Remember the storm modeled on or around 3/17/17 that was showing 12"+ for a good part of New England, then completely evaporated? I think it was withing 48-72..I know not the same idea but that was a pretty drastic change.
Meh. One model model outside of its range. Need to see that with RGEM/GFS to make anything of it. Though technically the RGEM is still outside its range too. Gotta see the whole 12z suite including AI models.
