00:00Hi there, Saturday the 9th of September could be the hottest day of the year so far, it

00:06doesn't happen often. As the heat peaks this weekend, 32 or 33 Celsius is possible, followed

00:12by thundery showers for some. Friday afternoon, also hot but not entirely sunny, there is

00:19some high cloud around and some low cloud even across some southwestern coasts and some

00:24eastern coasts as well. There's also the possibility of a thundery shower turning up in western

00:29parts, most especially parts of Northern Ireland. These will be very isolated. For the vast

00:33majority it is a dry, bright and very warm or hot day. High 20s from northern Scotland

00:39down to the south of England and somewhere through the Midlands into south-east England

00:43we'll see 31 Celsius, so I should say 33 is Saturday. Now, towards the southwest a lot

00:51of low clouds continues to lurk on Friday evening and we're likely to see some thundery

00:57showers again move up from the south. Once more, these will be fairly elevated, some

01:03distance between the base of the cloud and the ground, so some evaporation with any rainfall.

01:07There could be some lightning around as well and any showers will be hit and miss. Many

01:12places will stay dry overnight. We've got the mist and low cloud around some coastal

01:16areas but otherwise it's clear skies and temperatures staying at 19 or even 20 Celsius in places.

01:23So some mist about first thing Saturday, some high cloud as well and some of these

01:27showers moving northwards across western parts of the country. Now, a change starts to emerge

01:33into the northwest of Scotland. It turns breezier, cloudier with some showers moving into central

01:38and northern Scotland as well as eventually parts of Northern Ireland. There'll also be

01:42some showers developing as the temperatures rise across central parts of the UK, some

01:47significant thunderstorms. Once again, even if you're in the yellow thunderstorm area

01:52of central England and east Wales, even if you're in that area, chances are you'll stay

01:58dry but there is the risk of some significant thunderstorms developing, 50 millimetres of

02:03rainfall, lightning and hail as well as gusty winds and so on. So that's across central

02:08areas as temperatures rise and temperatures will rise further compared with Friday, 32,

02:13possibly 33 Celsius. That would make it the warmest day of the year so far. It also marked

02:19the peak in the heat because we are seeing a change take place later in the weekend.

02:25This cold front in the northwest brings cooler conditions southwards through the weekend

02:30but it is slow moving. Ahead of that we keep the hot air into Sunday and an increased risk

02:36of thundery showers once again blossoming through the day on Sunday before eventually

02:42into next week. The cooler conditions from the northwest spread across the country, a

02:46significant fall in temperatures back closer to average and more changeable weather on

02:51the way.
