Just move that 0.5 precip line back west 2 counties to the Triangle and we are golden.
These changes on the modeling are wild this 12z suite
if we were on the snow line and saw this shift we would all be cliff diving 100%. if i am in the eastern carolinas i am loving these trends right now. not out of the game at all.

Yes. It's remarkable how those little changes in the northern stream make such a big difference at the surface. I guess now the question is will the northern stream dig a little more in the west? How much energy will be there? Will there be more ridging off the coast to prolong the event?
It appears the models are now pretty much at a consensus. How much will they change from here?
It's not a good model sorry if that offends anyone. Useful? Yes. Good? Meh
I need a complete RGEM coup of the models .. did amazing with last storm imo and was the only one harping steady sleet over freezing rain here in the triangle .. while the nam had .4 inches of freezing rain the day of the storm ..
Woah, that’s a major shift west 
12z RAP .. this is purely with the frontal stuff today .. still kind of going a bit at the end .. storm not in view yet 
That one has really perked up on the modelling today

The models are just picking up the bigger extent of the NW side precip field in overrunning events, something we know they underdo especially in mid range but always seem to forget when faced with these systems lol....need this to hang out for 3-6 more hrs ( at least )....the ratios get insanely good even on the NAM its 15:1 for several hrs just light QPF.....
The WRF sisters are outdoing themselves right now ?
Agreed. Honestly given what we’re seeing even CLT, especially east of I-77 is not out of the game for a bigger hit… that NAM run put the 1” about 20 miles to my east. If the snow/mix line was 20 miles to my east 18 hours out or so, I would be convinced that I would end up mixing a lot. Another thing is that from checking out the Bukfit data, there is some evidence that higher ratios may actually play out in the scenario. I always kinda dismiss ever seeing anything over 10-12:1 around here, but this certainly looks like it could be an exception and it could have an impact on accumulation forecasts… I remember reading that one of the reasons that the January 2003 storm busted with so much higher amounts than forecasted was not giving credence to the prospect of high ratios
Another example of poor ratio modeling was January 2009, models were showing an inch or two, and Raleigh received over 6 inches of powder.

12z RGEM - Northern Stream energy looks a little less diggy. My guess is that it will back off a little and line up with other models. Hold on a minute. It runs fast!
wow.
