With those numbers it’s virtually impossible for me to reach the freezing mark. Speaking for mby only. 3k NAM now looks like no one in SC ever hits the freezing mark. Looks a lot like the HRRRNam handles the mid-level thermals better than the globals do. That's been proven many times over. As for the boundary layer and cold air damming, that's still up for debate. Let the storm play out and we will see how it compares.
