Pretty cool living in Raleigh now and having real time data from RDU lol... That layer at 800mb is what i pointed out yesterday on the NAM bufkit skew-T. The warm sliver is just above 850mb's.  Once we can mix that out, we'll turn to snow. From there it just depends on the SLP track as to if we mix back with sleet or not after midnight. THis is for RDU airport area on up to the franklin/granville county line. Southeast wake is going to have issues until the 850's crash tomorrow.

SNIPPET FROM NWS-GSP:

NEAR TERM /THROUGH SATURDAY/...
As of 8 PM, the brief lull in the precip is coming to an end, as
additional precip continues to fill in along an axis from eastern
Alabama through N Georgia and into western NC. This will overspread
the remainder of the forecast area through the next couple of hours.
Locations above about 1500`, and roughly along and north of an axis
from Rutherfordton, to Lincolnton, to Salisbury in NC will be
solidly snow, while after an initial bout of rain and perhaps sleet,
a transition to snow is expected to occur down to near the I-85
corridor by midnight or so. South of there, considerable uncertainty
lingers regarding the timing of a transition, as wet bulb temps from
Anderson to Union to Chester SC are lingering near 40 degrees, and
there is not expected to be a tremendous push of cold surface air
into these areas over the next few hours. In fact we`re beginning to
get concerned that those areas won`t see any significant
near-surface cooling until the moisture begins to shift east of the
area. We will wait for the event to unfold a little more (and await
00Z guidance) before making any radical changes to the forecast and
products, but confidence that the warning will work out over the
southern half of the Upstate and northeast GA is beginning to slip.

Confidence is higher along the I-85 corridor, but considering the
warm nose indicated on special 18Z Raob from KFFC, and the fact that
sfc temps are going to need to drop another couple of degrees before
the transition to snow occurs, am concerned that initially rain,
followed perhaps by sleet, will cut into the snow accums in those
areas.

Meanwhile, forecast confidence remains high for locations
north of the I-85 corridor. Expect there will be some banding
overnight with frontogenetical forcing and slant-wise instability
developing, so locally higher amounts than the 4-8 inches forecast
in these areas will certainly be possible.

FAAAAAHHHH-KKKK!!! REALLY? There is ALWAYS a screw job in this SNOW TRIANGLE  OF DEATH lately!!! WTH??? I am located in the south of I-85 Corridor. SHEEEAT! GRRR. I feel for persons in Anderson, Chester and Union SC areas. UGH. I HOPE AND PRAY this warm nose erodes away, but the latest RAOB says otherwise. :(:(

Hey Guys, long time observer, first time poster.  I really appreciate all the information you guys provide and learning from you all!  There appears to be a big warm nose all the way back to almost Lake Lure/ Rutherfordton that is causing problems for Charlotte with regards to snow fall.  It's been sleeting for about 30-45 minutes, but no accumulation. I'm sitting at 35.9 degrees currently about 1 mile south of uptown.  I've lived in the Piedmont of NC all my life and it seems the battle line for big snow is always right around Charlotte where South Charlotte gets rain and North Charlotte gets snow unless we have a monster that dumps on Atlanta and SC.  It seems the cold air is really struggling to get ahead of the moisture here.   Best of luck for all of you out there, and thanks again.

2 minutes ago, No snow for you said:

Looks like we are heading for 2 inches of sleet. Yea. 

That's better than I'm going to see. We will not even get 1 sleet pellet where I am, much less any snow. We needed the cold air in place, or at least coming in on CAD. Coming across the mountains is not going to cut it here, despite what the models say. Still 40 here so I'm not even close to getting any sleet or snow.
