.DISCUSSION...

KEY MESSAGES:

- Brief cooldown the next couple days before temperatures rise
  back above average over the weekend.

- Temperatures cool down to average next week. Could be a chance
  of precipitation as well.

WEATHER PATTERN OVERVIEW:

Closed Low off the coast of Washington weakens into an open wave
and transits to the south of us tonight and tomorrow. Any
precipitation with this feature will stay in southern Montana,
though a brief shower could clip far southern Petroleum and
Garfield Counties.

Strong ridge of high pressure builds in starting Friday and lasts
through the weekend with temperatures peaking Sunday about 20
degrees above late October averages.

On Monday a larger Pacific trough moves in and will drop our
temperatures back down where they should be in late October. Could
be some precipitation coming with this trough but confidence is
low on when and how much will impact the region. Will continue to
keep an eye on it.

FORECAST CONFIDENCE & DEVIATIONS:

High confidence for temperatures the next few days. Low confidence
on precipitation chances next week.
