WSIL--White Christmases bring many joy, but to those traveling on the roadways, holiday snowfall can cause headaches. The region's last white Christmas was in 2004, and another may be on the way.
Just days before the holiday on December 22nd, 2004, 18 to 24 inches of snow fell on Evansville and southwestern Indiana, and 10 to 20 inches blanketed southern Illinois, western Kentucky and southeastern Missouri. Despite some melting, there was still nearly a foot of powder on the ground Christmas morning.
According to the National Weather Service, to be an official white Christmas, at least one inch of snow must be on the ground at 6 AM Christmas morning. On average only 15% of Christmases are officially white in southern Illinois.
