Good write up by GSP:

 

 

HOWEVER...THE MODELS (ESP THE GFS) ARE TRENDING TOWARD AN EARLIER/MORE INLAND NEGATIVE TILT PHASE...WITH CYCLOGENESIS OCCURRING CLOSERTO THE COAST AND PRECIP DEVELOPMENT EXTENDING FROM CENTRAL GEORGIATHROUGH MUCH OF THE CAROLINAS. IN FACT...THE GFS SQUEEZES OUT .1 TO.25 INCH OF QPF ACROSS MOST OF OUR CWA. ALTHOUGH THE NAM ISDRIER...EVEN IT FORECASTS AROUND A TENTH OF AN INCH ACROSS THEEASTERN ZONES. THIS IS A /BIG DEAL/ BECAUSE PARTIAL THICKNESS PROGSSUPPORT SNOW AS THE PREDOMINANT P-TYPE ACROSS THE VAST MAJORITY OFTHE AREA. EXAMINATION OF ENSEMBLE GUIDANCE (INCLUDING THE GEFS) DOESSUGGEST THE OPERATIONAL GFS IS A BIT OF A INLAND/WET OUTLIER.HOWEVER...THE TRENDS IN GUIDANCE ARE A BIT ALARMING...AND IT IS NOTAT ALL UNCOMMON FOR THE MODELS TO POORLY HANDLE THE TIMING OF THETRANSITION OF A SHORT WAVE TO A NEGATIVE TILT PHASE. WE WILL BEGINSLOWLY RAMPING UP POPS FOR SATURDAY...ESPECIALLY ACROSS THESOUTHEAST ZONES. WE WILL GENERALLY MENTION A RA/SN MIX...BUT ONCEWET BULB CONSIDERATIONS ARE TAKEN INTO ACCOUNT...THE PREDOMINANTP-TYPE SHOULD INDEED BE SNOW. WE ARE CURRENTLY FORECASTING 30-40POPS FOR ABOUT A HALF INCH OF SNOW...BUT WITH THE POTENTIAL FOR THISFORECAST TO BUST ON THE WET SIDE...AND THE FACT THAT IT/S BEEN ACOUPLE OF YEARS SINCE THE SOUTHERN PIEDMONT SAW MEASURABLE SNOW...WEWILL GO AHEAD AND INCLUDE A BRIEF MENTION IN THE HWO.

I just don't buy in to this event.  If we don't have cyclogenesis to our west and south it's generally not a big deal if anything.  Storm forming in the Atlantic is a recipe for disappointment IMO.  This winter has been bad, we're trying to squeeze blood from every turnip that comes by.  Now for eastern NC, that's a different story.  Raleigh even seems to get on that fun too if the storm goes boom off the coast.

 

I'll take some token flakes though, if I can get them in CLT.  Haven't seen them in a looooong time.   :cry:

Yeah this could end up like an event back in late 2000 where the Charlotte area was forecast to get buried but didnt get much at all, while areas east of I-95 in NC got lots of snow. Hopefully this one will be different.

yep much rather have a GOM low moving slowly across the gulf coast with cold air in place.  we all make out like bandits.

GSP write up above is from very early this morning around 0245. Next one this afternoon will be interesting. One has to wonder about Winter Weather Advisories as a possibility, 12z GFS is in advisory range-or better!

 

Just MHO it will probably take more than just this run to get GSP honking. I would think if the ENS comes in just as wet it's a good sign...but we're also playing against the NAM and RGEM..RAP looks close to GFS but it's only out to hour 9. This is gonna be a total wait and see event.
