.DISCUSSION...

Strong winds across our Western Montana today have caused power 
outages and trees to go down north of I-90. These winds will 
gradually subside through midnight. In addition, there has been 
light snow along the Continental Divide and I-90 west of Missoula.
Visibility in these areas will be diminished due to blowing snow.

Thanksgiving, will see continued wind although not to the 
magnitude or impacts as today. We are watching a disturbance that 
will move through southwest Montana during the morning hours. 
This will initiate another round of snow for areas such as Silver 
Bow and Lemhi Counties with 2 to 3 inches in southwest Montana. 
Models have hinted at light snow showers being as far as the 
Missoula and Bitterroot Valleys although these will be light in 
nature. We have mentioned the winds but it will also be cold 
Thanksgiving morning, so expect wind chills from the single digits
to 10 degrees below zero for locations in western Montana.

Friday evening into Saturday, yet another disturbance will pass  
southeast of our area. Impacts to visibility and road conditions 
should be limited to the Continental Divide. That said light snow 
showers could push as far west as Missoula County.

After the weekend, expect a moderating trend towards seasonal
norms for temperature. An example would be upper 30’s for highs
in western Montana with lows in mid 20’s. There will also be a 
couple chances for light snow showers in the mountains as minor 
disturbances transit our area.

.AVIATION...Strong east to northeasterly winds are affecting GPI,
MSO, and BTM today. Expect these winds to slacken towards 
midnight but return Thanksgiving day, however not as strong what 
occurred today. Expect a wind shift above 2000 to 3000 feet 
through 28/0300 at MSO and GPI as mid level winds are from the 
southwest compared to the surface. Snow showers will continue at 
BTM through 28/0400 and then another period of snow will reduce 
visibility and cause terrain obscurations at BTM and SMN after 
28/0900.
