.DISCUSSION...A noticeable change in temperatures will begin
today throughout western Montana and central Idaho. A moderately
strong ridge high pressure will continue to build over the
Northern Rockies through the weekend.

Starting tomorrow, lower valleys in central Idaho, like the lower
Hells Canyon area will begin to see highs above the 100F mark.
Many valleys of western Montana will see highs in the lower to mid
90s. By Saturday and especially Sunday, some western Montana
valleys could also see the 100F mark! We haven`t seen 100 degrees
in Missoula, for example, since the last week of June this summer.

Next week...
As the stable ridge of high pressure breaks down on Monday,
monsoonal moisture will move into the region and will allow
thunderstorms to develop each day. Thunderstorms will be initially
on the dry side, but will eventually moisten up as we get more surges
of monsoonal moisture by the middle of next week. Models have been
very inconsistent on the timing and the location of the
thunderstorms, but nonetheless most areas should see active
weather next week.


.AVIATION....Mostly clear skies and light and variable winds
expected throughout the region tonight and tomorrow.
