First, let’s define the “official” meaning of a white Christmas. According to the National Weather Service, you have to at least have one inch of snow on the ground Christmas morning to be considered an official White Christmas. In the Miami Valley, that has happened 21 times in the last 123 years (since records have been kept in our area). The last time we had any snow on the ground was in 2013 when a trace was measured on the ground. Later that season, the “polar vortex” would become a popular term as winter kicked into high gear in early 2013. Despite that coating of snow, it wasn’t officially a white Christmas. For that, you have to go back all the way to 2010 when there was 2 inches of snow on the ground and just under a ½” of snow fell on that day.
Do you remember the Christmas of 2004? Chances are if you’ve lived around this part of Ohio, you would remember it well. That year we had a record 16 inches of snow on the ground Christmas morning. Areas across the southern Miami Valley into southeastern Ohio were devastated by a major ice storm which left four people dead and over 675,000 people without power. On top of that, a record low temperature of 17 degrees below zero was set on that day. Ouch!
