BOZEMAN, Mont. -

The brunt of the winter storm had not yet reached the Gallatin Valley by Sunday night. That meant light snow in the Bozeman area and some fairly mild temperatures into the afternoon, leaving roads wet. As the sun fell so did the temperatures, setting up a possibility for black ice.

We headed to Four Corners to speak with drivers who were coming from every direction. Drivers like Stewart Cook tell us the drop in temperatures is what concerns him. He lives not far off Norris Road.

"Norris road was just wet, it was mostly dry and wet in spots when we came into town around 4p.m," said Cook.

This time of year when snow and ice can linger, it can make for dangerous driving conditions.

"Just the temperatures dropping and becoming freezing especially in the shaded areas," said Cook.

It is a concern other drivers share. Billie Rhodes spoke to us at that same gas station in Four Corners, telling us she lives just down the street.

"Some of the side roads are a little slick and a little icy," said Rhodes.

She explained to us that the Montana Department of Transportation does a good job maintaining the roads, but when conditions change quickly you never know what to expect.

"Black ice is always a concern when it drops temperatures like this," said Rhodes.

Sunday night the edge of the bulls eye was in the Butte area, troopers responded to at least 10 slide offs and multiple crashes in that area. This is something for Gallatin Valley drivers to be prepared for as the storm moves east.
