Relative to the northern stream it doesn’t. If we just view the southern energy by itself then the gfs looks worse but when we view it relative to the northern stream it doesn’t. GFS is slower overall in the flow so the northern stream isn’t running as far out ahead of it as the euro is.
At 108h, the GFS has the southern energy near the 4 corners region but the northern vortmax is near the Iowa/Nebraska border…the Euro though has the southern energy a little bit east in NM, but that northern vortmax is over Detroit.
