Looks fantastic! But one thing I have learned is never to trust a long range GFS run...it will probably be different in tomorrow's run.
However, looking at ECMWF in the week up to the Olympic start, as well as those fluctuating GFS charts, there seems to be some consistency in the fact that high pressure will make some sort of a comeback.
The Met Office are being cagey in their long range outlook, but have started to introduce hints of better weather in the south.
My gut feel is that August will be a marked improvement on June/July, with some advances of the Azores High, though no great heatwaves. There ..I've stuck my neck out, will probably be proved wrong !

... well, the obvious reply is ... it *could* be true! But it would go against Lamb's singularity for that period:-

THUNDERY, CYCLONIC WEATHER OVER EUROPE & BRITISH ISLES
Stagnant lows common. Cyclonic type very frequent, especially around 4th - 8th August. Westerly & North-Westerly types also commonly occur.

However, the fool inside me says - surely we can't have much more of this rainfall!?

Well, that would be nice - after yet another day of rain ...

At the last London Olympic Games, in 1948, the ‘austerity’ games (29 July to 14 August) opened at the climax of one of the most intense heatwaves yet experienced in England.

On the day of the opening ceremony, the temperature reached 34 °C at Camden Square, not far from the main athletics venue at Wembley: at Kew Observatory, it was the hottest July day on record to that time. Unfortunately, the fine weather was short-lived, and by early August the weather had turned cool, dull and wet. At Greenwich, 40 mm of rainfall was recorded on 6 August, two-thirds of the average for the whole month of August.

Being optimistic, Lamb also says for June "25/6 -1/7 sunniest week of the year" & "12-29/6 "Years highest frequency of dry days in London" so lets' hope 2012 continues to defy normality!

On a slightly more serious note, there do seem to be increasing indications of a gradual improvement, unless of course you live in NW Scotland.

As for the Olympics, I'm escaping to Scilly, hoping for some good snorkelling conditions.

... the subject for us in Dorset is certainly a 'live' one; roads in and around the Weymouth area (sailing venue) have been significantly affected recently due to flooding - the main 'arterial' road, the A35, which feeds traffic to/from Dorchester from the east (used by traffic going to Weymouth) was closed for a time with local roads being unable to cope with the diverted traffic. Car park facilities in Weymouth itself have been under water.

A period of no rain, or bigger gaps between the rainy periods would be most welcome!

After a virtually dry 4 days (Saturday 09:00 - Wednesday 09:00) the last 2 days have seen 34.2mm. This means that whilst June wasn't that wet here (113.8mm) July has already surpassed it at 121.1mm.

The wettest July here, by a very substantial margin, is July 2009 with 227.9mm (303%), so that will take some beating. We saw 29.7mm on 11th, 51.8 on 16th, 48.4mm on 28th. Mind you, it was a good deal warmer & sunnier as well.

T+240. Now can this be true?

I think confidence is growing!
I gave my work colleagues a slightly tongue in cheek forecast for the opening ceremony: dry, sunny spells, 25C!
We shall see! But the jet stream is definitely moving north, which is a good sign for us in the south (and will also break the drought in the Hebrides!)
