Mrs E lived in Jackson, TN for 10 years before I met her. I moved down there and we got married and stayed another year before moving to Utah.
Whatever happened in Millington, TN (about 75 miles due west of Jackson) wasn't necessarily "normal". Jackson and environs are famous for the ol' business of a mere dusting of snow paralyzing an entire COUNTY for days on end. Schools and businesses shut down and people hibernate in their homes until the snow goes away - which doesn't normally take long.
That part of Tennessee is simply unprepared for snow of any depth.
That said, if I never see another snowflake as long as I live it'll be too soon. The older I get the more intolerant I get of cold, wet, nasty weather.
