It'll be a cool, wet summer, the long range models said... everything indicates we'll be stuck in a trough after early June, they said... no signs of anything decent this year, they said.


More discussion of such models, and the more useful shorter range ones, in here please.

In the longer term, the models are hinting at the trough complex to our east enticing the jet stream to track more west-east than southwest-northeast, putting our high pressure under, er, pressure. The thing is though, that sort of progression has come and gone from the models during the past month without any verification. That said, it's far from an impossible development, so it's worth keeping an eye on.

Sorry for being a bit off topic, but not all the long range models got it wrong; CFS showed +ve height anomalies over the UK in July starting way back in April/May and never wavered since - accompanied by above average temperatures. I'm very impressed by it's performance there. That followed a signal for higher heights to the SW and NE in June, which also verified pretty well.


I think the Met Office ensemble model was actually quite similar to CFS but with the +ve height anomalies more to the NE in July. It didn't show above average temperatures though.


CFS is giving a rather vague signal for August but does have a weak trough signal to the NW so that's something...




Hopefully that venture is allowed in here - it is discussing a model after all


Now then... the morning runs reveal that GFS and UKMO have shifted to follow ECM's idea of troughing getting to our NE and developing thereafter - but the consensus is on the trough complex being more towards Russia than the UK, which allows high pressure to remain dominant across the UK with uppers near or above 10°C for the majority of us.


In the longer term, the models are hinting at the trough complex to our east enticing the jet stream to track more west-east than southwest-northeast, putting our high pressure under, er, pressure. The thing is though, that sort of progression has come and gone from the models during the past month without any verification.

I recall your comments on the CFS output a couple of months back. As I recall you put some comparison/anomoly charts together off the back of them. The broad picture now is a good match for those, but the high I think was progged to be a little more north and east. We both expected a little more in the way of thundery disturbance from our old friend the southerly tracking low I think. 


As it happens I've noticed some talk about Simon K going for very much that going into the last week of the month. It isn't vanishingly unlikely, but over the last couple of days the high seems more likely to slink away to the west than venture too far north.


In the meantime

Intriguing this - the pattern is reminiscient of that seen in early June this year.


It's ripe for a jet split and indeed it's already underway in the above chart.


Then we hit FI and the model struggles to resolve the complex nature of the jet split. It then can't help but throw those waves in the jet eastward so the blocking to our NE never stands a chance.


IMO if the block held we'd be looking at thundery troughs from the south as Simon Keeling mentions (thanks for the heads up Waine - and yeah I guess I can throw a little more weight around now that I'm a mod )




I'm far from convinced about the idea of a standard westerly breakdown

That said, Gavin P did a round up of the summer in May (and April), and I seem to remember very few models going for a decent summer and certainly nothing like what we have. If memory serves (and Gavin will have totell me if this is right), most seemed to suggest we would not have high pressure over us.

Just a heads up that my good friend Tom from Essex Weather has asked me point out that ECM ensembles are now publicall avaliable at Essex Weather;

So if it ran to the 26th (and of course there's no guarantees either way at that range) it would be three weeks of very warm or hot and dry weather for most.
