London (Greater London) weather

Headline:

Monday, dry with bright or sunny spells.

This Evening and Tonight:

Any isolated showers at first this evening will soon die away to leave dry conditions overnight with some lengthy clear spells developing. Winds will be generally light. Minimum temperature 9 °C.

Monday:

A largely fine and dry day with bright or sunny spells. Cloud amounts will increase during the day, with the best of the sunshine likely towards East Sussex and Kent. Maximum temperature 20 °C.

Outlook for Tuesday to Thursday:

Tuesday, cloudy with a few showers turning drier and brighter. Wednesday, generally fine and dry, turning very warm. Thursday, very warm and humid with potentially heavy and thundery showers.

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.
