00:00Hi there, following a week of sunshine and heat we're now seeing a thundery

00:05breakdown but as is always the case with thunderstorms they will be very hit and

00:08miss over the next few days and some places will avoid the most intense

00:13rainfall. Low pressure has replaced high pressure and as a result cloudier, cooler

00:17weather is on its way for many parts of the UK. It's already arrived in the north

00:20and the west and we've seen some heavy showers across parts of Scotland earlier

00:24in the day. That turns to more general rain for central and later eastern

00:27Scotland, outbreaks of rain or showers elsewhere and as temperatures rise

00:32through the afternoon chance of some fairly intense downpours just about

00:37anywhere likely to see them but a signal there for southwest England particularly

00:42for central parts of southeast England. Parts of mid Wales and into northern

00:46England over the Pennines for example could see some pretty lively showers

00:51and thunderstorms but still many places avoiding them especially towards the

00:55southeast where temperatures will once again reach the low 30s, much cooler and

01:00fresher further north and west and the rain continues across central and eastern

01:05Scotland overnight with some heavy bursts at times perhaps even a few more

01:10rumbles of thunder with further showers migrating from northern England to join

01:15in as well and a yellow rain warning there in force because of that wet

01:19weather continuing overnight 20-30 millimetres of additional rain. A keen

01:23breeze in the northeast but elsewhere lighter winds and a lot of cloud cover

01:28remaining through the night, a mild night for many 15 to 18 Celsius. Further

01:33showers turn up across South Wales and the southwest of England through the

01:37early hours and some wet weather here first thing if you're caught in one of

01:41these showers it will be heavy and then showers develop fairly widely, more

01:46widely I think, across England and Wales compared with Monday. Again these showers

01:51and thunderstorms will be hit and miss but where they do occur that heavy rain

01:54falling onto dry ground could lead to the risk of flash flooding so a

01:59thunderstorm warning in force over the next couple of days. Still hot and humid

02:04towards the southeast mid to high 20s, much fresher for Scotland and Northern

02:08Ireland where the early rain eases away, drier brighter weather on the way with

02:13some sunny spells coming through in the far north and northwest otherwise for

02:17many it's a grey day with those outbreaks of rain, showers and

02:21thunderstorms continuing into the evening. The focus for the middle of the

02:25week is for showers and thunderstorms to continue in the south, drier towards the

02:30northwest and then more rain on the way later in the week from the west and a

02:36lot of cloud with cooler weather as well.
