Given the high pressure that looks to set up to our east (and especially if it sits over Scandinavia) seems likely to be a fair deal stronger than the one that brought the July plume, I would be surprised if the Atlantic found it so easy to sweep through this time. Wouldn't be surprised to see the Atlantic attack delayed somewhat - has happened a fair few times before if I am correct.
Also looks to be a possible good scope for a rinse and repeat pattern. Even if the Atlantic does break through somewhat, I am not seeing troughs wanting to sit over us. The core of low heights looks to be well to our NW in the upcoming period.
