GFS struggling in FI- odd, 'cos no one takes it seriously anyway. At least in the TWO roll-out, the 06z frames got to T+300 then failed to finish before the 12z started creeping in.

Any sign of a warmup seems to have been binned on the 12Z GFS. And ECM is not too pretty either.

The words "school summer holidays" trump any synoptic charts. Fine weather will be back in the second week of September.

Looking dry for me (not particularly warm) after Wednesday's forecast rain. We'll see what happens further on....

A typical November morning outside: drizzle sitting on the grass blades, muddy leaves in the streets, but at least it's mild. No frost this morning.

Back to Model output, and the GFS ensembles show changeable conditions, and dry periods punctuated by wetter slots.  I note the model has decided this morning that a warm up (albeit temporary) may accompany the start of the month.  A fairly typical summer picture, in my view.

Very poor 12z so far low pressure stuck like a limpit to our NW . Dreadful for high summer especially when it promised so much.

 

Ukmo day 6 sums it up. In fact gfs is even worse my advice don't look.

Once again it's way past day 10 when we see any real inroads made by the Azores high

And back to the model output

Plenty of variety available in the model output this evening. In the interests of not tripping out mordant observations on the weather,

Here is the GEM at day 8 :

Which then develops into this day 10: Which would be increasingly warm and sunny.

At least there's P02 on tonight's GFS. The most extreme outlier ever seen on a NWP ensemble?

If you remember the fine spell as predicted by the models, there was optimism that it would have lasted at least until now. Its almost as if the aforementioned thundery low and the ensuing cold pool that took the best part of 4 days to cross the country erased the majority of the fine spell leaving a couple of days early last week and the current meagre offering at this end!

Both NAO & AO are are in negative territory, and predictions are staying negative.So this does not look good for return of the Azores high? Also looking at the charts there is a strong high over central and eastern Europe, which ever seems to do us any favours. Almost like a omega block develops, and we get stuck in the trough. What interests me though what is behind these flips as others have said, the thundery low produced flip and we are now on a conveyor of lows. Why has the Azores high stopped ridging up to us strongly as it did before?

Northern blocking as they say is supposed to the same as southern blocking with LP or HP moving eastward freely.  If the jet stream really exist then it should push the LP and HP cells faster and not stuck in same place?

Bland describes this evening's offerings. Standard westerly gripe, especially affecting the NW as is usual in our normal summer pattern. Uppers lacklustre throughout

Looks pretty mixed in the mid term. Based on the amount of site traffic I've been getting in the last couple of weeks I think it's fair to assume the weather is playing havoc with UK summer hols and outdoor events. Good for my business but unfortunate for people getting rained on.

There is a thread discussing the AMO in the climate forum for anyone who is interested.

The Law of Averages has come to pass. I'm expecting a mixed, rather changeable August myself. Maybe one more short lived heatwave before we wave goodbye to Summer 2017.

I wouldn't expect a summer to be wetter and duller than average...on average (as all but one has been in the last ten years, 2013). Average would be nice. This month is already wetter than average and last month was notably so. Even 2014 was a wetter than average summer here.

I guess to an extent I have forgotten what average should be like. I'd be happy with it never mind drier or sunnier than average, that would just be a bonus.

I'm trying to be positive but looking out the window, at the last 7 weeks of weather and the persistent output at the moment I genuinely wonder if we will go straight from spring to autumn (if we have not got there already). If there is any redeeming factor it would be that it has not been persistently cold, not does it look like being so on a daily basis. I'm watching the model output as I have done for weeks, hoping for something decent to reach this neck of the woods, and yes average rain and sunshine would be enough.

As a rare summer visitor ( as rare as a decent summer spell in Doc's backyard- I do feel your pain!!), I wonder if we have already had the best of what summer has to offer. Seeing as I'm off on a two week caravan trip to Eastern England on Saturday, I have been looking ahead at next weeks offerings and apart from perhaps a brief ridge for the South it doesn't look good. Furthermore I do genuinely feel for our Northern contingent- even during our previous better weather down here it was decidedly poor up there. The AZ seems to be holding back, flattened by the jet which again seems rather oddly placed for high Summer. I'm sure we shouldn't worry-  the AZ will be back with a vengeance come Winter to snuff out anything remotely of interest.

Thanks fotr the pointers David,I have had a look at the AMO, really vast subject, but just some basic observations, from the past AMO when it was colder, from mid 60's to mid 90's we got our best summers of late in that period? So a negative AMO means drier , warmer summers? just as a very basic observation. You would have thought a warmer Atlantic would be more beneficial but not quite the case. Some predictions are now saying we are heading to negative AMO, be interesting if it does we get back to drier warmer summers ?
