.DISCUSSION...Seasonably warm temperatures will continue these
next few days as high pressure to the south keeps abundant
sunshine across the Northern Rockies. A few afternoon breezes are
expected, especially in the terrain late in the afternoon. A dry
cold front will skirt across the region late Friday afternoon or
evening bringing additional wind into the hot, dry mix. A few
showers or thunderstorms may develop over far southern Lemhi
County or perhaps near Butte as the cold front passes. Otherwise
expect mostly sunny conditions to persist through the weekend with
temperatures running a few degrees below normal for a change.

The high pressure ridge will strengthen once again across the
desert southwest and thus we anticipate our temperatures to
gradually rise to at or slightly above normal next week. Some
model solutions would support the transportation of monsoon
moisture into Central Idaho and parts of Western Montana. But
confidence in these solutions is quite low at this point.


.AVIATION...Mostly clear conditions will prevail through at least
the next 48 hours. Some gusty conditions will be possible at KSMN
late in the afternoon into the evening hours as the atmosphere
mixes. Elsewhere winds will remain generally below 10kts
throughout the day and night.
