.DISCUSSION...High pressure will maintain its hold over western
Montana and north central Idaho through Wednesday. This will
continue above normal temperatures across the region, with many
valley locations reaching into the low to mid 80s. A weak wave of
moisture and energy is expected to move through the ridge
tomorrow, causing mainly increased cloud cover across north
central Idaho in the morning, and western Montana by mid day. A
few showers and possibly an isolated thunderstorms could result as
well, however this activity should mainly occur south of
Interstate 90. Another round of isolated showers and
thunderstorms is expected once again Wednesday afternoon.

On Thursday, a trough of low pressure is expected to begin to move
through the region. This will result in cloudy and breezy
conditions. Fairly widespread showers are expected to develop as
well with isolated thunderstorms possible. A few of these showers
could produce some decent precipitation although confidence in a
widespread precipitation event is low at this time. Cooler shower
conditions will persist into Friday under northwest flow aloft.

For the weekend, forecast models continue to indicate another
ridge of high pressure setting up over western Montana and north
central Idaho. This will result in dry, sunny, and warm
conditions into early next week.


.AVIATION...Optimal flying conditions continue to be in place
across the region for the next several days with the exception of
smoke filled valley in north central Idaho. Winds should be light
with typical terrain driven breezes in the afternoon. An increase
in mid and upper level cloud cover can be expected tomorrow.
