Autumn arrives on Monday with a shift to unsettled weather across the UK, the Met Office has said.
Cooling temperatures, rain and wind are expected across the country, the forecaster said.
Temperatures will drop to typical early September levels, starting at 13C to 14C and reaching evening highs of around 20C to 21C.
Heavy rainfall is expected across south-western parts of Scotland. A yellow weather warning for rain has been issued for Dumfries and Galloway, and Strathclyde between 3am and 10am on Monday.
The Met Office warned that homes and businesses could flood and travelling conditions may be poor during that time.
Craig Snell, a Met Office meteorologist, said: "Some of these showers will be on the heavy side, maybe the odd rumble of thunder and some hail mixed in to some of them too, but they will be moving through steadily on a fairly brisk wind in the brighter moments."
Tuesday will see rain developing across south-west England before spreading eastward across most of England and Wales.
“Throughout the day, some of this rain will be quite heavy and persistent, and overall, quite a wet picture for some of us,” Snell added.
“For Scotland, Northern Ireland, the far north of northern England, we just continue the mix of sunshine and the scattered showers, with maybe some sunshine returning later on in the day across the far South West, but still risk of some heavy showers here.”
