First inkling of some wintry weather around the day 8 mark....ECM (top image) shows a split in the lows and a brief stalling of segments of vortex moving west to east, this allows the Arctic high to attempt a westwards push....doesn't quite get there but an interesting possible battleground scenario setting its self up if the high can push a little further west before the next trough arrives. GFS below, some idea but not quite as good.
