Patchy high cloud spilling in may turn the evening sunshine hazier for a time. Clear skies overnight. Remaining breezy overnight, especially along the coast. Very mild, and rather humid. Minimum temperature 13 °C.

Thursday:

Cloud increasing from the west early, with a band of showers moving northeast, these heavy and perhaps thundery at times. Sunny spells developing through the afternoon. Very warm, humid overnight. Maximum temperature 28 °C.

Outlook for Friday to Sunday:

Sunny spells Friday. Heavy thundery showers overnight into Saturday, with further showers possible into the afternoon. Scattered showers Sunday, possibly heavy. Hot on Friday, humid overnight. Weekend likely cooler.

On Sunday, rain and showers will be slow to clear across the north, especially across Scotland and Northern Ireland. Further south, high pressure to the southwest of the UK will extend northeastwards, bringing settled and fair weather mainly across England and Wales. Cloud and rain may hold on for longer across western Scotland and Northern Ireland, while the weather should turn drier and brighter across eastern Scotland where sheltered by high ground. From mid week, high pressure is signalled to dominate much of the UK, bringing dry and fine weather, and feeling warm in the sunshine with light winds for most. Any early morning mist or fog will be quick to clear, and daytime temperature will likely trend around or above normal for the time of year.

High pressure may still be largely dominant at first, maintaining mainly dry and warm weather, with variable cloud amounts. The weather during late June and early July may turn more changeable, with spells of rain or showers probable for all parts at times, and could be heavy and thundery, which is normal at this time of year. Temperatures are likely to be a little above average overall, with brief hot spells possible, these perhaps more likely early in the period.
