Sunday
A lot of cloud this morning across eastern Scotland and north east England with a few spots of rain or drizzle for a time, shouldn't amount to much. Any early low cloud and mist will retreat to North Sea coasts with the rest of England and Wales dry with sunny spells. In the afternoon a scattering of showers, a few heavy, will develop across Wales and south west England perhaps into the West Midlands. Otherwise it's dry for the rest of the country with sunny spells and warm too. Highs at 20 to 26C.
Sunday Night
Still lots of cloud around eastern parts of England and Scotland in the evening and this will push a bit further inland during the night. Still one or two showers across Wales and south west England as well. Much of England and Northern Ireland should be fine and dry with mist developing overnight. A mild night with minimums of 11 to 14C.
Monday
After a sunny morning across Northern Ireland, showers will develop by the afternoon, some heavy. For the bulk of the United Kingdom it's a rather cloudy morning with showers or some light rain. Lots of showers then affect most places in the afternoon, many heavy with a risk of a rumble of thunder. Still a few showers in the south west through the night, elsewhere it's dry with some mist and fog developing. Expect highs of 20 to 27C north to south.
Tuesday
Very warm and humid across the country today. Showers already in the south west and across Wales will develop across much of the United Kingdom in the morning, turning heavy and thundery for the afternoon. Most of the showers will fade from England and Wales tonight with some rain likely across Scotland. Expect highs of 20 to 26C.
