High pressure is helping to keep much of the country warm, although the weather will be far from settled everywhere.

A cold front is gradually moving south-east across Scotland and Northern Ireland, bringing a mixture of cloud and brighter spells. 

Rain is also expected to reach north-west Scotland and Northern Ireland later today.

The Met Office has issued a warning as the forecast takes a turn

Things are expected to become more unsettled from Wednesday as a number of weather fronts move across the UK. 

Tony Wisson, the Met Office’s Deputy Chief Forecaster, said there is still uncertainty over the path of one frontal system, which could bring heavy rain to eastern and south-eastern Scotland, as well as parts of northern and north-eastern England.

Southern areas are likely to stay mostly dry, but temperatures will soon take a noticeable dip.

Wednesday night into Thursday could be particularly chilly, with a chance of localised air frost in rural areas as colder air moves in from the north-west.

Thursday should bring long sunny spells across much of England and Wales, although strong winds could affect the far north-west. London may still reach around 22C before another cool night arrives.

With the forecast set to change several times this week, Wisson advised people to “keep an eye on the forecast as the week goes on”.
