.DISCUSSION...

Idaho: A ridge of high pressure will be the dominant feature over the
Northern Rockies through at least Tuesday as temperatures warm to around
10 degrees above normal. Then on Wednesday the ridge is anticipated to
break down which will allow for increased winds and thunderstorm
activity. Temperatures cool to seasonal readings with daily convection
anticipated through the end of the week.

Montana: A ridge of high pressure will be the dominant feature over the
Northern Rockies through at least Tuesday as temperatures warm to around
10 degrees above normal. Each afternoon the atmosphere become unstable
enough to support an isolated thunderstorm, especially along the Divide,
with moisture being the limiting factor. Then on Wednesday the ridge is
anticipated to break down which will allow for increased winds and
thunderstorm activity. Temperatures cool to seasonal readings with daily
convection anticipated through the end of the week.
