Overview

This page provides a meteorological overview of the March 12, 2022 significant snow event that dumped several inches of snow across most of the area, even in the lower elevations. This was a very unusual late-season event and was the most significant widespread March winter event in the region since the '93 Blizzard/Storm of the Century. This event also produced the most single-day snowfall at the Knoxville climate site (6.5") since the 1993 storm as well. The combination of high snowfall rates and strong winds did lead to scattered power outages, in addition to difficult travel. Thundersnow also occurred in portions of the Central and Southern Valley as a result of the very strong lift and sufficient instability.
