...Patchy fog, freezing drizzle and light snow over portions of
Central and North-central Montana continues this morning...

Patchy fog, freezing drizzle, and light snow continues to reduce
visibility and cause slippery spots on area roadways this morning.
The icy conditions are most prevalent over Fergus and portions of
Judith Basin Counties. Mountain passes and elevated road surfaces
such as bridges and over passes will also see a better chance for
slippery road surfaces. In addition to the slippery roads, patchy
fog may restrict visibility down to a quarter mile at times.

Please use caution when traveling and be prepared for variable
road conditions. The fog and freezing drizzle will likely
dissipate by midday across the area, and rising temperatures will
help melt any lingering ice on road surfaces.
