Good article about this event here: https://www.weather.gov/hun/hunsur_2004-02-15
I have a good story about that event. I lived just across the border in McCreary County, KY at the time (north of Oneida) and they called for 8-12 inches of snow starting that night. We were going to church south of Oneida that night (it hadn't started snowing yet) and were seeing cars coming northbound with snow plastered on their front bumpers like they had ran into heavy snow recently, but yet it was completely dry for us. We finally got to the road the church was on and snow just started pouring down harder than I've ever seen. We had to turn around and on the way out several cars were already in the ditch.
By the time we got back home just 20min away it was still completely dry. It never snowed a flake that night at our house despite the 8-12 inches that was forecast. Later on the news we saw where random parts of Morgan County and Crossville area received up to a foot of snow, while we were bone dry. Here's a picture of the snow depth on that day so you can see how finicky the system was.
