High pressure begins to build in across northwestern Britain and Ireland while low pressure pulls away toward central Europe. A few showers for England and Wales, but these quite hit and miss, and most places will stay dry. A cool north to northeasterly breeze, strongest around eastern coasts. Mainly dry with variable cloud and sun for Scotland and Northern Ireland, starting chilly. Highs at just 11 or 12C on northeast coasts, more widely 13 to 18C.
Cloud builds over Ireland and the western UK on Monday night with some light, patchy outbreaks of rain developing later for western Ireland and the Western Isles of Scotland. Staying dry though for most with the best of any clearer skies becoming limited to south-central and eastern England. Overnight lows feeling cool at 3 to 8C for most.
High pressure gets squeezed to the southeast as a front edges in from the Atlantic. This brings thickening cloud and outbreaks of rain to much of Scotland, Ireland and Northern Ireland by the end of the afternoon. Increasingly cloudy through the day for England and Wales with a scattering of showers over Wales and western parts of England at times. Staying dry to the east. High temperatures at 14 to 19C.
Pressure is expected to lower across Great Britain on Wednesday following the passage of a rain-bearing front across the country overnight. Outbreaks of rain affect southern areas while frequent heavy and often thundery showers follow from the north. A drier day for Ireland and Northern Ireland. Winds pick up the west and north later. Highs at 13 to 19C, warmest for southwestern Ireland.
