A warm front pushing northwards across the UK today will introduce warmer, continental air in from the south across much of England and Wales during the next 24-36 hours or so but once again for many north-western districts it remains much cooler and more unsettled with spells of rain at times thanks to low pressure sitting close by. This Atlantic low will push the warmer air back over to mainland Europe early next week but it will never be too far away and will move back into south-eastern England at times during the rest of the week.
Back to this morning and that warm front is bringing a cloudy and damp start to the day across much of Northern Ireland, southern Scotland, northern England and into parts of Wales with outbreaks of rain and drizzle. This dull and damp weather will continue to push northwards across Scotland today, most of the rain out towards western regions where it could turn heavy at times. Meanwhile sunnier skies, already evident across southern and south-eastern England, will make their way northwards today too so that by this afternoon much of England and Wales will be fine and warm although cloud and the odd shower may continue to affect Cornwall and western parts of Wales. Highest temperatures today will be across southeast England, reaching 25°C to 28°C here, but cooler the further north and west that you go with maximums nearer 16°C to 18°C in the far northwest where it will also become rather windy.
Cloud and spells of rain will continue to affect northern and western parts of Scotland and Northern Ireland tonight. Elsewhere, apart from the odd shower over northern England and Wales, it will be a mostly dry night with clear spells. It will be muggy towards the south with lowest temperatures of 14°C to 17°C, nearer 10°C to 13°C in the north and west. Into Monday and many central and eastern areas will see another fine and very warm day although it will become increasingly hazy as cloud moves in from the west in advance of an approaching cold front which will bring outbreaks of rain to many western areas during the course of the day.
