It’s the last weekend of the meteorological summer or the first weekend of the meteorological autumn, depending on your point of view. But, as August ends and September begins, how will the weather respond? Aidan McGivern has the forecast.

00:00Hello and welcome to the Met Office forecast for the weekend. A weekend in
00:04transition in many respects. For some of course it's the last weekend of the
00:09summer holidays and we do go from August to September that means the start of the
00:13meteorological autumn. It's almost as if the weather knows because it will be a
00:17weekend in which the weather changes from a very wet start in the northwest
00:21to that rain clearing its way eastwards and introducing showery weather and
00:27and cooler air across all parts by Sunday. In other words it's going to feel more
00:32like autumn on the first day of the meteorological autumn. But it's summer
00:36still for Friday afternoon across southern parts of the country. Warm
00:40sunshine to end the day. Meanwhile very wet weather for western Scotland and
00:44Northern Ireland in particular. That rainfall intensifying through Friday
00:48night. Some horrendous conditions if you're traveling through Friday evening
00:52and also that rainfall tending to build up through the next few days over the
00:56higher ground of western Scotland and Northern Ireland in particular. Could be
01:00some localized flooding. Yellow warning in force. The bright colors there
01:04indicating that rainfall increasing further through the night time and into
01:08the start of Saturday. Now let's take a look at what's causing that rainfall.
01:13It's a weather front but it's a weather front that is very slow moving and it's
01:16where these weather fronts combine called a triple point where the rainfall
01:20will be at its most intense as we start the weekend. So it's in this area at
01:24western Scotland. Northern Ireland particularly soggy to start off Saturday
01:27morning. But by this stage it starts to be pushed along by the winds and that
01:32means that it will bring the wet weather to western parts of England as well as
01:36Wales for Saturday morning. Wet and windy as we begin the weekend in western and
01:42northern parts of Britain. Winds touching gale force around exposed western coasts.
01:47Complete different story ahead of the front though because for East Anglia and
01:50the southeast a sunny start to the weekend only gradually clouding over and
01:55the rainfall tending to peter out as it approaches this part of the country.
01:59Rainfall continuing to be steady and heavy for northeast Scotland through
02:02much of the day. But elsewhere for western Scotland, Northern Ireland,
02:06western parts of England as well as Wales we replace the morning rain with
02:10brighter skies but also frequent lively showers brought in by a blustery breeze.
02:16Behind the weather front as the rain clears away we introduce cooler air so
02:20temperatures in the high teens generally. But ahead of the front it is at least
02:25warm for one more day and in one or two spots the sunnier parts of East Anglia
02:3025 Celsius is possible. Now we clear that weather front completely by
02:35Sunday morning and that means actually it's going to be a fresh start on Sunday
02:39and some shelter spots will be down to the low single figures. But plenty of
02:42sunshine for southern Britain. Meanwhile we're going to see even more showers
02:46piling into essentially the northern two-thirds of the UK. North Wales,
02:50northwards it's a very lively day with frequent heavy downpours, thunder and
02:55hail in some of the livelier showers and there'll be a fair few showers pushing
02:59into western parts of Wales and the southwest as well. In between the showers
03:04some drier interludes not that many though for the north. Meanwhile it's
03:08across central and southern Britain where we see the driest weather and say
03:12into parts of the Midlands, central southern England and the far southeast
03:15some places will largely avoid showers and stay dry through Sunday. It will be a
03:20brisk breeze and it will feel a lot cooler I think in the southeast
03:24temperatures only just making it up to 20 Celsius. So a cooler feel for Sunday,
03:29frequent showers for many areas but of course always the opportunity to enjoy
03:34some dry and brighter weather in between the showers. You can keep up to
