this is probably the only time I will ever say something like that is possible. but yes, if you do have that strong of a closed low, dynamic cooling does occur. it's not voodoo or anything
like this is a sounding from NC where the GFS drops 6-10". that's more than cold enough and that's in the Carolinas. cutoffs do really weird crap
so yes, I would absolutely take my chances with a ULL like that. the amped solutions are what everyone should be rooting for, because there is a 0% chance with a washed out POS
