Encouraging changes so far to the GFS 06Z, the Atlantic seems more held back by Xmas eve with better mid-atlantic ridging, let's see if this trend continues. Helen Willets said a chance of things turning colder for Xmas week, she only said a chance and she is right, that chance is there and I am encouraged by the 06Z so far. I wouldn't be surprised to see further upgrades for cold potential in the coming days.
