Weather Service: Chance of White Christmas? By WestKyStar Staff PADUCAH, KY - According to the song, we dream of a "White Christmas", but what are the real chances of that happening? According to the National Weather Service, the historical frequency of a white Christmas across our region averages about 15 percent (see attached photo). A White Christmas (as defined by the National Climatic Data Center) is one with an inch or more of snow on the ground at 6:00 am, which is when the official snow depth is taken each day. The last White Christmas throughout our region was in 2010, when 2-4 inches fell on Christmas Eve. A very memorable winter storm produced record snowfall on Dec. 22, 2004, halting most travel right before Christmas. •Many parts of southern Illinois and southwest Indiana experienced a White Christmas in 2002. A snowstorm affected much of southern Illinois on Christmas Eve of 2002, bringing up to 8 inches. What about this year? We'll have to wait a little longer to know. Accurate daily forecasts are only issued out to 7 days into the future. A more generalized outlook is available for 8 to 14 days into the future.
