GREENSBORO, N.C. - Today we've gotten a lot of sleet. That's a snow flake, which melts and then freezes again turning into a ball of ice before it hits the ground. To help demonstrate this, think of restaurant crushed ice - basically a bigger version of sleet. You'd think these marble like pieces of ice would make things really slippery on the roads. But what really happens is when your tire gets going on the road, it can actually push this sleet aside and get traction on the road.
Here's the bad side - the longer this sleet sits on the ground and gets pushed together and melted from people driving on it, the more it will be compressed down into one big sheet of ice. So the semi-decent roads we've had so far, are already becoming a giant sheet of compressed ice.
