.DISCUSSION...

KEY MESSAGES:

- Cold conditions continue today before a strong brief warm up on
  Monday.

- Temperatures will remain above normal but not as warm as Monday
  for the remainder of the week with mostly dry conditions.

WEATHER PATTERN OVERVIEW:

High pressure will drop into the northern plains today keeping
temperatures cold. Temperatures warm on Monday as building ridge
is suppressed by a shortwave moving through the Canadian Rockies
and creating a strong chinook event. The shortwave will briefly
flatten the ridge Monday night.

Once the wave pushes east on Tuesday, the ridge is expected to
rebound keeping temperatures above normal into next weekend. The
ridge moves to the east on Friday with an upper trough expected
next weekend. Models and ensembles have significant differences on
the strength of the trough and whether or not any moisture makes
it east of the continental divide. NBM maintains a mostly dry
forecast for NE Montana at this time but it may change depending
on what models and ensembles do on future runs.

FORECAST CONFIDENCE & DEVIATIONS:

No deviations from NBM made.
