That 18z GFS blew up the Monday storm at hr 84 to 932 mb off Labrador, even stronger than what it had at 12z. So I don't see that high retreating E much, if it all from here. In fact, that low is so strong and slow to move out up there that our Wed-Thur storm will be shunted east and will hit Great Britain on Sunday as a strong 976 mb low.
