You thinking we stay all snow tommorrow??

Unfortunately, no. There will be some sleet and freezing rain mix after lunch Sunday, but by then we should have a good amount of snow on the ground.

Mesoscale Discussion 1702
   NWS Storm Prediction Center Norman OK
   0208 AM CST Sun Dec 09 2018

   Areas affected...Portions of northern SC...western/central NC...far
   eastern TN...and southern VA

   Concerning...Winter mixed precipitation 

   Valid 090808Z - 091315Z

   SUMMARY...Snow, sleet, and freezing rain will continue this morning.
   Heavy snow, with rates of 1-2 inches per hour, should be most common
   across parts of western/central NC into southern VA. Freezing rain,
   with rates potentially up to 0.10 inch per hour, may develop over
   portions of northern SC into southern/central NC.

   DISCUSSION...A large precipitation shield has overspread parts of
   the Southeast into the southern Mid-Atlantic this morning ahead of a
   southern-stream shortwave trough over the lower MS Valley. Moderate
   to heavy snow has been observed over western NC and vicinity over
   the past couple of hours as cold air damming related to a strong
   surface high centered over PA remains in place over parts of NC/SC
   and VA. Enhanced snowfall rates of 1-2 inches per hour should become
   common across portions of western/central NC into southern VA
   through 13Z as strong lift occurring through a saturated dendritic
   growth zone supports efficient wet snow production.

   A transition to sleet, freezing rain, and eventually rain should
   occur from south to north for portions of northern SC into
   southern/central NC and vicinity as temperatures within the 900-700
   mb layer gradually warn above freezing. At 08Z, the surface wetbulb
   freezing line extends from roughly AVL to RDU in NC, and how much
   farther south it will advance this morning remains unclear. The
   timing of the changeover from snow to sleet/freezing rain also
   remains uncertain, but most short-term guidance suggests it will
   occur first in western SC (as recently observed at KGSP), and
   gradually spread northeastward into southern/central NC over the
   next few hours. Given the ongoing light to moderate precipitation
   noted on area radars, freezing rain rates up to 0.10 inch per hour
   may occur, but surface temperatures near freezing across this region
   may tend to limit ice accretion outside of the higher terrain.

I'm just east of you in Valdese what you expect  snow total wise before that happens? Also about a hour or so ago maybe around 3 had a heavy band come through did you have any sleet mix in with it? I could not tell if it was mixed in or if was just heavy snow and the wind.

Really nice snowfall around Duke Hospital - a little more than an inch on the ground and treated roads are snowed over.

Still all snow in Raleigh off Wake Forest Rd @ Six Forks Rd. Everything is white, road is covered. Probably 1.5"ish. Accumulating quickly!

I just woke up a little bit ago so I missed those heavy bands LOL. Right now it is snow moderately, but it is also snow. I expect another 5 or so inches before it changes over to sleet and freezing drizzle. Of course, if the warm nose pushes further north than expected, this could change.

Moderate snow with huge flakes crashed temps to 32 and everything but pavement now covered looks like we should switch over soon but if we could keep this up a few more hrs then the 3-4" runs were not to far off for us.....

Closing in on 4". It's been absolutely pouring snow out there and the wind is ripping. Temp down to 30.2 but CC line is quickly moving north

The HRRR did show it temporarily shifting back south before the "real" push north. Hopefully that happens. This is some really good accumulating snow.

I'm also impresses with the temp drop. Currently at 29.6.
