Seems based on research, that heavy sleet accumulations are rare in NC. February 1987 is a prime example, where up to 6" of sleet fell in Wake county. A very similar setup to this one too, based on the charts in this paper: https://apps.dtic.mil/sti/citations/ADA250184

It's a bit confusing, but as I understand it, FV3 refers to a trial version of the model. So every time they're working on an upgrade, they'll release both the old and new versions at the same time and eventually make FV3 operational. What I assume is being discussed is the WRF FV3 that shows on pivotal weather. I believe this is a trial version (hence FV3) of a high resolution GFS model

Our trough that will become the primary low is now over the Northern plains
-
Supposed to be like the hires NAM but run off the GFS. I've found it to be straight trash
-
True, although I suspect heavier bands of precip will fall as sleet. FRAM for comparison
-
Looks about how I think this will shake out. Although I would cut freezing rain acreation in the jackpot zones in half
-
The RGEM runs the low directly over Raleigh, lol
-
Crazy how the mesos bring the zr line all the way down to Myrtle at the onset, but yet the triad flips to sleet almost immediately
-
Yeah, I almost feel like the surface low being further south initially, hurts the potential for a good initial thump for those of us north of 40
-
Apologies if already posted, but he's one of the best snow forecasters out there IMO
-
Nasty sounding fro Raleigh. Good to finally get some clarity on precip type, with the 3km NAM coming into range
-
2 days ago we would have been celebrating the placement of the ULL on that map. What went wrong? Just look at the decrease in heights. Not too shocked to see blocking fail to materialize in a La Nina year

Actually seems like a pretty easy forecast for the most part with the convergence of the models. With the caveat of figuring out how much ip vs zr
-
Seems like regardless of track, the trend had been to reduce the size of the snow thump area at the leading edge. Why is that?
-
Pretty torchy in the mid levels though
-
GSP is bullish
-
Haha, yeah, it's drunk. There's a reason it's called happy hour, and as per usual the 18z NAM is the main offender
-
Live by the NAM, die by the NAM
-
Gives some sense of where the freezing line may end up at it's warmest, although I suspect you could shift it *East* about 50 miles
-
Also I think sometimes convection along the coast can reduce precip totals for the Piedmont. Something to watch.
-
No surprise that when eastern Kentucky gets heavy snow, there's significant mixing issues
-
Accuweather's "Wintercast" feature is actually decent. Gives probabilities for accumulation ranges. Calling for the most likely scenario of 1-3" of snow and .5"-1" of ice, which is a little gung-ho on ice for the triad.

With the complexity of the low transfer, ensembles become less of a factor from here on out I think
