It was the coldest December since 2001, and after a wet start, was generally dry with generous amounts of sunshine. The 'beast from the east' may have disappointed for some, but it certainly didn't disappoint here: the 28th to 31st all had lying snow although by the 31st this had turned to a patchy covering of ice. The mean temperature was certainly below the local 1971-2000 average, and may have also been a fraction cooler than the 1961-90 average- making it two below average months in a row at this location.
In terms of quantity it was only the snowiest December since 2001, but the persistence of snow cover was the greatest since late December 2000.
I awarded the month 63% overall, which is pretty good for December.
