The northern stream is the main culprit for the lower totals. But then again, if it isn't squashed, it's probably a mixed mess even for the foothills and mountains. No true CAD high in place.
We need more of a NNE movement of the precipitation not ENE. That's one reason it's so dry over NC. Plus the trough is too progressive and trending more positive last few runs
I just have that nagging feeling that something is going to screw us still. Don't like the 18Z euro going dry again. It looked like the UK with a dry area around the escarpment too.
Hopefully the trends will be good at 00Z.
Here are my reasons for optimism-
1. Snow pack to the north and cold in place
2. Cold (frozen) ground and sun angle are ideal for quick accumulation
3. Majority of the precipitation falls at night. Easier to stick.
4. Confluence should prevent it cutting too far north/west
5. The air is dry out ahead and will allow for evaporative cooling.
