Often cloudy with outbreaks of light rain and drizzle across the hills and moors. Turning a little brighter during the afternoon. Feeling increasingly warm, by day and night. Maximum temperature 19 °C.

Outlook for Wednesday to Friday:

Settled on Wednesday with plenty of hazy sunshine. Turning cloudier from the south with a risk of thunderstorms overnight. Very warm and remaining changeable for the rest of the week.

The start of this period is likely to be quite unsettled but also widely warm or very warm and humid, perhaps locally hot in parts of the south and east. Some rain or showers and thunderstorms are likely to affect most parts but there will also be some sunshine. Later in the weekend and into the start of the following week, most parts will become drier but also cooler and fresher. Another brief spell of rain or showers may then affect some parts before high pressure likely builds in more firmly from midweek, and the rest of the following week looks like being mainly dry with variable cloud and some sunshine and mostly warm or very warm. The north may be cloudier with some rain at times though.

High pressure looks like being largely dominant at first, maintaining plenty of mainly dry and warm weather, but with variable cloud amounts. However, although details are uncertain, late June and early July looks like becoming more changeable, with spells of rain or showers probable at times, some of which could be heavy and thundery. Temperatures are likely to be a little above average overall, with brief hot spells possible, these perhaps more likely early in the period.
