Wettest west & north
The jet stream will be over the top of the British Isles during the week ahead, driving Atlantic weather systems across the country, bringing periods of rain or showers, and blustery winds. Temperatures on the cool side in the west & north, although some warm and humid days are possible in the south & east.

Low pressure to the north-west and high pressure to the south of Britain. Outbreaks of rain or showers in the west & north-west, but largely dry and sunny in the south & east. A small secondary low developing over the Atlantic brings more organised rain to Ireland later, extending to south-western Britain late in the day. A freshening south-westerly breeze. Warmest in east & south-east, highs 17 to 23C.
Confidence of detail is low, but a changeable pattern is likely to continue over the weekend. Fronts moving across the country from the south-west are likely to bring outbreaks of rain to most places, at times persistent, particularly in the west & north-west. Meanwhile, east & south-eastern areas should escape more often dry, and feeling warm in spells of sunshine. Breezy, south-westerly winds. Highs 17 to 24C.
Remaining mixed, although precise detail is uncertain. Areas of rain or showers, mainly focused toward the west & north-west, whilst a waving frontal system may influence southern regions giving a spell of rain. Occasional sunshine breaking through, feeling warm and humid in the south-east. South-westerly winds. Highs 16 to 19C north & west, 22 to 25C south & east.
A continued changeable south to south-westerly pattern. Areas of rain or showers mainly toward the west & north-west, but a few pulses of rain are possible almost anywhere. The south & east should stay drier, brighter and warmer. Highs 17 to 25C.
Remaining mixed, with fronts trying to spread from the west, bringing a risk of rain, but again eastern areas should fare best for dry weather. Highs 17 to 24C.
Further areas of rain or showers spreading from the west, whilst eastern areas are likely to stay drier and warmer. South-westerly winds. Highs 17 to 24C.
