One of the hottest Indian summer for a century is set to hit the UK - but not before a few chilly starts.
A large band of cloud and rain is likely to spread across the UK today as western Scotland and Northern Ireland are the first to expect heavy precipitation overnight.
But don't panic - brighter weather is on the way, with some forecasters suggesting it could be turn out to be of the hottest September's ever.
And even today we still have a chance to enjoy a bit of sunshine before thick clouds develop later on.
As the rain spread south-eastwards over night, Monday morning will be cloudy with outbreaks of rain in Scotland, Northern Ireland, Wales and central and western England.
Easternmost England will be mostly dry and cloudy, it will be cloudy with heavy rain in Wales and southern England, while Northern Ireland will see some brighter spells later.
But the UK will heat up after a blustery start to the week when the remnants of Hurricane Dorian pass ove.
Thanks to the Saharan heat plumes, temperatures could even hit 26C this month - that's warmer than Hawaii.
The Met Office thinks the months up to November could be so warm, it will make 2019 one of the top three hottest years on record.
Meteorologist Brian Gaze said: "Computer forecast models support the three-month period ahead being among the warmest on record.
"Indian summer-like settled and sunny weather is forecast to start in a week's time, lasting a week or more and seeing highs up to 26C.
"High pressure is expected to bring a southerly feed, with heat arriving from southern Europe and north Africa.
“The pattern of Saharan heat coming to the UK was big feature of summer this year, and is expected to repeat again.”
The high pressure is to bring blue skies for many, with a few weeks of settled weather.
The Met Office said the south and the Midlands would be sunniest and the north would also see sunshine, but with some unsettled conditions at times.
Saharan heat sent the mercury soaring earlier this summer, with highs of 34C on June 29 at Northolt, north London, and 38.7C – the hottest ever UK temperature – on July 25, in Cambridge.
