The 10:1 Ratio is just not a fun model to use, the Kuchera Ratio tends to play nicer in my experience. Either way, predicting snowfall totals using solely these maps often does over-forecast for many reasons, especially the low resolution on these longer-range models you're using and the fact that not all snow that falls will stick.


As for what the broadcast media says, a lot of that depends on who the on-air met will be for that show, as they tend to make their own graphs and may interpret something differently or have their own model preferences, etc. The NWS will often (but not always) be more reliable since they'll have teams working on each forecast.


TLDR: Snow is hard to forecast!
