Quick look back at Saturday and we saw a 136 degree swing between coldest and warmest.

Changes afoot as we head for Christmas. Flow switches from Polar to Pacific.

Another storm slides into the West bringing a potentially wet Christmas weekend from Seattle to San Diego, snowy into the Sierra and Intermountain West but mild generally east of the Plains.

Looks like snow shall be confined to the Rockies and far NW/N Plains. Track of the low is crucial but looks likely to cross near Minneapolis and stay well north of Chicago.

This track supports mild weather for the majority of the population into the Christmas weekend.
