It was very wet and unsettled in the first half of the month, but very dry and anticyconic second half. It was extremely wet in the west in the first half of the month. It was relatively dry in the east. A tornado caused devastation in the Kendal Rise area of NW London on the morning of 7 December, injuring six and damaging 150 houses. There was flooding in Scotland midmonth, particularly around the Tay. As the anticyclone grew, there was dense fog in the south before Christmas, causing travel disruption. It became very cold in the NE, with -9.4C at Aberdeen on the 25th; Fyvie had 94 hours of frost. The thick rime at least looked like a White Christmas in many parts. Although some places had dense fog in this period, others had a great deal of sunshine; Aberdeen had 12 days of sunshine. It was exceptionally sunny in parts of the NE; it was the sunniest December on record for Aberdeen (88 hours, beating the previous December record of 67 hours in 1951.) The month ended wet and stormy in the north, cancelling many Hogmanay celebrations. There were gales, thunderstorms, and tornadoes in Northern Ireland.
