Mixed with sunshine and showers, warm at first then fresher next week
A mixed week ahead with some drier conditions but also rain at times. It is likely to be warm for some at first, but by the time some thundery rain arrives at the weekend things will be turning cooler and fresher, with rain and showers into next week. It is worth noting that confidence in the forecast beyond the later stages of this week is considered to be low.

The area of low pressure is expected to drift into Scotland on Thursday. This brings heavy showers or longer spells of rain with it through western Scotland and the northern half of Ireland, breezy here too. A drier start in eastern Scotland but showers and rain arrive here laer. Heavy showers across southern Ireland. Dry with plenty of sunny intervals in much of England and Wales, although increasing cloud with a risk of some showers bursts of rain later in northwest England, Wales and southwest England. Breezy in the west. Highs at 17 to 22C.
Low pressure passes east through Scotland on Friday. This takes outbreaks of rain and showers with it across Scotland and many northern parts of England. More southern and western areas are likely to become drier and brighter with sunny spells developing. Highs at 16 to 24C.
A ridge of high pressure builds eastwards on Saturday. Low pressure in the North Sea may bring a few showers over eastern coasts, but western areas should be drier and brighter with sunny spells. Tops at 17 to 24C.
High pressure tending to fade away on Sunday as a thundery area of low pressure to the south allows for some outbreaks of rain to develop in many areas. A band of rain crosses from west to east with showers following although confidence is low in the detail and timing of this. Highs at 16 to 23C.
More unsettled conditions are expected on Monday with low pressure to the north. Fronts passing east taking cloud and rain with them, most in northern areas. Brighter spells following from the west. A breezy, fresher day. Highs at 14 to 21C.
Low pressure is likely to be staying north of the UK through Tuesday. This brings breezy conditions with sunshine and showers, some of them heavy. Highs at 15 to 21C.
