Heavy Freezing Rain at 30 deg isn't actually a huge problem on the surface as most make it out to be. Too much latent heat release happening. Trees / Power-lines are a concern, but you really need to be 28 or below for stuff to stick in moderate to heavy rain. The worst case is <28 and light rain, that's when you're in trouble.
I think we're seeing a trend north and west with the WAA. If the surface holds at 30, might be few isolated areas that are a mess, if it gets to 32, we'll be fine disappointed.
