Significant winter weather for a watch means 5 or more inches of snow and/or sleet within 12 hours, or 7 inches of snow/sleet within 24 hours, or ice accumulation that could cause damage to trees and powerlines, or life-threatening combinations of snow and/or ice with wind.

Southeast Wisconsin is expecting lake effect snow in the next few days as the low temperatures and wind chills continue.

The best chances for snow accumulation will be east of Interstate 75, especially in northeast Tennessee and in the Great Smoky Mountains, according to the National Weather Service.
