This is significantly less coverage and what the model is showing last Friday or last Thursday and it's also somewhat less coverage than what the model is showing on Sunday afternoon. Mind you the actual rainfall amounts are about the same with some areas seeing anywhere between 0.50 and 2.5" of rain and clearly the heaviest rains are going to be over Buenos Aires Entree Rios and southern Santa Fe.
