I think some people are misinterpreting Frosty's posts, thinking that he is saying a return to summery weather is a definite outcome...
All I am reading is someone who enjoys discussing outputs and possibilites that may bring more settled weather. Yes I doubt anyone reading this thread would rely on charts that far out, but outputs at the far range of the runs are a type of longer term signal nonetheless.
There have been for a few runs now showing a push of higher pressure from our W towards the end of August. It is too unreliable to consider at this stage so as others have said, we will need to wait a few days at least before it becomes clearer on whether it is likely/unlikely to happen. Just like when unsettled weather is shown that far out...just as unreliable right?
I am not exactly seeing washout synoptics that we have been accustomed to in other recent Augusts either. At least we don't have depressions diving to our SW and then bringing frontal rainfall again and again as it swings back up over the UK.
