From a synoptic standpoint, Monday has some pieces in place to produce pretty well actually...you have good confluence north to enhance any WAA fronto and the shortwave becoming stretched so you will get a deformation probably oriented E-W that drops some pretty good snows on someone. The key is keeping the shortwave intact enough. Prior runs were just grinding the thing up, but it's trying to keep its integrity better now on some of these runs...even the 06z Euro trended that way.
