.DISCUSSION...

Today through Saturday...

Overnight, southwest to west wind gusts of 50 to 70 mph were
observed over portions of the western foothills, strongest from
Livingston to Nye. Expect strong winds to spread into areas along
the US-191 corridor through the morning as a cold front
approaches, causing the pressure gradients to favor west to east
gap areas (Big Timber/Harlowton). The cold front will begin
pushing into northern areas by daybreak, bringing cooler
conditions, isolated to scattered showers and mountain snow
(15-40% chance), and breezy north to northwest winds. Wind gusts
of 40-60 mph can be expected along the western foothills, with
gusts of 25 to 45 mph common across the rest of the area,
strongest in the north. Temperatures mainly in the 50s can be
expected today, a good 5 to 10 degrees cooler than yesterday.
Precipitation amounts are expected to be light, with a tenth of an
inch or less for most areas, and an inch or less of snow in the
mountains. A wind advisory remains in effect for the Livingston
to Nye areas through 8am this morning, with high wind warnings
from Big Timber north through Judith Gap into this evening. Winds
will decrease over the area into this evening, with low
temperatures in the 20s to lower 30s tonight.

Looking at the week ahead, ensembles continue to indicate zonal
flow to weak ridging over the area Monday through Wednesday. A weak
wave moving through the flow will bring low to moderate chances
(20-50%) for showers on Tuesday, greatest over western areas.
As ridging builds on Wednesday, winds look to increase across the
western gap areas. Temperatures in the 50s to lower 60s are
forecast most days with lows in the 20s and 30s at night.
Ensembles point to a trough moving into the Northern Rockies on
Thursday, and potentially another system Friday into Saturday,
bringing additional precipitation chances and cooler temperatures.

.AVIATION...

Strong southwest wind gusts of 45-55 kts over the Beartooth
foothills, including KLVM, will decrease after 14Z to around 25-35
kts out of the W/NW. For all other TAF sites, winds will turn out
of the NW late this morning behind a cold front, with gusts
around 25-35 kts through the afternoon. Stronger gusts around
40-50 kts are expected near K1KM between 12Z today and 0Z Monday.
Isolated showers are possible (10-30% chance) with the frontal
passage. Expect mountain obscuration associated with showers over
the mountains. Archer
