The last of the hot days today, with the hottest conditions expected in the southeast. Unstable air pushes northwards from France and spells of rain are forecast to become more organised on a front that will track northeastwards through the day. The rain is expected to be heavy and thundery in places, these thundery downpours looking most likely over northern England and Scotland but do expect the rain to be heavier anywhere along this front. Southern parts of England will see the driest conditions with any rain passing through quickly. Meanwhile, Ireland and Northern Irerland look to remain largely unsettled with outbreaks of rain expected with the driest conditions to the north and east before rain moves in here. Highs of 31C in the south and southeast, highs of 25C in the north and 22C in the west.
The heavy and thundery band of rain is expected to gradually push offshore overnight with a brief drier interlude behind before more rain, associated with a next low pressure system, is forecast to spread northeastwards across the UK later and into Saturday morning. A warm and muggy night still for many southern and southeastern places at around 17C, although temperatures will be cooler in the west falling to around 12-14C.
With low pressure over the UK on Saturday, expect outbreaks of rain, some heavy at times, particularly across northern and western areas where the rain is expected to stick around for much of the day. Further south and east there will be more in the way of showery outbreaks of rain, some of these heavy although its is forecast to turn drier later on. Feeling fresher in the brisk southwesterly to westerly wind. Highs at around 16-21C.
Staying within a westerly flow and under a trough expect unsettled conditions still on Sunday. With the low pressure centre just off of northwest Scotland northern parts of the UK will see outbreaks of rain, some heavy across Scotland. Elsewhere, it does look to be comparatively drier but still breezy and feeling cooler in that westerly wind. Western parts of the country as well as Ireland will see blustery showers which on that brisk wind are likely to reach across to eastern parts through the day. That ridging high pressure over France, howeveer, stays close by and should see showers largely die out across England and Wales through the evening and overnight. Highs around 17-21C. Cooler in the northwest at 16C.
