The Knoxville area averages approximately 6 inches of snowfall per year, with the heaviest snowfall typically occurring between December and February.
School districts in Knoxville generally announce closures through their official websites, automated phone calls, local TV, and radio stations, with most decisions made by the superintendent in the early morning hours, typically by 5:00 AM on storm days. Two-hour delays and remote-learning days are sometimes used in Knoxville as alternatives to a full closure when conditions are borderline.
Knoxville's geography plays a meaningful role in its winter weather: a humid subtropical climate where ice storms and cold-air damming often drive closures. These factors directly influence how often Knoxville schools end up closed during a given winter. Geographically, Knoxville sits near 35.96°N, 83.92°W, which shapes how regional storm systems and Arctic air masses interact with the area.
Notable historic snow events in or near Knoxville include the historic February 2015 storm that closed Mid-South districts for over a week, which produced widespread closures across the region.
