With an area of low pressure still situated just off the south coast of England, scattered showers are expected to develop. Through the morning these are expected to be more isolated and mainly across more western parts of the UK and over North Ireland. Elsewhere, largely dry and feeling warm. Through the afternoon, however, these showers will become more widespread, some heavy and thundery with local downpours. A generally warm and muggy feeling day. Warmest in the southeast with highs around 24C. Cooler in the east in that easterly breeze and low cloud.
Any rain or showers should fizzle out across Scotland overnight but cloud is expected to thicken. Expect cloud to also thicken across western and Northern Ireland but staying largely dry. Rain is expected across southern and central England and Wales as a front pushes northwards. Temperatures falling to around 12 to 16C. 17C in the southeast.
The band of rain will continue to push northwards across England, Ireland, Northern Ireland and eventually up into southern Scotland. This rain should ease off through the afternoon but it will remain rather cloudy across these parts. Across much of Scotland it will be a largely dry day with some sunny spells although some patchy rain is forecast for western parts and the higher ground of Scotland under any thicker cloud cover. It will be a warm and muggy day once again for many. Highs of 19 to 23C. Cooler across central England around 16C.
Weak low pressure persists through Friday sweeping a band of patchy rain northwards across northern England and into Scotland as the day progresses. The far north should be bright for a time until the cloud thickens. Rain will affect western and central Scotland through the afternoon. Meanwhile, elsewhere showery rain, some heavy downpours, is expected to develop in association with the low pressure. However, any showers across southern parts of the UK should fizzle out as high pressure builds in from the south later on in the afternoon. Much of the UK overnight, with exception to the far north of Scotland, should be largely dry. Highs at 24C in the south and 17C in the north.
