00:00Hello there, certainly a dramatic end to the weekend for some of us with thunderstorms
00:05already developing across parts of Northern Ireland, England and Wales. There is the chance
00:09of seeing further lightning strikes as we head throughout Sunday evening. This could
00:13be accompanied by torrential downpours, hail and strong gusts as well. Increasingly during
00:19the overnight period, our attention also turns to that heavy rain with the showers merging
00:24together into this longer band pushing across Northern England and into Scotland, potentially
00:2930-60mm of rain in just 3-6 hours, that's about half a month's worth for some areas.
00:35So certainly there could be some surface water issues, travel issues and localised flooding,
00:41so do take care if you are travelling over the next 12 hours or so. For Northern Ireland,
00:45England and Wales, the second half of the night will turn drier and we'll see some clearer
00:49spells developing. You might get the odd mist and fog patch forming underneath some of those
00:54clearer spells, but for all of us it is certainly going to be a humid night. Temperatures in
00:59towns and cities holding up around 15-16 degrees Celsius.
01:04So a wet start to the new working week for Scotland, this band of rain gradually progressing
01:08its way northwards, again could be some issues during the morning rush hour here. A drier
01:13and brighter start elsewhere, but the sunshine is strong and it will help develop those showers
01:17as we head into the afternoon. Generally for England and Wales there will be fewer showers
01:22around compared to Sunday and we'll see more of those sunnier intervals, but for Northern
01:26Ireland and areas of Scotland we'll potentially see more in the way of those heavy showers
01:30and again the odd rumble of thunder and some hail is still possible.
01:34It will be breezy around coasts of the Irish Sea and also the Moray Fir fan into the Northern
01:39Isles, but those winds are now coming up from a southerly direction which particularly means
01:44for eastern areas of the UK that it will feel a touch warmer compared to recent days now
01:49that we've lost the cool chilly breeze off the North Sea. So climbing to highs of around
01:5326 degrees Celsius across eastern areas further towards the west still around 22-23 degrees
01:59Celsius which is above average for the time of year and certainly still warm if you are
02:04out in the sunshine. Come Monday evening, any of those showers
02:08that are around will gradually ease their way off, taking longest for parts of Northern
02:12Ireland, North West Scotland, but eventually clearer spells developing here as well will
02:17remain rather humid for many of us, particularly across southeastern areas of England as we
02:21feed in this cloud and rain from the continent. Again, underneath some of those clearer spells,
02:27some isolated mist and fog is possible and temperatures will be holding up around the
02:31mid-teens, but we might drop into single figures in some rural locations.
02:37As we head into Tuesday, our attention increasingly turns to this area of rain that I'm sure some
02:42of you have already spotted that will be gradually pushing its way northwards, again covering
02:47some quite torrential downbursts. Some thunderstorms are also possible, but there is still
02:51uncertainty in regards to the exact track and positioning of this rain, so we'll keep
02:56you up to date with all the latest details, but it is certainly one to watch out for and
03:01again some surface water issues are possible throughout the day on Tuesday.
03:05It will start drier for Northern Ireland and Scotland, but again into the afternoon those
03:10scattered thunderstorms and heavy showers could develop potential for some hail and
03:14strong gusts of wind in there as well. So for all of us, Tuesday is certainly a watch
03:18day for potential issues and hazards as we move throughout.
03:24Generally for the Northern Isles, parts of Lewis and Harris, Tuesday is looking like
03:27a better day compared to Monday now that we've lost that cloud and they'll see some of the
03:30best of the sunshine. Climbing to highs here of 18 degrees Celsius, even elsewhere still
03:36around 23 to 26 degrees Celsius. But if we do end up stuck underneath quite some persistent
03:41clouds and rain, it's not going to be feeling particularly pleasant at all.
03:46As we move throughout the middle part of the week, low pressure that is bringing these
03:49unsettled conditions is gradually going to shift its way off towards the north and east.
03:54So that will allow this area of high pressure to start building its way in. You can see
03:58there are still some showers that want to start bubbling up, but into Thursday there
04:02will be fewer of those showers and they'll be less intense and more of us will get away
04:07with a drier and brighter day. We do though need to be aware that there is still low pressure
04:13waiting in the wings out in the Atlantic and that will want to push towards us as we
04:16move towards the end of the coming week and into next weekend. But we'll keep you up to
04:21date with all the details in regards to that and all the other weather impacts as we head
04:26throughout the coming few days. You can find all those updates across our social media
04:30channels. Download our app as well for all the latest on the warnings and our live radar.
