This will have to be watched because as impressive as the current maps appear, if this feature were to hold together somewhat longer it would engulf Britain and Ireland in a very strong northerly of sub-freezing temperatures which is almost what the maps show now ... the only difference being that the northerly is rather strong instead of very strong. I can't stress strongly enough that this will be a major winter weather onslaught and not just a drop in temperatures with a few local flurries. This is like turning the eastern Atlantic into the Great Lakes, almost, when you have this much cold air rushing south this fast, it overcomes the normal tendencies of the Atlantic to modify air masses and turn streamers to mush. This setup could give blizzard like conditions even with winds somewhat west of due north, in many parts of Ireland. And we aren't that confident that the setup is perfectly modelled yet, what's probably equally likely at this point is that the polar low will drop into the North Sea and pull Siberian air across into the N-NE flow on following days. There is also a lot of super-cold air waiting to head west from central to northwest Russia and around Novaya Zemlya. When this polar hurricane develops, winds are going to be 50-70 knots around Jan Mayen with temperatures of -12 C ... the ice margin will probably shift south in this period to reach limits not seen in recent years, and the Baltic Sea is rapidly freezing and spilling out 0-2 C water into the North Sea. All of these factors are building blocks towards what may become an epochal cold spell for Ireland and Britain in the next 20-30 day interval.
