Sunday is set to be another fine day for all of the British Isles. There will be prolonged spells of very warm sunshine, despite perhaps a little more cloud present than previous few days, particularly across more northern and western areas. Winds remaining light across many regions though. Very warm or locally hot. Highs 21C to 30C, highest in the south.
Dry weather is maintained during Sunday evening and overnight into Monday with a warm night for many, especially in towns and cities, somewhat cooler across the countryside and near to coastal areas. Lows 11C to 17C.
At the moment fine weather is expected to be maintained across most areas into next Monday as high pressure now looks set to remain the dominant feature. A few isolated heavy showers or thunderstorms can't be ruled out across SW England, but, otherwise dry and very warm conditions will prevail, highest temperatures in the south and west though, 22C to 27C, but turning cooler and fresher across northern areas, nearer 17C to 24C for Scotland, N Ireland and N England.
It is high pressure that will remain the dominant feature maintaining the prolonged run of dry weather across many areas of the UK through the day on Tuesday. Sunny spells, perhaps prolonged are again expected across all areas, despite some variable cloud. Winds more N or NE'ly and, overall, it will be cooler and fresher for many from Tuesday onwards despite still remaining warm or very warm, especially in the south and west, but the very high temperatures more recently won't be repeated. Highs 18C to 24C.
