Southern parts have drawn the short straw again and will see more heavy downpours during the coming days. Head north and it'll soon turn increasingly warm and sunny with temperatures into the mid-twenties by Tuesday.
So often when we're talking about a split in the weather across the British Isles, it's a northwest to southwest one, with those in the northwest tending to see the wetter, windier weather. But, for the second time in a couple of weeks, the weather action is going to be increasingly focused on the south of the country during the coming days as a low pressure system stalls nearby.
Further north, with the Azores high displaced away from the Azores and situated out west of Ireland, it's that which is going to play more of a role, particularly as it'll regularly try to ridge further east, towards the UK and Ireland. It then looks set to eventually move further east and perhaps ridge towards Scandinavia later in the week.
The start of the weekend hasn't brought many differences across the country though, with many parts cloudy and some bits and pieces of rain here and there. The sun will break through more during the day on Saturday though, and that's liable to help trigger a scattering of potentially sharp showers in southern and central England. They'll not be as widespread as on Friday though.
Through the evening and overnight will see a more widespread batch of showery rain making a move up from the south though, with some hefty, thundery downpours likely to continue to pulse north through the night and into Sunday. Their northern extent is a little uncertain but they could well move up into the Midlands, southern and central Wales and into East Anglia. Not everyone is liable to catch the heaviest bursts, but if you do you're likely to know about it, with some torrential downpours possible.
The rainfall map for Sunday tells some of the story at least, but don't be too surprised if the boundary of the wetter weather is a touch further north, particularly later in the day and overnight Sunday.
Meanwhile, out of that showery, wetter zone Sunday will see sunny spells, and barring a few showers in the northwest of Scotland and maybe some patchy rain near to northeastern coasts, it'll be dry with sunny spells. Temperatures will widely reach up into the high-teens or low-twenties.
Monday will see very little change in the setup, with low pressure hanging around over Northern France. Once the residual showers from overnight have cleared from central and southern England though, many parts should actually be mostly dry. So, potentially good news for the start of Wimbledon, but not a nailed-on certainty that they'll get away with a dry day as showers may bubble up in southern parts, with another batch also likely to start to drift north off of the continent later on and overnight. Temperatures will be similar to Sunday.
Into Tuesday, the overnight downpours in the south may still be in situ in places during the morning, with reinforcements likely to arrive during the day from the southeast, into southern and perhaps also central parts. Head north though, and there'll be plenty of sunshine with western Scotland likely to be the place to be, with highs making it up into the mid-twenties 24c is currently forecast in Glasgow as an example. Not bad for the first week of the holidays north of the border, although it will be cooler and cloudier near to eastern coasts.
