.DISCUSSION...
KEY MESSAGES:
- A gradual daily drop in temperatures is expected beginning this
  weekend.
- An approaching low pressure system will bring accumulating
  precipitation to the region this weekend.
WEATHER PATTERN OVERVIEW:
The overall weather pattern will only gradually change as the
ridge of high pressure is slowly pushed eastward by an approaching
trough of low pressure from the west. Today through Thursday, the
warm and dry influence is still around. But starting on Friday,
higher humidity and scattered rain showers will move into our
region from the southwest.
Details are still subject to change, but initially it seems that
the greater precipitation amounts will be across central and
southern Montana through this weekend, before another high
pressure ridge moves in next week.
FORECAST CONFIDENCE & DEVIATIONS:
Deviations from NBM were hi-res blends for temps, winds, and PoPs
through Days 1 and 2.
Confidence is high for the temperatures forecast. Confidence is
medium for the wind forecast. Confidence is medium to low for
precipitation details.
