Area Forecast Discussion
National Weather Service Glasgow MT
306 AM MDT Tue Oct 7 2025

.DISCUSSION...
KEY MESSAGES:

- Look for a gradual warm up into the middle of the week with
  mainly dry weather.

- The next chance for rain showers looks to arrive over the
  weekend, but greater probabilities and higher amounts will
  remain over the mountains of western, central, and southern
  Montana.

WEATHER PATTERN OVERVIEW:

Upper ridge over the Pacific Northwest will gradually slide
eastward over the next few days. As flow into the region turns
southwest, warmer air will spread into the northern plains.

The eastward shift of the ridge will be aided by an deepening
upper trough over the Pacific Northwest. This system will slide
east for cooler temperatures and wet weather chances increasing by
the weekend. Northeast Montana will be on the eastern fringes of
this weather system however, with greater probabilities for rain,
and possibly accumulating snow over the mountains of Montana.
Temperatures may be cold enough for snow or a mix, especially for
higher terrain in the southwest zones, by Sunday night, if any
precipitation occurs.

FORECAST CONFIDENCE & DEVIATIONS:
Confidence is high on warmer and dry weather for the middle of
the week with ensemble consensus carving out a nice ridge pattern
over the forecast region. Late week, confidence is moderate to
high on the ridge shifting east and wet weather chances
increasing. However, marginal temperatures lend to precipitation
type uncertainties along with precipitation amount issues given
the greater probabilities may be focused south and west of the
CWA.
