.DISCUSSION...

Idaho: Dry and breezy conditions are still expected this afternoon
ahead of an approaching dry cold front. The cold front will move through
overnight, and this will likely maintain dry and breezy conditions into
Saturday morning, particularly for the midslopes and ridges. The front
will stall across the southern portion of the Nez Perce NF, producing
another period of near critical winds and RHs. Sunday will be
cooler/slightly higher RHs behind the cold front, though breezy winds
will continue, especially near ridge tops.

Montana: Critical winds and low RHs are still expected this afternoon
ahead of an approaching dry cold front. The cold front will move through
overnight, and this will likely maintain dry and windy conditions into
Saturday morning, particularly for the midslopes and ridges. The front
will stall across SW MT on Saturday, producing another period of
critical winds and RHs for the Beaverhead/Deerlodge NF. The Bitterroot
and East Lolo NF will see near critical conditions on Saturday, but
current models suggest RHs will be slightly higher and winds slightly
less. NW MT should see higher RHs on Saturday, though breezy winds will
continue.
