potential disturbance Wednesday into Thursday. High
temperatures will be near average for the remainder of the period
with highs in the upper 30s to low 50s. TS


.AVIATION...

18z discussion...Mountain Wave activity continues this afternoon
along and east of area mountains with occasional sudden gusts of
25 to 40kts possible. Several UUA PIREPS attest to this activity
being present. Away from the mountains mixed winds will bring
gusts of 20 to 40kts out of the west. Low level wind shear is in
the forecast at times into this evening for KBIL/KSHR, and
mountain wave turbulence can be expected near KLVM and KSHR. A
weak cold front moves into the area late afternoon/early evening
diminishing winds and turning them to the northwest. Isolated to
scattered showers will accompany the front through the area.
Shower activity should be limited to a few hours around fropa for
the lower elevations, but may continue into the late night hours
for mountain and foothills locations. Any precipitation will be
very light so no flight category reductions anticipated. Around
sunrise a low stratus deck may work into the KMLS and KBHK
vicinities (~2kft agl). At this time keeping this deck scattered.
