  1. The 500, 700, 850, 925 and surface lows are aligned now from nwSC to off the SC coast and the slope (imagine this to be a very large F1 tornado tilted to west at highest point) is slowly decreasing as each level catches up to the one closer to the surface. Surface banding is tending to be squeezed together by this process as the further west the snow, the more connected it is to upper level lows. This should slowly fill in that long-lived dry slot near Raleigh and allow them to join the party (a bit late so totals will be 4-7"). 
    This storm will continue to rip for 6-9 more hours before the 500 mb low drifts out to sea. Some places could end up with 18-24 inch totals as heavier bands will develop now that stronger winds are blowing in from the ocean.
    Some gusts to 50 or 60 mph likely in exposed coastal areas this evening into the overnight. Severe blowing and drifting of snow will occur. Wind chill values of 5-10 F or lower, seldom if ever observed before in coastal NC are possible. Further inland it won't get that windy but gusts to 35 mph will be widespread, blowing and drifting snow will strand some travelers, and wind chills will drop to near or below zero F. 

    Check please!
