the weather in the capital and pass you to my colleague for the National

forecast. Good evening. It is as if the

weather knows there is a bank holiday weekend ahead. The forecast

is not plain sailing. Often in this country after the heat follows a

country breakdown. The heat peaked for most today, 29, a few places

might see that tomorrow. For the majority, we are already seeing

things change. Thunderstorms are approaching the Channel Islands.

They will make their way into other southern and western areas

overnight, increasing the humidity and how oppressive it feels. A

really muggy night for most of us. See fog likely to come into the

south and east of Scotland. That will change the complexion of the

weather here. The change is under way. We will see a band of them

British hours making their way eastwards and we could get intense

downpours through the morning as it crosses east. The low pressure

becomes slow moving close to Northern Ireland. Come the

afternoon, adding the heat of the day into the

mix, there could see temperatures even higher than today. That will

grow big storms, potentially Scotland, later Northern Ireland.

Northern England likely to see big downpours, North Wales as well. To

the south of that, we keep the heat and humidity. It could be a hot day

for south-eastern parts of England, 28 possibly here. It will cool down

somewhat further south and west, with some cloud around the coast.

The thunderstorms, for The Big Weekend in Hull, there will be a lot

of people on the roads and there could be flash flooding. Large hail,

thunder and lightning. They will rumble on into tomorrow evening

before fading away. Tomorrow night does not look quite as uncomfortable

as the coming night, although still warm. Sunday more promising,

freshening up in the north. The rain gradually clearing away. More cloud

around that we have seen in recent days, tomorrow and Sunday. Later in

the day, with heat and humidity still with us to some degree in the

South, we start to grow more thunderstorms. It looks like Sunday

evening and overnight into Monday could actually be quite a stormy

night. A lot of rain falling in a short space of time, thunder and

lightning and some hail, potentially. There is uncertainty

regarding Bank Holiday Monday and how
