Www.wkrn.com – Alex Libby – 2024-12-18 18:11:00. SUMMARY: In Nashville, the historical chance of a “White Christmas” is only 5%, with at least one inch of snow on the ground or fallen on Christmas Day in just 5 of the past 100 years. The likelihood of any snow (a trace) is slightly better at 17%. The last measurable snowfall on Christmas was in 2010, while the snowiest Christmas was in 1963 with 6 inches. This year, forecast temperatures are projected in the 40s and 50s, making a white Christmas unlikely, with rain predicted instead. The outlook for 2024 also shows an almost zero chance for a white Christmas.
