    Sorry, but I see fragments of a smashed up PV, transiting across Greenland in your first chart.

    Consider where we were at that stage last year-

    That was a strong looking PV we had there.

    At this point, nothing in the charts gives me any cause for concern. Quite the opposite in fact....

    I wouldn't call it smashed up, I would call it under developed. Low heights start to dominate the arctic region prior to 120 so to me that is signalling the delayed but inevitable strengthening of the Polar Vortex and probably a return to a +AO. If modelling continues in the same vein then any weak ridging into Greenland will get flattened out as we head through Nov.

    Model watching has been good the past week or so but I don't think there has ever been modelled a full on Greenland block and the chart posted in the quote from last year, well, we could end up back in that position by mid month imo.

  2. To be fair, even if the broad scale pattern is to continue to be westerly I'd rather have transient HP ridging in from the SW than full on LP dominated Westerly / Nwesterly. I think quite a few people are looking for milder and less unsettled weather than full on southerly heatwaves to be honest. This cold wet weather is really getting to be a pain.
