.DISCUSSION...

KEY MESSAGES:

- Today scattered rain showers and isolated thunderstorms will
  remain possible. Some storms may be strong to severe.

- This weekend and into early next week, a ridge of high pressure
  will slowly move into our region from the south, bringing warmer
  and drier conditions.

WEATHER PATTERN OVERVIEW:

Weather today continues to be characterized by an axis of
instability interacting with a weak embedded short wave moving
across the region. Marginally severe thunderstorms are expected
again today as a weak front moves across eastern Montana.

Later this weekend and especially by Monday, an upper level ridge
of high pressure builds into the Great Basin with temperatures
warming again. The position of the surface high will generally
keep our region dry.

By the middle of next week, the pattern turns more active with
another trough of low pressure moving into the Pacific Northwest.

FORECAST CONFIDENCE & DEVIATIONS:

Due to the weak forcing in place, exact details of storm timing
and placement and moving are all less than average.

Deviated from the strict NBM to include more HiRes model data to
better represent these details.
