Another shot of light snow Friday

Another snowy coating will grease up roads Friday

Here we go again.

Another minor Clipper system lays down a layer of light snow Friday. This system is moving along at a good clip. It may only snow significantly for 2-4 hours in the Twin Cities. But that will be enough to lay down another greasy inch or so.

Snowfall will persist many more hours across the northern half of Minnesota. Lake-enhancement will boost totals along the North Shore ridgeline.
