Bij deze nog een interessante bijdrage.
However, coincidentally the lower stratosphere has been showing signs of splitting at the same time and this has now extended up to the 70 hPa level. It is splits like this that have led to the cold outbreaks that we have witnessed in the last few years, so it should not be ignored.
The GFS has been hinting at this as well.
The question remains how this split can affect surface based systems on the tropospheric level. The orientation and formation of the forecast ECM split certainly is giving an opposing signal to the current Scandinavian high and retrogression would be favoured if the stratospheric charts are to be believed. Though this looks like going against current troposopheric signals. The longer that this stratospheric pattern is delayed and the closer that this occurs to December, the bettter chance I think of retrogressing occurring.

„Et nul ne se connait tant qu'il n'a pas souffert, „C'est une dure loi, mais une loi suprème, „Vieille comme le monde et la fatalité, „Qu'l nous faut du malheur regevoir le baptéme, ~Et qu'a ce triste prix tout doit étre acheté. „Les moissons pour murir out besoin de rosée, „Pour vivre et pour sentir l'homme a besoin de pleura, „La joie a pour symbole une plante brisée, „Humide encore de pluie et couverte de fleurs."
