Low pressure still dominates over the British Isles on Sunday, although this is a much weakened feature with the winds becoming light. A mix of sunny spells and showers will be affecting all parts of the country, with the showers becoming heavy and prolonged at times. There is a risk of some thunderstorms too. Drier for northern and western parts of Scotland and Ireland. Highs at 10 to 18C.
A shallow area of low pressure brings the threat of some very heavy rain across southeast England overnight Sunday into Monday; this slow to clear through Monday morning. Elsewhere there will be sunny spells and scattered showers, a few of them heavy at times on the hills. Highs at 12 to 19C.
Pressure will be trying to rise across the south of the country on Tuesday. This is going to be bringing a fair day here with some good spells of sunshine, although an odd shower cannot be ruled out. Over the north pressure still remains on the low side and showers are more likely to form here, some turning heavy in Scotland. Highs at 21C in the sunshine in southern England, 12C in northern Scotland.
Although confidence in the forecast is lower, it does seem that pressure continues to build through Wednesday. This probably brings fine day to much of the UK, although over Ireland there is the threat of some rain in the west. Highs at 17 to 23C.
Pressure tends to stay high through the country on Thursday. This is going to be bringing more sunshine to England, Wales and Scotland. However, fronts will try to affect Ireland and these may bring some cloud and rain here, some of it heavy in the west. Highs at 18 to 24C.
There are indications that high pressure slips east through Friday. Most eastern and southern areas will be dry with good spells of sunshine. Further west and north there is the chance of some showers or even longer spells of rain. Highs at 25C in southeast England, 19C in more unsettled parts of western Ireland.
