EURO is the model of choice because on it's last run it showed the most logical solution--- the primary LP continues moving towards the block - until it senses the block and then lets the energy take over down south of it developing a secondary and then that secondary moves underneath the block ....BUT according to this run there is only borderline cold enough air in place over the metro so it shows a frozen mix at that point. BUT the primary does initiate a period of snow here before the secondary approaches and slides underneath the metro......
