.DISCUSSION...

KEY MESSAGES:

- Showery conditions again this afternoon and evening along the
  Continental Divide into northwest Montana.

- Warming and drying trend Thursday into the weekend.

Northwest flow aloft continues over the Northern Rockies today,
bringing scattered showers and isolated thunderstorms by this
afternoon and evening as far west as the Idaho/western Montana
border.

High pressure will strengthen along the west coast, gradually
shifting eastwards into western Montana and north central Idaho
Thursday into the weekend. This will lead to a warming and drying
trend, with temperatures reaching back into the 90s for many
valley locations by Sunday. Precipitation is not in the forecast,
though isolated thunderstorms are possible in this pattern across
southwest Montana.
