RGEM looks to have some snow showers on the backside

Seems like forecasted soundings are so borderline than any map we have witnessed seems probable.

The HRRR looked very borderline here too with line riding all the way down to just above the surface. Degrees matter every way.

ICON improved for NC!
I agree with this. It's going to be fun to see where we actually are late Saturday and early sunday in reality.

Starting in the early morning would optimize cooling.

I'd say so. 8 inches of snow with some sleet and a little freezing rain. That would be wild.

If we could miraculously get surface temps around 29-30 this could get fun!!
Interesting that they mention the WRF....

.UPDATE...
Main adjustment this evening was to expand the Winter Storm Watch
farther west and south given growing concern for some freezing
rain accumulations in a strengthening wedge Saturday night into
Sunday. This was based on some higher resolution guidance
advecting the subfreezing low level temps/wetbulbs farther into
the area, including the local WRF which has resolved past wedges
quite well. There is still much uncertainty with temps, timing,
and amount of moisture but the fact that models which typically
perform better with the local terrain and smaller scale
microphysical processes are bringing in some freezing rain mainly
north of the I-20 corridor and impinging into the far northeast
Atlanta metro was justification enough to expand. Also even higher
snow totals could be realized in the NE mountains. The watch area
could be upgraded to either a Warning or Advisory in future
updates so please watch for any changes. Previous discussion
follows.

That gfs run looked like snow north of 85. From hr 30-42 probably sleet to of course but not a bad run
It def put us back into a better situation initially
