On December 11, 2022, an Arctic cold blast struck the United Kingdom
and Ireland, crashing temperatures to frigid lows and bringing heavy
snow, fog, and a coating of ice across the region. The wintery event
caused travel chaos across the UK, with more than 7,500 motorists
calling for assistance between December 11-12. More than 40 schools
closed in East Sussex alone, a county on the Southeast coast of
England. With snowfall amounts between 5-10 cm (2-4 inches) reported in
London, drivers were stranded for hours on M25, a major roadway around
that city. At least 300 flights were cancelled, including closures at
Heathrow, Gatwick, Manchester, Stansted, and Bristol. While Ireland
also experienced temperatures as low as -5˚C (23˚F), snow, and freezing
fog, airports were able to continue operation, with delays or
cancellations only affecting flights to or from the UK.

The Met Office reported that December 12 was provisionally the coldest
day in the UK since 2012, with Braemer, in Aberdeenshire, reaching a
high of only -9.3˚C (15.2˚F) and a low of -15.7˚C (3.7˚F). The UK
Health Security Agency (UKHSA) has extended a level-three cold-level
alert through December 16, while a yellow weather warning will continue
for Scotland, Northern Ireland, England, and parts of Wales.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on board
NASA’s Terra satellite acquired a true-color image showing snow still
stretched across parts of the United Kingdom and Ireland on December
14. In the east, heavy snow sits south of the Firth of Forth, a
V-shaped estuary, on Scotland’s eastern coast as well as on the
Scottish Southern Uplands. Part of northern England can be seen south
of Scotland. To the west, clouds obscure part of Northern Ireland,
while a light layer of snow coats both Ireland (south) and Northern
Ireland.
