Temperatures Easing BackAdded : Saturday at 14:45 Some exceptionally warm air across many parts of the UK today with temperatures across parts of England this afternoon into the mid-twenties, and combined with blustery winds it feels rather tropical out there. It's not the same for everyone though with many northern and western regions of the UK seeing a lot of rain thanks to the warm, moist air mass.
Here is the synoptic chart from earlier on today:
If you trace the isobars across the UK back then you can see why it's so warm. Air from the tropical Atlantic is feeding up from the south and southwest, and for good measure Hurricane Leslie is off the coast of Iberia which has plenty of warmth and moisture wrapped up within its circulation:
This warmth is also affecting many parts of Europe:
However, by the second half of next week, cooler air will have moved into much of western Europe:
All thanks to changes in weather patterns with high pressure building to the southwest of the UK and low pressure away to the north helping to draw in cooler air from off the North Atlantic:
For Britain and Ireland the change to cooler conditions takes place during the rest of this weekend as the frontal system that has brought so much rain to some western regions during the last couple of days eventually clears away to the southeast. However, this won't be before another wave feature forms along the front and pushes north-eastwards on Sunday, bringing some wet weather to central regions:
However, for the southeast of England, it could be Monday before this front finally clears with model guidance hinting at yet another wave feature bringing a pulse of heavier and more persistent rain northwards:
The change in temperatures will be noticeable, these are the current values out there this afternoon:
These are the forecast values for Monday afternoon:
Changes on the way then and next week should feel something more akin to what would be expected in mid-October, especially in the southeast where it has been so warm, whilst a welcome change to somewhat drier conditions is on the way for the north and west although any sustained settled spell looks unlikely.
