Fog rolled in overnight Tuesday, bringing warmer temperatures to the local area. Those hoping for a white Christmas may have to shake a snow globe. The ongoing El Nino weather system will continue to push warmer air into the region, with highs predicted in the 70s for Christmas Day, a record for some areas. Middle Tennesseans have seen a white Christmas 24 times since 1884, the first year records were kept in Nashville, with snow falling in 2010 for our last white Christmas. However, snow may still be in the forecast for January and February – last Christmas, weather was warmer than normal, but quickly changed as we headed into the New Year.
