The MAIN storm, or upper wave is located in eastern New Mexico and dropping out of the Rocky Mountains, this will force warm air/moisture north, you can see that happening on the video. The color fill on the video is the temperatures at 850mb or 4,100 feet above the surface, this temperature is key in determining precipitation type. Notice the 0°C/freezing line is at the Ohio River, it has at time been drizzling in Evansville, while snowing in Gibson and Knox Co [IN] makes perfect sense given the configuration. the other thing I wanted to point out is across Minnesota, Iowa, Illinois and Missouri. Notice that strong SE push, that is the Arctic Air mass moving SE, it is dense and will slip under all of this tonight, This is why we are concerned about the Winter Weather conditions. Now you know.
