Temperatures will plummet in the UK’s northern regions next week, while the south will enjoy some autumnal sunshine.
Meteorological autumn officially begins on 1 September and usually sees colder spells develop across the country.
Lingering showers over southern areas will clear on Sunday night, but misty patches are likely to remain.
“It will be fairly chilly in those areas,” said Craig Snell, a meteorologist at the Met Office.
Temperatures will drop to 5C overnight in Northern Ireland and parts of Scotland.
“It will be a nippy start to the new working week,” Mr Snell said.
“But it will be a bright one, for much of the south.”
Cloudy conditions will cover much of Britain on Monday morning, before a band of rain pushes east.
But London and parts of the south east will see highs of 22C.
“It will be pleasant enough for the time of year,” Mr Snell said.
“On Tuesday, we’ll really see a north/south split.”
The Met Office expects conditions to be “mostly dry and bright” in the south and south east.
But heavy rain will fall elsewhere, with wet and windy conditions likely in the north west.
Wednesday and Thursday will both see a mix of sunny spells in the south east and heavy showers in the north.
Temperatures in the south will hit highs of 22C, but overnight lows in parts of the north could hit 2C.
“Through the second half of next week, a cool and showery north-westerly flow is likely.” a Met Office spokesperson said.
“However, there is likely to be a reasonable amount of dry and bright weather around, especially across southern parts of the UK, with the wettest conditions likely to be in the northwest.
“It will often be rather windy, especially in the north, with the risk of gales at times.”
