runs to discard totally...6z eta (way out to sea).
runs to take with a grain of salt...0z eta and 18z eta (slightly outliers of the average)
runs that were close to mean ...12z gfs 12z eta..
gfs was extremely consistent throughout the day. there really isn't any trend to speak of, but I should note that it shifted a few miles S with each run.
eta not at its best on this storm. As you can see it took until 12z for it to really catch on to gfs idea and then the 18z moved it a little too far north.
so do what you want with this info, I just wanted to do this for the common good.
