At around 3:00pm Saturday, ice pellets started to fall and accumulate.
It took until 8:30pm for that to become snowfall - it took a little longer getting to it than originally thought.
That snow continues to fall overnight, and could easily be 5-6" of accumulation by Sunday. Even more is possible, should the snow fall more heavily.
Then, the cold will settle in. The EXTREME cold.
By early Tuesday morning, that could mean a low below zero.
This means in all likelihood we should have a "White Christmas."
