.DISCUSSION...

Idaho: A ridge of high pressure builds over the region early next week
allowing a warming and drying window over central Idaho. However, the
cool air mass over the region will keep temperatures around or just
below average until the end of the week. A few weak disturbances moving
through the ridge will cause some cloud cover and humidity in the 30s to
50s in the afternoons.

Montana: A ridge of high pressure builds over the region early next week
allowing a warming and drying window over western Montana. However, the
cool air mass over the region will keep temperatures around or just
below average until the end of the week. A few weak disturbances moving
through the ridge will cause some cloud cover and humidity in the 30s to
50s in the afternoons with occasional mountain showers.
