MADISON, Wis. (AP) – Much of Wisconsin will be under a winter storm warning or winter weather advisory as a strong storm heads for the state.  Six to 12 inches of snow is expected across most of western and southern Wisconsin Tuesday, along with blowing and drifting snow.  Even before a flake of snow has dropped, the city of Beloit has issued a snow emergency for Tuesday through Wednesday morning. The declaration activates parking restrictions.   State emergency managers urged Wisconsinites to be ready for the storm with a winter survival kit in your vehicle, a check of road conditions by calling 511 and logging on to ReadyWisconsin.wi.gov.
