.DISCUSSION...
KEY MESSAGES:
- Warm temperatures and dry weather are largely expected over the
  next few days, at least through Tuesday.
- As the ridge breaks down, chances for precipitation begin by
  Tuesday night into the second half of the week.
- There is moderate confidence of a cool down occurring next
  weekend.
WEATHER PATTERN OVERVIEW:
The upper ridge will remain over the northern plains through at
least Tuesday. Temperatures will be above average through Tuesday
as the upper low of the desert southwest opens up and lifts
north. With the weakening of this low and the movement onshore of
the east Pacific trough, moisture will begin to increase across
the region with southwest flow aloft.
On Wednesday afternoon and Thursday night, a few weak shortwave
troughs will lift across the region, pushing a cold front and the
possibility of showers through eastern Montana. Only a small
change in temperature is expected through Friday. There is a
change in pattern for the upcoming weekend for cooler than average
weather, but there remains high uncertainty in the details of
precipitation opportunities.
FORECAST CONFIDENCE & DEVIATIONS:
Used manual edits and NBM90 to increase winds through the early
morning tomorrow. No other deviations. Forecast confidence is
described in the discussion above.
