The GFS thinks a ridge and higher pressure will start to build from Tuesday 13th next week. This will bring drier conditions and temperatures reaching the high teens. Even higher pressure looks like building from the weekend when we could start to see temperature in the low twenties.
Other models see higher pressure from early next week but they don’t agree on the higher pressure during the weekend.
The image below is a 9 day panel image and you can see high pressure building on Tuesday 13th.
So confidence for improving weather conditions from early next week is reasonably high but uncertainty for the weekend at this time.
