Temps are busting WAY on the low side Here in WILM! 

Heavy rain rates off & on.. 

That CAD is AMAZING!

Doubt I'll see ANY Flakes, but My temps have crashed

From the "Forecasted 46F" overnight temps"

Temps  have fallin to 39F dew point of 37F and still Falling!!!!!

Strong ENE winds @ 13 mph..

Watching the Rain/Ice snow line creeping south, about 75miles away from the coast!

 

Hopefully you get a flake or two down there! That would be amazing.

If the HRRR is correct, the FV 3 will have been close to reality up here.  HRRR is consistent with 1.5-1.8" qpf with snow totals around 15" in the northern Triad. 

HRRR was showing the sleet line holding and not getting through wake until 7 or 8 this morning. You guys should have atleast another 4 hours of all snow after that so i can see it being a reality.

I'm pulling for it. If it's correct I'll get ~7" before the sleet takes over. And then I should stay sleet until most of the precip leaves. 

Currently around an inch on the ground. Snow is moderate but the flakes have gotten smaller. Temp is 30.6.

Hope it is right. Snows a few inches and then switches over to sleet. Didn’t show too much freezing rain either. Perfect scenario if it verifies.

 @shaggy,, My Brother, just Messaged Me, He's reporting Rain/SN mixed.. He resides in Sneads Ferry, N.C., He's currently under a bright "yellow" band  on Radar.. 

Looks  like I'm about get a Dry slot here for a bit..

Temps have  Crashed here to now 36F,,   Talk about a temperature forecast BUST

Snow falling Morganton, NC. Looks to be around 4 inches or so with compaction. Temperature is 32°.

Starting to hear reports of power outages, and that only looks to increase with the heavy wet snow. Trees are hanging low already, and we still have a good ways to go.

You thinking we stay all snow tommorrow??

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.
