Monday
A fair amount of cloud around on Monday, some early sun in Scotland. A front in Ireland bringing thicker cloud here with outbreaks of patchy rain and drizzle, low cloud over western and southern coasts and hills. Some low cloud for western and southern coasts of Wales and southwest England too, a chance of drizzle. Morning showers clear eastern England and then many areas dry although with cloud, but some sunshine in the southeast. Highs at a more muggy 21 to 23C England and Wales, 19C in Ireland, 18C in northern England and 15C in northern Scotland.

Monday Night
Patchy rain increasingly frequent across Ireland and western Scotland into evening, then a front passing northeastward across Scotland overnight brining several hours of rain to most here. The rain could be heavy in western parts. This front will extend into northern England too. Some patchy rain follows the main band of rain in the later hours, mostly in west and southern parts of Ireland and Wales, little expected in central and southern England. Lows of 9 to 12C.

Tuesday
Rather cloudy again for many areas on Tuesday. A front approaching from the west increasingly bringing outbreaks of rain and drizzle to southern Ireland and southwest England and Wales. Elsewhere the day is likely to be dry although a spot of drizzle over almost any high ground, some more rain in northwest Scotland. The rain turns heavier and more persistent in the west through afternoon, this then spreading east across England and Wales into evening. Highs at 24C in southeast England in any sunshine, 17C in northwest Ireland and Scotland.

Wednesday
Low pressure west of Scotland. A southwest flow through all areas with some outbreaks of rain in Ireland, western Scotland and northwest England. Western coasts of Wales and England are likely to be cloudy too. Generally dry in central and eastern areas, although even here a risk of a spot of rain or drizzle, particularly earlier in the day. A few sunny spells in Scotland, mostly east; perhaps some brighter moments in south England too. Highs at 25C in eastern England, 16C in northwestern areas.
