.DISCUSSION...Gusty south to southwest winds have developed as
expected over most of the area. Wind advisories have been posted
for the evening hours. Clouds are increasing as well as a cold
front approaches across Washington. The cold front will move
through the area tonight with light showers and slowly diminishing
winds. Wednesday will be cooler and remaining breezy in many
areas. The next system approaching from the pacific will spread
clouds across the area with moisture returning to far northwest
Montana by late in the day. After a warm up for Thursday, a cold
front will usher in a wet and cooler period through Monday,
followed by a warmer air mass and decreasing chance of rainfall
through the middle of next week.


.AVIATION...Gusty winds have developed across the area and should
peak 18/0000 18/0300. Winds may reach speeds as high as 40 kts at
times for some of the valley locations. Wind speed shear will be
a concern for both KGPI and KMSO this evening due to 40-50kt west
winds aloft just above the surface.

     Region...Lower Clark Fork Region...Missoula/Bitterroot
     Valleys...Potomac/Seeley Lake Region.
