There have been 2 general setups like this one going back to mid Nov, and both resulted in a half inch of frozen here. This setup is a bit different, so an inch would be nice, but I have no expectations as it completely depends on how quickly the precip arrives/overcomes the dry air, and how heavy it gets at that time- and models are not in agreement on that. Beyond the first few hours its a quick flip to sleet then plain rain here. If the initial thump maximizes, then maybe the 2-4" call by Mount Holly might work out.
eta- I expect the Watch to go to an advisory here later today. This clearly looks below the threshold for a warning.
