The monthly mean finished 7.1C, 1C below average and only the fourth cooler than average month this year.

Some 71 hours of sunshine were recorded, 122 per cent of average – the sunniest November since 2007.

Air frosts: 6, Ground frosts: 17, snow falling: 1 (just a few flakes on the 30th, the first November snow in years.)

The start of December looks like it start mainly dry, an anticyclone over the Atlantic that has brought respite from last week’s cold weather will pull away into the continent to be replaced by low pressure. This depression will track across northern England gradually pulling cold, Polar air across the UK on Thursday.

The models go against what has followed dry Novembers in the past – patterns overwhelmingly suggest that December will be average to rather mild and on the dry side. Winter is looking average overall.
