I am not sure that this is the correct thread to pose this question, but I have a question on models and snow amounts forecasted. This upcoming storm obviously is super tricky to forecast amounts with the dryslot and downsloping issues, as well as the overall late transfer of energy to the coast and the warm air aloft overnight. But my question is about the snowfall modeling products in the NAM 3k, and the Ferrier snowfall modeling. I always like to look at the 10:1 ratio map, but it seems like in this setup the Ferrier numbers are really what we should be looking at (and seem to really reflect the low end forecast amounts coming out of the BTV NWS office.)
So any thoughts on when it is best to use 10:1 vs Ferrier in the NAM 3K would be welcomed, as well as how to best understand the differences in these 2 products. I attached the 2 different maps from the 12z NAM 3K.
