This is more of an idea than an improvement, but I think it would be good if TWC's precip maps indicated freezing rain accumulations instead of using rain as an indicator. It would make it easier to know where there's a chance of little or a lot of freezing rain to develop. I think the way it is now gives a false impression that's it's a warm rain when it's really ice. I would suggest using different hues of purple or pink as they do on radars.
