The beginning of autumn is set to be marked with rainy and changeable weather, the Met Office has said. Monday will see the end of meteorological summer with cooling temperatures, rain and wind expected across the country, the forecaster said. Temperatures next week will likely be around average for early September, starting at 13C or 14C and reaching highs of around 20C to 21C in the evening hours. Heavy rainfall is expected across south-western parts of Scotland, and a yellow weather warning for rain has been issued for Dumfries and Galloway, and Strathclyde between 3am and 10am on Monday.
The UK's mean temperature from 1 June to 17 August is currently 16.2°C, which is 1.6°C above the long-term meteorological average.
The yellow weather warning states, "Frequent heavy showers and thunderstorms are expected for much of Saturday before fading from the west during the mid to late afternoon."
In the UK, weather trends show that by early April, average outdoor temperatures exceed 14°C in most regions. Once temperatures consistently hit around 15°C ... homes will be warm enough without needing continuous heating.
