UK set for coldest night of autumn so far
The first frost of the season is expected for some places this week as colder, Arctic air moves across the UK bringing a dip in temperatures. But how cold will it get and how long will the chillier spell last? Sarah Keith-Lucas takes a look.
The UK is bracing for its coldest night of autumn so far as temperatures plummet with the arrival of colder Arctic air. Wednesday night is expected to bring the first frost of the season to certain areas, with minimum temperatures potentially just a degree or two above freezing by dawn on Thursday. Along with the freezing weather, England and Wales are set to receive some much-needed rainfall.
The jet stream, which determines the type of air mass affecting the UK, has been sitting to the north, allowing mild south or south-westerly winds. However, the jet stream will start to sink further south this week, enabling northerly winds to bring colder air. Despite the cold conditions, temperatures will still be near normal for the time of year or slightly below in some areas.
Northern parts of the UK have experienced near-seasonal averages, while the south has been significantly warmer. Frost is likely on grass and car windscreens, with minimum temperatures around 5 to 7C in the coolest areas. A touch of rainfall is expected to spread across England and Wales, with especially dry southern and eastern regions receiving up to half a month's worth of rainfall in just 24 hours.
Although the chilly feel will continue into Thursday, afternoon sunshine may make it feel pleasant. By Friday, milder air will push in, bringing temperatures back up.
