It's ALMOST time to write off Christmas snow in these parts.
The saying in weather is "the trend is your friend" -- that is, follow the trend to find out what is going to happen.
Well, the trend is for the Christmas storm to be sheared out -- to essentially have all its energy sucked up by the system behind it.
By the time THAT system is ready to roll through, our cold air is long gone -- which means we see rain the couple days after Christmas.
Is there time for this to change -- yes, but it's unlikely.
Chance of White Christmas: 1 in 200 (down from 1 in 40)
Reasoning: No model support for a storm, despite a favorable setup
