Saturday
This morning will be a dry morning right across the whole of the United Kingdom. Mist and low cloud across central and eastern parts of England and Scotland should burn back to North Sea coasts allowing some good spells of sunshine through. Always sunnier towards the west. As temperatures rise in the afternoon there is a risk of a few sharpish showers developing across Wales and perhaps the far south of England. Otherwise it's a fine, dry afternoon with hazy sunny spells. Low cloud and mist may linger close to North Sea coasts keeping it cooler here. Highs of 16 to 20C across Scotland and Northern Ireland, 21 to 25C for England and Wales but just 12C in any cloud along North Sea coasts.
Saturday Night
This evening any isolated showers will soon fade from Wales so most places will end the day dry with some early evening sunshine. Overnight it remains dry with a risk of low cloud and mist in the east filtering into central and southern parts of England. A mild night with lows of 6 to 11C.
Sunday
After a dry start a few showers will pop up across Wales, maybe northern England too. Some rain will also spread into the far north west of Scotland. Low cloud and mist will disperse to sunny spells across much of England. In the afternoon scattered showers may develop across the far south of England, Wales and northern England with a band of rain from north west Scotland to western Ireland. Elsewhere it's stays dry and mostly sunny. Even warmer this afternoon with temperatures climbing up to 26C across eastern England with typically 19 to 24C for most areas. Wet with spells of rain to come across northern Scotland and Northern Ireland, dry across England and Wales with fog patches.
Monday
A cloudier morning across England and Wales but mainly dry except for the odd shower in the south. In the afternoon there is a risk of some heavy, possibly thundery showers across East Anglia and the south east of England. Some rain is likely across eastern parts of Scotland but the rest of the country it's fair and dry. Still a few showers are possible in the south east tonight. Expect maximum temperatures of 11 to 15C for Scotland and Northern Ireland, 19 to 24C for England and Wales.
