.DISCUSSION...A weak ridge of high pressure has brought plenty of
sunshine across the Northern Rockies. The one exception is the
continental divide where a few afternoon cumulus clouds may
produce a shower or two through early evening.

WEDNESDAY a little more instability in southwest Montana will aid
the development of a few showers and perhaps a thunderstorm over
the central and southern Bitterroot and Sapphire mountains into
southwest Montana.

THURSDAY...The ridge flattens with as a cool front pushes through
the region. The main impact from this front will be breezy
conditions, especially in Northwest Montana. Gusty winds of 20 to
30 mph at times are expected as the front moves through during the
afternoon. A few showers and perhaps a thunderstorm are possible
along this front.

MONDAY as much warmer conditions take a hold of the entire
Northern Rockies. A large high pressure ridge will park itself
over the region. The anomalous high heights will produce
temperatures some 10-20 degrees above normal through Monday. Some
areas could see there first 90 degree day(s) of the year this
weekend. The warmest region will be the lower hells canyon where
temperatures in the mid 90s to possibly 100 are expected.

Many areas have not felt temperatures above the lower 80s all
year so prepare for the heat and remember to stay hydrated.

Next week it`s looking like the potential for afternoon/evening
thunderstorms will increase as the ridge begins to break down with
temperatures returning to near normal by midweek.


.AVIATION...expect VFR conditions at all terminals. A few cumulus
clouds and perhaps a shower are possible along the continental
divide through the early evening hours.
