.DISCUSSION...

KEY MESSAGES:

- An overall ridging pattern will keep temperatures well above
  normal through Friday with minimal chances for any measurable
  precipitation.

- Temperatures cool over the weekend to slightly above normal
  with dry weather.

- Rain and snow possible Monday and Tuesday next week.

WEATHER PATTERN OVERVIEW:

A surface high pressure system will be over the area today with
dry weather and light winds. Upper ridge will also be building
into the area today which will bring near record highs on
Thursday. While the ridge gets flattened by an upper trough moving
across the Canadian Prairies on Friday, the unseasonably warm air
remains until a cold front passes through the forecast area Friday
night. There may be enough moisture with this system for a slight
chance of showers. Between today and Friday, there will be on and
off high clouds during that time depending on how much chinook
arching occurs off the lee side of the Rockies.

Ridge rebounds for the weekend with dry weather. Temperatures will
be not as warm but they will still be above normal for mid
November.

An upper level trough will move into the west coast on Friday.
Models move this trough inland over the weekend. It looks like it
will be Monday this trough reaches northeast Montana with any
precipitation chances.

FORECAST CONFIDENCE & DEVIATIONS:

Made deviations to winds and wind gusts mainly on Friday to
increase wind speeds. There is high confidence in temperatures
being very warm on Thursday and Friday. There is low confidence
on and precipitation chances Friday afternoon and evening.
