I have the spreadsheet whipped up and ready for the forecast contest results, but I just need the final snow numbers once the storm is done.

Using Weather Underground, here's what I've got...

AVL: 2.2 snow, 0.08 liquid, 28 to 1 snow ratio

GSP: 3.1 snow, 0.29 liquid, 11 to 1 snow ratio

CLT: 3.5 snow, 0.38 liquid, 9 to 1 snow ratio

GSO: 6.0 snow, ? (bad data), ?

RDU: 5.0 snow, 0.49 liquid, 10 to 1 snow ration (STILL SNOWING)

DAN: need source for data (STILL SNOWING)

PGV: need source for data (STILL SNOWING)

ORF: 1.5 snow, 0.05 liquid, 30 to 1 snow ratio (STILL SNOWING)

RDU is surely higher than 5" now. That was as of 5 PM and there was still moderate snow going then.

6.75” here just 2.5 miles east of Youngsville, NC off Hwy 96.  Definitely a great storm.  Played in it all day with the kids and other adults. One that will be remembered.  Pic when I can. 

 

NWS and WRAL both showed 11” close to where I live.  Not sure who measured that or reported it but they must have gotten under a heavy heavy band.

2.5" down, looks like more is coming according to radar. NE NC could seriously overperform.

   Areas affected...The Outer Banks area of North Carolina into the
   Tidewater area of southeast Virginia

   Concerning...Heavy snow 

   Valid 180309Z - 180715Z

   SUMMARY...Heavy snow rates in excess of 1 inch per hour, including
   occasional heavier convective bursts, may develop across the North
   Carolina Outer Banks area, possibly into portions of the Virginia
   Tidewater, during the 11 PM to 4 AM time frame.

   DISCUSSION...A significant mid-level trough is forecast to continue
   pivoting east of the southern Appalachians during the next few
   hours.  As it does, models suggest that it may take on more of a
   neutral to negative tilt, accompanied by an increasingly better
   defined lower/mid tropospheric cyclonic circulation center across
   the piedmont through coastal areas.  This appears likely to
   contribute to a consolidating area of upward vertical motion, with
   considerable strengthening by the 05-08Z time frame, centered across
   the Outer Banks area of North Carolina.

   Aided by dynamic cooling, cold advection and melting precipitation,
   thermodynamic profiles near immediate coastal areas are expected to
   cool entirely below freezing, supporting snow or a changeover to
   snow.  Rapid Refresh forecast soundings indicate that lift may
   become maximized within the dendritic growth layer for several
   hours, supporting snow rates in excess of 1 inch per hour, in the
   presence of precipitable water between .5 and .75 inches.  At least
   some convective enhancement appears possible leading to occasional
   heavier bursts of snow, before diminishing/spreading offshore after
   08-09Z.

   It is possible similar snow rates could impact portions of the
   southeast Virginia Tidewater, but the most prolonged/heaviest snow 
   appears most likely to the south, across the Outer Banks area
   near/north of Cape Hatteras.

Two feet of snow under the deck. Fascinating.

Just amazing what you guys are getting.  Rarely come to the Southeastern forum but just had to see what was going on with this storm.  It has been over performing all the way from Paducah through TN to the coast.  It is so fun hearing everyones excitement and stories.  Glad you all scored!

Finally made it to Nags Head via hwy 64 E.  It was a rather harrowing drive through the convective banding that set up near Columbia and points to the E of there.  It was blowing and blinding SN+ in that band, where I could barely see 25 feet in front of me, didn't help that the road was completely covered and pitch dark along that rather desolate hwy!
