BBC Weather said Arctic air would keep a hold on the United Kingdom at the start of the weekend, with yellow cold-health alerts from the UK Health Security Agency still in place across a large part of England¹.

The agency’s yellow alerts cover the West Midlands and north-west England until 12:00 Saturday, according to the BBC report, which linked to the UKHSA weather-health dashboard¹.

Saturday was expected to start with another widespread frost, coldest in England and Wales, with town and city lows around minus 2C or minus 3C and countryside readings as low as minus 5C, BBC Weather presenter Sarah Keith-Lucas said¹.

Patchy freezing fog was possible in southern and south-east England, reducing visibility and raising the chance of ice on untreated pavements where super-cooled droplets freeze on contact, the BBC said¹.

Farther north, a breeze was expected to keep most places a few degrees above freezing, the report said¹.

After frost and fog lift, Saturday was forecast to turn largely bright and dry, with afternoon temperatures from about 7C in parts of the Scottish Highlands to about 12C in south-west England¹.

Sunday was expected to be milder and more unsettled as Atlantic low pressure brings showery rain west to east, heaviest in Scotland, Northern Ireland and southern and western England and Wales, with parts of eastern England possibly staying drier¹.

The BBC said the rain could help areas still in drought or severe drought, and it pointed readers to local forecasts on BBC Weather¹.
