I think it depends on where you are located. Each model had flaws. I think for AVL/East towards Raleigh, the NAM scored in terms of calling for the transition to sleet and the warm nose/generally lower totals.
The HRRR was trash in terms of amounts, except did fairly well for Atlanta. I just don't see how anyone considers this event anything but a bust unless you're in Atlanta or west.
Upstate of SC did not get anywhere near the amount forecast. The foothills fared “ok” but generally lower than forecast. SW mountains were hit or miss. Charlotte was way under. Raleigh didn't get what the models were showing 24 hours before the event. Generally, an underperformer.
Look at how much Justus, Boyer, and Panovich were calling for just to see why many are calling it a bust.
