On the previous day, the 29th, the maximum at Kinbrace was −10.5 °C (13.1 °F) which is the lowest November daily maximum temperature recorded in either the UK or Ireland.[5]
The winter began with a very severe frost on 14 November in parts of southeast England where −8 °C (17.6 °F) was recorded. By the 19th, accumulations of snow were slight, around 5 centimetres (2.0 in) in most places but on the 20th, Jersey recorded a depth of 12 centimetres (4.7 in). It was then slightly less cold until the 27th when it turned very wintry and cold again, especially in Scotland. On the 27th, there was a snow depth of 12 centimetres (4.7 in) in Shetland. Temperatures were below freezing for most places from the 27th-29th. On the night of the 28th/29th, −14 °C (6.8 °F) was recorded in parts of central Scotland. Then, late on the 30th, much warmer air spread in from the southwest leading to exceptionally mild weather. Overall, snow fell on up to 19 days in parts of Scotland.[1]
