Sun to shine in Britain but parts of Northern Ireland may miss out
Many parts of Britain could enjoy Mediterranean temperatures next week - but Northern Ireland could miss out.
Forecasters say the south-east of England could see temperatures hitting the mid-20s by the end of the week - which will be on a par with the Costa del Sol, Rome and Greece.
The Met Office says thermometers will rise gradually, but has warned that fronts from the Atlantic, battling to move in from the west, will mean some areas of Northern Ireland and western Scotland could see more showery weather.
Met Office meteorologist Sarah Kent said this tussle between the warm air from the south and the wet weather in the west - which will bring rain to most places tomorrow - will finally be won by the continental influence on Monday.
Ms Kent said: "By Tuesday across London we could see 18C, maybe 19C. By Wednesday, there's still going to be some patchy rain in parts of the north-west, but England and Wales will have this continental air coming in. So, dry weather for them, plenty of sunshine again.
"The trend into the end of the week is to continue this feed of warmer continental air across England and Wales.
"Those frontal systems are always trying to battle into the north-west, so it could be cloudier there, with some more mixed weather at times."
