...Reduced Visibilities...

Fog, locally dense in some areas, has developed across portions of
Central and Southwest Montana. While most areas will see
visibilities of between one to three miles where the fog has
developed there will be localized spots where visibilities fall to
as low as one quarter of a mile.

Travelers should be prepared for changing conditions. Slow down
and use low beam headlights if you encounter reductions in
visibility due to fog.
