Bit of a slump for the end of June

This week looks unsettled and cool. Temperatures will reach into the low 20s Celsius at the beginning of the week, but after midweek most places will see temperatures slump in the mid to high teens. A real change after the humid heights of 30 Celsius for many parts last week.

Low pressure will lurk over or near to the UK bringing rain. Weather fronts will drape themselves around the British Isles with blustery winds taking hold, often from a northerly direction.

It will be a calmer day today, after the windy weekend. We have a brief window of high pressure bringing some fine weather. There is a good deal of sunshine over England and Wales, sunny spells poking out of the cloud for Scotland. Some of the cloud areas are thicker and giving a bit of patchy rain, particularly for Grampian. There is a quite cool start today considering summer holidays are arriving for Scotland and Northern Ireland.

Most parts of Britain will continue with bright, fair weather. It will feel pleasant with hardly any wind and top temperatures for London 23 or 24C. Other areas only 17 to 20C but with sunny spells. There will be a few light showers over Scotland, but the emphasis is on a lot of dry weather. Northern Ireland has an approaching frontal system. Here, with more cloud and the arriving warm front rain, temperatures will only reach 15 or 16C. The rain begins to reach Fermanagh and Armagh in the afternoon but takes until early evening to reach the North Channel. The winds turn to the SE, and there will be a period of persistent rain overnight for Northern Ireland. That rain then pushes over Cumbria and SW Scotland, turning wet here for the second half of the night

By Tuesday morning the cold front will have cleared Northern Ireland, so a brighter picture here and a brisk E or SE wind will be picking up over parts of Britain. It will be wet for much of northern Britain into Wales. Central, eastern and southern England will have a fair amount of cloud and feel warmer, but there is the risk of heavy showers working their way up from the Channel. These could be thundery. As always with showers, some spots will miss them, and others get a good soaking. So, a more unsettled day with blustery winds and the chance of rain, it will feel cool for northern Britain. Northern Ireland could reach 18C maybe a shade higher. Southern Britain could feel a bit close with temperatures around 20C but could go higher in any cloud breaks.

Through midweek the frontal system grinds to a halt over the UK and is joined from the east by another little low pressure. Overall there looks to be more rain and cloud over southern and eastern Britain, with brighter lulls for Scotland and at times Northern Ireland. It’s quite a messy picture as the rain bands swing over the UK. Temperatures stay lower as a more northerly flow sets in but by Thursday any sunshine in the north will still feel warm, as it is the end of June.

The output from weather apps will struggle with the detail for Wednesday and Thursday as trying to pinpoint one symbol for an hour, or 3-hour slot is too tricky. There may be a whole long line of showers, or a dry spell showing for the afternoon with rain in the morning but this could be the other way around. Themes are going to be a better way of looking at the next few days.

Not as hot, a cool breeze, especially for coasts- but not the south coast. Chance of rain and just quite an unsettled picture overall.

Thursday night looks cool, and by Friday there will be a brisk north/northwest wind. The weather does begin to dry up from the north and west as pressure starts to rise, but the risk of showery outbreaks continues for eastern Britain.

Next weekend

Still looks quite changeable, not hot, bit breezy and with showers coming in from the west but quite long, fine, bright spells.
