As the seasons continue to change, and colder weather begins to settle in, we start to see some of the first snowflakes of the season. A strong, Fall cold front will sag across the northern U.S. through the upcoming weekend, bringing much chillier air from Minnesota to Maine. That cold air will pour in over the (relatively) warmer waters of the Great Lakes. As this occurs, as it does almost every fall, light rain and snow develops downwind of the Lakes. Since temperatures will be cold enough, especially at night, light snow will come in bursts for those areas downwind of the the Great Lakes. https://www.youtube.com/watch?v=iPAwyoSDYh8&feature=youtu.be   Areas as far south as West Virginia may also experience light snow through the weekend, as the chilly air plows through. Here's a look at how much snow will fall through Sunday evening.
