.DISCUSSION...


KEY MESSAGES:

-  Increased winds and scattered showers on today into Tuesday.

- Rebounding ridge Wednesday into Thursday with lingering showers.

- Cold front Thursday into Friday with cool and showery conditions
  lingering into Saturday


The ridge of high pressure will flatten today as a weak
disturbance makes its way through the Northern Rockies. This
feature will cause increase westerly winds in the higher terrain
especially along the Continental Divide near Glacier NP. Northwest
Montana and areas along the Montana/Idaho border have the best
potential for receiving precipitation today into Tuesday morning.
Snow levels are still anticipated to remain above 7000 feet during
this period, so snow will be mainly confined to the higher
terrain.

The ridge rebounds on Wednesday but models are still indicating a
plume of moisture making its way into north central Idaho and
northwest Montana causing scattered showers. Once again snow
levels will remain high for this time of year, so rain will be the
main precipitation type for the majority of the population.

The models are showing that the cold front will be pushing through
the Northern Rockies late Thursday into Friday morning. The front
will bring gusty westerly winds along with falling snow levels.
Snow could start to cause some impacts to mountain passes by
Friday morning, especially along the Montana/Idaho border. Cool
and showery conditions will persist over the region into Saturday.
Snow levels are anticipated to drop to around 3000 feet by
Saturday morning, so snow could be experienced at most elevations.
