The updated clusters now 70/30 on the nw euro upper ridge in the extended and prior to that, the direction of travel is nw euro trough suppression (as alluded to by Tamara) and the sw/ne axis of flow is now the precursor of that 70/30 split in the same ratio 

yes NWS and i hope it comes off as i would be on afters but booked that off

here are this mornings EPS 500's and temp anomalies and as you can see +ve heights into Scandi with upper flow from the SW and above average temps

@MATT☀️

just

That is a cracking D8/D9 mean. Maybe we aren't done with 30C this year yet? Long shot, but the kind of chart that might do it

Temps of 24 degrees in Northern England and 28 in London next week . I thought we were meant for strong winds and rain this weekend coming now high pressure noses in from the Azores

ECM looking very nice indeed into next week. Some warmer air making a move over the UK. The mid month warm up and change to settled weather corresponding nicely again to a sharp rise in AAM:

Perhaps one final shot at a plume too. Not that I'm desperate or anything!

2018 had one in April, so I don't doubt a September will one day pull one off with the right set-up

Signs of a positve pressure anomaly developing to our East. At least it should be warmer unsettled, but theres a prospect of a plume or even longer spell of last minute warmth IF pressure develops further to our East.

Well after i posted that a plume did appear, and indeed the ECM in particular suggests high pressure both to our East and building in from the West.

Very nice, however these charts simply do not agree with the ECM, and suggest the GFS transitory plume is more likely. There is no high pressure domination on these charts, but troughing, albeit weak, over the UK. A moderate Westerly upper flow . So personally i wouldnt get hopes up too much for the current ECM solution, whilst it may be proven correct or nearer the final solution then the NOAA charts, the chances are stacked against it as historically in these situations of disagreement, the NOAA are by far nearer the mark.

I do think the GFS is gradually moving towards the ECM though- if it was the other way round I'd be more concerned. Monday at the very least looks nailed on to be a warm/very warm day across the bulk of the country.
