Based
on the climate data from 1970-2000, the above graphic from the National
Climatic Data Center shows the
odds of having a "White Christmas" being defined as having
at least 1 inch of snow on the ground.
Since the winter of 1884 and 1885, when snowfall records began
in Nashville, snow has fallen 23 times on Christmas Day. Only 9
have been a measurable amount. A measurable amount is one tenth
of an inch or more.
From a statistical standpoint, there is a 19 percent chance of
a trace or more of snow on Christmas Day, and only a 7 percent
chance of measurable snow.
The last time snow fell on Christmas was in 2002 when a trace
occurred.
The last time measurable snow fell on Christmas was 1993 when
0.3 inches occurred. 0.3 inches also fell on Christmas in 1992
in downtown Nashville, but 1 to 2 inches fell in the Joelton and
Ridgtop areas. 1992 and 1993 is the only time that two consecutive
Christmases have had measurable snowfall.
The last white Christmas in Nashville was in 1969 when 2.7 inches
of snow fell. A white Christmas is one or more inches of snowfall.
The warmest Christmas on record occurred in 1982, and the coldest
was in 1983.
The wettest Christmas on record was in 1987 when 2.37 inches of
rain fell.
Christmas 1984, at 1150PM, a tornado cut a million dollar damage
path from the Whispering Hills section of Nashville to near Una.
