When I first read about this, I had to re-read the graphic because I thought I misread or missed something. After a second go-round, it makes sense. With tonight's expected snowfall, only about an inch for the Rockford area, the National Weather Service in Chicago left a little reminder for drivers ahead of this evening's commute. Take it snow. Sure, the roads are (mostly) clear and have been salted enough to quickly melt the snow but their conditions could still be dangerous despite the insignificant amount of snow expected. U.S National Weather Service Chicago Illinois shared this graphic on Facebook reminding drivers it is conditions like this that can actually be of more danger for traveling versus significant snowfall. The reasons are more traffic on the roads compared to the vehicles that would avoid traveling during a snowstorm.
