With rain amounts likely exceeding an inch for some areas, minor flooding could occur, including a risk of ice jams on some rivers.
Accumulating snow will occur across parts of northern Wisconsin tonight as rain transitions to snow. Snow rates exceeding an inch per hour and visibility restrictions will lead to slippery or hazardous travel across parts of northern Wisconsin overnight.
Although there is a fair amount of uncertainty in amounts, snow chances will increase Saturday into Saturday night. Monitor forecast updates and be prepared for wintry conditions if traveling.
