How could it be a myth? It's basic physics. We have liminal temps, it didn't get below freezing until recently, and when I laser temp a surface it's well above freezing. There's no snow accumulating on anything that retains heat. Yes, snow falling at decent rates would overwhelm that, but that makes a significant difference, since we don't have remarkable rates even in the bands right now, and it's a long duration low intensity event with lots of breaks for melting. There is a large break between this batch and any further sustained snow tonight. Road conditions would be more of a concern if antecedent temperatures were cold. Would they magically melt poundage? No, of course not.
