Serious cold could make for dangerous driving

BOISE, Idaho (KBOI) - Crews have been working 24/7 since Thursday's snow to clear our roads, and many of the major thoroughfares are looking good. But some streets are still buried under the snow, and this will make for dangerous conditions as temperatures plummet into the single digits.

Colder temperatures inherently make driving on ice more difficult. When temperatures are just below freezing, traffic alone can generate enough energy to melt the snow as wheels roll across the road.

But when we fall into single digits, the heat generated from your wheels is not enough to overcome the extreme cold and the roads stay icy. And it's these conditions that are making people rearrange their schedules.

"I actually brought my wife to work because I was concerned about being out on the roads, as slick as they were. We've had a lot of snow in the last few days and it doesn't seem to be going away very fast," says Mark Wagner, a Boise resident.

And with no significant warmup expected in the next seven days, it doesn't look like it will. State and County crews say they have made every effort to clear as much snow off the roads as possible before the hard freeze comes.

De-icer doesn't work in this kind of weather, so they put a sand and salt mixture on top of the snow to give drivers some sort of traction. But melting the snow is simply not possible.
