December 15, 2022 - Snow in the United Kingdom and Ireland

Snow

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.
