.DISCUSSION...

Idaho: A ridge of high pressure will be building over the region for
the next couple of days causing temperatures to steadily warm with
decreasing humidity readings. A few showers and thunderstorms could
develop along the crest of the Clearwater and Bitterroot ranges each
afternoon/evening. These storms will provide little precipitation, but
gusty and erratic winds should be anticipated near the convection. The
ridge begins to break down towards the middle of the week which will
allow for an increase in winds and thunderstorm threat each day.

Montana: A ridge of high pressure will be building over the region for
the next couple of days causing temperatures to steadily warm with
decreasing humidity readings. Even though a ridge is building, the
region will still have a low threat of afternoon and evening showers and
thunderstorms. These storms will provide little precipitation, but
gusty and erratic winds should be anticipated near the convection. The
ridge begins to break down towards the middle of the week which will
allow for an increase in winds and thunderstorm threat each day.
