A seven-day heatwave set to bake Britain in a fine end to the summer will start today with a 25C scorcher.
But first the remnants of Storm Gabrielle will soak the north of the country before most of Britain basks in sunshine as the week continues.
North, north-east and north-west England, Scotland, Wales and Northern Ireland will be lashed by rain for most of today.
However, there will be sunshine in east, south-east and south England this morning, with 25C highs in the south-east, according to Weather Online.
Things will also brighten up in Scotland and Northern Ireland tonight.
Nearly the whole country will enjoy a sunny day tomorrow, although peak temperatures will drop slightly to 22C.
The heatwave will continue on Saturday, with the mercury staying at 22C, before shooting up to 26C on Sunday.
A spokesman for netweather.tv said: “High pressure builds up from the south but ex- tropical Storm Gabrielle is caught up in the flow towards the UK. This will bring a spell of wet or damp weather across the UK on Thursday.
“Caught up in this once tropical system will be some warmer air, and Greater London could see 24 or 25C on Thursday. As the open wave moves away over the North Sea, it takes the warm air with it and a bit of a chill will take hold for Thursday night.”
Met Office forecaster Clare Nasir said: “A dry start to Thursday, a bright one as well with some sunshine.
“This area of rain migrating across Scotland popping over the Highlands, we will see some patchy rain across the eastern part of Scotland and the border regions.
“And then it sort of slides its way south towards northern England. Elsewhere anywhere from south Yorkshire, the Midlands, south-eastwards will see some fine weather to end Thursday with some brighter skies.
“Temperatures doing quite well… 21-24C, feeling warm in that sunshine.”
