Even the Euro and GFS have their collective biases that need slight correcting my friend. This is fairly well known. The GFS is still a little too far southeast with its tracks and tends to overdo the extent of its precip shield. the Euro, has a tendency to have a slightly over amped bias, not quite like the NAM of course, and tends to very slightly overdo the "LE" Liquid Equivalency. So, all these things need to be kept in a reasonable perspective.
