...STRONG WINDS ARE POSSIBLE REGION WIDE LATE TUESDAY ALONG WITH
HEAVY MOUNTAIN SNOW...

.DISCUSSION...There were a few reports of snow overnight with the
cold front passage and some of this snow IS lingering in
southwest Montana and Lemhi County Idaho. Most of the snow will
end by early afternoon and the region will be cooler and breezy
now that the front has passed.

The next weather system will arrive tonight which has many
interesting aspects. Most locations will start off cold enough
for snow, but the amount of warm air that will move in could only
allow for a short period of valley snow before changing to rain
during Tuesday morning. The moisture does move into north central
Idaho at a favorable time of day so widespread snow will be
possible through Tuesday morning.

One impact with the Tuesday system that could be significant is
wind. All of our model guidance show a strong signature for wind
late in the day on Tuesday. This wind will mix with precipitation
in the mountains which may mean wind gusts of 50-60 mph or more to
cause blowing snow and very low visibilities above 6000 feet.
Lower elevations will also have the threat for strong winds of 50
mph. A strong cold front is also forecast with this system with a
passage overnight that will quickly drop snow levels into
Wednesday morning.

The Northern Rockies will experience a decrease in precipitation
as the cold front pushes out of the region on Wednesday. The best
chance for precipitation will be across southwest Montana and
Lemhi county. Breezy conditions should continue throughout the
region on Wednesday.

A second plume of moisture is anticipated to impact the region on
Thursday. The exact timing and strength of the this feature is
still uncertain, but the overall solution indicates hefty snow in
the higher terrain once again. The mountains have the potential to
receive over a foot of new snow, especially along the
Montana/Idaho border. A fairly strong mid level jet will
accompany this feature causing gusty winds in the higher terrain,
but the models are indicating minimal mixing to the valley floors.
The moisture plume will move out the region sometime on Friday
followed by northwesterly flow through the weekend.

The models diverge immensely on a solution for the next week. One
model is indicating a relatively dry low amplitude ridge of high
pressure over the region, while the other has a significant
pattern change.

.AVIATION...A cold front is continuing its progression through the
region this morning with obscured terrain common. Snow continues
to fall over locations near the divide which will linger through
this morning. Simulated satellite guidance are forecasting cloud
cover to decrease this afternoon so obscured terrain will become
less common.

The next weather system will arrive tonight and will bring cloud
cover and widespread snow by Tuesday morning. Snow levels will
quickly rise on Tuesday and terrain winds may become significant
by the afternoon. Model guidance are showing wind signatures for
the entire region that may lead to the potential for damaging
winds late in the day on Tuesday.
