.DISCUSSION...

KEY MESSAGES:

- Scattered mix of rain and snow is expected through Friday
  morning. Snow accumulations look generally light.

- Dry weather and a warming trend is expected over the weekend
  into next week.

WEATHER PATTERN OVERVIEW:

Upper trough over the west will be moving to the east into the
weekend. A shortwave rotating through the northern portion of the
trough will push a weak system across Montana today and tonight.
With colder air moving in behind this system, any mixed precipitation
will change over to snow on Thursday evening. Snow accumulations
will be generally less than two inches, and could be even less due
to the somewhat warmer ground and the potential for rain at
times.

For the weekend, the flow pattern changes to bring in a warmer
high pressure ridge from the west. This should provide much drier
and warmer conditions into next week.

FORECAST CONFIDENCE & DEVIATIONS:

Confidence is moderate with today`s disturbance as historically
the forecast models can struggle with storms with a northerly
trajectory. Confidence is high in the ridge rebounding and
temperatures warming starting this weekend.
