.SHORT TERM...valid for Tdy...Tue...Wed...

Satellite imagery shows strong upper ridge over the high plains
moving east, with a Pacific shortwave along the coast. At the
surface, a lee side trof remains in place with the latest IDA-LWT
gradient at 12.5mb. The western Livingston DOT did report gusts
over 60 mph earlier tonight, but winds are decreasing now in
response to pressure falls to our south and decreasing mid level
winds.

Pacific shortwave will split as it moves inland, and weak forcing
over our region should be enough for some light rain/snow showers
over our mountains late today and this evening. Lower elevations
should remain dry per the downslope winds and dry low levels.

Main issue in the short term is wind Tuesday/Wednesday as a strong
westerly jet moves through the northern Rockies. Impacts will
begin at the gap areas late tonight as lee trof deepens once
again, and could see advisory level gusts by early Tuesday. Winds
really ramp up through the day Tuesday into Tuesday night, and
here there are some model differences with the GFS being strongest
with mid level winds. Given gradient orientation and strength of
mid level flow have issued a High Wind Watch for Livingston and
Nye, with gusts in excess of 70 mph possible.

Tuesday night and Wednesday, decreasing stability with a Pacific
front will decrease the gap wind potential and extend the risk of
strong winds to Big Timber and Harlowton. Core of strongest mid
level flow looks to be in our NW early Wednesday and it looks like
a good chance of 60+ mph gusts. Thus have also issued a High Wind
Watch for northern Sweet Grass and Wheatland Counties.

Steep low level lapse rates behind the Pacific front will spread
strong winds across the lower elevations on Wednesday. Descent
should arrive early Wednesday, so there is some confidence for a
very windy Wednesday. Core of strongest winds currently looks to
be from our NW to south central CWA. This will include Billings
and Sheridan, the latter of which may see gusts over 50 mph along
the east side of the Bighorn Mountains. Keep this in mind if you
have outdoor or travel plans on Wednesday, and it might be a good
idea to make sure outside holiday decorations are secured. Winds
across the area will decrease Wednesday night.

Other than the wind, the mountains will see a period of moderate
snowfall Tuesday night with the passage of the Pacific shortwave.
Looks like up to 4-8 inches in the high peaks of the Beartooth
Absarokas on west-facing slopes. Lower elevations could see brief
light rain showers but this will be insignificant. Livingston may
actually mix with wet snow late Tuesday night. High temps will be
in the 40s to mid 50s, with Wednesday being a bit cooler behind
the fropa.

Windy and mild conditions will keep grass fire concerns elevated.

JKL

.LONG TERM...valid for Thu...Fri...Sat...Sun...

A fast progressive pattern will prevail during the extended period
which starts on Thursday. Due to the fast flow aloft, the models
do not line up well with the many waves in the flow. Thus used a
blend of the GFS and ECMWF for the PoPs, which resulted in a few
changes to the forecast.

The area will be under a high amplitude ridge on Thursday, and a
shortwave trough will approach the area by Friday morning. The
wave will push a cold front through the area on Friday. The
pattern supported Advisory strength winds in the gap flow areas
Thursday through Fri. morning, with increasing winds at Big
Timber. It will be dry through Thu. evening, with low mountain
PoPs late Thu. night. Scattered showers will spread E across the
area on Friday. Highs on Thu. will be in the 40s to lower 50s. On
Friday, highs will be in the 40s, and temperatures will likely
fall during the day behind the front. It will also be windy behind
the front Fri. afternoon. The wave departs the area Fri. night and
conditions will be dry. Models were not in good agreement for
Saturday, but the forecast looked mainly dry and cooler, with
temperatures in the 30s to lower 40s. Brief ridging will be over
the area on Sunday with dry weather, and an increase in wind
speeds in the gap areas. Energy moves through the area for Monday
for a slight chance of rain/snow showers. Temperatures will
continue in the 30s to lower 40s both days. Arthur

.AVIATION...

VFR conditions will prevail today through tonight. Expect some
mountain obscurations over the Beartooths/Absarokas late this
afternoon, and areas of obscuration over the western mountains
this evening. WSW winds will gust into the 30s at KLVM today, and
to around 40 kt late tonight. Arthur
