.DISCUSSION...Periods of light rain has fallen across portions of
west central Montana much of today thanks to a light northerly
flow. The southern Mission mountains and valley into the Missoula
Valley have received most of the precip however amounts were very
light,  less than .02".

Thick Clouds will remain over the region through much of this
evening. Clouds will begin to thin out a bit overnight in response
to a building ridge of high pressure over the region. Enough
moisture will be left in the atmosphere Tuesday to produce a mix
of sun and clouds. There will be enough clouds over the region
tomorrow to keep temperatures in check around the lower 60s.

This ridge will bring very pleasant autumn weather across the
entire Northern Rockies Wednesday through Friday. Generally clear
with near seasonal temperatures around 70 for day time highs.
Take advantage of this week`s great weather because:

A change to a more active, wet and cool pattern will occur
starting late Friday and persist through early to the middle of
next week.


.AVIATION...Low stratus will impact all terminals through
26/0000z. In addition some light rain is possible at KMSO, KGPI
and KBTM.  A ridge of high pressure will begin to build over the
region overnight through Tuesday however expect a mix of clouds
and sun Tuesday.
