Agree, also with a couple of inches if ice pellets and some ZR on top of that, the forecast of cold temperatures the next 2 days following would leave 2" of frozen cement
Agree with the thoughts on the interior sections with the icing potential. The CAD is tough to scour out in those areas. The only thing that might hold down the icing are the temperatures forecasted to be around the freezing mark instead of being in the mid 20's
I'm not sure if I'm correct but most of the snow maps that are put out there are mostly at 10:1 ratios. It's hard to get those ratios in most events. So people are looking at the maps and not taking the lower ratios into consideration.
