This time yesterday, they were predicting 6-10 inches (central Kentucky). Today, there's about 1/8" of sleet on the ground and the forecasts have been lowered to "maybe an inch".
This is why I have no respect for meteorologists. If predicting precipitation is an intractible problem, just admit it and move on. Why not just look into the camera and say "Folks, I don't know what the hell it's going to do. It might snow. It might not. Any prediction would be no better than reading tea leaves so I won't waste your time."
