The main failure point would be a weaker wave that doesn't take on a neutral/neg tilt. If this is just a positive open trough, then that wouldn't be good for big snow totals.
Yeah the 00z ICON was neat. Built in neg tilt to the trough, and then basically repeats the storm track again on Tues night/Wed with the next system reloading.
Indeed. Not missing one key ingredient (cold air) sure does help. Must be what it's like for folks in ND/SD/MN all winter, pretty much every storm system is going to produce snowfall, it's just how much.
