In a chilling turn of events, temperatures in the UK dropped to a bone-chilling minus 18.7C on Friday night, marking the coldest January overnight temperature in 15 years. Altnaharra, nestled in the northern reaches of the Highlands, bore the brunt of the cold snap, recording the frigid temperature that sent shivers across the country.
The Met Office confirmed that this was the coldest January night since 2010, a year when the mercury dipped below minus 15C multiple times, with Altnaharra seeing a jaw-dropping low of minus 22.3C on January 8. As the icy grip of winter tightened its hold, other regions also experienced sub-zero temperatures, with Shap in Cumbria plummeting to minus 11C and Heathrow recording minus 5C.
These chilling temperatures are a far cry from the average lows for this time of year, with northern Scotland typically seeing around 0.3C and England hovering at 1.5C to 1.6C in the dead of night. With the UK Health Security Agency (UKHSA) extending its cold weather health alert until Tuesday, concerns about the impact on vulnerable populations, especially those aged 65 and above or with health conditions, have been heightened.
Meteorologist Zoe Hutin from the Met Office cautioned that Saturday night is expected to be equally frosty, with temperatures dipping below freezing in eastern areas. However, a glimmer of hope shines on the horizon as temperatures are forecast to gradually rise from Sunday into Monday, providing some respite from the unrelenting cold.
Looking ahead to the coming week, Hutin emphasized that the UK is in for a milder spell, although temperatures will remain below average. Despite the prolonged cold streak, she noted that the current cold snap has been more prolonged and severe compared to previous years, with each night becoming progressively colder.
As the UK weathers this icy onslaught, the promise of slightly warmer days ahead offers a beacon of reprieve from the biting cold that has gripped the nation.
