SHEBOYGAN, Wis. (WHBL) - Roads and streets throughout the Sheboygan area are snow covered and slippery this morning.  There is blowing and drifting in the rural areas and some schools have delayed the start of classes.  County Highway Commissioner Greg Schnell says some roads that have been cleared can be ice covered and very slippery.  On others, drifting can be a problem.  He says there were a few reports this morning of vehicles stuck in the roadway.  In one case they had to send a county plow to get the wrecker to the stuck vehicle.
