Many people have woken up to the first widespread frost of the season with temperatures in some places dipping below zero.
Temperatures fell as low as minus 2C (25F) in parts of Scotland and northern England on Monday morning as the autumn’s first widespread grass frost spread across the country.
Sunday night saw temperatures broadly plummet into low single figures, with much of the UK waking up to frost on the ground.
Met Office forecaster Matthew Box said: “What we have is high pressure centred over parts of the UK, and that’s bringing a northerly flow across, in particular, eastern parts of the UK, and it’s brought northerly winds and polar maritime air mass across the UK throughout the course of Sunday as well.
“With that cooler air coming down and the high pressure moving slowly but surely eastwards into Sunday night, the combination of that cold air and the clear skies associated with that high pressure are going to allow temperatures to drop off.”
As the day progresses, the coldest temperatures will be felt in Scotland at 9C (48.2F) to 10C (50F), while the south it will be a milder 12C (53.6F) to 13C (55.4F)
It will largely be bright and sunny, but some high cloud coming in across from the West which will cause some hazy sunshine in the north of England and Scotland.
By Tuesday, the cold snap will thaw slightly, with maximum temperatures likely to rise one or two degrees.
