Does the December 2021 La Nina pattern edge to increasingly wintry scenarios here, with the - or neutral NAO largely persisting through January? The results of the LaNina pattern here: The first 24 days of December showed basically less than half of normal precipitation with temps 2-4F above normal and less than half of normal seasonal snow. Persistence (little change) would be good for heating bills and general travel - free of hazardous road conditions. Not so good for winter weather enthusiasts including skiing-skating-shoveling-plowing. Monthly normal snowfall is 8.8" in CP. Added some CPC graphics at 11A. the 1 month outlook made Dec 16, and the 1 and 2-3 week outlooks made 12/24.
