.DISCUSSION...A weather disturbance will begin to influence
western Montana with a bit more of a breeze into this evening and
a few more clouds tonight into Saturday. However, it appears the
main instability and moisture surge with this disturbance will
mostly be along the Continental Divide and eastward. Winds should
further increase Saturday, but only light to moderate impacts to
western Montana lakes with some choppy wave conditions. From
Orofino to Grangeville...a relatively dry and stable northwest
flow, with light winds is expected into Saturday.

A generally dry northwest flow is expected Sunday with slightly
above normal temperatures.

High pressure should rebuild Monday into Wednesday next week
resulting in above normal temperatures and dry conditions.

There is a lot of model guidance variability during the later
part of next week. Interesting, although, is most of the guidance
is showing a return to showers by Thursday and Friday. However,
how exactly we eventually get to that more moist point is still to
be determined. We have increased showers in the forecasts for
Thursday and Friday of next week.

.AVIATION...Expect mainly VFR conditions at all terminals through
mid day Saturday. A weather disturbance will begin to influence
mainly northwest Montana and along the Continental Divide tonight
into Saturday. Initially, this will produce increasing mainly
ridge winds over higher terrain and a gradual increase in clouds.
The main threat of showers looks to be during the day Saturday,
with only a low probability along the divide for a few light
showers.
