We discussed yesterday in detail regarding the huge model differences between the European and the GFS model and how the trough in the west and the block were critical to the forecast outcome for next weekend and beyond. It appears now that both models had different aspects of the pattern wrong and overnight weather models begin to line up in a slightly different way and that trend continues this afternoon.
