.DISCUSSION...

Idaho: Northerly flow will persist over the area today with the
development of afternoon/evening convection. Any storms that develop
will be fairly light with little chance of a wetting rain. A ridge of
high pressure begins to build over the area tonight and becomes the
dominant feature through the weekend as temperatures will be well above
normal by Sunday. A cold front is anticipated to impact the Northern
Rockies between Wednesday-Thursday time frame.

Montana: A weak low pressure system will cause light wrap around
precipitation into southwest Montana during the morning. Then this
afternoon the atmosphere becomes unstable enough to support a few
showers and/or thunderstorms to develop. Any storms that develop
will be fairly light with little chance of a wetting rain. A ridge of
high pressure begins to build over the area tonight and becomes the
dominant feature through the weekend as temperatures will be well above
normal by Sunday. A cold front is anticipated to impact the Northern
Rockies between Wednesday-Thursday time frame.
