Tuesday: Outbreaks of rain affect Northern Ireland and northern England. Areas to the north have cool and bright conditions. To the south a warm and humid day develops with sunny spells.
Wednesday: Patchy rain is likely in Wales and parts of northern England. Scotland and Northern Ireland have a cool and showery day. The south will be very warm with sunny spells and locally temperatures could reach 28C (82F).
Thursday, Friday, Saturday, Sunday: Patchy rain clears southeastwards at the start of the period to leave dry but cooler conditions. Later on it probably warms up again in the south and most of the UK remains dry.
Forecast confidence is high falling to moderate later on.
Settled and warm.
A good deal of fine weather is expected in all regions during the course of the week. It is likely to be warm and in the south it may become very warm or even hot. Towards the end of the week the risk of more changeable weather in the north increases.
Forecast confidence is moderate to low.
During the first few days a weather front very slowly pushes southwards and introduces cooler air from the northwest. Through the second half of the week high pressure builds from the west and becomes the dominant feature of the weather.
High pressure is forecast to remain close to the UK throughout the week. It may become centred to the east and that would increase the possibility of very warm air being pulled up from southern Europe. Late in the week more of an Atlantic influence may return to the north west.
