.DISCUSSION...A ridge of high pressure will continue to build over
the Northern Rockies for the next several days. This ridge will
bring fairly clear skies with steady warming conditions.
Temperatures will be approaching above normal readings by Monday
and into Tuesday. The models are still indicating a slight
possibility of a shower and/or thunderstorms by Tuesday afternoon
across Idaho county.

Wednesday looks to be the warmest day of the week as southwest
flow increases ahead of an upper level trough along the Pacific
Northwest coast. Highs will reach well into the 70s and low 80s
for many valley locations. A few diurnally driven thunderstorms
will also be possible.

Moisture will increase further Thursday and Friday as the area
remains under a broad trough of low pressure allowing for a
growing threat of showers and thunderstorms. It will remain warm
with instability parameters pointing toward a threat of a few
strong thunderstorms containing gusty winds and hail.

Showery and seasonably cool conditions are expected next weekend
as the broad trough remains across the Northern Rockies.


.AVIATION...Patchy fog has developed this morning in a few valley
locations across north central Idaho up into northwest Montana.
This fog will dissipate by mid to late morning. As the ridge of
high pressure strengthens today, expect the mid level clouds to
steadily diminish throughout the day. By this evening, fair
flying conditions are expected.
