.DISCUSSION...

Idaho: Fire weather conditions will be near critical levels Friday due
to an approaching dry cold front, which will increase ridge top winds
from the west and bring very dry humidity to the area. The front is
expected to stall over the southern half of the area Saturday, which
could bring another period of wind and low RH for Saturday afternoon.

Montana: A critical fire weather period is shaping up Friday into
Saturday as a dry cold front approaches the area Friday and then stalls
out across SW MT on Saturday. Friday will bring breezy west winds with
very low RHs to most all locations. The cold front passes overnight
Friday, which will likely keep fires active in the higher elevations
well into the night. Critical fire weather conditions may extend into
Saturday for areas near the stalled cold front, primarily south and east
of the East Lolo NF.
