Montana Weather Summary
National Weather Service Great Falls MT
325 PM MST Fri Dec 15 2017
Today...Widespread mid and high level cloudiness stayed over the
Treasure State ahead of an approaching Pacific weather system. Rain
and snow also increased over northwest Montana throughout the day,
while areas of fog lingered in the western valleys with fairly light
winds. However, gusty westerly downslope winds persisted east of the
Rockies. Winds of 10 to 20 mph were common in eastern Montana, but
15 to 25 mph winds with gusts of 35 to 50 mph were common along the
east slopes of the Rockies.
At 3 PM MST...Temperatures had only warmed into the 20s and 30s in
the western valleys, but 40s to lower 50s were common elsewhere. The
cool spot was Deer Lodge at 19 degrees, while the warmest reading
was 54 at Denton.
Overnight...The Pacific weather system and its associated cold front
will move through Montana, shifting winds more northerly and
changing rain to snow across much of the state. Light accumulating
snow will be likely across much of western and central Montana. Lows
will generally be in the 20s, but teens are likely in the western
and central mountains.
