0:00:02 > 0:00:05Hello. With a bank holiday imminent and for many next week's half-term,
0:00:05 > 0:00:07please don't make this the last forecast you see,
0:00:07 > 0:00:10because the details will differ a little from day to day,
0:00:10 > 0:00:12with a thundery breakdown on its way.
0:00:12 > 0:00:15No surprise, because we've had the heat on Thursday,
0:00:15 > 0:00:19temperatures got into the '80s Fahrenheit quite widely.
0:00:19 > 0:00:23We saw temperatures in the high 20s, and Friday will be no different.
0:00:23 > 0:00:25We start with a little bit of sea fog and some mist
0:00:25 > 0:00:27but it takes no time at all to clear,
0:00:27 > 0:00:29and then it's basically a repeat performance,
0:00:29 > 0:00:31although we will see somewhat cloudier skies
0:00:31 > 0:00:34coming in towards the west of Ireland later on.
0:00:34 > 0:00:37But again, 25 to 29 is on the cards.
0:00:37 > 0:00:41It will be a very hot day indeed for many, except on windward coast,
0:00:41 > 0:00:44but even here, UV levels will be high,
0:00:44 > 0:00:48and unusually, very high levels of UV are forecast again on Friday
0:00:48 > 0:00:50in southern areas.
0:00:50 > 0:00:53Then we start to see that change.
0:00:53 > 0:00:55Now, the detail will be quite difficult
0:00:55 > 0:00:57with this thundery breakdown, as it always is,
0:00:57 > 0:01:00but it looks as though we'll see those thundery showers
0:01:00 > 0:01:02coming in to the South-West and Northern Ireland,
0:01:02 > 0:01:04so a really quite uncomfortable night,
0:01:04 > 0:01:07because obviously the humidity will be a lot higher once again
0:01:07 > 0:01:08with all those showers falling.
0:01:08 > 0:01:11So yes, it is a hot and humid start to our bank holiday weekend,
0:01:11 > 0:01:14but that thundery breakdown will occur gradually,
0:01:14 > 0:01:16different areas, if you like, at different times,
0:01:16 > 0:01:18before it finally freshens up.
0:01:18 > 0:01:21So for Saturday, it looks as if we'll start with the showers
0:01:21 > 0:01:23running across parts of England and Wales
0:01:23 > 0:01:27but perhaps stagnating a little more across parts of Northern Ireland
0:01:27 > 0:01:28and then Western Scotland,
0:01:28 > 0:01:31so it really could be quite a wet day in these areas.
0:01:31 > 0:01:33Some quite severe thunderstorms are forecast,
0:01:33 > 0:01:35but ahead of it there'll be some very nice weather, and behind it,
0:01:35 > 0:01:39as it freshens up, as well, some decent sunshine will come through.
0:01:39 > 0:01:42So it's not a wash-out, although it doesn't look particularly pleasant
0:01:42 > 0:01:43for much of the day in Northern Ireland
0:01:43 > 0:01:46and western and southern Scotland. It's still hot,
0:01:46 > 0:01:49we've still got some humidity around to break down. So those storms
0:01:49 > 0:01:52will continue to rumble on through Friday night into Saturday
0:01:52 > 0:01:54before pulling away. High pressure starts to build then
0:01:54 > 0:01:58but we've got this next area of low pressure coming in to the south,
0:01:58 > 0:02:00so it could be that we see a second thundery breakdown,
0:02:00 > 0:02:03this time more likely across the southern
0:02:03 > 0:02:04and eastern part of the country.
0:02:04 > 0:02:07Later in the day on Sunday and into Sunday night
0:02:07 > 0:02:09it looks very thundery indeed, at the moment.
0:02:09 > 0:02:12Of course, by that stage, it's freshened in the north
0:02:12 > 0:02:15and it's a slow improving picture as high pressure takes over,
0:02:15 > 0:02:17but not in the south. This is Sunday night and into Monday.
0:02:17 > 0:02:18It looks like we could have
0:02:18 > 0:02:21some really torrential downpours once again,
0:02:21 > 0:02:24some large rainfall coming down from those intense storms.
0:02:24 > 0:02:26And they will take a while to clear away.
0:02:26 > 0:02:30Still a lot of heat and humidity left around, even into Monday.
0:02:30 > 0:02:32These temperatures are probably quite conservative,
0:02:32 > 0:02:35we may see a few degrees higher than that, actually,
0:02:35 > 0:02:37where the sun comes out for a long time. And it should do,
0:02:37 > 0:02:40with high pressure around across many areas.
0:02:40 > 0:02:41Still, though, that weather front with us
0:02:41 > 0:02:44across the eastern side of the country even into Tuesday
0:02:44 > 0:02:48before we finally start to see that thundery weather clearing
0:02:48 > 0:02:51out of the way, and then we will see a few scattered showers elsewhere,
0:02:51 > 0:02:54and temperatures back down closer to normal.
0:02:54 > 0:02:55I think for most of the week
0:02:55 > 0:02:58they will stay above where they should be for this time of year,
0:02:58 > 0:03:01so more strong sunshine coming through.
0:03:01 > 0:03:03And with high pressure building from the midweek onward
0:03:03 > 0:03:07it looks set fair. It won't be as hot as it's been this week,
0:03:07 > 0:03:10but pleasant enough, until late in the week.
0:03:10 > 0:03:12And this is where we think we'll get back to
0:03:12 > 0:03:15a more mobile weather pattern as we head towards next weekend,
0:03:15 > 0:03:16when the low pressures
0:03:16 > 0:03:19start to usher in weather fronts from the Atlantic.
0:03:19 > 0:03:21That's when we'll see rain at times,
0:03:21 > 0:03:25but initially, midweek it will become settled and quite warm again,
0:03:25 > 0:03:27but there's that thundery breakdown before then.
0:03:27 > 0:03:30And as ever, you can get more on the website.
