Monday
A front passing gradually eastwards across England and Wales during the day brings a band of persistent rain, some heavier bursts, most prolonged over central-southeastern counties into the afternoon, only clearing East Anglia later in the day. Rain breaking up in the west with skies brightening, sunny spells develop, but a few brief showers possible. More generally showery for Scotland and Ireland, some heavier showers into the afternoon, chance of local thunder, and rain increasing in the west later. Varied west-southwest winds. Highs of 13 to 15C Scotland and Ireland, to 18C southeast England.

Monday Night
Showery rain becomes increasingly frequent across Ireland and west Scotland into evening and later spreading further south too. The showers will be largely confined to western areas where some persistent heavy falls are increasingly probable. A few showers will drift eastward, but these will be well-scattered; some periods of clear skies likely in eastern areas too. Lows of 7 to 9C.

Tuesday
Blustery westerly wind on Tuesday with a mix of showers and sunny spells. Early in the day, most showers will be in western areas, then showers developing more widely into central areas into the middle of the day, extending further eastwards by afternoon - some thundery downpours possible in northeast Scotland and eastern England. The showers easing from the west into the evening with some sunny spells breaking through. Highs at 12C northwest Scotland to 18C southeast England.

Wednesday
Pressure rises a little on Wednesday, but showery rain will still affect western areas in the morning, extending eastward across northern parts of England and Scotland during the day, but not as heavy as previous days. A few mostly light showers for Ireland. Well scattered showers over central and southern England, mostly toward east later in day, locally heavier. Variable cloud, some sunshine, best near western coasts in afternoon. Highs at 13 to 19C, warmest southeast.
