The issue is that without an established Arctic airmass it simply got too warm before start time. This wasn’t a situation where it started at 40 degrees and the wet bulb was 30. It was 40 with a wet bulb of 39. Upper and mid levels are fine, hence all the snow mix, but it is taking too much time to cool lower levels. Cold chasing moisture fail mode #1. Accumulation south of border looks minimal at best. Even Richmond struggled just north of main band though they are snowing good now. My cousin there said they have less than 1” even though it’s been snowing since 8 am. Only areas getting heaviest rates are getting big totals and there is a quick drop off on either side. Central and eastern NC could see some accumulation with some coastal development like the HRRR has been throwing out but this main area of precip isn’t going to produce much for anyone not in Virginia
