YELLOW WARNING OF RAIN for southeast England

Updated at 10:40 on Sat 29 Aug

Valid from 22:00 on Sat 29 Aug

Valid until 23:50 on Sun 30 Aug

Although not all areas will be affected, thundery showers or areas of heavy rain are likely to affect some southern and eastern parts of England late on Saturday evening and on Sunday. The main focus for thundery downpours looks limited to the southeast corner of England overnight but then becomes rather more widespread during Sunday afternoon and evening. Lightning may be an additional hazard.

The public should be aware of the risk of localised impacts from heavy rain and flooding, which may affect travel and some outdoor events.

Further areas of heavy rain or thundery showers may affect parts of southern and eastern England on Bank Holiday Monday, with an additional risk of strong winds developing. It should be noted that there is a larger than average uncertainty in the areas likely to be affected, with updates to this Alert very likely. Meanwhile, the public should be aware of the risk of further localised flooding and impacts on holiday activities.

Will average August turn into sunny September?

It's probably fair to say that we've had a typically British mix of weather this summer, with most areas enjoying occasional spells of warm sunshine among the showers, although the balance did tip rather heavily towards the damp end of the scale across Scotland. There are signs of a change towards a more settled spell at the end of August - just as the last few schools open their doors for the new term.

Keep the brolly handy this week

The weather is dominated by the Atlantic influence this week, with areas of low pressure bringing spells of rain from the west. Some of the rain in the south could be particularly heavy, especially earlier in the week. There will be some sunshine at times too, but a brisk west to southwesterly breeze is likely to make it feel a little on the cool side.

Last Bank Holiday before Christmas

You might think a Bank Holiday Monday would guarantee rain, but in fact it looks like the last day of August will mark the start of a trend towards some more settled weather for the start of the first month of autumn. Still rather breezy with a few showers at first, but as high pressure builds in from the west the weather should become drier and quieter. It will feel pleasant enough in sunshine by day, but calm, clear nights will allow an autumnal chill to develop and perhaps some seasonal mists.

Early autumn or late summer?

It may sound surprising, but the character of our weather during the middle of September is likely to be decided by current weather conditions over west Africa. Groups of big thunderstorms, known as easterly waves, are moving out across the Atlantic from the African coast. These have the potential to develop into hurricanes, and if that happens the knock-on effect of a big injection of energy into the atmosphere is to reduce the predictability of weather across northwest Europe. In other words, there's no clear signal at the moment for the type of weather we can expect across the UK during the second part of September, The best estimate suggests that cool breezes and occasional rain are most likely in the northwest, with warmer and drier weather more common in the southeast.

An ath sheachdain

Onwards through the autumn equinox and the nights become longer than the days, but when might those nights bring the first sharp frosts of the season?
