A cool start to Saturday but otherwise the day will be dry as high pressure dominates the weather. Variable cloud is forecast to develop across inland areas through the course of the day but there will still be pleasant spells of sunshine as well. Still rather cool for most, despite being pleasantly warm in the sunshine, temperatures around 15C to 21C.
Many areas dry into Saturday evening with clear spells and then all areas remaining dry overnight with clear spells and variable cloud too. Another cool night, especially in the countryside, but towns and cities not experiencing temperatures quite as low as the previous few nights. Lows 6C to 11C.
High pressure will remain the dominant feature of the weather across the UK throughout the course of Sunday maintaining a lot of dry and fine weather and there is likely to be more sunshine around on Sunday than compared with Saturday. Importantly from Sunday onwards temperatures will end up rising and it will be a warm or very warm afternoon for most in increasingly light winds as well. Highs 18C to 24C.
High-pressure remains in control through Monday. This is going to be bringing another warm day with lots of sunshine. However, a warm front passing through northern Scotland may bring some more cloud here and a few spots of drizzle to western Scottish areas. Temperatures reaching 28C in south-east England, more widely 23 to 26C but only 17C in northern Scotland.
