Met Office spokesman, Oli Claydon, has said it will be “bitterly cold” tonight.
He said the lowest temperatures will be recorded in rural Scotland and rural northern England where there is snow on the ground, cloudless skies and very cold airflow.
A temperature of -14C would equal the lowest seen in this month last year, recorded in Dalwhinnie in the Scottish Highlands on January 17, 2024.
But a temperature of -16C would be the lowest recorded in January in the UK for 15 years, since -22.3C was logged in Altnaharra in the Highlands on January 8, 2010, according to Met Office data.
