Friday was always the day that was billed as the peak of any heat this week. This could still hold for SE England. However, for the rest of the UK it isn’t looking quite as warm. The Atlantic low will have made more progress towards the UK, bringing cloud and rain, and a more Westerly influence. The east/southeast winds which were going to sweep all the continental heat over the UK, now are struggling to do their thing. There is still hints of mid-twenties Celsius for south-eastern Britain on Friday, feeling warm and humid but each day this week the area of real heat has shrunk away to just the SE, no longer including the Midlands and eastern plus southern England. Central/southern and eastern England still look warm at 17 to 20C but a lot of W.Britain looks cooler with more cloud and frontal rain. Wales 14 to 17, N.Ireland 15C and E.Scotland up to 16C. The threat of heavy showers or even thunderstorms coming up from the south in the warm humid air, is still present but with low confidence.

So for many Friday is now looking more unsettled and that seems likely to affect the temperature climb.

The warmth was never forecast to hold in the north and the west of the UK but it seems to be avoiding the south and east too as we head into the new week

As the low centre nears NW Britain Friday night it becomes windy for W.Scotland and N.Ireland

Low pressure swings by over the weekend

Saturday sees bright and sunny spells with blustery showers from the west. Some heavy showers for N.Britain. It will feel cooler in the brisk SW winds but eastern parts will fair okay and the SE will reach 19 or 20C and feel fresher, less humid than Friday.

Saturday night looks chilly with a brisk NW wind picking up for Scotland. This brings a slightly different distribution of showers but mainly Scotland and N.Ireland and more scattered than Saturday. It will feel cooler for everyone
