Mostly clear skies and cold conditions are expected. Low temperatures will fall to 5 below far north to near 10 above near Lake Michigan.
Clouds will be on the increase on Saturday ahead of a system located over the Plains. A return to southwest winds are expected to boost temperatures with readings in the lower 20s across most of the region. This system is forecast to move across Wisconsin Saturday night and gradually pull away on Sunday. Expect several inches of accumulation which may make for hazardous driving conditions due to snow-covered and slippery roads.
Still looking at the potential for at least 2 inches of snow across most of central and northeast WI from Saturday night into Sunday morning. Confidence is high that snow will occur, but there is still some uncertainly in the exact amounts, particularly the highest amounts which could occur. Regardless, plan for slippery and slowed travel conditions.
