Montana Weather Summary
National Weather Service Great Falls MT
243 PM MST Sun Dec 17 2017

As of 2 PM it was 21 in Bozeman, 25 in Missoula, 33 in Billings, 35
in Helena, 37 in Great Falls, and 38 in Glasgow. Skies were partly
to mostly cloudy over the Treasure State, while a few mountain snow
showers were impacting Northwest Montana, including Lookout Pass.

Increasing cloud cover is expected from west to east tonight,
leading to abundant cloud cover as Pacific moisture continues to
stream into Montana. Periods of mountain snow are expected in the
western two-thirds of Montana. In addition, some rain and/or snow
showers may impact the Hi-Line and northeastern portions of the
state toward daybreak Monday. It will be blustery, especially east
of the Continental Divide. Lows will reach the 20`s or 30`s for
most, but some readings in the teens are expected in Southwest
Montana valleys.

On Monday, skies will remain mostly cloudy as Pacific moisture
continues streaming into the area and a Canadian cold front, east of
the divide, sinks southward toward central portions of Montana.
Periods of mountain snow will persist, while rain and/or snow
showers are expected at lower elevations. Gusty winds will persist,
especially east of the divide. Afternoon highs will reach the 30`s
or 40`s in most places.
