Monday
A complex and shallow area of low pressure slowly sweeps into Ireland from the southwest, bringing rain and heavy showers, a risk of local thundery downpours. Often raining across central and northern Scotland. Southwest England and Wales will increasingly see outbreaks of heavy, showery rain too. A drier, brighter day in central and east England, but the rain is likely to move eastwards with time. Feeling humid once again. High temperatures to 34C south, much of central England and east Wales approaching 30C. Highs at 20 to 23C northern England and Ireland, nearer 16C Scotland.

Monday Night
Heavy, thundery showers increasingly affect western parts of England and Wales, and likely spreading fairly widely across Scotland. A strengthening wind across Scotland and through the Irish Sea. Some drier spells will form in Ireland but always a risk of showers returning. Central and eastern England will be driest with little cloud, the clearest skies to the far southeast. A mild night with lows of 13 to 15C in northern areas, up to 18 or 19C in southern England.

Tuesday
Tuesday continues to bring outbreaks of heavy, thundery rain to Scotland, northern England, and Ireland. Wind will vary, some notable breezes in the far north and south, and also quite gusty where the showers and thunderstorms form. Starting driest across England, particularly in the east. Afternoon brings an increased risk of showers, most areas at risk as showers push eastward, but local bright drier windows, driest in Kent. Highs at 31C in east England (including towards Yorkshire), 22 to 25C in Ireland, to 16C in Scotland.

Wednesday
Wednesday sees more extensive heavy rain in Scotland; some thundery downpours are probable. Strong winds across Ireland (where may reach gale force), England, and Wales will push plentiful showers onto north and western coasts, and the showers will push eastward with time. South and eastern England, as well as southern Ireland, will be the driest areas with plenty of sunshine, but there is a risk of showers. A cooler day in England with highs at 26C in the southeast, 16 or 17C in Ireland and Scotland.
