UK temperatures to rise to 23C before autumn chill sets in
Leaves littered the ground in Liverpool's Clarkes Gardens on Tuesday as autumnal colours set in across the UK
Thursday will bring unusually high temperatures as warm air wafts across the south of the UK, while colder conditions dig into northern areas.
Afternoon highs in parts of eastern England are likely to be about 5-8C (9-14F) above typical mid-October values, probably peaking at 23C (73F).
It will be a different story further north and west with temperatures in much of Scotland and Northern Ireland sitting around the seasonal norm.
The two air masses are divided by a weather front which will bring outbreaks of rain. As that sinks southwards, chillier air will spread to all parts of the country bringing a colder feel to the weekend, though there will still be plenty of sunshine.
Frost and patchy fog are likely to develop in some locations.
A weather front that has already brought rain to Scotland and Northern Ireland will edge slowly southwards on Thursday, meaning a soggy afternoon for northern England, Wales and parts of south-west England.
To the south-east of the rain band, brisk southerly winds caused by a very deep area of low pressure passing close to Iceland will continue to feed warm air across many central, eastern and southern parts of England.
Sunny spells in these areas will lift temperatures to 19-23C (66-73F) making it feel unseasonably warm for late October.
Thursday's top temperatures will be well above the October norm in southern parts - but chilly weather will be arriving further north.
