.DISCUSSION...
KEY MESSAGES:
- Scattered to isolated showers and thunderstorms are possible
  today through mid-week, as well as periods of wildfire haze and
  smoke.
- A storm system from the Pacific will sustain accumulating rain
  showers and thunderstorms this weekend across our region.
WEATHER PATTERN OVERVIEW:
Even with a warm ridge of high pressure over eastern Montana, the
approaching low pressure system off the US west coast has already
pushed through a few subtle short-wave disturbances, leading to
some scattered rain showers and isolated thunderstorms for our
area at large. This scattered convective activity is expected to
expand in coverage at times over eastern Montana through this
week as approaching Pacific storm system moves into the
intermountain west later this week.
This weekend, the low pressure system will slowly move through the
central Rockies, generating favorable conditions for multiple
rounds of widespread rain showers and thunderstorms for the
greater NE Montana area. Details are still a bit unclear, but 0.25
to 0.50 rainfall accumulations looks possible for many locations.
FORECAST CONFIDENCE & DEVIATIONS:
Deviated from the NBM with more detailed hi-resolution model data
for precip chances and winds for Days 1-2.
For later this week, high confidence in a wet and more active
weather pattern for us locally, but average to below-average
confidence for exact timing and amounts of rainfall.

embedded upper level disturbances that set off these hit-or-miss
storms through mid-week. Periods of wildfire smoke may also affect
visibility.
