Light to moderate snow will continue to move east through the area into this evening, continuing to affect the evening commute. The green areas on radar are likely showing moderate snowfall rates up to 1/2 inch per hour, along with reduced visibility values to around 1 mile. The snow will continue to accumulate on roads during the evening commute, leading to slippery driving conditions. Prepare for snow covered and slick roads for the evening commute.
Snow, briefly moderate to heavy at times, will continue into this evening before coming to an end. It'll then turn windy for tomorrow.
Here is a map of the road conditions on the major highways across the area, from the Wisconsin DOT 511 website. There are several areas with slippery road conditions, due to the snow falling on road surfaces. Slow down if driving this evening in the snow!
