There have been only nine Christmases with measurable amounts of snow since snowfall record keeping began in Nashville back in the winter of 1884 and 1885.
The last time measurable snow fell on Christmas day in Nashville was in 1993 when three tenths of an inch was measured. Trace amounts of snow fell on Christmas in 2002. Statistically there is only a 7 percent chance of measurable snow on any given Christmas. The most snow ever to fall on Christmas in Nashville is 2.7 inches in 1969.
A major storm system is currently over the southwestern united states and will move across the Southern Rockies on Thursday and into the southern plains Thursday night. During the day Friday the system will move from East Texas into Louisiana, spreading wintry precipitation across the middle Mississippi valley with rain across the lower Mississippi valley.
As the surface system moves northeast into Alabama and North Georgia Christmas eve night, colder air gets drawn in behind the surface system. Snow is expected to develop across Middle Tennessee Christmas Eve and continue into Christmas Day.
Climatologically, this is a favored track for snow in Middle Tennessee. Since this event is several days away, uncertainty still remains in the eventual track of the storm system and snow amounts.
