All the signals are aligning to tell us with a higher degree of certainty than usual that the eastern half of the U.S will be cold for Christmas.
This will create the potential setup of a white Christmas in unusual places, as well as in the Midwest. But none of these are a guarantee.
If you see people posting that with certainty this far out, ignore it, but keep an eye out as this may affect a lot of Christmas travel!
And yes, if you're in the eastern U.S. - almost anywhere - I have seen at least 1 model run where you have snow on the ground on Christmas!
I'm not going to publish those, because they're not consistent and should not be considered accurate.
This is the "precision vs accuracy" illustrated in model form. The long weather models provide some precise outputs for where and when it might rain or snow - but they are not accurate at that level.
