Temperatures will halve tomorrow, making it colder than Christmas Day as 50mph polar gales from Iceland blast the UK.
Rain has been forecast by the Met Office and gales of 50mph are expected to batter Scotland.
Southern and northern England will see 30-35mph winds.
The Met Office forecast 14-17C highs on Saturday in northern England – making parts cooler than the 15C in Hull, East Yorkshire, on December 25 last year.
Met Office forecaster Nicola Maxey said: “Northern England and Scotland see temperatures edge below average on Saturday.
“Low pressure from the North means a difference of at least 10C in temperatures from midweek.
“The weekend looks unsettled, with strong winds in Scotland and rain in the West and far North – and next week looks changeable, with heavy rain possible.”
The Weather Outlook forecaster Brian Gaze said: “It’s a disappointing Midsummer’s Day, with parts looking even colder than Christmas Day.
“Colder air is being pulled down from Iceland, making it a big contrast with heat earlier this week as some places see temperatures almost halve.”
