.DISCUSSION...A beautiful spring day will occur today with high
temperatures well into the 60s under sunny skies thanks to a high
pressure ridge over the area. Toward the end of the day a fast
moving weather disturbance will impact the region through Sunday
morning. Impacts from this system will be an increase in some
gusty winds with scattered showers across northwest Montana. This
will be short lived as:

Sunday and Monday will be under the influence of high pressure
again and bringing some pretty warm weather into the 70s on
Monday. This is about 10-15 degrees above normal.

Unfortunately the warmth and sun will go away as a large area of
low pressure establishes itself over the entire Tuesday through
Thursday. Southwest winds and instability will produce showers and
even a potential for thunderstorms Tuesday afternoon and evening.
Then things begin to crash Tuesday night through Thursday.
Temperatures will drop at least 20 degrees. Precipitation will
become likely across the entire NR with snow levels lowering to
near the valley floors. This system will finally leave the region
Thursday evening. Potential impacts from this system next week:

Significant snows over all mountain passes and higher elevations.
A mix of snow and rain in the valleys. Rock and mudslides are a
potential at the lower elevations.

Expect unsettled weather and temperatures below normal at the end
of next week.


.AVIATION...Expect vfr conditions today at all terminals with an
increase in some mid to high level clouds after 20/0100z
