I would also like to agree with you. However, the latest runs from ECM are hinting at something a bit different. Even GFS is hinting at it, but perhaps in a different way.
Ex-T storm Chris has failed to deliver the disruptive influence to the block we have enjoyed now for so long. But it may just be that the injection of energy from Chris has changed the character of the block itself. In the latest runs the SW/NE block has shifted a little bit further east. This may introduce warmer air from continental Europe, which is now getting hot. This is one important component we have not experienced so far this summer. Our warmth and dryness have all been largely home grown. Hence the lack of a really big heatwave 'a la 21st June to 9th July 1976'. We've had consistently warm dry and sunny weather, hence the above average temperatures, but nothing truly spectacular.
Now we have the prospect of real heat. Conversely it could all break down, but somehow the gut feeling is this won't happen. All the ingredients for real heat are in place: the bone dry and warm United Kingdom, the rising sea temperatures, the hot continental Europe, a subtle change in the orientation of the block. There is nothing also on the horizon to bolster the jet. Everything is in place for the development of a serious heatwave, and this is the indication from ECM this evening.
