I agree with your comment that our airmass is marginal, but just a note that your map here is for Tuesday aftn, well after the storm
-
Prior to the 00z runs I said 1-3 of snow/sleet/slop for Charlotte, then up to 1 inch with the backside snow showers on Monday. I would now change that to 3-6 of snow changing to sleet, then up to an inch of snow on Monday. This precip should come in fast and furious Saturday evening and overnight.

Yeah, I don't think it makes any sense regarding how it's not good and cold on the backside as the low departs....I do agree more with the Euro compared to the FV3 regarding how the Euro scours the mid level cold and brings the warmth well inland. It looks like the UKMet agrees per UNCC's map (thanks for those)

Euro PType Loop
-
You can see here how the Euro doesn't hold the cold in NC as much as the GFS/FV3 as the 850 low treks east
-
Euro Precip
-
The backside snow showers / light snow looks good again on this run...we'll post a few maps shortly
-
Temps leave a lot to be desired in parts of the piedmont and east, but that's how the Euro has looked all along
-
It brings the 0 deg 850 line well inland again, but there's heavy comma head snow for Frosty and the foothills
-
18z was a wet run of the Euro and this one looks just as wet if not wetter out to 60 where it's snowing heavily in NE upstate and western NC, over to CLT and RDU and NW into S VA
-
Euro out to 48, compared to 18z, it's maybe just a touch colder thru NC (thicknesses) and precip shield is a touch south...small diff
-
That's a long event
-
There's the post we've been looking for. Nice! Straight up, I love where you are located with this one (as usual). Precip is going to be farther north than currently shown IMO even if the track is the same...and you have better ratios there...just wait it out

UKMet Precip
-
Noteworthy jump for a 6 hr model run separation this late in the game.
-
Nudged south maybe it looks like??
-
UKMet has the low on the southern LA coast at 48, then a decent amount off the coast of Charleston at 72 - probably similar to previous run
-
UKMet at 72 isn't close to the Carolina coast with the sfc low....can't see 24 and 48 yet, which I know is weird
-
Good backside snow showers flying on the GFS through the day Monday in E TN, N GA, W Carolinas
-
Good front end snow thump for CLT to RDU on the GFS
-
It's a little colder and south...h5 heights along the east coast were south thru the run...amazing how that has continued
-
I dug it out - see our own Isohume's comments here - https://www.americanwx.com/bb/topic/43038-saturation-with-respect-to-ice/?do=findComment&comment=2835083
-
you should maybe add "for VA" on the end
-
It looks wrong to me, plus you need ice nuclei for sleet just like you do snow (so you need saturation in DGZ for both)...that's my understanding (i.e. sleet has to come from melted snow)
-
That looks like plenty of RH in the DGZ there IMO. Saturation with respect to ice is 80% RH...saturation with respect to liquid is 100% RH....believe that's how it goes.
