For the UK as a whole, temperature and rainfall for December were near-average, but there were marked spatial contrasts and a wide range of weather conditions throughout the month. Westerly airflows brought strong winds and some heavy rain and snowfalls, resulting in a wet December for the north-west, while in southern and eastern areas it was generally dry and sunshine was well-above average. With mild airflows from the Atlantic, temperatures were often high for the time of year, but there were cold spells early in the month and during an anticyclonic episode in the last week, which brought the lowest minimum daily temperatures for 2014.
