Thanks Paul.
No , if you trust your reading of the charts, slowly take time and be honest with yourself, you can see what the models indicate across the board. No extreme variants (quite windy up North for 36 hrs). Keeping it simple, high pressure does return quickly with high 850's , therefore not conductive of snow, therefor dry and faux cold weather after boxing day once the winds drop. Up north, Northern England + , high level 300 m, yes snow good probability in late Christmas evening - boxing day period. Scotland no probs. I'm so old , hard to post charts, perhaps younger members can do this for me. I'll try in future, sorry for any offence,
