.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:
Upper ridge over the area will help keep mild and dry conditions
around. Prefrontal warming can be expected Thursday. If there
aren`t too many high Chinook arch clouds, the weak November sun
may warm temps to near record levels. The record high for Glasgow
is 63 degrees, last set in 1990.

Then a cold front moves in Friday that will increase winds. A Lake
Wind Advisory may be needed. The front may hang up a bit, bringing
another warm day to the CWA. There may be enough moisture with a
disturbance that moves in late Friday.

Then the 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 precipitation chances late Friday with increasing confidence
Monday-Tuesday. Removed pockets of freezing rain Monday-Tuesday
with Rain and snow mix. TFJ
